I have been using the 200mm EF f/2.8 Ultrasonic, and the nifty fifty. I can track as long as the exposure without guiding at those image scales. I have tracked 15 minutes unguided with CCD cams and Pentax SLR lenses.

The monofied DSLRs look like a very interesting path to an affordable large format monochrome camera. However, I what to experiment a bit more using my DSLR to build a synthetic monochrome image by summing the R+G+B data. I did some work with this a while back and the results were encouraging, but this was before I had my camera modified and the red channel was noisy. Now that my camera has the Baader mod I'll try it again. The math says that it should work, but we'll see if it works in practice.

Now all I need is a run of clear weather... like that's going to happen!

You can also mono-fy a QHY8 OSC.

John, who did your mod to your 550D and exactly what kind of Baader mod? I will follow your posts carefully as to your results whenever clear weather sets in.

I bought a brand new D5100 last January for $425 and had it monofied by Jim Chung for $350 if me memory serves me right. under $750 for a mono D5100 is not too shabby

Is there a webpage where you can buy these mono Nikons?
Will BYE work with Nikons?

Clear Skies!

Our own Brent can do it:

Jim can do it also:

BYEOS will not work with a Nikon, but Guylain is working on a Nikon version as we speak.
