Description

Hi!! "Back to my backyard reality": No money for a mono camera yet...but this is a test with QHY8L and Optolong Ha 7nm...and how we could do to preprocessing it! After Ill try OIII 6.5 nm as well!!

11 x 400s Ha
11 x 400s (color)

Although all the difficulties and a long time reading articles on the Internet (many sites and Cloudy Nights forum), I think it was a very nice test and I enjoyed it too much!! The main workflow I used is:

1. Acquisition, calibration and debayering;
2. Extract Red Channel of debayered images;
3. Registration and normal stacking of the red channel...well Ha is ready...:-)

BUT...the postprocessing is very time consuming (I think)...you have to try a good match with Ha background and RGB stars!!! Sure Ill have to practice a little bit more...but I think this effort worth to be published...hope you enjoy!!! :-)

Im really sorry for overall guiding, but I had few hours to make this test...so, probably the alignment was not so good...

Warm regards, Daniel...
