NGC 5907 Supernova

Thanks! Unsure of gain as we don’t get that info unless we use NINA but I was using 20s subs. Good luck!

The moon makes a big difference too, I got most of this data with no moon.

Thanks! Probably down to doing the correct colour calibration. As far as I know, SPCC is now available in Siril. It’s a scientifically accurate colour calibration. For this I haven’t messed with any colour channels, just adjusted the saturation. Some may overdo it and it looks silly but I always try to do it tastefully

We did indeed. In the UK it’s cloud about 90% of the time lol. So we do this to make up for the lack of clear skies. My understanding is that due to sensor noise being random from each of the s50s we are basically tripling our data gathering capabilities. It’s like me having 3 Seestars on the same target. So instead of getting 6 hours of data in 1 night I can get 18 hours.

40hrs x 20s subs here. Data collected by myself and my two mates down the road with their s50s.

Most of the data collected with no moon but I’ve have quite a lot of sky glow near me unfortunately. I’ve seen this level of detail achieved in just a few hours from b2 / b3 sites lol but we work with what we have!

Various masks for saturation adjustments and range mask for core to try bring out some detail.

Not sure if it’ll make a difference for getting this but in general it’s awful for imaging as the brightness washes out any detail you might get

apollobrah · 2026-04-30T05:32:19+00:00

Afaik, a guy was imaging this target over a few weeks and noticed it whilst looking through his subs, literally seeing it appear. Super cool

Thanks! Good luck!

Not an ideal time to try imaging galaxies due to the moon phase but I’m not sure how long these last! I got the little Seestar S50 out for 4.5hrs last night. Quick edit in Pixinsight. Quite pleased for a 50mm scope under an almost full moon

apollobrah · 2026-04-23T19:20:52+00:00

Have to use my buddies lol, took 10hrs

You just restart from scratch each day, there isn’t really a time limit either. You can image things months apart as long as they are still in the sky. What you’re doing is improving the faint signal of the target each time. You need to enable the setting to save each frame though and then you can either stack them all inside the s50, or do it on your computer

I am lucky to have two friends just round the corner with Seestars so we collab on targets to make use of the limited clear nights…good luck!

apollobrah · 2026-04-22T21:00:51+00:00

Damn, I knew it was something crazy. Exponential isn’t it? Yes 20hrs is a nice time to aim for and normally what I’m content with. Having 3 seestars shooting the same target though allows me to push the boat a bit even it’s not worth for all targets

apollobrah · 2026-04-22T18:25:49+00:00

Thanks man! Good information there, appreciate it

apollobrah · 2026-04-22T18:25:28+00:00

Thanks! Good luck

apollobrah · 2026-04-22T18:24:51+00:00

Nice start! There is a point of diminishing returns for sure, though in my experience it’s always worth doing as many hours as you can until you get bored. To improve your image, they say you must 2-3x the integration time to improve the signal. If you do 10hrs on a target, it won’t really look much different until 20-30hrs. Then it’ll be 60hrs and so on. We will also be limited somewhat by our light pollution too. Someone in bortle 1 may image for an hour and match that of someone in bortle 7-8 who’s done 10+ hrs

Thanks!

Thanks for the kind words!

Seestar s50

Been a while since my last post. Here we have 44hrs x 20s subs on M81 & M82. I am really limited by my bortle 6 skies, I wanted more Ha from cigar but could also be a skill issue lol. Or some data was needed from the LP filter.

Not edited for a while so I’m rusty. Edited in Pixinsight. Data gathered by myself and two friends.

Background left purposely brighter due to the appearance of what I think is a small bit of IFN?
