Messier 2

Messier 2, also known as NGC7089 is a globular cluster in the constellation of Aquarius. It is one of the largest know globular clusters and was discovered in 1746 by Giovanni Domenico Maraldi. It lies approximately 55000 ly away and is around 174 ly across.

This is the first deep space image that I have taken with my new scope, an AD250 from 656Imaging.co.uk. Unfortunately the image does not do the scope justice as the mount (although doing a very admirable job) was struggling to keep the stars as tight as I would like at that focal length. It was something that I was expecting and prepared for. I was just to impatient to wait for the new mount. I also need to tweak the camera to get the sensor flat to the field. All the usual tweaks that you need when getting such a precise piece of kit running at its best. That said the image is way better than anything I have ever done before at that focal length. So far I'm delighted with the result and the best of part is that I know that it's going to improve a lot more.

Description: Cleaned up the background, tweaked the sharpness on the stars and pushed the curves and saturation a little more.

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.
