Sun in white light and hydrogen-alpha

This is some practice imaging and processing on the sun in white light (left) and hydrogen-alpha (right).

Imaging both in the same session gives a nice opportunity to compare the sunspots and features. The sun was really active that day, and the sunspots were large enough to see through eclipse glasses.

We're getting ready to live stream full disc white light and H-alpha during the April 8, 2024 total eclipse from Bloomington, IN USA. We'll plan to capture 4-6 TB of video between the two scopes throughout (partial-total-partial) for open sharing with the community.

White light image:
* ZenithStar 61ii with 0.8x reducer
* StarAdventurer Pro
* Thousand Oaks full aperture white light filter
* asi585mc pro camera, capturing 3473 frames with FireCapture
* postprocessed in Autostakkert (stack 10%, 3x drizzle) and photoshop
* Rotated to match orientation in SDO

Hydrogen-alpha image:
* Lunt 60MT single-stacked scope
* cem26 mount
* asi485mc pro camera, capturing 1000 frames (stack 10%, 3x drizzle) with FireCapture
* Postprocessed in Autostakkert and photoshop
* Flipped, rotated, and scaled to register with white light

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

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.
