    Default Explore Scientific ED 102 APO with CG-5GT?



    It's been 15 years since I've had a telescope and am just getting back into it. First one was a cheapie Meade 60-ish mm refractor on a rickety alt-az mount. Nevertheless, it served me well by giving me the astronomy bug. I'm now considering an ED102 APO on a CG-5GT mount. Any thoughts on the compatibility of this combo? How does the ED102 attach to the CG5?

    I'm guessing it's sufficient mount for visual observation, which will be its primary use. What about for astrophotography? I already have a DSLR and would like to at least have some capability to dabble in AP in this setup. I'm sure a CGEM would be much better, but for the moment that's more than I want to spend.

    Thanks.

    Hi, Welcome to the Astronomy Fourm and back to astronomy.

    A ED102 APO on a CG-5GT mount ought to be well suited for both visual and photography work. The Celestron CG5 mount is solid and widly used for astrophotography. The CG5 mount has a Vixen Dove Tail saddle so you will need Vixen dove tail for mounting. Here is an example of one. Stellarvue TP10 - Vixen-style 7 7/8" Dovetail Rail - OPT Telescopes

    Hi coolie. My favorite combination is my Burgess 127 on my CG5GT. While not as rock solid as with my Orion Mak, it's very steady, so the combination you have chosen with the scope being significantly lighter should be very solid. As far as astrophotography goes, I have only recently tried a few photos, and the tracking was perfect over 30 seconds, and I would expect to be able to track a lot longer. My stars were slightly oval, but I believe that to be due to periodic error in the gear train. The mount also has a guide port.

    Thanks everyone for the welcome and the info. Now the big question is eyepieces. The ED102 doesn't come with any. I'd rather go with a couple higher quality ones instead of a huge collection of mediocre ones.

    The Naglers are new since I've been away and they sound intriguing. I'm thinking about a Televue 25 or 32mm Plossl for the low end, and a 7 or 9mm Nagler for the high end. I believe those ranges keep me in the 1.25" area so I don't have to jump over to 2" EPs. Is that correct? Do these seem like reasonable combinations for this set up? I live in the city and may only get out to dark viewing areas a few times a year, so viewing faint DSOs isn't as important as planetary and brighter Messiers etc.

    Thanks.

    That's good news DP. Thanks, that saves a fairly significant cost.

    Coolie,

    There is even more good news regarding explore scientific. As you probably know, ES
    has big savings until Mar.31st 2011. The es 102ed apo is on for $1300. USD.
    Ep's are also greatly reduced til then. Around here, a 82 degree afov, 7 or 9 mm T6 Nagler goes for about $300. ES has approx the same mm"s for $99.95 and they are
    waterproof and nitrogen-purged as well as 82degree. Most of the same bang for the
    buck but at 1/3rd the cost. Quality at affordable price - I am awaiting a 6.7 N2.
    Check out Oceanside Photo and Telescope (OPT).

    Good Luck,
    DP

    @Coolie, did you get the ES102 and CG-5 together? How did they pair up? The ES102 apo is on sale again and I'm going to try and grab one real SOON. I already have the CG-5GT but I've only used the DSLR itself on it and even that alone is nice.

    Visually, my ES AR102 is extremely steady on my CG4 mount and the CG-5GT is the next step up.

    As for eyepieces, my Meade 8-24mm zoom is excellent but if you look at my signature, you'll see I have a couple of ES eyepieces on order and both those lenses got great reviews

    Good luck!
