This was shot over a couple of nights recently. The
Ha was limited to 3 hours and the O3 to 4 hours. The humidity was extremely high (water dripping off equipment at end of night) but at least no fog! These cooled cameras with NB filters do an amazing job of rejecting the
LP. The moon was over 60% illumination when the O3 was captured.
I would like for the Tadpoles to stand out more, but, not too bad.
It was a tough transition from
DSLR to NB imaging, but, I'm soooooo happy I made the change.
By the way, does anybody else see a dragon in the Flaming Star nebula that is looking right at you? Looks like a dragons head (kind of like an alligator's head with snout) with wings and body behind. Maybe I've just been processing it too long (chuckles).
WO STar 71 telescope, CEM40 mount, ASI1600MM camera,
EFW filter wheel, Chroma 3nm
Ha and O3 filters
Controlled with
APT and guided with PHD2. Processed in Pixinsight.
18x 600 sec
Ha (3
hr), 24x 600 sec O3 (4
hr) [Total exposure 7 hr]
The camera was rotated 90 deg clockwise to get both nebulae to fit in the
FOV. Of course this necessitated shooting a new set of Flats.
Hope you like it.
