Celestrion 925 cpc

[eyes]

Hi all,

Just realised I have to start a new thread, sorry.

I have recently purchased a second hand ,used 5 times Celestrion 925 CPC telescope and would like to know what sort of items I will be able to see clearly, as when I looked at the stars they still seemed very tiny dots.
will this scope be good for use with a SLR camera, and what else should I know that will be of use to a greenhorn like myself.
Love the site some excellent threads

Thanks.....Eyes

Small dots on stars is what you want! A telescope will never resolve a star so that is shows a disc, they are too far away.

You'll see everything that's out there 'clearly' - With the understanding that we are looking through atmosphere with a telescope, any disruption (like the jetstream, fog etc) may & will limit your success.

To get the best out of any telescope, you'll need to know how to collimate (line up the mirrors) as well.

9.5" ? nice you should see a lot of good stuff assuming:
its good 'seeing" conditions
your not in a built up area (or if you are it wont be quite as good but still fun)
its aligned correctly, dont try unless it you are happy doing it, maybe your local astro society can help and show you how, if it needs it!
any problems post them up someone will know. where you at? (countru ??)

Hi Eyes
There are a few issues in your question and I will answer the easiest first. The scope can be used for astrophotography but as it is mounted on an alt-az mount you will be limited to very short exposures. It is possible to mount it on a wedge and polar align it, but I wouldn't bother unless you are serious about entering the dark money pit that is astrophotography.
The other question is what can you expect to see. Stars will always be points, if they are not they are out of focus! They are simply so far away thats all you will ever see of them, what you can see with a scope of this size will also depend heavily on how much light pollutioon you have to deal with. If by countru as your location you mean you are in the country, then you are in luck. Hundreds of glubular clusters, open clusters, galaxies and planetray nebulae are within reach. themain planets will all be visible as discs, eg Mars, Jupiter, Saturn, Uranus and Neptune.
Does your scope have Go To and have you figured out how to align it yet? From memory I think they use a number of stars so you may have to learn positions of some brighter stars to assist with alignment.

Hi eyes.
I have a CPC11, previously had a C9.25. and I reckon you have made an excellent choice.

Both of my scopes held collimation really well so you probably need not worry about that.

Did you get the user manual with it?
Read that about set up and alignment and the scope should take you effortlessly to Nebular, Galaxies, and star clusters (not to mention planets).
If not, you can download from Celestron site as I recall.

If you are local (where are you?) we can arrange for you to come to an observing site and get all the information you require (wit or without your scope).

Above all, seek help, be it at an observing night, or astro book/atlas. Otherwise, if it becomes too hard alone, you may get frustrated and miss the opportunity to develop your interest in the great hobby.

We all started as you did, so we are all happy to share/help. Its part of the fun.
