Re: [APML] Film for piggyback.



Hi Donnie:
At the risk of getting flamed by the more fine-grain-oriented members of APML, I would strongly recommend Konica 3200 as the "starter" film, whether it's piggy-back or prime focus. It has good color balance at these exposure durations and the extra speed gives you a chance of picking up some deep-sky stuff as well as stars. As soon as you have enough results to whet your appetite, you can start shifting down in ISO and up in exposure duration. To Konica Centuria 800 or Kodak Supra 400 (or 800) for example. You can get the 3200 Konica from B&H (on-line, NYC) or Lumicon, the slower speeds from B&H. If you're already grain-intolerant, you may want to start with the 800 or 400 speeds. I found that when I started out (with a poor mount), I really needed the extra speed to get satisfying results, so the 3200 Konica was really helpful.

Subject: [APML] Film for piggyback.

I searched the archives and found no conclusive answer. Is Supra any good. Reading through the archives I saw that Tony was not fond of it. Right now--to get started, I really need to stick with prints.
 
I have an older SRT101 from Minolta. I am going to "try" piggyback wide-field. I am encouraged by the beautiful results of others. Of course it is also less demanding--guiding wise.
 
Which color negative film is best for 5-15 minute exposures, with a fairly dark country sky. I spoke with the operator of our local 1 hour lab today. We talked for a while about the types of shots I would be bringing in to have processed. They have agreed to work with me. I know its not the best place to take astro film--but for a start I believe it will do.
 
Anyway, if anyone can offer suggestions as to what works and more importantly--what works now, I would be grateful.
 
Thanks,
 
Donnie
