Techno Stuff: 6/20/07 Camera: ATK-16hr, Imaging Scope: Megrez 80mm APO at F/6, mounted on LX90 8" SCT, Ha 6nm 80 min total with 20 min subs, OIII 14nm 90 min total with 30 min subs, no binning, Darks Applied, Autoguided with QGuide and PHDGuide from LX90, , Processed with CCDStack, Photoshop CS2, PixInsight

Notes: This is an Ha:sG:OIII narrowband image with Ha mapped as red, OIII as blue and a synthetic green generated from the Ha and OIII images. I took this back on June 20th but didn't have a chance to process it until now.

I didn't plan on the colors turning out this way but I think the black and orange are appropriate with Halloween just around the corner. :>))

In the two images below the colors are remapped to red:green:blue respectively.

Here's an Ha:OIII:OIII version.

Woe! Rick! Those are scary-looking- ominously-beautiful-outrageous over-the-top images of the "Elephant Trunk". Ahhhh! You are perfectly correct regarding the colorful Halloween spectrum that popped out.

Keep on searching skyward,

I hope I made it look scarey enough. After all, it is getting close to Halloween. :>))
