ISS this morning on an 87 degree pass. Tracked with an 8" LX200 at f/20 using Satellite Tracker by Brent Boshart. 1/250th second exposure with a modified Samsung SDC-435.

Here is a 'through the eyepiece' view of Jupiter from yesterday:

I need to work on getting more frames in my videos, but it still shows some nice detail.

What video resolution can your camera record, George? I'll try it with my camera next week, wich can get 640 x 480 for 32 minutes if the SD card is empty, but I'd like to know what level of detail it could be.

It is recording at HD 1280X720 for these pictures. I think in this situation it may be best to use a lower resolution though, because it will let you get more frames in, which means that Registax will probably produce a sharper overall image. HD is certainly not necessary - when most of the frame is dark, it does not make much of a difference. These photos were from 15 seconds of video at this resolution, so 32 minutes is fine. Give it a go!

A night with bad seeing and 10 minutes of video/18000 frames:

I'd say the black part right below the equator is the shadow of Io.

Here's comet Hartley 2 and the Double Cluster in Perseus, taken yesterday about 3 hours apart.
A friend has made a drive for my barn door tracker and i could doo these photos before the battery died in the cold. Still room for improvement with the periodic error.
First one is 15 stacked the other is 10;
60s ISO 200 F/3.3 12x zoom

Nice pictures. I still have to find Hartley 2. Last time I tried it was at Mag. 6 and I used Alpha Cassiopeiae as an aid (wich I also was unable to find, still have many things to learn). On October 17th, 17:53 GMT Hartley 2 will have exactly the same declination as Capella, so it could be easier.

Hi everyone,

I was inspired to make a little video which basically involves me talking about some of the photos I have taken - not much, but I enjoyed making it:

Thanks for watching.

Try to find it faster, the moon might make it harder by then.
You can try to print or draw starmaps off stellarium or calsky.com

I got an amazing hazy, filtered sunset this evening, and the Sun passed right behind the column of a power station - the distortions make the Sun look as if it is being sucked into the chimney:

Here are a few pictures of tonight's Jupiter/Moon conjunction, plus a timelapse:

I love it when they pass by together like that - this is the third time I have seen them in conjunction lately.

This is a long-exposure picture of the Moonlight reflecting from the stones on the drive - almost as if they were water. I also like how the trees are blurred where they were swaying in the wind:

My latest image, M45, shot at 200mm (Sigma 55-200, f/5.6) with my EOS400D mounted on my EQ6, exposure times were 20s, 1min, 5min, 10min, 20min:

And this is an older image I made in March or May this year, NGC7000 with the same cam, but a 19€ lens (135mm, f3,5, Berolina-Westanar):

And this is a 24h timelapse I made when the Eyjafjallajökull erupted, 24h of no planes, the only other Objects were the ISS and a Spaceshuttle.

I've build a new barn door tracker, with a longer arm (2rpm screw) and other improvements to elminate periodic error, and here's the result:
7x60s Iso 200, F3.3 12x zoom Panasonic DMC-FZ8 camera

This evening will hopefully yield some nice stargazing, but during the day, I got some photos of the Sun and its lovely atmospheric effects. The first is a display of crepuscular rays - it was very nice to wake up to. The others were taken during sunset this evening, and show some nice orange skies and landscapes set against them.

Very impressive stuff, Mattberg. I guess Iceland doesn't have much air pollution, unlike here. I want to do a night sky time-lapse but I'm not sure if I can, maybe if I can set my camera to take very long exposures periodically would help.

Another afocal Jupiter I got last night, with Europa's shadow eclipsing the surface:

Thanks George, you've posted some nice pics here along with everyone else. Been enjoying them, even your shots through the eye piece are better than anything I've tried with my scope!

Thanks for the appreciation - my attempts were pretty poor too, until I learned to stack video frames with Registax.

Just gave a shot a photographing stars:


ISO 160, F/8.0
645 second exposures on the Canon Powershot S90 using CHDK.


13/12 Edit: Many of the stars I photographed appear blue oddly:

EDIT2: Originals (which I have to edit significantly due to light pollution and smog) for those interested:
