I found this M33 shot taken in 1987. Thought I would scan it in and try to enhance it a bit. I use a Canoscan N540P scanner it allows me to do some basic image processing and it works quite well in bringing out fainter details on low light objects such as M33.

Anybody know which Galaxy this is ? Lost my records on this one.
John


the big one is M106 and the small one is ngc4248. i solved your plate with the astrometry.net code.

here are a couple of scans. these are actually stacks of 10 and 8 pictures, respectively. i have done quite a bit of postprocessing to the stacks which kind of brings the images into the modern era - got rid of gradients, did a bit of color correction and emphasis of the comets, etc.

1) hyakutake

2) hale-bopp

details are in the flickr pages which you can reach by clicking the images. sorry for the different sizes but the hale-bopp one is slightly too big to post at the same resolution as the hyakutake image and i was too lazy to go resize it to fit the board's requirement... :tonofbricks: just visit the flickr page and you can see the larger version.

Hi and thanks for the help on identification. I have quite a few open cluster shots which (sad to say) I have no record of their identities I would like to post . :question:

thanks dave and john. i can solve those images for you or what you can do is join flickr, upload the pictures, and then join the group called "astrometry". if you add your pictures to that group, they will automatically get solved and you'll get an overlay and a comment on the picture giving the details.

This open cluster (loose one in the centre) was taken in 1987 . It was taken at prime focus of my 12.5 inch F-6 Newtonian . It is full field of view 35 mm format so the fov is about 1 degree.
Nice rich star field so summer time milky way I presume any ideas .
Everybody likes a mystery. :grin:

I love this game. I'm 90% sure it's M39. I'm getting most of the stars to match up -- too many to be a coincidence.

I've really been enjoying all of your images.

Here is another open star cluster that I photographed back in and around 1987 although I never labeled the photograph I did some searches which shows it as M-11 ? the wild duck cluster? :question: So if it is M-11 I have a couple of mislabeled M -11 photos posted a while back on page 3 . :confused:

Thanks pfile isn't that a nice big fov for a 75 inch focal length scope ie (59.8 arc/mins *39.3 arc mins)!!be nice to get that now on a modern reasonably priced ccd camera. ;)

This is M 35 and NGC2158. Taken on Konica SR 1600 film . Manually guided (of course) at 700 power for about 25 minutes. The film was hypersensitized for about a day or two . Then it was developed at a 1 hour corner store print shop .

Thanks , excellent work! I noticed that in my 1985 addition of Sky Catalogue 2000.0 I had this galaxy underlined!! :jump:
More to come.

I have found another photo of NGC 7640 which shows that the first one was possibly in the enlarger upside down giving a mirror image.
This photo was taken on Oct 1986 and is a 45 min exposure.
