Experiments with optics

I was trying to match the Celestron 0.63reducer with the FLT132 ..
This combo suppose to reduce the FLT’s F7 to F4.4 and make it 583mm scope. And guess what: it DID!!!
Although guiding was an issue yesterday, here is a single 900s Ha (just stretched) frame of wide NGC3293+NGC3324.

hello ian, are you saying you attached the celestron 6.3 to your frac?
that is amazing, how did you do it?

Fascinating, so was it easy to attach and what's that arc on the top right?
Cheers

Nice work, Ian.

You've solved one mystery for us: what lies beyond the faint nebulosity behind the gem cluster (below left of centre). You've shown both how it interconnects with the Gabriela Mistral nebula, and how it overlaps a huge ring-shape at the bottom left of your image. (I'm guessing that the superposition of the gem cluster is just a line-of-sight thing.) So now, we know. Thank you.

I utilized EOS camera adaptor and “forced” it on the fine thread of the reducer locking it with those 3 tiny grubscrews … it’s rather not elegant but does the job …
