Lunar crescent 15/8/2018 Brisbane Australia

Taken with my Canon EOS 60D and Saxon 6" Dob. Single shot.

The focuser on my dob doesn't let me bring images to sharp focus due to a lack of inward focus. So, I removed the 2' focuser insert that comes with the dob (it's a really messy system imho) and directly inserted the camera + t adaptor into the raw focuser, with the focuser racked all the way in. It looked close enough to sharp to my eyes via the camera's viewfinder, but upon closer inspection the RAW image, it's slightly soft. I had to hand hold the camera against the focuser to try and keep it square to the imaging plane, whilst trying to frame it too, since at the focal length of 1200mm, the moon's image was a bit too large to really work with (bonus, I don't have to crop the image I guess).

A sloppy method of making something kind of work, that wasn't going to ever work in its default setup.

I know it's a dob, and you don't tend to image with a dob (for a variety of reasons), but it would be nice if manufacturers made sure that their focuser can come to focus with a normal DSLR...it's not much to ask imho.

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.
