I just completed the first of three projects whose data was captured during the nice stretch of weather we just had between Aug 2nd and August 4th. This is a 12.8-hour integration of SH2-101 - The Tulip Nebula. This was taken on my Astro-Physics 130mm platform with the ZWO ASI2600MM-Prop Camera.

Description: There was a weird line that bounded the blue area in the tulip. I'm sure how it got there but I was able to fix it.

Description: I was bothered by the rendering which seemed to emphasize the many small stars in the field. I have seen other examples of this when you are dealing with a very rich starfield. While not an issue when you zoom in, it is an issue when you see the whole frame rendering. So I went in and create a small star mask and did a light convolution operation to de-emphasize those stars. I think I like this version better.

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.
