Apologies if this is the wrong forum. We really need a CCD subcategory under "equipment," but i digress. This didn't really belong in the beginner forum since this isn't beginner equipment (I'm in way over my head, I know...)

 

I have had an STT 8300 with self guiding filter wheel for quite some time and haven't used it yet other than to test dark frames.

 

I picked up an AO8 on CN a few weeks ago and ordered the requisite plate to convert it to the T version. There was an order mixup so the plate didn't arrive till last night.

The AO8 came with a square plate which had a rhreaded opening, but no caps. Boight used, but the shipping foam was on both sides of the optical lens.  The self guiding filter wheel has a circular piece with 4 screws. My 2" adapter nosepiece is threaded into the circular piece.

I found the instructions quite lacking. There is no update to the instructions that I could find for the AO8T.

Here's what I came up with on my own (picture essay)

Attach the new to me 8T cover plate with the 4 screws that were just removed from the filter wheel. I temporarily put the 2" nose piece back to protect the filters.

Remove the nose piece and fasten the ao8 to the ao8t cover plate with the 4 screws. Note if you are upgrading like I am, you will remove the standard cover plate first, of course.

 

See how the T cover plate has a semicircle at the top, this fits where the original annulus piece went.

Pic 4 is also after I removed the square block that was held in by 4 very short hex screws.

I pit the stubby hex screws back here without the square block, then reattached the 2" nosepiece.
