1 hour rosette from the balcony

Post by orly_andico »

6 x 600 seconds.

i used a stacked IDAS LPS-V4 and Red #25, which is equivalent to a 20nm H-alpha bandpass (http://www.sciencecenter.net/hutech/haimage-v4.htm)

had to throw away 3/4 of the pixels on my QHY8 because only the red pixels respond to H-a light. Then used Carboni's actions (B&W -> false Ha) on the red channel.

so troublesome and for pretty mediocre results...

and an "enhanced" version - which looks a bit over-processed...
