Bat Nebula IC 1340 - very faint

Heavily cropped and flipped to  match alphatripleplus image, plus annotated  slightly cropped original SC output (Happy with the way flats compensated vignetting).

 

Experimenting with the recently acquired HEQ5 mount plus Sigma TF at 400mm. Need to invest in a decent refractor for this mount, but I like the flexibility of the telephoto for changing FOV.  

 

 

65 x 15 secs at 300 gain

ASI 294 MC PRO at -15 C

ZWO UV-IR cut filter

Sigma TF at 400 mm

SW HEQ5 pro mod

Flats x 25

Darks x 25

Sharp Cap 4 output cropped

Would have done longer integration, but the TF decided to slide back down to 120 mm when it was completely vertical? Lock doesnt work!

IC 1340

 

now I can correct my earlier mistake: despite some trouble with my gear and interrupted by clouds I managed to do the EAST Veil with IC1340 at last:

 

Loc: south of Stuttgart, Germany

Scope: CPC800 on wedge

Camera: ZWO ASI 294 MC

Filter: Broadband UHC

 

6 x 64 sec / 300 gain / flats applied / image resized

I'm curious as to what is your total exposure?  (From the caption, I assume you are using 5sec subs).
