    Default Equatorial Wedges



    Hi everyone

    Hoping to get some advice... I have a Meade LX200 GPS scope and want to dabble in some astrophotography. I am considering getting an equatorial wedge in order to get some longer exposures but have heard various reviews that the Meade X-Wedge isn't the best... Are there other options or is a GEM the only way forward?

    Thanks!

    If you're wanting to "dabble" in DSO AP, are willing to do some experimentation and live with realistic limitations, and don't mind hours of frustration, then you can do some work with a wedge. NONE of them, including the Meade, is the best. The "BEST" way forward is the other option of the GEM, which I seriously, SERIOUSLY recommend over using a wedge.

    Thanks - I assumed that to be the case... For now I am also only imaging with a standard DSLR but am hoping to get a video camera soon and ultimately a CCD. Can you recommend a GEM that would function well with my 10" LX200 that will not break the bank?

    Other than possible camera clearance issues near the zenith, a wedge will work just fine. I suggest starting out that way. You will also need a counterweight rail to balance the OTA.

    I do not know what is available to you, but I would look for a mount that supports at least 50 lbs. Something in this range.

    It isnt that hard to make one. i have made one for my lx90 10", it works very well. I kept it simple, made it non adjustable. this could be a simpler quick solution so you can 'dabble' while finding a more permanent solution or while saving for a comercial unit. Second on the counter weight rail to balance scope, very important!
    Also, when using the wedge, it's better, with this particular scope, due to weight and awkwardness, to have it be a more permanent setup. Definitely easier to mount onto wedge with two people.

    also my wedge angle is about 35? (a wild guess) degrees. What would it be in south Africa? 80 degrees? Might seem like a scary wedge to home build or even to use a commercial unit. A GEM would be nice, but you'd have to get a nice one and you would jus need the optical tube and get rid of the Meade fork and computer. With this in mind, consider a lightweight refractor on a GEM for photography instead. Nothing wrong with having two or three or four scopes!

    80 degrees? More like 26-30 degrees, depending on location.

    Hi all

    Thanks so much for the replies and sorry for my late reply (I have been away)

    Currently the GEM seems the best option but I will need to save for this!! Some of you suggested making my own... this sounds very scary for someone with minimal maintenance skills!! I will have a look of YouTube for some help but any links would be appreciated.

    In the meantime I have ordered a T-Adapter and will start dabbling with stacked images of the moon and maybe some planets with the use of a 2 x barlow.

    Many thanks for all the advice!
