Hi everyone, I have been printing on the same enlarger, an old Beseler 23cii (universal color head model) with the regular Condenser Head. I also have a newer Beseler 23cii enlarger. Until I can get a diffusion or cold head (which are the same right?) for it, I'm working with this. I have noticed since I started Lith Printing an issue I can't seem to fix - where edges of the image are slightly out of focus. When I sweep my grain focus-er across the easel (VTI-1400) or base, as I near the edges the image won't even shine through the focus-er lens, if I tilt it I can get the image to reflect through. This occurs on 2 different grain focus-ers. When I get the center of the image grain tight, as I sweep from side to side & front to back the grain softens, even when the lens is stopped down. I have tried just about everything I could think of & have read about to try & resolve this problem. The strange thing is this happens on both enlargers! I use a Negetrans negative carrier, but have also tested this on the regular carrier as welll. It did this with the old 50mm Schneider-Kreuznach Componar 4.5 lens, I wanted to upgrade so installed a 50mm Rodenstock Rodagon 2.8 lens in it's place, having to use the lens board from my other enlarger as the old lens had a 25mm(I think?) mount. Here's what I've done to try & resolve this: I installed a new baseboard to make sure the surface is level. I adjusted the lens stage alignment & made sure the Condenser assembly is level with the board. I tried adjusting the Condenser assembly (shifting it from side to side), but nothing fixed this problem. Trying all these I put the old lens on as I adjusted everything to see if the problem was fixed. The newer Rodenstock Lens is different than the old el-Nikkor hazy lens - when it is tightened down to the board, the top of the element sticks up 5mm or so above the board. Can anyone help me out with what is going on? I've read threads about adjusting the lens-board, but the screws holding the brackets in its place don't shift the lens board at all. Ive tried loosening one side or the other, & tightening them down don't shift it at all. Any responses would really help. I've spent the last couple weeks driving myself crazy trying to fix this! Do I need a different lens board? I don't know why I haven't joined this community until now, I have been gained so much knowledge over the years from everyone who is a part of this fantastic community, I can't wait to help answer questions I know the answer too.
