QSI683wsg Adapter to connect guide cameras

I was having trouble getting my QHY5L-II to work with my QSI683wsg.

The QHY has a longer backfocus than the standard 12/5mm and would not reach focus using the usual QSI-supplied adapters.

I did some improvising of my own but while doing that, was introduced to these little beauties. They are made by a fellow named Gary Jarrette in the states - he's retired from work at the Uni of Arizona where he designed and built a number of components for various space missions including several of the Mars surface missions. Apart from being a clever bloke, he's also delightfully helpful and generous with his time.

I ended up with a sexy blue (matches the QSI) job that is rock-stable but still allows you to fine focus your guide camera (by means of the little knurled wheel) and to then lock it in using the 3-screw compression ring built into the body of the device.

It beats the dickens out of my DIY attempts that's for sure.

His work is great - I almost bought his adapter that fixes the supremely dodgy guide cam holder in the SBIG ST series OAG (SBIG REALLY screwed the pooch there!). In the end I didn't as I went guidescope again.
