Hi David, guys,thanks for the comments,

Yes David, I did the 50mm chop as per Clive's great article here:

This easily brings the DSI II into focus even with the homemade
filter wheel assembly
attached, which adds approx 22mm to the
equation.

Can't wait to see results from that!.....is it the mono version?

I have tried a few colour sets.
Nothing earth shattering to offer so far.
A lot is down to inexperience.
Colour balance is hard to get right. The Meade set (cheap) need
about 10sec exposures of RGB to match the 5sec luminosity subs.
No science here, no G2V calibration done yet...all estimates so far.
A work in progress.

That's the key to it David
