I read this many years ago and have been using it with great success. Take your trans./slide and copy it or rephotograph it using 100ASA print film then go and have it printed. The colors almost jump off the paper. There is a great amount of contrast generated in the dupeing process that brings out a lot of faint detail in astrophotos. Its a little trial and error as far as getting the proper exposure with the dupe. The only equipment I use for this is a slide dupe lens/kit, light table, camera. After I photograph my slides I take the film to get it processed but not printed ($2.00). I then can see what exposures worked when I duped the slides, and can decide to re dupe at this point. If the negs look good then I can go and have the negs printed. I use a Kodak create a print machine for all my printing. (I think its the last working machine in the country). You can also get them printed at any store that has in house minilab...so you can talk with the lab person in order to get your prints done correctly. This process also increases grain but I am very happy with 8 X 10 that were originally shot on E200. Here is 2 prints I did today that I shot last month on E200 through my C-11. ( see next post for more info)

Hi All, I want to run my ST4 from a 12V battery but this is the cord I got with the system. I am not a electronics person so I am asking what do I need to do to run it from a 12V battery power source. Here is a photo of my power supply cord.

Thanks

I used a C-14 with optec .5, ST9E. Single 10min. I got down to around 20th mag. Processing is rough but I'm learning...

Here is a pair of 3 minute images co-added and processed in CCDops. The odd background pattern is misaligned filter wheel. C-14, Optec .5x, ST9E

Here is a image I took Friday night At the Veen Observatory with a ST9XE through a C-14 working at f/5.5. 480 seconds in each channel (LRGB)

Joe

Here is a image I got on Friday just after it got dark enough to get some data. It was just above the trees. Each channel was 300 sec (L Ha/R, G B) I combined the RED and Ha data into the R channel. I used a C-14 @ f/5.5 with a ST9XE.

It was too low behind the trees to photograph when the closest approach to M57 happened but I did observe it visually. This was shot about an hour later using a C14 with a ST9XE. This is a 30 sec shot and the comet trailed just a tad.

The Star Queen Nebula is an old discription of this object. Anyway here is an image I took last week and finally got it looking ok. I tried for Ha but it clouded up just as I opened the shutter. Data is 15,1,1,1. I used a C14 @ f/5.5 with a ST9XE. I used 1 min exposures for the Lum so I wouldn't get any blooming on the brighter stars. Also the many frames also smoothed out the gritty look that the ST9 gives because of the 20 micron pixcels.

Here is another shot from the 28th of June. The data for this was 6,1,1,1. It is really interesting how far out the stars go. I read somewhere that this is one of the oldest globular clusters in our galaxy. These guys are tough to process and still look natural. I used DDP filter 5 times before I got the right amount of resolution across the core. Also I have a goofy gradient in the upper corners because the desiccant needs to be refreshed.

I took this in 2003 but just got around to copying it onto digital. I took this with my C-11 @ f/6 on E200. Time was 20 minutes. I copied this with my digital camera so its not nearly as good as it would have been if scanned. I got the size a bit small so it uploads faster.
