This is my first serious project with the TS 60/360 Apo and the SmartEQ Pro mount.

Acquired over 11 nights (June 8, 22, 25, 27, 28, 29, 30 and July 1, 2, 3, 4) from the top of my building. The sky was exceptionally clear on July 2nd. Best sky in 9 months.

The same night, the cockroaches dwelling on the top of the building (which I didn't know existed) decided I am basically harmless and started just going about their business without paying any attention to me.

I hate cockroaches, but I stayed because it will probably be another 3-4 months until the sky is so clear in the Athens region.

I think this photo is at the limit of what one can image from suburban athens, this low in the southern horizon. It would probably llook seriously better from a dark location which is where I will be at the end of the month (although I will do more demanding targets there).

The SmartEQ Pro mount performs MUCH better than the Star Adventurer and GoTo is a feature that saves *a lot* of time. However, I would say it is a bit inconsistent. Sometimes I have up to 5 perfect subs in a row. Some other times more than half of the subs will have serious star trails while the other half is okay. Not sure why.

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.
