    Default What's in Your guide scope?



    Hello. I've looked at the Celestron guide scope package that will fit my scope (seems heavy?) and some on the Orion site (will they fit without having to adapt?). But before I make a purchase, I would like to hear more options from people with experience. Also wondering if any reasonably priced 50-80 mm refractor will do. I figure I'll be spending $200-$300, but should I just wait and get a better one? Feel free to comment & suggest. Pics of your setup are also welcome.

    Thanks.
    Jon

    Depends what you want to use it for - if it's purely as a guide scope, then anything with a reasonable focal length should do (I think the little finder style guiders are too short for SCTs) - on the other hand, if you also want to use it for wide field imaging, then you might consider one of the 80mm APOs (which would be overkill purely as a guide scope).

    You could also look at off-axis guiders - not as convenient for picking guide stars, but (since it's using the same optics) handles any mirror shift.

    Jerry - thanks and yes, it will be primarily for guiding. I would love a good APO, but that will have to wait. I'll be sure to research off-axis guiders. I guess I didn't think about the mirror shift difference between the two, but that's why I started the thread, to hear about & learn things I don't know or could think of (or haven't read yet somewhere).Thanks again.

    Don't know if they're still available, but lumicon used to do something called an easy guider - it combined an off axis guider with a focal reducer (just saw one on eBay UK, which reminded me).

    Thanks Jerry. Just read an older review of it on CN, it was compared with a Celestron off-axis guider. He liked the Lumicon easy guider hands down over the Celestron. Just checking the Lumicon site, they still make systems for Newts & Refractors, but I don't see ones for SCT's listed on their site. I'll continue my research for a solution. I'm getting the idea that costs will be similar for the price range that I am in, so cost is a wash either way. Like anybody else, I just hope I find something that works the first time around, being a newb to imaging makes that tough to do since there is some much info on the net to sift thru.

    There are plent of us using the Orion Magnifient Mini...

    I have used it on my C9.25 Lonnie has used it on his 9.25 HD just fine. Even the spects which might be a bit conservative.. say a 9.25 with a FR is inside its advertised range.

    And it was prefect when I needed to Guide my AT65EDQ.. plugged right onto the finder bracket.. a larger set up would not done that.

    Usefully to know - I hadn't considered that a focal reducer would drop you down into the supported range . I'd been wondering whether to think about one of them when I work up to autoguiding my scope - I'd originally planned on using an off axis guider, but the little finder style scope looks interesting... How does the guide camera attach? (I'd probably just be looking at the scope, since I already have a suitable guide camera).

    I use the Orion Magnificent Mini package for my C6. Haven't had many clear nights to really test it out to much. but from when I have used it it worked pretty good. It is good for up to a fl of 1500.
    This is my setup.

    Jerry, here's a pic of my set up with the Orion 50 mini. The bracket replaces the vixen style one, or could possibly even go in your current finder bracket. There are 3 screws that hold the camera in place.

    Thanks to both of you for the pics - that looks like a definite possibility for the future - I think I should be able to put something together that would let me connect one of those to my scope, and it looks fairly straightforward hooking the camera up
