I didn't check but would guess right about one hour. Plus ~30min registration. Normally I just start the process and leave my laptop and come back later, so I don't know for sure.

Absolutely stunning image! Thanks for sharing
Also we were quite surprised how bright the nebula is. We didn't thought to get that much signal with 15min exposure time. Even more so as our camera is not infrared modified.
Interesting, how much power does the laser have to need to be able to burn the paint?
Haha, the board won‘t win any prices for sure. But for a first try I‘m still very happy.
Sure thing :)
Yes exactly. It checks the weather forecast however so it doesn’t water when it‘s raining. This way I don’t have to refill the canister too often. A better way would be to attach moisture sensors to the plants, but I don’t like having to change batteries constantly. This is a very simple solution but it works for me.
I just printed the design on a glossy paper and used an iron to transfer the toner from the paper onto the pcb (last image). The toner protects the underlying copper in the etching process, so only the free copper gets etched away. I used Na2S2O8 for etching.
Yes UV is so much nicer, I also use this method now when I‘m not ordering online.
Ah ok, so I assumed you registered all your light frames onto your stars as your stars look very sharp. And that’s the normal way for every astro image you would normally do. A comet however moves so fast that its position changes even in the short time frame were you took the images.
So after registering all the images with the stars pattern you want to make a second registration were you mark the position of the comet on the first frame and on the last frame. With that now all images are aligned onto the comet and now the stars appear to move in the background. As your stars look so sharp I assumed you didn’t make the second registration. In DSS there is a comet mode for that but I haven’t worked with that so I can’t tell you about the workflow with that program.
Hope that helped in any way!
Ich gehöre seit heute auch dazu. War ein langer Kampf, letztendlich hat alleinig die Gesetzesänderung zur Durchsetzung geführt.
