NHC 6188 in Ara - widefield Ha
Here's another one from last night testing the new FF with the ED80.
This is a two panel mosaic (left & right overlapping) . The right panel was shot first from fairly low altitude to “reasonable” but the left was mostly taken all the remainder of the night till the zenith. 30x5min for the right and 15x5min for the left. The field is approx. 2.6 x 2.3 degrees.
Bit of a challenge to process as it is very noisy. The ED80 is small aperture and with Ha not much light makes it in. Also because of the difference in exposure time between the left and right I had to deal with gradients and levels issues. Definitely a target for the hyperstar. The point of the exercise was to test the WO field flattener for the scope and it worked very well.
I’ve also posted a bigger version here [2.5MB] if anyone’s interested. Thanks for looking.
