Here's my version of M100. Captured on 16/04/21 with my 9.25 SCT, CGX, ASI294MC using CPWI, NINA and PHD2. 89 x 120 seconds at 180 gain, 10 darks, 30 flats, 30 flat darks. Stacked in DSS, Processed in PixInsight. My first nearly 3 hour exposure and one of my first PixInsight process jobs. Regards Graeme

Here's M57 from 19/05/20.This was one of the first deep sky images I had a go at a couple of years ago when I didn't have a guide scope and even less of a clue than I have now. So I thought I would give it another go.20 x 240 seconds at 800iso. Could have done more, the sky was clear as a bell. But it was a school night.10 x Darks. The first one was a mass of red because the sensor was sitting at 46C so I had to wait a while!20 x Bias20 x Flats at 1/25 second on Av. The histogram looked high but they turned out ok.CPWIStellarium APTPHD2 DSS GIMP

Was wondering the same too, now I have a guidescope set up and half a clue of how to use it! With the busy todo list of running everything else, (the Zoom talk was brilliant last night, thanks) could the task be delegated to a Moderator? Regards Graeme

Cheers Jeremy. Regards Graeme

Barred spiral galaxy NGC3953. Close to M109 and a similar size and brightness. We had yet another clear Kentish night sky so I had a go at capturing it. Celestron 9.25 SCT, CGX Canon 600D 20 x lights at 300 seconds 1600iso10 darks, 20 bias, 50 flats Regards Graeme

Hello I put a cardboard and duct tape flat frames light box together recently. After reading this very informative thread I can see that my effort is definately a mark 1. Foam board is the way to go! Regards Graeme

Thanks Carol, excellent images there. And when the video finished I spotted a link to your Levels and Curves video. Very useful. Some interesting use of Curves I've not seen before. Regards Graeme

China and Russia will have their own constellations, as will UK, ESA, Japan, India, Saudi etc. There will be 100s of 1000s of satellites up there! I've not been doing astrophotography long, probably won't be doing it for much longer!

Cheers. I was quite chuffed to get nice round stars at 300 seconds after all I read about differential flex with a guide scope on a 2350mm SCT. If we ever get another clear night I'm looking forward to seeing how far I can go. Regards Graeme

Conservation of angular momentum. As soon as the cloud of hydrogen and dust that forms the star start to move to contract due to gravity. Regards Graeme

Cheers, I've had the SCT/CGX for just over a year now so I've done lots of sub 60 seconds subs but this is my first 300 second attempt. The PHD Google Group folks were very helpful. Regards Graeme

Here's my first guided DSO. I got a guidescope for Christmas and after setting it up and having a few practice runs I decided to go for M42. Celestron 9.25 SCT, CGX Mount Canon 600D Celestron 80mm guidescope QHY5-11 Mono guide camera 12 x 300 second lights (then the clouds rolled in) 12 x darks, 50 x bias Aligned with CPWI Captured with APT Guided with PHD2 Stacked in DSS Processed in Gimp Not perfect but I'm quite pleased with it. Regards Graeme

Thanks for the reminder. Just firing up the iplayer now! Regards Graeme

Wow! I got a third and I've only just noticed! Sorry I've been away. Thank you very much. Regards Graeme
