Thank you Rob,
You have reminded me that I could regularly split beta Musca with my Astro-Physics 130EDT always before midnight and the scope outside for less than 1/2 hour. The 18" has yet to split this double as I don't spend enough time outside for it to cool/settle down enough!
Plus with either scope I rarely use more than 230x. Most commonly with the AP it was 7mm nagler yielding 147x Now I use either a 9, 13, or 17.3 in the 18" yielding 228x, 158x or 118x.
I sold the AP in September. The 18" is great for faint diffuse objects, but cannot match the AP on even doubles as yet.
