|The setup Calumet (Cambo) 4x5 mounted atop my classic 8" Meade|
The circa 1984 Calumet / Cambo 4x5 monorail rode atop my old Meade 2080. My friend Danny Spence from Texas gifted me the wonderful Schneider 150mm f/5.6 Super Symmar HM lens. It's fine quality allowed for great wide-open performance. Images were sharp and with little vignetting.
|The 40 minute exposure on Fuji Acros 100|
The 40 minute exposure was adequate at f/5.6, but when developing I thought it best to push 1 stop to bring about some finer details in the Great Rift. Kodak Xtol was used diluted 1+1 and a 13 minute development for an effective speed of ISO 200 was completed in my kitchen.
The film was scanned on my Epson V600 with two passes as this is not a 4x5 scanner. The two images were assembled in Microsoft ICE. I have proudly left the film edge revealing the emulsion tag, basically signalling that this was shot on film!
This area of the Great Rift centered on the constellation Aquila, was done by convenience. It allowed a low enough angle to not stress the system and it was well placed away from trees on my site. You can make out many dark nebulae and star clouds throughout.
I'm very pleased with this first attempt. In time I will do more. There are very few that have attempted large format work in the first of guided astrophotography. I'm glad to have to have made at least one successful effort.
