I agree Nightfly, but since I have a dark site to image at, I use 400 and have returned good results.
But, I'm also looking for better film, so I'm going to try the Fuji Superia and the LE. I do enjoy capturing
those red nebulae. Wide Field Southern Summer Sky at Keota

I'd stock up on Ektachrome if you like it. Kodak has stopped making it in sheet form. Anyone have experience with any of the Central European films Freestylephoto.biz imports?

Just scored two rolls of E200 (35mm) at my local camera store. So there is still some of it floating around out there.

There is some E200, Elite Chrome 200, and even Provia 400F on the evil bay. I scored some fresh frozen 400F last month. Get it while you can.

Ilford's HP5 is more red sensitive than any other. Try some! DEv. 8 mins in neat Microphen at 20C.

Hi James:

Have you had any experience with Fuji's Neopan 100 Acros? The spec sheet claims some pretty impressive reciprocity characteristics -- only 1/2 stop loss for 1000 seconds (16 minutes).

Hi Gary,

Sure thing. I have been working with Acros for some time now and it is a suberb film. It is not a great H-alpha film, but it is a strong recorder of starlight.

Here is a sample:

Two of the frames in the above gallery have been selected for the Starstruck exhibit. I hope you get a chance to see the exhibit.

Hi James:

Thanks for the photos -- really great stuff. I think I've seen these before, but somehow didn't notice they were shot with Acros. One last question, while on the topic, what is your view of push processing the Acros. It doesn't seem like you've done so, but I wondered if there was a reason.

Congrats on getting into the Starstruck exhibit. It's a distinction that's well earned!

Gary

Thank you Gary, I've enjoyed myself with these images. I use standard development with Xtol 1:1 for all my Acros work. I have been wanting to try pushing the film and have seen good results in terestrial photography up to ISO 1600. One was with Caffenol-C using Folgers crystals! Pushing Acros with astro work may be different. I suspect contrast could be an issue.

Acros does work very well Hypered as we have seen with the work of Rick Thurmond. The gains were substantial. Acros does well right out of the box of course and seems to continue out to an hour and beyond.

I've been wanting to experiment with some red sensitive films, but have not had the time. Films to think about are Rollei Retro 80S and Superpan 200. Extended red films in the past have been disapointing, but one must be willing to try them! I've done my share and it seems I will perhaps continue this lesson in futility.

I think it is great that you continue to shoot film Gary. I enjoy your new Filmadvance blog. I'll chime in from time to time.

James

Thanks for the info James. And thanks for the inspiration too. I've been shooting Acros 100 for daylight stuff, but was seriously tempted to try some night-sky shots when I saw its reciprocity characteristics. And now that I've seen your work, I'm going to load up the Hassy and give it a try next time I'm under a good, dark sky.

I also really like your moonlit shots as well. So much good stuff there.

(BTW -- drop me a line some time at my regular e-mail address. I have some questions regarding developers that I suspect will bore the pants off CN readers.)

Thanks again,
Gary

Hi OneGear! Nightfly has made a lot of film tests. Look here and here.

Don't know if Konica 1600 Print film is still around, but back in '85 in Arizona it was the hot ticket. I used to vacuum out a pressure vessel and "pump & purge" with a 30% hydrogen with the balance of nitrogen to hyper-sensitize the film. I was going to post a link, but right now I haven't found any ~

Has somebody tried Fuji Pro 160 NS? Its spectral sensitivity and reciprocity characteristics look similarly as those of Superia 100, according to the datasheet.

Fujicolor 160NS has identical specs to 160S, a fine film for portraits. I have yet to test either for astro, but I do have some 160S in the freezer. I'll have to run a roll through and see. I would recommend others to give it a go as well as you point out Michal, the response and specs are similar to the coveted Superia 100.

I'm running low on Superia, but have enough for a few more years of rationed shooting. Last time it was available at B&H in New York, I paid $1.99 for a 120 roll. I now wish I had picked up a case of it!

Now I have to test new films, too. I have the last 4 rolls of E200, which I spare for the case I get under really dark sky. Then I have a few Provias 400F bought expired on Ebay. They don't produce such nice colors as E200 did. Hard times are comming for me.

Michal, I have some good "fresh" E200 I can spare when you run out. I might be able to part with a few pro-packs. I tried some 8 year old frozen Provia 400F and I was not too happy with it as well.

Looking into the Pro160S / NS I am seeing interesting results from folks using it for pinhole photography and reciprocity charts look good even 1 hour out. It will be the next film I test. Thanks for bringing up the topic.

Jim, many thanks, but you will also need them. In the next year or two I can easily get by the Provias I have. I have to watch Ebay for frozen medium format E200. I also have 4 fresh rolls of 35mm E200. Maybe I will have to adapt to the situation and start to shoot throught the telescope with my Practica camera.
