[...open cluster...] This will give you all the information you need, applicable to planets, stars, nebulae...

That's a grand idea. Do you have
single frames of short-ish exposure of it, captured through a newish achro or apo or both?
Might well be very useful!! Thank you!
However, I'm a noob. I can't tell anything from seeing an open cluster. My sole "experience" is a colored nebula - NGC3372, as I now know. I've captured/seen it with a 200mm lens and with my 8".
Well, and Orion - but only with the lens in pre-telescope times.
Now, I need to do something with my setup - which means spend money.
So, I'd like to see the difference in colorful big objects of achro and apo, 80mm and bigger. Maybe I can live with what I would get through an achro? That's what I want to try and find out.
And other noobs might be interested in planets and the moon and the sun and would appreciate a comparison in these objects before they spend all their money on an APO
