Atik 450L vs 428EX

Intended use is with a 80mm APO at F5.6

Also might be used with a 250mm Newt F5 ish

I will have both Narrowband and LRGB filters available (1.25" my wallet cheers! ).

I like the size of the 450L but the 428EX is very sensitive.

Any thoughts?

I have a ATIK428Ex. I've used it w/ a C8 EdgeHD at F/25, F/10, F/5 & F3.3, a SkyWatcher 80ED at F/7.5 & F3.75, a Lunt 60DS solar scope direct & w/ 2.5x PowerMate, several camera lenses, etc. It works nicely with everything and the sensitivity is great!
