Astrophotography

Here I offer a collection of astrophotos. Feel free to use them as you'd like.

Sun

A single frame from the Coronado featuring exhaust from an airplane that passed just a few frames before. Unfortunately I was unable to catch it. A few sunspots are visible, though the etalon was not tuned, so no additional details are visible. Taken at the Fuertes Observatory on January 21, 2024, using the ZWO ASI1600MM Pro with ASICap.

A 50-percent stack of 100 frames, stacked using AS4 and colorized using Preview. Taken using the 90mm Coronado, with the etalon tuned. Unfortunately, the cold made it difficult to spend enough time focusing, so the image is not as clear as would be desirable.

A 50-percent stack of 100 frames, stacked using AS4 and colorized using Preview. Taken as a part of a series of several hundred frames taken over the course of an hour. I have yet to process the others, but hope to make some sort of animation out of combining them all. Focused better than the last this time! Taken at the Fuertes Observatory on February 7, 2024, using the ZWO ASI1600MM Pro with ASICap.
