Hello from Greece,

this is my second attempt at color imaging.

NGC 281 (pacman nebula) in Hubble palette

Location: Agrinio,Greece
Date: 8,17,24 November 2012
Telescope: TS APO65Q 65mm f/6,5
Mount: SW NEQ6 Pro with EQMOD & CdC
CCD: Atik 460EXM @ -5C
Filters: SX USB FW 7x1,25'' & Ha (7nm), Oiii (8,5nm), Sii (8nm)
Guiding: TS OAG9mm & QHY 5
Exposures: Ha 25x900 sec ,OIII 20x900sec ,SII 20x900 sec
Calibration frames: darks,flats,bias,dark flats
Preprocess: MaximDL,CCDstack
Processing: Pixinsight (just DBE) ,Photoshop
Capturing,guiding,dithering with MaximDL.

Unfortunately, i am imaging from a light polluted city.
Also, the moon was a real problem through the SII capturing
as it was almost full and close to Cassiopeia.

I would welcome any comments and critisism on the processing
as i am new to the procedure, and i know that this image can
get better.

Thanks in advance!

Nice work Angelos! Narrowband is the way to image beautiful targets in light polluted skies. Keep imaging and keep posting!

Very nice data. I hope you don't mind that I modified your image by using PixInsight's SCNR to remove green and make it look like regular HST.

Thanks for your comments guys!

Peter, you really made a difference there,
i like it a lot better.
I will try to further process it using some PI's tools.
