NGC 896 in Ha Mostly

Bad seeing and clouds conspired to prevent a nice image. But I decided to post this anyway. This is a part of the Heart Nebula, the most brilliant in fact in any narrowband shot.

I will definitely be giving this another go this week.

I’ve been working on my narrowband imaging. Up till now I haven’t been happy with the results. It always seemed that the Ha had significantly more detail and depth than the final Ha, OIII and synthetic green image. The combined image always just seemed washed out.

I also have just been unable to really get some usable OIII data for the Heart Nebula with my 350D. I just get too much noise as I extend any subs past about 12 minutes.

So I decided I would really just combine use the OIII data to smooth out some of the details of the Ha and balance the stars to make them white again.

My goal was to keep the depth of the Ha data with its contrast and wow factor (when seen in the color version minus the noise from the green and blue channels) but balance out the stars, and highlight along the edges of the tendrils in this portion of the nebula.

Here is what the Ha only version looks like -

I actually finally like this image after a lot of fiddling. I tried not to overprocess it.
Telescope: LX200 8″ with f/6.3 FF/FR
18x10min Ha
30x10min OIII
Lots of Darks(40), Flats (60) and Flat Darks (60)
Stacked with Nebulosity, Processed in Photoshop

Double Cluster with Comet Hartley Widefield – 35MM

Because I am tired of imaging through an off-axis guider with my 8″ Meade LX-200 I decided to shoot some widefield images over the past week while the Comet Hartley was rampaging along Cassiopeia. These are two different processing passes of the same image. On the first image on the left I have tried to cut down on some of the skyglow light pollution I was getting from even these dark skies by enhancing the darker dusty areas of the shot. I am actually trying to figure out which one is better, so your comments are appreciated.

Details of the Image:

58 x 3 minute Subs – stacked in Nebulosity

60 x 3 minuted Darks

60 Flats

Canon 350D unmodified piggybacked on my Meade LX-200 8″

Shot with my wonderful EFS 17-55mm lense at set at f/4.5 and 35mm

Processing done in Photoshop, GradientXterminator and Hastalavista Green plugins used for some of the finer points.
p.s. I just bought a modded 350D so I can hardly wait to see the difference.
