Way more help than needed:Celestron 9.25 SCTPosted By Gerald Dunn |
William Wrote "The reasoning given was that I needed bigger aperture than 9.25" to support higher magnification to combat light pollution for observing DSO.
Perhaps this forum has a different opinion?"
William- Aperture wins every time. Now using it to combat light pollution is an interesting view point. If the optics are equal in quality then "they" are correct. Now, I once owned a C-11, and my gosh did it have nice views. A strange thing happened, I brought it out about a dozens in the first three months, but after the excitement of a new scope wore off it only came out a dozen times in nine months.
Then I decided I needed a second scope to be more portable and cool faster than my C-11. So I bought a TV 101, didn’t like it. Then I bought a TAK 102,loved it but wanted more aperture. The Celestron 6” refractor seemed in order. Nice scope, but way too much purple. That steered me to the AP F/6 5”. What a great scope. Mars was out then and I loved the views it put up of the red planet.
I decided, after many more trips out into the back yard with the AP than with the C-11 that it was time for the C-11 to go. And so I sold it. Spent the rest of the summer with just one scope and thought I would never need another scope.
Well I went to a star party and started looking through the larger scopes and I was getting aperture fever all over again. Decided a C-8 would do the trick (when I started in the hobby some years before, this was my first scope). I got a great sample from a nice guy in North Carolina off of Astro-mart.
I told my wife I had two scopes that served different purposes and I would never need to get another one. I was set. That was until one night I decided to do a shot out with the two scopes on the planets (Jupiter and Saturn). SCT won; no, let’s say a draw. I had two scopes with equal views but one cost 1/12 as much as the other one. To me it seemed a no brainier. I sold the AP here on Astro-mart in two hours for as much as I paid for it.
Life moved along; me and my C-8, as happy as two bugs in a rug, but I made the mistake of buying Binos. Now I wanted more light and that necessitated more aperture, but I had learned my lesson and I wasn’t going to get sucked in again. This time I went to star parties with my Binos in hand and started asking people if I could use them on their scopes. Everyone accommodated me and I was able to settle on the 9.25.
This scope really is the perfect middle of the road scope; not too big, not too small, great views of the planets and great views of DSO’s. Mounted on a GM-8 it is perfect for visual work. How does it rate against the big dobs; well I never owned one because they looked like way too much trouble and are just too darn big. Now does this answer your question; I doubt it, but I sure did enjoy telling my scope buying tales.
