Straight EAA capture - saved as seen in SharpCap 4.1. This one was surprisingly faint with the Askar130PHQ. There was a moon in the sky and IC 433 was only about 30° above the eastern horizon (my worst view of LP). Still, the L-Ultimate was able to capture some OIII along with the H-alpha.

This SNR is one of my favorite DSO's. Past experience has shown that this one is pretty bright and that's what I expected with the Askar130PHQ. Somewhat surprisingly, it was very dim and was barley visible after even 5 minutes with a fairly aggressive stretch. The L-Ultimate is proving to be a winner for pulling out the fainter OIII bits though - much better than I could do with my L-eNhance. I get hints of the Veil nebula from the streamers on the western edge (the left in this capture) near the bright variable star Eta Geminorum (Propus, 3.29m - 6.15m).

For comparison, I captured this view with my Askar FMA180 + ASI294MM-Pro + 7nm Optolong H-alpha last year (12/2022).

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.
