Spitfire

What a terrific image. Great wide field and I can't see the join! Can you give me more info on the filters you have used......bandwidth and maker? Geoff

Great image! Is this one of those objects that can only be seen with the 3nm filters? I had a bit of difficulty finding this, but after some research found these coordinates: RA: 20h 10m 14.2s Dec: 36deg 10 min 35.07sec Geoff

Nice Image. I enjoy looking at these unusual galaxies. Geoff

OK, I'm not an expert by any means. On the first image the "trail" is exactly in line with the spider star lines. On the second image , the spider lines are there (but rotated from the original) and no "tailing". Could it be a reflection off the spider in the first image and you have re-positioned the Scope on the second image hence no reflection? The 2 images are inverted from each other. Did you have a meridian flip? Geoff

Thanks All, yes indeed it is CTB-1 (or Abel 85). When it was found, it was thought to be a Planetary Nebula, and given the label Abel 85. It has since been re-assessed and now is believed to be a Super Nova Remnant. It has also been given the name CTB-1 but has not been given a SN number and not logged into the list of Super Novas. Hence I couldn't find it! Geoff

Discovered this object whilst testing out my "new" Eagle3s It looks like a Super Nova Remnant. It's in Cassiopeia at approx. RA: 0h,0m,20s DEC:62d,29m,38s. It is faint, thin and about 1 degree in diameter. My PHD guiding didn't work so this is 47 x 2 minutes unguided in Ha. It is not a Sharpless object and I cannot see it in any Super Nova list that I have seen. Any ideas? Tech Details: Scope: Takahashi Epsilon 180ED @f2.8 Camera: Modified Atik 4021 Filter: 2inch Baader 7nm in EFW3 Mount: EQ6 with Rowan and EQ6 Wedge3 mods Geoff P.S. Just seen this in Tom O'Donoghue's brilliant 25 pane mosaic in the top right hand corner.

That's a great image for so little exposure time. Can't see what your equipment is but I'm guessing it's a Takahashi Epsilon with an Atik 383L+. Geoff

That is one hell of a nice image. The detail in the "head " of the trunk is really good. Geoff

Alan, I seem to have an adverse affect on electronics. This is why I don't publish too many items! The image was coming up on Windows Photo Viewer after a long wait. I'll try again with the "choose file" option below. Let me know if it works.sh2-150ha50%.tif Don't know what is happening as it only wants to be in this position on the text and doesn't open as an image. Anyone else having the same problem? OK so it wants to be in 2 places. Said electronics don't like me! Geoff sh2-150ha50%.tif

Alan, your image is great, it just requires a bit more data. I've stolen some notes from Dean Salman's web page "CCD Images of The Sharpless Catalogue" as follows...... " Shooting a lot of RGB color is a good idea because there are a few nice reflection nebulae in the area that would be hidden using just the H-Alpha filter. The reflection nebula comes out very nicely over time. Using just a clear filter for the luminance is not going to work very well, so if you don’t have an H-Alpha filter, use the red as a luminance to help pick up the vast nebula in the area". Your "black hole" on the right is there and a bit larger than your image shows, so it's not your flats. I took this image 3 years ago, I don't know if it will help but may be useful as a comparison.

I think that is a very nice image. Wish I could produce one of that quality. Geoff
