I couldn't resist when I went outside last night and noticed Orion up over my neighbors tree around midnight last night. I quickly set up the scope and camera and got a little over three hours of Ha data. Thanks for looking.

With my CCD's however it does not get as sharp of details as the 6nm NB Astronomik set.. Great image.Other than some field rotation it looks perfect. I personaly prefer changing the image to greyscale.You get a lot better contrast when you do that too... Just my preference though.

I agree that the greyscale shows more contrast , that Ha data will go really well with some RGB when you get a chance. -------------------- Erik Orion Atlas Self Hypertuned (EQMOD) Orion ED 80 Williams Optics VII reducer Celestron 8" SCT Orion Starshoot Autoguider PHD guide Canon 400D Hap Griffin Mod w/Baader filter Astronomik clip-in LP filter and 12nm Ha Stilleto CVF and Bahtinov mask Tamron 75-300mm&28-80mm lenses NexImage webcam http://www.flickr.com/photos/31986095@N05/ Post Extras:       Samir Kharusi scholastic sledgehammer Reged: 06/14/05 Posts: 983 Loc: Oman Re: Horsehead and Flame w/ Astronomik 13nm Ha Filter [Re: Nils_Lars]       #3425014 - 11/02/09 06:44 AM Edit   Reply   Quote Quick Reply   Unfortunately our eyes are lousy at seeing contrast in Red or in Blue. He could of course use ha=Green as in the Hubble palette, or he could simply use masking and make it a false RGB until he gets the opportunity to capture a few minutes of star colors. Rudy, here is your same image with contrast boosted by making bright reds pink (adding a bit of white to the brightest portions), stars white, and the sky background a greenish blue: Basically a nice image to play with endlessly... I found that pure red comes out even worse/flatter in prints than on a monitor, hence when I tried to get a decent print of one of my first Ha captures I resorted to this kind of false color. It's basically a nice capture, well worthy of caressing -------------------- Bored?

I haven't played with the data too much, but am waiting until I can acquire some RGB data to combine with it. Seems like there's a lot of potential in this one. Erik and Gary, Thank you for your comments.
