Hickson 44

Tucked away in Leo are a number of well known multiple galaxy groups. The one

presented here is Hickson 44, otherwise known as Arp 316, or even the NGC 3190

Galaxy Group.

There is a slight cautionary tale to be told here. I had been noticing that my

main mirror had been getting increasingly 'dirty'. I am a little allergic to

removing the mirror and cleaning it for obvious reasons and put it off, and off,

and off! Well we get very damp conditions here in Weymouth and dust and dirt

makes very handy condensation sites for moisture. After I'd finished this

imaging session I had a quick peek at the state of the mirror. Horror upon

horror, the whole thing was awash with moisture and every sort of muck

imaginable. I've no idea how the image turned out this well actually. Anyway, I

straight away removed the main mirror, took it indoors and dried it out. Next

day I very carefully washed it off and dried it thoughourly, before storing it

away in a nice dry airing cupboard. It looks fine but I haven't put it back in

yet and am thinking how to insulate my ota. I think a layer of felt wrapped

around the bottom end may help. Any ideas anyone?

NGC 3190 is the mag. 12.1 SA(S)a pec. spiral in the centre and shows a nice dust

lane. NGC 3187 is the bluish mag. 13.9 SB(s)c pec spiral and ngc 3193 is the

mag. 11.8 Elliptical. The galaxy at the bottom is ngc 3185 and there are a

number of other very faint smudges lurking which I am unable to identify.

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.
