During the last few days there were really promising clear nights. I recorded several data sets from my urban location (under these conditions, going up the mountains would have been a treat!). Now, as there are clouds again, I am processing the captured data. Here is the first result from the Leo Triplet (M65, M66 and NGC 3628).
I still have not yet received my color filters. So here I have a combination of luminance (UV-IR-Cut), H-alpha and O-iii data.
