Hi Milton, 

I looked at  M 61 too though I think it`s smaller & fainter than M 66 from memory...? Here`s a combined LRGB filter simulation (photomerged in Photoshop) I did, with the Scorpion 20SO`s spectral details entered, at about 60 x 60 seconds per filter... so 4 hours of imaging..

Mark.

Glad you like them. Even with the Light Pollution Filter, my sky
background is 16,000 to 24,000 out of 65,535, so a lot of the faint
fuzzies and subtle details are lost in the background.

It's on my "to image" list, along with the bigger 3rd member of the
Leo Triplet, NGC 3628. I have to flip the OAG around to image both and
get a decent guide star. M61 is another nice one I want to capture and
has some interesting companion.

TTYL..
