Very impressive John - well done! 8-)

So what line-up are you using: is that Quark just fitted on the back of your refractor (and do you need any energy-reduction filter on the front)?
Do you need your focal-reducer in front of the camera to get a wide enough field of view?

I've tried different combinations with the Quark, what I'm lacking is different size's extension tube's.
I seem to get sharper focus with a reducer, some say use a barlow but I think that's going OTT.
In the photo above I have a 1.25 UV/IR filter screwed into the front of the diagonal, then the Quark, and a .5 reducer screwed into the front of the camera nose piece.
Another combination I've tried is, scope + UV/IR screwed into the front of Quark + flip mirror + .5 reducer + camera.
According to Quark and other user's you do not need a ERF on the front of the scope size of 80mm and lower only a UV/IR filter. The Quark as a 4.2 barlow incorporated inside the Quark.
With having such high magnification the Quark is equivalent to more larger and expensive Ha scopes at a fraction of the cost.
I've tried visual with a 32mm Ep but can get about a 1/2 of the disk in the FOV. Some say a 60mm scope or there about is the sweet spot to use.
This what happens when your rushing around for your first view, I forgot to take the dust cap off the Quark.

Oh dear - that's the second time I've seen someone set fire to a lens-cap (the first time was at Kelling Heath a few years back)!
:idea: I hope that you remember to keep the front of your finder-scope filtered (or capped) too - that's another potential source of disaster...

No I remove the finder scope and just use the home brew sol finder butted up to the scope tube rings with Velcro tape around both of them surprisingly accurate.

these are just screen grabs and no processing with different camera's and different combinations of focal reducer's
