Preliminary veil nebula, tri-color tech pan new
      #3236929 - 07/24/09 10:49 PM

Here's my preliminary shot of the NGC6995 portion of the Veil nebula. I used three sheets of hypered Tech Pan with red, green, and blue filters from Hutech. I scanned them on my cheap scanner and combined them and touched them up just a little in Photoshop. Next I'll get better scans and do some more careful image processing and report back.

Great color saturation. That's a great photo Rick. I can't wait to see the final cut.

Very nice image. The colors are a lot more vivid than what you get with a DSLR.

Hi Rick,
You have a good start with this image and I am certain a better scan will make a big difference. What format are you shooting? Really nice medium format scanners can be had pretty cheap these days. My recently posted shot was scanned with a Polaroid Sprintscan 120 that I picked up for a song (compared to the going price before digital cameras got off the ground!).

Hi Robert,
For my tri-color hypered tech pan shots I use 4x5 sheets. I like being able shoot a single sheet then develop it the next morning to see how it came out. Also, I think it's very easy to hyper that way. My scanner is an Epson 3200. The service I use for my scans has a drum scanner and most importantly, someone who knows how to use it.

Thanks. The filters I use are interference filters with very sharp cutoffs, so there's no crossover. Then once I have combined the three exposures I set the profile to BestRGB. That's what really gets me the color I want.

Awesome Rick. I love the red and green filaments, especially the almost fork lightning ones at center. Highly detailed. It will be interesting to see your final results. Top notch!

Thanks. That's why I've been thinking about taking this one for so long. My E200 picture of 6992 has the striking red, but doesn't have the green. Also, I wanted the detail that only Tech Pan can deliver.

Rick - reading your words in the AP forum, and seeing your work, gives me an insight into your passion for what you do. The enjoyment is obvious, and gives me a lift as well. I hope you are able to find enough film to keep going for many years to come. It's what we do for our own enjoyment that really matters.

Igor, indeed I get a great deal of enjoyment thinking about and doing astrophotography. I like the problem solving, the science of the film and of the objects, and especially the darkroom work. It is quite a break from the computer work I do for a living.
I'm not looking forward to running out of film. Then I'll probably get a HyperStar converter to stick on the front of my telescope and start taking wider fields on some sort of digital camera. Maybe by then there will be a camera that catches as much information as film and doesn't cost $13000.

$13000 will buy a lot of film!

yes, but only if the film is still available!
I have about 30 sheets left of Tech Pan, a few 120 rolls, and now 8 rolls of E200. I think after that, I'll need to get a digital camera. I generally use 4 or 5 sheets to get three good images to combine as a tricolor image. So I have a few objects mapped out for the next two years or so. I might be done with shooting E200 through the telescope, so now it will be for piggyback and tripod shooting.

We are all similarly in the same boat to some degree with regards to film. There is still E200 available from some suppliers. Might be worth grabbing a few more rolls.

I'm looking at Ilford HP5+ B&W in 120 format to use on some dark nebulae. It apparently has excellent red response characteristics, and at ISO 400 has good grain structure from what I have been reading (R. Reeves). Might be worth consideration along with Fuji Acros 100 which apparently has great reciprocity? Don't know about hypering these films, however.

I'm not giving up hope, however. I know things change, but sometimes it can work out in different ways. Many hobbies - like model trains, old car collectors, go through this as well. But then, someone comes along and says - I can make a business from supplying NOS parts etc. Just wondering if this might happen (wishful thinking) with an astro film.

I continue to ask everyone to email Fuji - Rollei - and to state our case. Maybe one of them will listen - just maybe. We need to get behind this to have any chance. In the meantime - looking forward to your future, treasured work.

Igor
