Robert Moses State Park NY - 8/13/22

66 x 300" - 15 Darks - 100 gain - Dither every sub

Guiding .2 - .5 RMS guiding - Best guiding ever so far. Almost never got above .5 RMS - .35 RMS average all night

This image was taken under a full moon high in the sky! The Antlia ALP-T Is an amazing filter. I wasn't sure about it when I started my run and was almost gonna remove the filter after a couple of subs, but decided to keep it. I've never used anything other than UV/IR cut so I'm used to seeing a much more starry starfield. 300" subs was also something I had never done before but since it was narrowband I knew I'd need longer subs than my usual 120". A lot of doubts and praying, but the Antlia ALP-T filter performed beyond my expectations. I would not have been able to get an image with the full moon beating down on me without it. DSS showed only .96 - 1% skyglow per sub using 5 min subs from a bortle 5 site under a full moon at its zenith... Amazing

I love this filter. I have never had an image almost be postable after 7 operations in photoshop. I don't think I'll ever shoot an emission nebula again without it.

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.
