Solstice imaging experiment - M17 short time

This is a single image of M17, taken June 22, 2020.

We don't have much in the way of astronomical dark at my locale at this time of the year, as the sky remains at various shades of blue until midnight, and my window is from midnight to about 2:45 am.

I was busy earlier this week during new moon and took images on a number of objects.

Below is an experiment to have a look at M17.

Scope: SV 70t with SV FFFR

Mount: Unguided with HEQ5

Camera: Canon 60D

ISO: 800

Time: 1 x 180 sec

f 4.9

Filter: Optolong CCD CLS for LP reduction

Processed slightly (contrast and some saturation) with photoshop 2020.

No darks, flats, bias frames.

Some egg-shaped stars, but well..., its unguided. 🙂 I think I could do better with a less "perfect" balance and make the set up slightly East-heavy.

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.
