Mars

Its been a while since I tried Mars, and its usually been unsuccessful, anyway I thought I'd try again as it was somewhere useful.

I tried first with a standard setup, but wasn't seeing much, and it was really cold, and I couldn't get the focussing right. Anyway, I thought I'd have one more go with a 2x barlow lens in the mix with the webcam, and although the results didn't look much on the screen at the time, I was quite impressed with the results.

See what you think.

Venus again

So this time, I lugged my telescope upstairs onto the balcony and took some shots of Venus. At last I managed to get more than a rather blobby shaped blob. In fact you can clearly see it is showing phases like the moon here. All this while trying to supervise my son writing thank you letters and juggling USB cables. Taken and stacked using a webcam and registax, but taken over the roof of the house across the street - not the best for avoiding heat haze!

Anyway - at last a good shot of venus.

Venus and the moon

It was my sons birthday today (8) and he wanted to go out to Pizza Express. Just as I got home though, I could see Venus and the moon for the first time for days. So I got the camera and tripod out whilst the rest of the family were deciding what time to go out, and what to eat.
With my new USB extension cable, I could actually connect the computer up to the camera directly, and download results straight away, which for small objects means you can check on focus and stuff.
Actually it was light enough for the camera to autofocus on the moon initially, so I got it to do that, then flipped the lens to manual.
I took a whole range of exposures and zoom levels over the next 1/2 an hour or so at intervals, and sorted through them to pick out the ones I liked.

Showing it in relation to everything else, and then a closeup of venus

which isn't very photogenic. I couldn't be bothered to set up the telescope and imager, as due to its location it means dragging the whole lot upstaris and onto the balcony, where the neighbours give me strange looks, and also the pizza was calling!

Another venus

Another go at venus. Well it was sitting there in the almost daylight allowing much easier telescope setup, so I thought I'd have a quick go. By the time it was all set and focused, it was pretty dark, and I got a few shots before is sank below next doors roof. This is probably the best of them.

Venus and Jupiter

I missed the transition of the moon and Venus recently - clouds and, well I forgot/had to ferry the children around at the time I could have seen it. Anyway, last night I did see Venus and Jupiter although they had moved away from the moon. However this called for some quick photography as they started to set behind the opposite house roof and getting set up in time always takes longer when you are in a hurry - plugs just won't fit into holes, especially in the dark. So I expect the focusing isn't as good as it could be.


Shows up the street light glow rather well dontcha think?

A bit of a mix

Going home last night I spotted Jupiter on the horizon from the bypass. Not that unusual its been there for a while, but wait, there is a companion with it today - Venus.
I rushed home and got out the camera, but the position was not very good - both were sinking fast and there was a number of things in the way. In the end the only way I could get them both in the frame was to straddle a tree!


As the sky was very clear, I had a go at a couple of other items too - the pleiades again.

I also tried M42 but haven't finished processing that one yet.

Deep sky

After buying some more stuff (mostly batteries and USB leads - so relatively cheap) I had another go at some deep sky stuff. I've never really seen the andromeda galaxy, but tonight I did see it, and photographed it too! However the photographs will need some work I think, but here are some preliminary pictures.

This one shows it rather overenhanced, but you can also see the small galaxy just above it.

Jupiter again

Jupiter is starting to get higher in the sky, but the conditions have been dreadful for a long time now. When it hasn't been raining its been threatening rain. All this adds up to lots of cloud cover.
Anyway, last night - just for a while, some of the sky was visible. There was still scattered cloud around, but less than normal and I could see Jupiter shining out - still not that much above the horizon.
I could also see that a couple of houses away, they had some sort of light show going on in their garden, as their tree's were backlit - hmmm!
Anyway - I had a go, the telescope aligned and settled on Jupiter very nicely. With the LPI I took some images and got some reasonable results.


With a bit of enhancement you can see some of the satellites too.

From left to right, Ganymede, Io and Europa on the right.

Then I got it to find Andromeda, nope - nothing, far too hazy and messy in that direction.

Jupiter in the round

A quick look outside and its a clear night. I can't be bothered to set up the telescope, but I take a look through binoculars at Jupiter, which is looking quite clear. As I watch, I see the ISS go overhead!

Anyway, I decide its worth a photograph, so I get out the camera and tripod and take a few snaps at various settings to see what I can get. Its nothing like what you see in the telescope, but it makes for a nice assemblage.

