There are two 'first' in this image. I have modded my Canon 40D for full spectrum and I have got the new scope - my first apo refractor. As of now I don't have a UV/IR cut filter which is why there are bloated stars in the image. After going through scores of webpages and forum posts I thought a triplet or a quintuplet would be great. I had been oscillating between Sharpstar 76EDPH and 65PHQ. However, due to some issues or the other at the vendor side the order could not be placed. Then my vendor informed me that a customer of his has returned a new William Optics Zenithstar 73 and would I be interested. It was cheaper (wayyyy cheaper). Then a timely review of doublet vs triplet vs quintuplet was released by Nico Carver on his channel Nebula Photos. I think good sense prevailed and I agreed to purchase Z73. The next day the vendor brought the scope and handed over the scope.

This is my first imaging telescope so I do not have much to share. Thanks to all the experience of imaging with Samyang 135 mm, I was ready to image with this scope within couple of hours of its delivery. On an otherwise very cloudy day, the sky got clear for one hour and I just fired away. The scope was a breeze to use. Focussing with Bhatinov Mask was a joy. I used SIRIL's GHS for the first time and I guess it will become my main tool to stretch images from now on. Lot to learn there.

The next upgrade plan is a dedicated camera. Lets see when that happens.

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.
