After about 30 years I have renewed my love of astronomy. I feel like Rip Van Winkel!!.
One of things I have done is dusted off my old photos and scanned them and enhanced them as best I could.
This photo is on TP 2415 hypersensitized in forming gas. Photographed with a 12.5 inch F-6 Newtonian and an Olmpus OM-1 camera. Exposure time was 45 mins approximately.Mount was a homemade HEAVY fork mount with a 12 inch Thomas Mathis worm drive.

Welcome to the film forum. So glad you shared this wonderful image. We'd love to see more. Are you still interested in shooting film?

Welcome back to astronomy. Grab your film gear and jump in. Lots of films for the 35mm colour or B&W to use. Please do post more blasts from the past.

What a great classic image. I'd like to see more. I'm a big fan of hypered tech pan, being perhaps the last practitioner of the art.

I have got lots and lots of pictures to share using Tech Pan ,and colour of the day as well as some spectroscopic 103 a-f ones as well.
Here is a Cygnus loop picture again using TP 2415 on a 12.5 inch f6 homebuilt Newtonian with homemade off axis guider.

Here is one more . This M-33 photo was taken on Oct 24 ,1982. It was exposed for 85 minutes at F-10 on a Celestron C-8, off axis guided .I used 103a-f spectroscopic emulsion that was hypersensitized in forming gas for 29 hrs@35psi and 30 degrees C.
Loved that C-8 and so I now own a Vintage 1982 as well as a Nexstar 8 se and hopefully soon a CG-5 mount( on order) I am back in business!!

That's an impressive photo. You really worked for that one, 85 minutes at long focal length, and it was a long hypering time too. What sort of hypering setup did you have?
I use a Lumicon that I've had since about 1999.

My hypering set up was homebuilt . It included a welded steel container with inlet and outlet valves which had the film in it wound on a processing reel, a gas storage cylinder and pressure regulater , a heated box with thermostat.Here is another photo taken with my 12.5 inch of M-13 taken on June of 1984 on Fuji 400 which was hypered for 86 hrs in the above described system exposure was for 30 mins.

John, these photos are of the kind and era of those that inspired me in my early days. I swear that M-27 shot was on the cover of Deep Sky, Circa early 80's.

The patience and dedication to produce these works cannot go without notice. This is why there were so few astrophotographers in those early days.

So glad to see these posted. Feel free to jump back in, we'd love to see something new after a long hiatus with the camera and scope.

John,
How did you learn the technique? Did you have a copy of Wallis & Provin or a good group of people around?

Nice shots, welcome to the group.

I have slowly been taking my 35mm negatives in and having them rescanned to CD. I have my old Comet West 1976C that I am slowly processing out the dust and scratches.

Thank you for your kind comments. I actually learned my hyper sensitizing techniques by combing Sky and Telescope magazine.
Sure has been a lot of changes in astrophotography and amateur astronomy in these past 30 or so years.
Here are some of my favourites 1) Goto mounts alt-azm as well as equatorial 2) web cams for solar system photography (great!!!!)3 ) Video cams for live deep sky views and with the goto mounts and the video cams I think I will be doing some armchair viewing here in Alberta in my den with fireplace on this winter.4) The internet and forums like this one.
Here is an Orion Nebula shot I scanned off a 5*7 .

WOW, finally a LF shot. Was that a tri-colour? I'm itching to do some LF myself, but finding a sheet film is something else. I've settled on trying Astia, which is now discontinued, but still some sheets available.

That is some incredible FOV. What a perspective. I could go on. And I will - inside voice now.

The Orion nebula shot was on 35 mm Konica SR 1600 colour print film which was hyper sensitized 15 hours exposure was 15 mins. The picture was developed and printed in a machine at a local photo developing store no (special processing). The 12.5 inch f6 telescope gave about a 1.3 degree field on 35 mm film.

Late to the party as usual, but let me add thanks for posting your shots. I need the inspiration as I have the TP, but need to get moving with it. This year's poor weather isn't helping any.

Nice photos. I think this is M106 and NGC 4248?
