Flame/Horse Nebula / Ha

Hello everyone.


My 314L+ is real-estate challenged, so I tried AP's CCDT67 to see how under-sampling trade for FoV looks like... this 1h40m Ha is drizzled 2x and stretched.

Calculated 3"/px ED80 @ f/5.4 with the distance of the reducer is 65mm from CCD sensor.
I have a SW 0.85x FF/FR ... but I assume the small sensor not need flattening and the CCDT distance adjustable for the desired FR reduction.

Happy to hear suggestions


Cheers,
Mick

Edit: replaced BW with false color Ha.
Edit 2: changed back to BW
