Messier 13 (Bradley Watson)

Messier 13

Link: https://bgwphotography.com/messier-13

I have been sitting on this data for a while now, 1) because I have had very little time due to work and increased travel, 2) buying a new house and 3) not overly happy with the data, but am posting anyway. As I am still wrangling with my RC I think its always good for others to know some of the pains we go through in pursuit of perfection.

I imaged M13 as it was high in the sky and clusters seem to be good tests as they often have a good concentration of stars across the field enabling good assessment. Seeing had been pretty poor across both nights with very thin levels of high altitude cloud that was barely visible but was having an affect on guiding, so had to throw out quite a bit of data. Although the stars are round they are soft and bloated and am thinking that roundness is a function of bloatedness and not necessarily good collimation. In anycase the stars are fairly uniform across the field.

Since imaging this I have adjusted the distance between the mirrors to give the correct focal length but due to shortage of time, have not been able to test the scope, hopefully soon but we'll see. If this does not work, I'll try a tilting adaptor (I am trying to not buy a laser collimator that costs far more than the telescope itself). The good thing about this story is that we are looking for a summer house and a criteria agreed between my wife and I is that it needs to be in a pretty dark place (it took a while to explain darkness), so hopefully I'll be able to escape the city and still be comfortable.

Comments are most welcome as I am always looking for good advice/learnings.

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.
