Going solar with the ASI178MM

Acquisition type: Lucky imaging

I was curious to test a slightly higher resolution camera on the H-alpha filter on the sun.

However, the results were then rather difficult to process. The images had to be massively denoised.
The camera has a small sensor and tiny pixels, not a good partner for bad seeing. The frame rates are very slow, even when using just a part of the sensor, the frame rate increases to just over 40 fps with a setting of 16 bits in Firecapture. So it just takes too long to capture enough frames for a good stack.

Maybe I'm already too spoiled by my ASI432MM, but that was a bit too tedious for me.
Don't get me wrong - this camera is not a bad camera, but the sun in H-alpha is definitely not its field of application. I'm curious to see how it fares on shots of the moon.

The image shown has already been heavily denoised, but no sharpening besides the usual wavelet-settings.
Really not a bad picture, but the path to this result was a bit too time-consuming for me for just a bit more resolution.

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.
