I nearly did mono 'yrs ago now' but Im not that dedicated, speshly with incorporating and learning capture, software, calibration frames, processing progs and the rest of it, too much for this OSC One-Shot-Color duck , soo, much credit due your way for that alone 
Focus can change during the night, with temperature, between filters apparently, glass, filter quality, the list goes on,,
More data very much helps with signal to noise, meaning very much aids in capturing more 'fainter' details, but not necessarily create finer or sharper details, just thought Id point that
Oh, the Eagle on the agenda hey, Noice choice and am sure you'll do a great job with it too,, ,, |
Thanks for your comments Bob- yes, I agree that the image is leaning on the red side a bit/ was hard to mitigate to be honest. One thing I can say is that given it was my first go at this imaging I have learnt a lot. I should pay attention to applying 3:1:1:1: ratio for exposures to start with and also saw how much effort it takes to collect the data given I am using a filter drawer - focussing is super important and I noticed that the blue filter revealed rather bloated stars - I may need to peg back on the gain slightly for that color filter as it did play havoc with the stars during the combine.
I’ve been keen to move into mono imaging for some time and although it’s taken me twenty years I’m happy to accept the challenge. Imaging in the burbs has its difficulties and mono imaging with a cooled camera has already proven to eliminate noisy subs with higher res. I’ll look to perhaps bin2x2 during capture as a test after learning about image scale factors.
Pleeenty to digest but I love astronomy so that helps hehehe…

I was going to go mono myself but got stuffed around by the supplier, spent the money on a full frame DSLR instead and bought a used beginner model OSC which I don't get conditions or health to use much anyway so I'm glad I bought the usable full frame camera.

Thankyou Leo/ it turned out decent enough and glad you liked this shot of the Sombrero. You know what Leo- the beauty of the OSC is that you get a complete image with minimal sweat- the full frame camera must be a joy to use and having such a large window to show off the cosmos in all its glory makes for the ultimate space shot I recon.
