Eastern Veil in HOO

This is a fun one! I've wanted to image this object up close for a long time. The weather (and a segue into planetary imaging) have kept me from it.

I used my 152mm f/6.5 achromatic refractor for this one. Yep. You can use achromats for (some

) DSO imaging. Narrowband imaging doesn't care that the optics are only capable of rendering limited bandwidth in focus at a given time. I picked this scope up as-new for about 2/3 of the price because the original owner found it too heavy for them. I'd say it probably weighs as much as a 120-127mm triplet, but being a doublet it's still much lighter than my 10" RC or 11" SCT.

I did use a field flattener (TS RCFlat2) with this. It seems to have worked quite well. Measurements of FWHM or HFD eccentricity showed almost perfectly flat results.

I also used the new ZWO OAG-L for the first time, and I'm quite happy with that. Finally, an OAG that produces good guide stars over a large field and doesn't use screwy dovetails!

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.
