    Default Next scope, Celestron Advanced VX 6 Refractor Telescope?



    Hi all,
    Looking for some suggestions.
    I want to get a new scope and a new mount to add to my collection.

    The Celestron Advanced VX 6 is a 6" 150mm and F/8.0 scope is on my radar. ($1,250) It's an upgrade over my Astroview 120mm 5" refractor.

    The mount included is an Advanced VX GoTo mount which I can add an auto aligner separately. I would prefer that because I'm not going to be viewing from the same location as I live in an apartment in NYC now and will travel to a less light polluted site for photography.

    My sole purpose for purchasing this is for Astrophotography.

    Now if anyone is familiar with this set up I have some questions.

    Its comes as 1.25" so I assume the focuser isn't a 2" with the 1.25" adapter. My question is, the telescope able to be upgraded to 2" focuser?

    Also, the auto aligner, are they worth the money if I'm not going to be in the same location?
    Where could I find a case for the optical tube? It's 51" and I couldn't find a case specifically for this telescope.

    Any feedback on this telescope is welcomed.

    -Nico

    Hi Nico!

    This scope comes with a 2" rack & pinion focuser, a standard Synta affair.

    It is a rather large scope. I would suggest that it is not especially suitable for imaging purposes. Being large, you will be pushing the mount for AP. For visual use, it will be outstanding.

    It is also an achromatic, so CA will be an issue for AP, though it is well controlled for visual use.

    The whole setup, mount and scope, weighs about 90 lbs. You'll be moving mount/tripod, then two 12 lb counterweights, and then a 20 lb. OTA. Lots of trips.

    The AVX with a smaller APO would be a much better setup for AP.

    The alignment routine with the AVX is quite easy and takes less than 10 minutes to accomplish. The all-star polar align routine is even faster. Not sure that an auto-align mechanism would be especially feasible to purchase if you already have a reasonable familiarization of the sky.

    Oh, did I mention it's big?

    You do realize that it is a achromatic refractor and not the best for AP?
    The telescope has a 2" focuser already but it is a poor one and definitely benefits from an upgrade.
    I use a Plano hard sided golf club case to store/ transport my scope and mount. The AVX will fit in a case on its own also.
    This is a heavy setup, with mount, counterweights and telescope it is right around 90lbs+ without adding in any other cases, power pack, etc.

    Wow. That scope is huge! I actually want a scope that size eventually. Thank you both for the info. Perhaps I should just get a goto mount and use my Astroview for AP.

    The VX mount has been identified as being OK for astrophotograph but the scope is not ideal. I would suggest a 100mm triplet or semi-APO as a better choice for an imaging scope on the AVX mount.

    Hi,

    The AVX mount payload capacity is 30lbs. For AP you want to keep the payload to 50-60% of the mounts max payload. So your AP payload amount should be somewhere between 15 - 18 lbs. This does not include mount counterweights. The 6" reflector that comes with that mount in one of the Celestron package deals is OK but not really best suited for AP. The achromat you're speaking of is as close to completely wrong as you can get for the AVX mount for AP.

    Your best bet with that mount is a nice smallish 80mm APO triplet refractor. This OTA is small enough for the mount to easily handle. It is also very forgiving because it is easy to guide allowing you to take amazing images. After you have this setup down pat then you can think about moving on to a larger (read more expensive) mount and OTA. Remember everything and I mean everything revolves around the mount and its payload capacity.

    I hope you take this advice seriously. I know from what I speak. I started with an 11" f/10 SCT as my primary imager. The number of headaches it produced where enumerable. When I got my AVX with an Explore Scientific 80mm f/6 APO triplet, AP got so much easier.

    Cheers,
    JT

    PS. easier is a relative thing. AP is by far, the most unforgiving, technologically involved, artistic endeavor on which I have embarked -- even using an 80mm scope.
