Hello folks,

When the Milky Way starts popping up again, I want to do some very wide angle shots.  I have a Nikon Z camera in which I might go and buy a 50mm F/1.8S prime lens.  The special thing about this lens is that it has a short backfocus, and so can only be used with the Z camera and not the mono camera.  I already have a whole bunch of F lenses, mono cooled astro camera + filter wheel, and then a bunch of actual telescopes.  The widest of the telescopes is a Williams Optics GT71, which is 336mm focal length.

Now the nice thing about the F lenses is that there is enough back focus that I can use the filter wheel + mono camera for narrowband.  I used the Z camera for the first few weeks of my learning, but then quickly moved on to the mono camera.  So I don't fully know what the Z camera is capable of.

With all that said, I guess my choice on which to use depends on:

  • Read noise of Nikon Z vs cooled camera
  • Dark noise
  • (also the Z is full frame and the mono camera is micro 4/3)
  • whether any of the wide angle shots are done in narrowband
  • The mono camera + filter wheel can correct for some lens defects, like different focal lengths for each color

Any other factors to consider?

I think the sensor size difference is sufficient for you to go with the Z. Another factor is that if you use Z, you won’t need a computer. In many cases, I find the need of a computer very annoying, especially for wide-angle shots where everything else can be kept minimal. Personally I don’t find narrow-band wide-angle shots very visually appealing, except for deep, high-quality, H alpha, B/W pictures. I am biased, though.
