I’d love to own a Q7 if I could attach the barrel to my Mach1 losmandy D mount. I could the use it for finding double stars, something I think the Q7 might be good at. Does anyone know what is needed and where I might purchase it?

Then for observing the Moon and Planets I could just use it with the classic fork mount.

Hi Jim,

 

I have a Q7 on an AP Mach1 GTO mount. It mounts very easily and nicely.

 

I use the Losmandy LMDUP 14" Universal dovetail plate which is screwed directly to the mounting bracket of the Q7. I keep this attached when storing the OTA in its case.

 

On the Mach1 I have the mating Astro-Physics DOVELM2 dovetail saddle (this appears to have been replaced by DOVEDV10 dual style saddle plate).

 

I purchased both from Astro-Physics, I would recommend calling them to verify the proper part numbers.

 

I will take some pictures for you tomorrow.

My Q7 Astro is mounted on a Losmandy GM 8.  I recently posted an image of my rig in the Cats and Casses forum here on cloudy nights.  An 11lb and 7 lb counterweight are used to counterbalance the OTA.   Two 7 lb weights could be used, but they would be placed at the very end if the dec axis. 
 

The scope is quite stable for visual use.  A sharp tap on the diagonal at high magnification results In a vibration lasting one second or less, depending on the tube orientation and eyepiece load.   I’m not a astrophotographer, however it is my guess that a more robust mount would be desired for imaging.

 

When I ordered my scope from Questar, I told Jim R. about my mounting plans.  I shipped my Losmandy dovetail and my University Optics finder shoe to New Hope so they could attach them to the instrument.  My Q 7 arrived ready to use on the Losmandy.

 

I’ve been very happy with my scope and mounting solution.  Although the mount is on a permanent pier, it is light enough to remove and transport to a darker sky site.  I keep the scope in its case when not in use.

I have mounted the Q7 classic T on a AP1100, with the saddle plate from AP, nothing else was needed.
