Nix, Ok I understand another post like your others. Do you still have the ZR 7x36ED2 and do you like it?
So, my meager thread of 6.5X21 Papilio and ZR curiosity evolves into an affordable spotting scope that can be employed also as a backyard/deck observatory.
------deltahogfan,
I always caution those wanting to dip their toes into the world of telescopes that they won't be seeing anything like the pictures they find everywhere. Not even close. Those pix are made with HUGE apertures, long exposures, and often stacked images to enhance things even further. Most small scopes won't give you much at all. Sure craters on the moon, Pleiades, Orion's belt, Saturn's rings, the 4 largest moons of Jupiter, etc. but the later all very very small images with not much at all in the way of detail even with averted vision. The C90 in this context is a doable, inexpensive option that is better than cheap department store telescopes but again not in the class of higher quality refractors, reflectors, and compound scopes. It in no way comes close to my Intes-Micro Masutov-Newtonian (see thumbnail). So as long as your daughter understands all this she won't be disappointed and loose interest. Instead she will try to see the best that the small scope does provide and enjoy that. As an aside you might also take a look at a bit larger scope such as the C5 or Meade 125. They will be better as night time instruments but more cumbersome as spotters and also with a higher power lower magnification limit to deal with.
So..... now that we have your expectations throttled w-a-y back, lets look at the pluses and minuses of a small astro scope for spotting. The larger apertures indeed give you brighter high power images than you'll probably get with all but the best quality dedicated spotting scopes. Pressing the later with high power invariably gives dark views again in all but the best (read: expensive). BUT resolution with astro scopes in terrestrial mode also isn't in the same class unless you're talking high quality expensive tubes like those from Tele-Vue. But you will see bullet impacts at reasonable ranges (e.g 300m) and traces much further out with the C90. I really depends on what you want. For me it was a good move up from my decades old Korean Tasco 50mm spotter Certainly can't complain about the cost of the C90 at all. You get a LOT of bang for the buck in my view!
