OK I'll start off this month :-)
I had a go at NGC7635 the Bubble nebula last night.
I took a combination of normal and Ha exposures to increase the number of stars showing. It was pretty blustery last night, and though I grabbed 62 frames, only 23 were usable. I also waited too long to take the normal exposures, so the sky was getting a bit bright for the SC3 camera and I was only able to get 8 frames.
Taken from Harrow in the UK, 040522 from about midnight (UT) onwards.
The image is a composite of 23 x 120s exposures with an Astronomik 10nm Ha filter, and 8 x 20s normal exposures. Shot with a ToUcam Pro SC3 through a Vixen VC200L and a 0.5x focal reducer, mounted on a Losmandy GM-8. Recorded in K3CCDTools v2, aligned and stacked with Keith's Image Stacker, then adjusted with the Gimp.

Here's my first proper attempt at deep sky astrophotography.
Any tips anyone?

M57 - Ring Nebula
LX90 @ f/10 in alt-az mode, 18x30sec images, ISO1600, Canon EOS 300d, Photoshop 5
Sky was a bit hazy and a 75% moon didn't help either - that's my excuse anyway ;)

M27 the Dumbbell Nebula
Harrow UK, 040530

This image is an LRGB (HaHaGB) composite comprised of 42 x 60s exposures in Ha used as L and R, 30 x 20s exposures in B and 30 x 40s exposures in G. I used an Astronomik 13nm Ha filter, an Orion 58 green filter and an Orion 80a blue filter for these exposures.
Taken unguided with the ToUcam Pro SC3 at prime focus of the Konus 80mm short tube refractor at f5. Recorded in b/w RAW mode in K3CCDTools v2. Alignment and stacking was done with Keith's Image Stacker, image adjustment and colour balance was done with PhotoshopCS.

This was posted earlier this week in the CCD forum.

My name: Eric Africa
Date of photo: June 5, 2004
Description (title) of the image: LRGB M51

Relevant photo information:
Equipment: SBIG ST-7E with CFW-8a filter wheel shooting through a Takahashi FS-102 on an EM200 Mount.

L: 2 x 10 minutes binned 1x1
R: 2 x 10 minutes binned 2x2
G: 2 x 10 minutes binned 2x2
B: 3 x 10 minutes binned 2x2

This is just my third attempt at LRGB imaging. The shortness of the L data is just so I have an L to work with; I have a 90-minute L image taken earlier this year that I hope to merge with the color information.

Omega Centauri
Keys Florida
Mark Keitel
Scope: Tak FSQ 106
Location WSP 2004
Camera: SBIG 10xe
Exposures: RGB 9 x 480sec each filters
Mount: AP1200 ( the TakFSQ is one of three scopes on the mount a TakFRC300; TakFSQ106; TakFS-60c)
Weather was winds 20mph with gusts up to 40mph. Was in a Kendrick tent and could not image that night with the large scope. The wind was so strong that guiding was an issue.
Being that it has been raining and cloudy here lately gave me some time to look over some older images. I found that I had the Red and Blue channels mixed up. ( I know have a different filter wheel that I personally put the filters into and labeled them so this would never happen to me again)
I think that the little miss-hap and the end results are startling

If you want to go galaxy hunting in the image I suggest you view the larger image and find the following
1) PGC 47003 @ 14.0mag
2) PGC 47092 @ 14.1mag
3) PGC 47306 @ 17.0mag, 21arc.mins below PGC 47092 .
4) PGC 47340 @ 14.5mag in the lower left corner of the image.
5) LEDA 159037 @ 16.3mag on the middle left edge of the image.
6) LEDA 159028, no Mag given, 4.8arc.mins left of LEDA 159037 the image.

Large 2.9mb

Thank you


* If you are one of the lucky ones that can not get to the image by clicking on the link and get a forbidden message you can then click the goto button on your browser after you get that message and it should work or you can simply copy and paste the link into your browser and then hit goto and that should work too

Not sure if I will get the color of this image done soon since it is rainy season here in the Tampa Florida area
