Bump

Hi everyone, I am looking for 4x5 vacuum film holders. I do medium format astrophotography but I want to upgrade. PM me, thanks

Uhhh I did not know about the graphite lubricant. I will try that. Thanks again!

Thanks for your reply. Do you need other pictures?

Hey everyone, I have a little problem with my DURST CLS 1000 color head, mounted on a 138. I hope someone can help me out. Lately, pushing the negative carrier in or pulling it out has become not as smooth as before. There is some sort of friction but I can't really understand where. I suppose...

My pleasure! The lens is the 140 mm Macro F 4.5

Hi, sorry for the late answer! These are pictures made with a Mamiya RZ67 attached to an equatorial mount, a device for astronomical observation and astrophotograhy. In a few words, it can be described as a motorized tripod that moves at the same speed of the earth's rotation but in the...

Thanks! And thanks for the information. I don't have time for experimenting now but I will keep that in mind

Really thanks again. I will send you an email with the details of the exhibition. It opens at the end of January in Brussels during the Photo Festival. I am also showing a piece related to my research about colors. You might come and have a look =)

Ahahah it might have been. Thanks!

Hi guys, It was a long day but eventually I made it. I tried again with the Foma paper, mainly because I love its glossy finish, and I solved the issue. It was most likely, as suggested, an underdevelopment problem. I processed the print face up and extended the developing time from 3 to 5...

Thanks guys for the support. I work with several trays and not just one. I make new developer for every session. Since I've started to make this astro-prints, the higher number of 50x60 cm prints I made in one session was 5. I work with 5 liters. So, way less then what recommended on the Ilford...

I constantly agitate the tray and the developer is new every time.

The negatives are fine, the stains change position every time. I don't understand how not developing to completion might create (on the Ilford paper) photos with less stars but with the desired shade of dark gray/black of the sky. And yes, nice talking to you again! =D

Thanks a lot for the fast reply. I normally use Ilford Multigrade 1+9 at around 20°. Just measured the temperature and now is 19°. Developing time is 3 minutes. A few days ago I tried to develop the Ilford paper with the 1+14 dilution for 4 and 5 minutes. I had the same problem, The amount of...
