M57, The Ring Nebula
Object: M57 (NGC6720)
The Ring Nebula - Planetary Nebula
 Const.: Lyra
Camera: HX-916 Scope: C8 Mount: AP1200GTO
Filter(s): L:R:G:B Exposure: 16x60s:12x60s:12x60s:12x60s Binned 2x2
A recent image of the Ring Nebula, M57, a planetary nebula in Lyra. The luminance channel is a stack of 16 two minute exposures taken with an 8" f/10 SCT. The red, green and blue channels are each twelve minute stacks. The images were combined and balanced automatically using AIP4WIN's fully automated color tools, using the G2V Color option.
 
M57, The Ring Nebula
Object: M57 (NGC6720)
The Ring Nebula - Planetary Nebula
 Const.: Lyra
Camera: HX-916 Scope: C14 (luminance), AP130 (colors) Mount: AP1200GTO
Filter(s): L:R:G:B Exposure: 39x30s:14x30s:14x30s:14x30s Binned 2x2
In this color image of the Ring Nebula, M57, you can just make out the barred spiral galaxy IC1296 in the upper left quadrant. The luminance channel uses the 20 minute exposure taken with the 14" f/11 SCT, shown at the bottom of this page. The red, green and blue channels are seven minute stacks shot through a 5" f/6 refractor. The images were combined and balanced automatically using AIP4WIN's fully automated color tools, using the G2V Color option.

The Ring Nebula, M57, a planetary nebula in Lyra. This image is a stack of 6 one minute exposures using a 5" f/6 refractor. Image processing was performed using AIP4WIN. This image has been cropped down from its original size of 1300x1030, you can click on the image to see the full frame view.
 
M57 and IC1296
Object: M57 (NGC6720)
The Ring Nebula - Planetary Nebula
 Const.: Lyra
Camera: HX-916 Scope: C14 Mount: AP1200GTO
Filter(s): IR block Exposure: 39x30s Binned 2x2
A much larger scale image of M57 showing the background galaxy IC1296. This image is a stack of 39 thirty second exposures through a 14" f/11 SCT. The camera was used in its 2x2 binning mode, yielding 0.71 arc-sec/pixel, slightly oversampling the image. The images were stacked and 15 iterations of a slow R-L deconvolution were performed using AIP4WIN.
