Horsehead and flame nebulae

[Astro Noodles]

I spent 4 hours the other night and ended up with just 6 frames of 90 seconds. 😒 Using the WO 61 on an iOptron Skyguider pro. it is necessary to get the rig very precisely balanced. I think that the dew heater lead must have been snagged or something because I had star trailing in most of the subs, but not all of them !?!.

Anyway, because the frames were not closely aligned I decided to ditch the dark frames. So what I got was an image without much signal and without much noise. 😆

There is plenty of both signal and noise in that image - you just need to look at it from a distance

Perhaps by your standards, but I'm used to much more noise (most of it light pollution it must be said). 😁

Its a lovely image I would be proud of. As @vlaiv mentioned there is a fair bit of signal + noise I have cropped the image and used Siril to do a photometric calibration. Here is the output.

I agree @Astro Noodles!

I tried the Orion Nebula about a week a go, using my Sky Guider Pro and WO Z73, that was a nightmare. It struggles with objects low in the sky due to being both at the upper weight limit of imaging and not balanced well, I also spent about 2-3 hours out in the cold for 26 minutes of out of focus and drifted data, I know exactly how you feel mate
