Project: M106


I am waiting for the weather to clear so I can shoot some color for this galaxy. This is M106, near Ursa Major. It is a large and very violent spiral galaxy said to harbor a Black Hole in the core.

Shame I cut off the small galaxy next to it. I will have to redo the image, I guess.

Scope: Celestron C6S w/ .63 reducer
Mount LXD75
CCD: ST7
Filters: UV/IR block
L: 15 thirteen minute images

NGC 2681 - maybe?


I thought I was imaging the relatively obscure, NGC 2681 when I shot this. After comparing it to other shots of NGC 2681, I am not so sure what it is.

It is a spiral galaxy, but it is definitely not NGC 2681.

This sort of thing happens occasionally, since imaging these tiny galaxies is a lot like taking a picture of a grain of sand on a beach a mile away.

Eskimo Nebula in LCMY color

I shot this image of the Eskimo Nebula with a full moon out. It was sort of a "target of chance", since I was actually hunting for Comet Lulin, but could not find it in the glow of the moon. This nebula is so named because it resembles a little eskimo face at high magnification. My image is sort of small, being shot with a focal reducer, but I did bring out a bit of color. Something on my imaging set-up was dragging, though, causing a small swing in my guider. The stars are not completely perfect.

Scope: Celestron C6-S
Mount: LXD-75
CCD: SBIG ST7 w/Atik filter wheel
Filters: Edmund CMY Dichroic
Focal Ratio: F6.3
L: 6 @ 60 seconds
C/M/Y: 6 @ 60 seconds binned 2x2

M108 - Now in Color!


Here is my earlier image of M108 colored with CMY coloring.

C = 5 images @ 13mins 2x2 binned
M = 5 images @ 13mins 2x2 binned
Y = 1 image @ 13mins 2x2 binned (What can I say? clouds moved in.)
