The optical tube assembly of my ‘scope is attached to the mount (and tripod) by a pair of clamps. Each clamp consists of two identical halves which bolt together on the sides forming a ring around the tube. A nice feature of this construction is that the bolt holes which are used to attach the clamps to the mount are mirrored on the top of the assembly.
So on my way home from work today, I picked up a couple of bolts and built a fairly simple jig to mount my camera ‘piggy-back’ on my telescope. What’s nice about this is the ‘scope and camera are reasonably well aligned, and the scope can easily be used for guiding the camera. You may recall the suffering I went through a while back trying to actually mount my camera to the business end of the telescope. Instead, I can use the high-powered eye-piece for my scope and manually track the star with the scope.
Obviously this is still far from ideal, but I wanted to get a sense for the effectiveness before I invested in any actual hardware (beyond a few bucks at True Value).
So I mounted the 70x200mm and opened it all the way up. Here was one of my first four shots which got lucky with a meteor.
It’s actually amazing how many of my shots caught a random meteor, or satellite or other random bit of space junk moving somewhere in the frame.
Kicking the lens up to 200mm adds quite a bit of detail.
Then I re-framed to pick up the Horsehead and Flame Nebulas to the left end of Orion’s belt.
In this heavily enhanced version, you can just make out the namesake features above the noise… but you wouldn’t know that was a horse if I hadn’t told you.
Then finally, a gratuitous Pleiades shot.
