They stars were peas at what seemed to me optimal placement!

So I got the ZWO today. A few comments:

1. The prism being able to slide in and out is very useful - I have positioned it just outside the light cone of the 1600M's chip

2. The holder for the 120MM was a bit wobbly - just a smidgeon when I had tightened everything and showed the folk in the store. Turns out when I got home there was an Allen key for the prism cell that just hadn't been tightened correctly - everything is snug now!

3. Mating the OAG to a Meade motor focuser gave Bintel some confusion (or just the first server). Luckily I brought in the whole old unit - Lumicon focuser, attachment to Meade Motorfocuser (that I'd originally bought of BinTel) and both ZWO Cameras. It took some struggles but two threaded adapters later and I had exactly the right connectors. It took (quite) a bit of asking it looks like a smooth 50mm wanting to connect to a 48mm threaded socket - what can you sell me to mate to it - until eventually something worked perfectly!

4. The ZWO 120MM body is large enough that it can only be connected to the OAG and not hit the Filter wheel when mounted upside down.

5. The sliding ring tube spacer on the 120MM has a tightening bolt who's head is wider than the tube - so it can't sit in flush to the tube if its almost racked all the way in!

Attached is a shot of all the gear attached - now for a clear night to see if it's all looking good when focused and space correctly! Last night I tried my backup guider - a piggy backed WO 98mm using a QHY5-IIL - stars were pin point in PHD2 - so fingers crossed!
