First H-alpha Solar Images - Prominences (JDJ)

First H-alpha Solar Images - Prominences

Acquisition type: Lucky imaging

First light with my new Lunt LS50Tha H-alpha solar telescope went as well as I could have hoped. I was able capture the Sun, focus, tune the etalon, and find a nice prominence. After some initial visual observation, I reconfigured and hooked up the ASI 290MM and was able to capture images of the surface and prominences. Really looking forward to learning my way around solar imaging...

Imaged with a Lunt LS50Tha, Baader UV-IR cut filter (not sure I needed that), and ZWO ASI290MM. Imaging train was configured to give me ~F/7. Image capture using Firecapture (see below for exposure settings). Stacking in AutoStakkert3 (best 25% of 500 frames). Processed in IMPPG (LR deconvolution, stretching) and Registax (wavelets).

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
