I want to share this website containing the excellent astrophotographs taken by the late italian amateur Aldo Radrizziani. Great work! Many taken through his schmidt camera on unhypered(!!!) technical pan! Post Extras:       laconicsax super member Reged: 10/05/10 Loc: Portland, OR Re: Excellent schmidt camera work on b&w!

The detail and contrast of the large (4x5) negatives is amazing. It is this type of masterful astrophotography the world will be without from now on. Makes me melancholy.

We now have equipment - lenses - scopes, but no films left that will record the reds in colour or B&W. I'd be shooting B&W constantly if I could get results like this. igor Post Extras:       Giorgos super member Reged: 01/14/11 Loc: Athens, Greece Re: Excellent schmidt camera work on b&w!

Ilford Delta 400 can be used right out of the box too I guess... Ilford 3200 has also nice red sensitivity but the grain is huge! The prints look like coarse sandpaper...

[Re: mitsos68]       #5317075 - 07/14/12 08:15 AM Edit   Reply   Quote Quick Reply   I agree. The conversion of an optical system designed for a very wide field on a very large piece of film cannot be replicated. Attempts to do so do not provide the intended wide-field image intended by the design. If you have not ever seen the large negatives shot with the worlds largest Schmidt Cameras, prepare to be overwhelmed. http://www.flickr.com/photos/deepskyvideos/7175876651/ Post Extras:       TechPan6415 member Reged: 07/29/12 Loc: Aspen, Co Re: Excellent schmidt camera work on b&w!

I have hundreds of rolls of the last batches of TP in both 35mm and 120mm in deep freeze that I use primarily for fine art, but it would be fun to do some Astro work with a bit of it...Hence my username...

JSO in Japan made many sizes but they dont show up much in the USA. Post Extras:       Pages: 1
