Yeah, ok, I think I'll just do this from now on.  That interval timer has caused so much wasted time for me.

Hello folks, Setting up my Z6 to do some time lapse for meteor shower.  In that interval timer, I have to set 17" interval for 15" shots.  Otherwise it will start to cut off shots.  (i.e. at 16" ...

I forgot to mention that I already took out the focal plane tilt on the astro camera. I used an artificial star + bahtinov mask. Then a couple of pieces of paper to shim between the camera and ...

Hello, Does anybody know of a place that has the right equipment to align a lens to very high precision? I have an old Nikon 300mm F2.8 that is sharp enough for regular photography on my Z6, but ...

Hello folks, I got a used version of this lens for astrophotography. I think I figured out what most of the knobs and levers do on this lens, except for the second, smaller focus ring. As far as I ...

I use a custom picture control that shows blown highlights as black.  It's almost as good as zebras.

There is one nice thing about this image which is that there is a blurry white wall in the background that can make a good reference for the banding.  If I break the image apart into the R G B ...

With all that being said, one of the great things about digital photography is that you have all the data.  I'm sure these images can be "fixed" by taking out the periodic and repeatable error.

I use the Sigma 105mm F/2.8 macro lens. My opinion: Life is too spontaneous to use manual focus for these things

Even though the Z has a usb-c port, I think it only runs at usb2 speeds

Hello folks, Recently I have been using the Z6 with BackyardNikon (astrophotography program) and trying out its focusing function.  What it does is get a live view thru the USB.  But clearly it ...

The usual response is that the Nikon IBIS is a little bit worse than Olympus.  So expect some fraction of a second at best.

Hello folks, I have a Sigma 60-600mm F mount lens that I use with the FTZ adapter.  In some future hypothetical scenario, I might want to use this lens with a cooled astro camera.  The problem is ...

very delayed reply but I ran into the same problem. Windows 10 made the positive noise when the camera was connected, but it did not show up under explorer for file browsing. Then I remembered ...

You need to test more carefully against a well-defined target with slanted ruler whether there is a focus offset or not. Yes, even the Z with its on-sensor PDAF can have a consistent offset with ...

By the time you're hanging all that stuff off the mount, may as well get one of those $5-600 "wimpy little" 2-axis equitorial mounts with GOTO feature.  (iOptron SmartEQ Pro+ or Explore Scientific ...

Sigma lenses have been exceeding the quality of Nikon F lenses for a while now, although usually heavier.

For small birds, I suggest 500+ mm. The Sigma 150-600mm contemporary is $900, but is a little soft at 600mm.  But many people are happy with it. The Nikon 200-500mm is around $1200 and is a little ...

The lenses have new optical designs and perform better than their older counterparts.

OK, that makes sense.
