H-Alpha 18.04.17 (Disk Only)

Mostly for my own benefit. lol. Lots of thin cloud/contrails! BUT I do seem
now to be able to improve Full-Disk Images via application of a FLAT!?!
Notably at "data taking" stage in FireCapture rather than post-processing:
(For anyone caring... Using the "Fruit & Veg BAG" idea from Alex et al.)

Really does need less variable conditions to confirm anything though...

Stunning well done...

[Pete Presland]

Lovely disc, good to see some new action on the way.

Nice disk Chris. Looks like things may get a bit more lively over the next few days.

I know! Heheh. Genuine thanks for encouragement / interest here!

Starting to get quite enthusiastic. This a BIGLY blown up region of
"pixel variations" I now get -- In exchange for Newton's Rings!?  

Left side without a flat... Right side *with* (Morrisons!) BAG Flat...



BAG is significantly higher opacity than (negligible) cling film. I have 
to boost the exposure time by a factor of 20x to take the FLAT. 
But, for full disks, it avoids the (inevitable?) collimation problems I
get using "extreme de-focusing" (which always left "bad edges"!) 

I never seem to get far with OFFLINE flat removal on Full Disks!
Not many seem to try REAL TIME Flat removal with FireCapture.
It seems a real possibility? The author seems like a "Good Bloke"
(a.k.a. FINE programmer!) So Kudos to Mr. Torsten Edelmann! 

Who Knows? But If I can encourage folks to try random  stuff...
