Grazie Fabio

If you don't lose any resolution as in the two systems described could be a worth going for longer FL at 2x2.

Well, you could have something there Lucas but sounds like a maybe in theory but perhaps not too obvious under normal conditions..?

My thought experiment was just to throw it out there for others to think about it, as lots of imagers just kinda follow what seems to be said around the traps without really understanding if the logic is even valid and can think they must need a certain configuration...but for no good reason

To make it even more interesting... here's another one to ponder:

Is it better to extend a short FL fast system or reduce a long FL slow one...aaah??

Hmm? perhaps should have posted this thread in a thread, in the astroimaging discussions area

Also, a reminder of why I don't do RGB. RGB images are really hard to get right! When done as well as this one they are beautiful indeed, and it's real craftsmanship that's on show here.

PS: As has been mentioned already - I too love all the little galaxies on parade here.
Hmmm, I am a little confused by your post Andy ..do I read between the lines that you like this image

Thanks mate, nice to hear