If you zoom in, you can see the motion blur dragging the points out into streaks, and this is only a 10s exposure, but from a distance it looks pretty ok. Zoom in not quite so far and you can see some of the satellites.

Jupiter - another go

I had another shot at Jupiter last night. With the telescope on the patio, I have a window of about 15-20 minutes when it is visible between two trees. This time I got set up a little earlier and managed two separate imaging samples. The visibility wasn't that great with it low on the horizon, and again it didn't look as good through the LPI webcam as through the lens. I guess the old mark one eyeball still has a useful range and pixel density.
You can see three of the satellites however, so that's a little better.

Also this time I had the settings right so I could post process the images with registax, which I think does a better job than envisage.


I might try a different technique if I get a chance.

Jupiter

Its been a while - but now the nights are getting a little earlier and I can be bothered to stay up. Also there is a new jewel in the sky, in the shape of Jupiter, so its time to have a go and see what can be got.
Its not easy, Jupiter is low in the sky between some trees, and after a few goes, the only place I can get a good view of it is from in the middle of a wooden bridge. This is not ideal, as everytime I move, the image leaps around. Even so, its the first go and the images are okish, but would be better if I'd saved them in a better format.





Maybe another night I'll have a better go, and remember a few more things. You can see a couple of moons, but its not as clear as it is through the eyepiece.

The moon and mercury

Its been a while since I took any photos of the night sky. What with some foul weather, and a dose of flu that had me confined to bed for a week, the opportunities have been thin on the ground. However tonight it was clearish, although some hazy cloud around, and I wondered about looking for some M object or other to try and photograph. However checking with a few star charts, and with stellarium, it seems Mercury might be visible soon after sunset.
Its in the west obviously, which is not a good view from our garden. A whacking big house being in the way for one! However we have a balcony on the front of the house that we never use, which I thought might be useful. It turns out to be an excellent platform for this. Being on the first floor, its not too far being at roof top level, or at least looking over the houses across the street is only 1 or 2 degrees from horizontal.

Anyway, I scanned the sky anxiously as the Sun set. Stellarium showed the moon would be lined up with Mercury, but such a thin wedge that it might not be visible. Eventually after much scanning, and not a little ridicule from the neighbours, I spotted a thin rim of the moon.
About 30 minutes later, as it got darker, there was Mercury - right where it should be!

Saturn again

Last night, I spent a long time trying images of Saturn. I've got a new motorised focuser, which finally means I can focus in an out with out any perceptible shake of the image. This makes it a little easier getting an image into focuser, although its still a lot of trial and error.

This is the best of the pictures from last night.

An iridium flare

Last night was a great night for observing orbital things, in theory. The space shuttle, a number of rocket bits and pieces and various other satellites were all scheduled to pass overhead.
However, that was the theory. In practice there was an awful lot of cloud about. None of that wispy mostly transparent stuff. No, this was thick piled up stuff as dense as you like. But - it wasn't wall to wall, at least not all the time.
Anyway - I went out to try and spot the ISS - although it was a bright pass, the time was not good, as the sky was still a faint bluey colour, the sun not having set very long ago. I could see a couple of the brighter stars after a while and the ISS should be magnitude -1.8 which is brighter than pretty much anything else in the sky other than the moon, but it wasn't looking good for the 3rd magnitude rocket bit that was coming over at the same time. I managed to spot the ISS eventually, but it wasn't the bright object it normally was.

I skipped most of the other passes as they were not very bright and with the large covering of cloud, would be difficult to spot. However there was an iridium flare scheduled for about 5 minutes to 10. The iridium satellites are a whole group of orbiting communication satellites, that have a highly polished panel attached, that if it happens to be in just the right orientation reflects the sun very brightly. There are programs to predict these events, I used the heavens above site.
I set up my point-and-shoot digital camera on video mode on a tripod pointing roughly in the right direction to try and spot it. I waited until about the right time, and then pressed the button and hoped that it was pointing about right, and that nasty bank of cloud would not obscure it.

What do you know, I saw it and caught it too!


It looks better at the original resolution, but you can see a bright dot at least. It is magnitude -7 or so, which is very bright indeed.

ISS and ATV

The ISS is being serviced by the ATV at the moment. They are in about the same orbit, but the ATV is just a little ahead of the ISS. The ISS is very visible at magnitude -2 or better, and the ATV is noticeable as it is leading the ISS. This particular ATV is the Jules Verne and is testing out various things.

