    Default planetary viewing with Celestron C90?



    Hi,

    I am an absolute beginner. My interest is observing the planets mainly and getting nice views of the Moon. Nothing too ambitious. I inherited a C90 and am rewarded by spectacular views of the Moon and the most interesting thing I have ever seen through optics of my own (non terrestrial that is), a shot of Jupiter and a couple of its moons. Jupiter's disk was small and gray, but very distinctly an other world with yet other worlds orbiting it. I am now hooked!

    But I wonder if I should upgrade to see more wonders. My urges say "yes!" but I want to proceed with caution. I like the retro orange styling of my c90 and lust after a c8 of similar time period. but I would really rather squeeze what I can out of the c90 before moving up and on.

    questions, for those generous enough to answer:

    -are there ways to enhance the c90? Are tele-extenders worth it? What about a barlow lens? anything else I should be aware of?

    -can someone recommend a decent tripod for this model? I have the motor mount but no tripod. I'd like something useful for star gazing but not over the top. Old models are fine with me.

    -what is the next step up? I see the fine pics taken with c8s which get me pretty excited about it. Frankly, though, I'm mostly interested in getting into the best good planetary viewer I can afford- $400-500 is approximate. I could spend a bit more but the turnip would start to feel very anemic much beyond that. (Not that it has any blood at all, but I'm sure you understand what I mean.)

    and I am practicing my naked eye observation skills. I think I am making some progress in that area. I don't quite see ice caps on Mars... or maybe I do...

    tell you what, I explored the thread tools and I'm finding answers on my own.

    Although I really would like a tripod recommendation, something that can accomodate the mount. Please, anyone? This one is bugging me the most and I can't find ANY information about it.

    Hi zandar,

    Welcome to Astronomy Forum.
    As my telescope does not require a tripod I cannot recommend one that will be good for your telescope. However I do know that a good tripod will cost more than $100. Others will be along to answer your question.

    Hi Zandar

    Welcome to the forum!

    The C90 is a Mak? Can you describe better what the "Motor Mount" you have is. The only versions of the C90 that I am familiar with fit camera type tripods. Are there any model numbers or such on the mount itself eg CG3 or somthing like that?

    Maybe "motor mount" is the wrong term. It is an electric device though.

    This might help:

    ... Never mind. I'm not allowed to post links yet. I have some pics of the scope and mount uploaded to ImageShack.

    Is there a way to upload images into a message? I don't see that option.

    Yeah upload into Astronomy Photos on this site and I will approve them, or PM the image shack links to me and I'll insert them here for you.
