We have a new-to-us Celestron C9.25 Schmidt-Cassegrain OTA and as everyone knows, the front corrector plates on SCT’s are extremely prone to dew. So we have had an external strap…

Winjupos. A word that strikes fear into the hearts of image processors. You may have heard of it for its ability to “derotate” a series of planetary images, such as…

Out last evening (Thursday Nov 7) imaging Saturn. This is the best image of the best 10% of 10K frames exposed at 18ms. Saturn was only 35 degrees in altitude,…

One of the best events of this apparition, a shadow transit of Ganymede from 20241103 02:39 UTC ending at 04:35, or 126 minutes. I completed 34 imaging runs of 180…

From the overnight of Thursday/Friday 2024 October 10/11 about 40km northwest of Kingston Ontario. This is from the formerly known as allsky1 camera system, now aimed to the north and…
