I have finally gotten around to processing some images of an old favorite target - M1, the Supernova Remnant in Taurus (http://www.seds.org/messier/m/m001.html).

This was taken on January 15 & 16, 2007 and consists of 170 Minutes LRGB data (L 50 Minutes - 10x5min, RGB 40 Minutes 8x5min). I reduced/debloomed in Maxim DL, aligned and stacked in CCDStack, performed gradient removal, color combine, and noise reduction in PixInsight (http://pleiades-astrophoto.com/), and final processing in Photoshop. This was taken through a C-11 @ f5.95.

A full-sized version (http://obsballona.net/coppermine/displayimage.php?pos=-48) is at my web site (http://www.obsballona.org/).

Thanks for looking!

I like the crispness of the stars in it.

So your 822 Lalage in the animation on your website was a case of serendipity? That's great!

That's a great image.

CCDStack has a very easy routine for reducing and deblooming, you should give it a try. In fact, I think CCDStack does a better job of deblooming than any other program. It will also easily remove fairly complicated gradients and color combine. Try doing your initial processing in CCDStack then take to PS for the final.

Tom,

That's a great image.

Thanks!

I use MaximDL for reduction because I like how it does most of the work. CCDStack allows more direct control, but you have to create each of your darks, flats, etc. for each filter yourself.

I have found that the "reject blooms" algorithm in CCDStack just doesn't work. It leaves behind artifacts around the stars, and does not fully remove the blooms. Ron Wodaski's plug-in for MaximDL works quite well.

I have also been trying out PixInsight (http://pleiades-astrophoto.com/index.html). It has somewhat of a high learning curve, but is extremely powerful. The gradient removal, sharpening, and noise reduction tools are quite good.

Clear skies,
