This was my first real attempt at Deepsky imaging last year. Just Ha as I hadn't worked out how to combine other channels yet. Made possible by driving the 10 miles to FLO and handing them my open wallet a month or so before!! Being Devon, it took about 6 weeks for the cloud to go. Its the handily named SH2-108 Nebula.

I use a hot air gun and solder paste for my smd components.

Wow !! - I'm still waiting for some clear nights to get my first DSO after 20 years away from the hobby. I hope it is half as good as yours!

Welcome from a neighbor in Devon.

I was watching this AstroBackyard tutorial last night (trying to soak up as much info before I begin my baby steps in astrophotography). Trevor, at one point, goes into removing halos. https://youtu.be/5GgruZ-1zQ0. I think just after halfway.

I would have thought a local Astronomical Society would take them, assuming they have the storage facilities?

Currently away from home and haven't applied any flats to the image. The processed image above was not from the FITS files but from the jpg. I need to install a FITS application but as I'm connecting my laptop via my mobile I'll wait until late tonight when I get home. Maybe the lines will go away. Not too worried myself but it would be good if they could investigate the issue. I'm using the course as a v.small taster of doing a longer AstroPhysics course. i.e. can I find the time to study. Maybe the PGDip Astronomy from York.

It is, which is why I moved "back home" a few year ago

Hopefully I'll be able to take one with my own telescope this weekend although South Devon isn't particularly known for clear skies.

My first image in about 20 years! Taken with the Open University 14" SCT (COAST) on Tenerife last night. A single 120sec frame, BVR filter. A little bit fiddling of light levels by me (total novice here). I'm running thru the short FREE 8 week course "Astronomy with an online telescope"

Just found this thread having been reading up on 1420MHz Hydrogen line imaging (I'm a radio amateur and professional software developer). Great amount of info here...many thanks to everyone I have noticed that some people are adding Satellite boosters after the pre-amp? Normally the pre-amp should provide enough gain to overcome any feeder losses down to the receiver and also alleviate receiver sensitivity issues, so I'm not sure why they are required? Also the boosters seem to be 75ohm which means a mismatch and consequent signal loss unless there is some matching being implemented? I'm sure there is a good reason just can't understand it at the moment. A lot of good work going into this though. I'm looking into doing the same but extending to 2 dishes with interferometry, although finding a location for them (I'm in South Devon) may be problematic (back garden, I've been strongly informed, isn't appropriate.....).
