Grus Spiral Trio 2: 7162A and friends

Three very different galaxies in Grus. NGC 7162A toward top left is a distorted face-on spiral undergoing a burst of star formation and is noticeably blue. NGC 7166 is a large (and presumably more distant) elliptical, red, featureless. NGC 7162 to the right is a more typical half-face-on spiral.

Full field here

Field 38 min arc, north up.

Each galaxy is around magnitude 12 to 12.5. There are very few images of them out there to compare to.

There are squillions of other tiny galaxies - many spirals, a couple faint magellanic beasties, scattered about.

FLI PL16803 on 20 inch PlaneWave. Lum: 7 hrs. RGB: 3h30 per channel.

As usual, all robotics, motor control electronics and firmware, and all control, acquisition and processing software written/built in house by us.


We've been out of the game for about 6 months due to the death of our third generator, the decision to go solar, and the usual effects of Covid on imports. We went with 4.8 KWH worth of batteries/inverter from Mobile Power Solutions in Qld. Superb.

Thanks muchly Allan. We can see the banding if we lean on the brightness slider. Almost certainly due to too-heavy-handed wavelet noise reduction causing posterization in the blacks. One day I'll have a think about how to stop that happening. In the interim, nobody to lean hard on the brightness slider!

An enchanting field replete with galaxies galore. Much fun is to be had in wandering around the field in the image.

Thanks Rodney. Kinda like they are all "background" galaxies. No great big M83 in the middle.

Yep, we've been missing this. You're right about looking and wondering. What is out there? Glad they're a long way away.

Stunning field! I've spent a long time looking at that image.

So.Many.Galaxies!! Wow

Can I ask what causes the banding across the image? Looks like fingerprint lines
