Diego Naufel:Hey , nice pic.
"Optic: Vixen VSD100 at F3" ??
But I want to know, why stars are so big, and have spikes ?
Spikes can be digitally added, but stars profile are not tipically from a F4 unobstructed refractor. It seems like a short focal newton with medium/big size obstruction picture.
Maybe picture information is incorrect, and image was taken with a catadioptric telescope?, perhaps a taka 180.
Can you clarify this?.
Thanks.

Mohammad Ranjbaran:Thank you very much for your data, help and guidance.
As a matter of fact, I just use Photoshop to deal with all the processing issues. But I certainly consider using PixInsight if I found myself very serious about Astro-image processing in the near future.

amir:Dear Mohammad, I had focuse chsnging problem while collecting data on green channel. I will change data as soon as I could collect again.
For correcting color it is better to use color calibration methods. In PixInsight, PhotonetricColorCalibration data will correct it.
