Celestron Schmidt cameras

Is anyone using the single shot Celestron Schmidt Cameras on this forum? Or is there a dedicated forum for these cameras?

Yes there are. You might need to wait a bit for them to chime in. It's a rare bird these days.

I bought my 5" many years ago with no real clear plan. Was building a house and planned for a darkroom. Life got in the way and this never happened. the schmidt camera sits in case, not collecting dust, and at this point in life not really sure what to do with it. The use of digital cameras makes me think these are kind of worthless, all my old film camers are not used anymore also really of no value. Looking for some inspiration.

These pictures could inspire you to give a chance to your film equipment . I believe that the scanning is the factor limiting the resolution of these images. If there were more clear nights, I would consider getting a Schmidt camera.

If you can get to a dark site then you might want to give the old Schmidt a try. I have a film holder that does take roll film but I found it too cumbersome and fiddly to use. I prefer the cutting individual film clips which also makes home developing easier to tweak IMO.

Nice photos! I don't have a film holder to hold film cartridges but I plan to make one. I want to use color film too and I can't develop color film chips at home. Black and white is ok but I have to carry a developing tank in the field to put the film chips in it after each exposure.
IMHO the schmidt camera is the ultimate emulsion photography tool!
Kodak gold 200 is cheap and found everywhere. Who needs E200 in 35mm format?

Thanks for the inspiration and replies. I have waaaaay too many scopes and other items I never use and thinking to downsize and simplify. trying to sort out what items are keepers and what I might never use. Life is passing by much too quickly.

Hi,
this is an interesting link for reciprocity failure of various films. Fuji Acros tables are worth study/verification. Giorgo lets coordinate a common Schmidt field test.

Also see this one, although SC with dedicated and custom made Vahrenberg holder are rare.

Also SC can give stunning results on comets (ISON coming):

not to cause a any trouble
I got both 8 and 5.5 SC but I converted mine to use ccd chip
I found cutting film bits and handling them just to much.
but dont get me wrong for those that use film - god bless

I've been using Fuji Neopan Acros 100 for years as an astrophotography film. Other than its lack of Ha sensitivity it is perhaps the best B&W film ever made for astrophotography.

It can be hypered for superior performance or just out of the box. I use it for impressive star field images. It is truly a film worth considering for B&W work. Better than Tech-Pan when it comes to blue-green and yellow-orange sensitivity when hypered.

Hi George,
now you have the cartridge holder for your camera. I wish to find free time soon. This is the major obstacle for me. That's why I tried to find a new owner for my camera. Any way, since I have the camera remounted and a good stock of fine grained films I will contact you as soon as possible for a Schmidt safari. I can help you further in the mounting of your camera.
Clear Skies

"JSO" and "SHOWA" of japan make and made a lot of interesting telescopes and imaging cameras that we do not get to see in the USA.
If you are ever at a news stand look for the "Tenmon Guide" astronomical magazine.
