I finally got my setup complete and started imaging. Since I'm doing this from the suburbs of the SF peninsula, light pollution is present but has to work for now.
- Mount Skywatcher EQ6R-Pro
- ExploreScientific ED127-100
- Now ASI1600mm-Pro with the 8x Zwo filter set
- Guide scope Astromania 60mm, guide cam Zwo Asi120mm-s and a dedicated RapsperrbyPi3+ for operating PHD2
I acquired 10x2min per channel for Ha, O3 and SII with gain 138 using SequenceGenerator at -20C camera temp, registered with Fitswork (and also tested registration with DeepSkyStacker) and did the false-color overlay with Photoshop.
I have a feeling that the image is still somewhat grainy - is that due to the gain setting I am using (unity is supposed to be at 139) or do I have collect more images (integrate for a longer time)? Is 2 min fine or would I run into issues with light pollution? Do you have any suggestions?
Sorry, I'm new, still learning... is there a better way of doing (the correctly registered) overlays?
Thanks for any input!
