NGC 3628 Hamburger Galaxy (Part of Leo Triplet) (Roger Menard)

NGC 3628 Hamburger Galaxy (Part of Leo Triplet)

This time of year one of my favorite objects is the Leo Triplet consisting of M65, M66, and NGC 3628. Two years ago I imaged the Leo Triplet. Since Leo is in a good position in the sky, I decided to do justice to each of the three galaxies in the Leo Triplet.Last night I started with NGC 3628, also known as the Hamburger Galaxy. It is also known as Sarah's Galaxy.NGC 3628 is an unbarred spiral galaxy that was discovered by William Herschel in 1784. It has a conspicuous broad band of dust located along the outer edge of its spiral arm.Last night was clear but wind gusts. Also the Moon rose about midnight. In order to combat the wind, I install a wind barrier on the West side of my observatory. This helped but I still lost several images due to high gusts. I starting imaging around 8:30PM and concluded around 3AM. I was able to acquire 173 images (2 minute subs), of which I found 160 to be usable.I imaged with 11 inch SCT and ZWO ASI2600 OSC. I used ZWO ASI290 attached to SVX130 refractor for autoguiding. As always, I used SGP4 to manage all of the imaging hardware. NGC 3628 transited the meridian at about midnight.I generally try to check on the status of the meridian flip just to make sure everything functioned properly. For a successful meridian flip, SGP has to know when to flip, control the mount to flip, turn off autoguider, once flip has been completed re-platesolve to match pre-flip framing, restart autoguider, re-focus, then start taking images. There is a lot that can go wrong (but I have found that SGP4 handles the situations). Last night I did not wake up until much later and found that SGP4 managed everything perfectly. Attached is the image I took a few years ago showing the Leo Triplet followed by the processed image of NGC 3628.

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.
