Veil thru IDAS NB3

I didn’t take through NB2. I forgot about that, or might be too sleepy to do more…… So this is only NB3 image.

0705a

NB3-52 + BORG 72FL F4 (prototype) + modified SONY A7, 3 minutes/ISO4000. No dark/flat. Simply stacking 20 light frames.

I think OIII filaments more show up as expected. 72FL F4 looks creating very flat illumination entire full frame sensor.

Followings are the summary of IDAS Nebula Booster Series.
