I have had my eye on an Astro Tech AT111EDT (http://www.astronomics.com/main/product.asp/catalog_name/Astronomics/category_name/K56U1T2Q7KWF8GDVGLKVBN1PL3/product_id/AT111EDT) triplet refractor for a while and have recently come across the Explore Scientific ES102 (http://www.astronomics.com/main/product.asp/catalog_name/Astronomics/category_name/X7NGE9TGLGNG8MC3LRLTD7TDR7/product_id/ES102) triplet.
The explore scientific is on special for $1000 USD (usually $1399) and comes with rings, finder, diagonal etc.
The astro tech is $1595 USD + $100 for rings. It also has a pretty robust rotatable imaging focuser.
In either case I will want a field flattener too for imaging. Something like AT2FF for $150.
The main differences seem (to my very amateur knowledge) to be:
Aperture 111 vs 102
Glass, ohara vs hoya (not sure how different they are)
What do you think? :thanx:
