Struve’s Lost Nebula
This is a composite image using DSS2 data and my own Sky90 data of the Struve’s Lost Nebula region. If I ever get the skies, I will need to get a lot more data on this one.
A Carbon star in the Gamma Cass region
I was just looking at an old Gamma Cass image (for another reason) and saw a bright red dot for the first time. Yep, it was a Carbon star that had been there all the time and I hadn’t noticed. … Continue reading
M42 and the Running Man
After the CTB1 experiment – M42 was well-placed in the South and I managed to get 10 x 3-minute subs before the cloud rolled in from the West. This is pushing me to get 100 x 3-minute subs just to … Continue reading
My Nemesis – CTB1 – but with a ray of hope.
The faint red ring that you can hardly see in the centre of this image is supernova remnant CTB1 in Cassiopeia. I have tried imaging this one for years, and this is what I usually end up with. I thought … Continue reading
5th Order Menger Sponge
Here is a 5th order Menger sponge I made up from 20 4th order Menger sponges printed out on a 3D printer. A 30cm ruler is included for scale.
The Andromeda Galaxy, M31.
This is a composite image incorporating very recent Hyperstar 4 data with very old Sky90 data.
Another 7-minute ISS pass from earlier in the month.
Here’s another long 7-minute pass of the International Space Station from earlier this month (I’ve only just got around to processing the 17 frames of data). Annoyingly, as you can see, I didn’t continue long enough off the right hand … Continue reading
Space station pass tonight 5 p.m.
A nice long 7-minute pass of the space station tonight. It has been good all week with long passes – but it has also been mostly clouded out.
The California nebula processed from DSS2 data.
Yet another boring grey day with absolutely no chance of imaging. So to keep my hand in with the image processing I decided to have a go at the California nebula region using DSS2 data. I tell you how to … Continue reading
