Burning orange – first attempts with the sun in h alpha

Acquisition type: Lucky imaging

My first attempt to capture the sun in H alpha.

At first it took me quite a long time to find the right working distance for the Baader SunDancer II. Then the image was sharp in FireCapture, but the heavy wind and miserable seeing often smeared the image. When I tilted the etalon, the structures came out better and better. So the SunDancer was not well adjusted. I'll have to make up for that at the next opportunity.

Overall, I am highly satisfied with the performance of the instrument, even if it requires some time for optimization. But that's only at the beginning. Once I know the right settings, it should run smoothly. And for a first picture under adverse conditions, I'm reasonably thrilled.

Mosaic of 9 individual images. In each case the best 60 of 2000 images stacked with Autostakkert 3 and processed with Affinity Photo.

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.
