Mamiya 6x9 Roll Film Adapter
      #1447716 - 02/25/07 11:07 PM Attachment (76 downloads)

Hello all,

Can you help me with this? It is a Mamiya 6x9 Roll Film Adapter that came as part of a BORG 125ED F4/6.4 Astrograph package I just purchased. It looks to me to be some kind of manual exposure film camera and comes with what appears to be an air pump. The previous owner is sending me instructions but I assume it will be in Japanese.

Let me say first I am NOT an imager so I haven't a clue with what to do with this. Frankly, I would like to sell it but I have no idea if it works or of its value. Only thing I do know is Mamiya makes some pretty highend photo gear.

Any comments appreciated.

Thanks,
Rick

I know that the blue thing is a vacuum pump for keeping the film roll flat. That's a mamiya 6x9 astrocamera. there used to be info on it (or something very similar) on the Astrohutech website but it's not there any more.

Dave Kodama images with one I think, and his images are stunning:

The Mamiya vacuum backs work well.
The price of one new is around $800.00 for the film back alone then the adapters vary in cost for each scope.
Unlike a standard film camera you need to buy a separate focusing screen which fits in place of the film holder.
If you decide to use it just remember to turn off the pump before advancing the film to the next frame.

Thanks for the info guys. This is way over my head. I know zilch about astro photography or photography in general other than using a point-n-shoot digicam. Don't have an interest in learning either.

It will cost me too much to convert the scope to visual use so if anyone would be interested in a Borg 125ED F4/6.4 6x9 format astrocamera at a great price please PM me.

thanks,
Rick

Dear fellow film fans, I just wish I was still imaging, that would be a TERRIFIC combo. 35mm film widefields are great, but they're nothing compared to the amazing vistas you get with 6x9.

It's not just that the film is larger, you also blow it up less, which means with good optics (like the Borg), stars are tight tight little pinpoints. Just beautiful.

Hope somebody gets to enjoy this stuff!

Suk

Thanks for the endorsement Mr. Lee. At the risk of being spanked by the moderators, but to save everyone's time, I'll say my price is $3295 for the entire kit that includes the 6x7 F4 Super Reducer and the F6.4 Multi-flattener 1x and all the necessary tube sections and parts needed.

thank again,
Rick
