Rosette Nebula

Currently I am in process of collecting wide-field data around Rosette from my Bortle 8/9 area. With the moon polluting the skies for the next two weeks or so, the project remains unfinished. I was quite surprised with how rosette nebula came out when stacked 6.6 hours data to check. So I just drizzled the data on APP and did a massive crop to isolate Rosette.

Since Rosette is at the top right corner of my main image, oblong stars from the corners has plagued the stars at the centre of rosette. It could be result of aberrations from my lens or there is a tilt issue between my camera sensor and the lens. I think it is the latter. My camera/lens mounting system is introducing the tilt between the camera and the lens. My guiding has been okay with normal RMS error around 1.2 arc seconds. I am in process of investigating this issue.

In any case, till the wide-field is finished, this one deserves to be uploaded separately.

Title: starless

Description: I think the starless version looks better. For the first time star shapes have really started bothering me.

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.