Anyway, it was clear last night, but there was high level cloud which made everything a bit fuzzy, and the photos didn't show very much.

Tonight it was a much crisper night, and I tried taking the camera off manual and letting it take different length exposures based on the available light. They varied from about 5 seconds to 10 or 12. One of them actually caught both vehicles and showed them up quite nicely after a bit of rebalancing of levels. You can see the ISS as the main streak, and just to the top of the frame there is a thin streak from the ATV.

Also evident was about 3/4 of the way across the sky it went into shadow and started to fade, which is caught in the last one.

Another go at Saturn

I thought it was time to switch back from the DSLR to the LPI CCD camera and have another go at planetary imaging. After tea I had a look outside, and had noted the relatively clear skies throughout the day so thought it worth a go.

Having got the equipment outside, and selected polar alignment, I watched as polaris, and actually nearly the whole sky began to cloud over. By the time I was ready to try aligning there were no stars left to align on! So I went in and watched some TV and had a cup of coffee. An episode of Torchwood later, and the sky had cleared nicely.

I hooked up the LPI and the laptop, and tried Mars to begin with. A couple of attempts but it wasn't really showing up as more than a slightly orange blob.

So I switched to Saturn, which is now much higher in the sky. After a bit of fiddling around, and attempting to use the LPI to both image and guide, and a couple of software lockups, I succeeded in getting something.



Not too bad, in fact it was looking good enough that I thought it would withstand a bit more magnification. So I went inside and got a 2x barlow lens and slotted it in.
It was definitely larger, but focusing was really difficult.

After a bit more fiddling around, and using registax on the results and a bit of tweaking this is sort of the final version, even showing a moon.


This has to be the best Saturn image I have to date, which is nice!

Constellations

It was very windy last night, so I didn't try any telescope shots. There was a lot of broken cloud about and it kept obscuring different parts of the sky. However with the camera on a tripod hooked up to the laptop I thought it worth a few shots. With it fully wired up, once you are focused and aligned you can just leave it to get on with 25 shots of 25 seconds and go into the warm.

I started with the plough, as it is nicely aligned and easy to see. Had a go at Saturn in Leo, but clouds and aircraft conspired to wreck that.

Cassiopeia looked reasonable so I took quite a few of that and stacked them. I need to get better at post processing though.

Another go at the orion nebula

I tried some rather short exposure settings on M42, but decided this time to try some 25s exposures with the DSLR mounted at prime focus on the telescope. I wasn't sure that the telescope would track well enough. Also Orion is just above the house and descends below it through the night, so not an ideal location either. Anyway - worth a try.

It turned out that many of the images had elliptical stars, or were smeared out, but there were a number within the 25 taken that looked ok.

I used DSLRshutter program to take them which worked pretty well. I also experimented with nebulosity for focussing without much success.

Anyway - after throwing lights, flats, darks and biases at deep sky stacker, it pronounced that only one of the images was worth stacking... its probably right but it could have broken the news gently!

Anyway, its probably my best shot of M42 to date, but still not much compared with anyone who's any good!



Step by step, its getting a bit better.

More equipment

I got a zoom lens for the DSLR, and tried a few shots of th night sky with that. The results were not bad. These were taken from a tripod rather than a telescope mount so you can't do long exposures of the stars start to streak. Setting high ISO numbers and short exposures is the compromise.

Here is the Orion nebula taken.


and here is the Pleiades taken similarly.



and one with the shorter lens of the plough again



Then a couple of days later I tried the camera connected to the telescope again. I had it equatorially mounted and it seemed a little smoother. A number of the photos came out streaky though, so it was a question of picking the best to stack. So here is the orion nebula (M42) again looking a little better.


Its starting to look better. I'm not sure about the focusing though, and I'm not sure they are as straight as they could be. However the success story has to be the remote release I bought that connects to the laptop and the Delphinius software that allows you to setup a shooting schedule and go inside for a coffee while it takes and downloads 20 shots or more.

The shuttle and the ISS

The shuttle docked with the ISS and made some passes overhead during reasonable seeing conditions. I managed to get some reasonable trails from this event, although really you wouldn't know what it was other than a bright spot. I didn't attempt to get a telescope on it, it was moving pretty fast, but did have a look with binoculars.
You can see it rising above a tree in this trail, although there is also a confusing contrail moving horizontally.

And here it is setting, going past Mars. Two images overlayed.
