    A hot-take on Siril for astrophotography.

    Over the past 2 years I have been slowly learning the craft of astrophotography without a telescope. A critical piece of the puzzle is the software tools you use to process the images you take in camera. You won't be getting desired results just using Lightroom or Photoshop or whatever other...

    Another astrophotography oportunity on 12-21-2020.

    If you have a star tracker, it will be much easier, and perhaps a telescope is needed. Saturn and Jupiter will converge in the sky, and be at their closest to each other on the 21st. In North America, Jupiter and Saturn are in the southwest sky right after sunset and setting an hour or so...

    Just a heads up for the early part of November 2020.

    About the 7-8 of November Mercury will be in the sky near Venus before sunrise and about as high as it will be over the horizon. Stellarium is showing this as a possible photo-op. These screen-shots are frozen at about 5:45 am at my location and you would be smart to check in Stellarium with...

    Tried out a different approach in post-processing this pic.

    Andromeda Galaxy, I shot this in July. The normal procedure for an astrophotography subject like this is to use software to automatically align and stack a few dozen images which are then flattened into a TIFF. I use RawTherapee and GIMP for the post-processing mostly, but I do have Luminar4...

    Triangulum/Pinwheel Galaxy

    Andromeda Galaxy has been the popular subject, but how about Triangulum Galaxy (Pinwheel Galaxy)? It is the 2nd closest galaxy to us. And it is not that far away from Andromeda, you just can't see it with unassisted eyes. I did this at the end of taking a series of Mars and Uranus. Battery was...

    What kind of USB connector is that on the D750 body?

    My D7000 uses the older standard Mini-B. I guess I assumed the D750 was a Micro-B like most every phone or other portable device with USB. When a micro-B cable would not fit, I ordered a USB type C cable from Amazon. It arrived today, connector too big. What is that connector? I want to tether...

    One night, 2 camera bodies, widest angle to longest telephoto.

    Weather was perfect this past 11th of August, which was the peak night for the Perseid meteor shower. I also decided to target Jupiter and Saturn the same night. On a tripod pointed north: D750 + Sigma 20mm f/1.4 with the intervalometer set to take a 15 second exposure every 20 seconds. I was...

    Hello to all from Madison, WI area

    I am Chris, a hobbyist photographer although I have taken money for an event or 2 over the years. I took a photography class in high school way back in 1982. I did not actually acquire my own film SLR for another 15 years when I picked up an entire Minolta XD-11 kit at an auction. I bought a...
