Easy attachment Piggyback mount for DSLR - no screws in scope
Posted by Poppa Chris on Tuesday, December 28, 2010 11:00 AM

First, my thanks to Aratus and Tim Kerr for my inspiration...

I must admit that I am a rank newbie when it comes to astrophotography.  But the efforts of my forum friends has been most helpful in my "learning the ropes".  To date, all of my efforts have been with unguided photos of the Moon and Jupiter, either handheld, camera on tripod, or quick single eyepiece projection photos.  I felt from the advice of the sage forum members that piggyback photography was a natural first step in guided photos before jumping into more difficult waters.  I ordered a Celestron SCT Piggyback mount but found upon its arrival that the real estate on the rear of my CPC1100 was a precious commodity.  I needed to mount the camera in a different position to clear my two finders, a 9x50 finderscope and a red-dot reflex finder.  Also, I wanted a bracket that would mount and demount easily as I am much more of a visual observer than a photographer at this point.  I gave this some thought and came up with a fairly decent solution.

So welcome to the wonderful world of velcro...

Screws for standard mount are used to hold the Velcro strap

The mount is padded on the bottom with rubber to provide non-skid and vibration dampening properties

Sticky-back Velcro "positioners" are added to scope and bottom of mount (removable with no marring of scope tube if needed)

Mount is strapped to scope tightly to compress rubber pad for maximum stability

Supports DSLR with long 55mm-250mm Zoom with no problem.  Note: Velcro positioners installed as close to the scopes Altitude axis as possible to reduce counterbalance issues.

Camera does not disturb views through either finderscope

Now that the engineering is done. Here are a few examples of my meager results (I never claimed artistic ability).  I still find that focusing the camera is my largest hurdle, but I am getting better with practice.  Please bear with me...

Pleiades @250mm

I hope the above is useful for those wishing to start astrophotography via piggyback.  If it does provide someone with good assistance, then I'm happy...

I'm impressed.  Forgive me, the less experienced one, but what constellation or cluster is this?  I do note the colors, the details that are beautiful!  A new toy to raise as your own.  I'd be proud, too!

Thanks much!  Although I have been a visual observer for over 3-1/2 decades, I'm a total novice at astrophotography having only decided to pick it up in July of this year.

The 6 pictures I posted are 2 of the Plieades, 2 of the Hyades (in Taurus), and 2 of Orion

This was my first attempt with this new piggyback mount, and the sky conditions were a lot less than desirable.  The night was a little misty with thin clouds swiftly moving through with an approaching front. 

But I was lucky to get this session in at all.  It rained the next morning.  It's been cloudy and cold ever since.  My fireplace hasn't gone cold since Christmas.  I've managed to burn 1/2 a cord of wood so far this season with 2-3 months to go!
