Attaching Camera Directly to SE or SLT Mount
      #6055689 - 08/31/13 09:16 AM

I have an SLT and a 4/5se mount. I am looking for the best way to attach a camera directly to the mount vertical arm slot. Ideally I like to use the built in wedge on the 4se mount and polar align and track. I recognize that in this config I would be limited to <1min exposures without a guide scope, but wanted to keep it simple as I get my feet wet.

This would be an alternative to piggybacking to the OTA because I have not figured out how to do so with the my smallish 127 SLT MAK tube - unless someone has advice on how to do that. Would the Celestron piggyback adapter bracket sold for the 5/6/8se work on the 127 SLT MAK?

Thanks in advance for any help you can provide.

If you have an Orion/Synta sized finder dovetail shoe on your scope, you can use this to attach a camera via the finder dovetail:

To attach in place of the OTA as you suggest, you can just get a short piece of vixen-size dovetail rail and bolt the camera to it. A camera's tripod screw is a 1/4-20 thread so you can get a bolt with that thread size at any hardware store. Here's a source for dovetail rails:

Dan,

Thanks so much for the link to the finder dovetail mount adapter. That item reminded me of a small clamp mount I was using for a webcam that should provide enough adjustablity, yet rigidness to prevent vibration to allow me to piggyback my digicam to the OTA by clamping onto the finder mount. Much appreciated.

Here's some ideas. Check the second generation camera mount near the end.

Arctic Eddie,

Thanks for the link to that nice SE mount AP camera setup. When I get a "real" DSLR (I'm working with a superzoom with significant limitations, but hey I'll push it to its limits) I will have plenty of ideas for setting up my AP rig.

And if you're really cheap (like me) and have a table saw (like me) you can make your own dovetail. Rip a piece of 3/4" thick wood (a pine 1x4 will work fine) with 15 degree angles, about 1-7/8" on the long side of the resulting trapezoid. My 8SE mount accepts a wide variation in width, so if you miss the 1-7/8" you should still be fine. However, I needed to add a spacer between the camera and the dovetail so the camera would clear the clamp. (The rail pictured was made in a hurry out of bad scrap, including one piece that wasn't exactly square, or free of cracks!)

If you're mounting something heavier, use oak.

Brian

Brian,

Thanks for the pics of the DIY wooden dovetail. I'm a terrible carpenter but even I could probably pull that off. Thanks for the additional ideas.
