I have old Meopta Opemus5(6x6) enlarger. I have both b/w and colur herad for it. Enlarger do have condensors, but non changeable. So, it make 35mm enlargments like cropping off negative 6x6 size... I have Anaret 50mm f4.5 and Anaret 80mm f4.5 lenses. Now, I am not happy with 50mm lens. Yes it is cheap toy, with only four aperture blades. I am thinking to replace both lenses with respective Rodenstock Rodagon or Schneider Componon-S. My questions are: How to chect alingment of my enlarger(without test negative), recommendations for other enlarger(up to 6x7cm) and if anyone has good experience with Opemus5 enlarger any advice will be werry welcome.

Thanks, Haris</td></tr></table><span class='postcolor'>
First, I am not familiar with this enlarger so I cannot be specific, but I have aligned several Omega and Beseler enlargers and I think the method which is cheapest and gives the best overall alignment is the double mirror method.

Get two mirrors of plate glass if possible. Hardware stores usually sell these as tiles. I got mine as scrap from the local glazer. Make sure there is sufficient overhang to insure good contact with the enlarger parts. Remove an approximately circular portion from the "silvered" surface about 1/4 inch dia. It is a good idea to stick one of those hole reinforcement "doughnuts" (used on punched paper) around the opening on the mirror side.

You may have to remove your light source for the following. Place the unmodified mirror on your base plate, or beter still, your easel. Place the other on the negative stage, mirror side down and centered as well as possible (no biggy). Peer down throught the hole and you will see a number of receeding reflections of the "doughnut". Make your appropriate adjustments untill all the images align and you see concentric "doughnuts" to infinity.

If you have trouble eyeballing the setup, you might wish to use a third mirror to get an easier perspective on things.
