Description

NGC 5302 is a magnitude 12.2 Lenticular Galaxy in the Centaurus constellation. Size is 0°01'51.00" x +0°01'15.48".

While not the dominant galaxy in this field, it is close enough to center to acrue naming rights. IC 4329 will just have to live with it.

There a lot of interesting galxies across the field. NGC 5291 shows an extensive disrupted detritus fields with a lot of active blue star forming regions well away from the core, probably from its interaction with a smaller companion.

It looks like we might be be getting some cold dry nights at last and with the last quarter moon rising late, this was a great time to test my newly serviced MYT mount.
I used a professional Paramount supplier and after nine years it needed some TLC. I have stripped and lubricated a Losmandy GM8 no issues but this was a much more sophisticated piece of machinery and it wasn't worth risking it trying to follow the Video guides as I have seen forum posts where it did not go well.
The difference was obvious; much, much better guding with some recurrent tics in RA gone. I really don't get enough clear sky to blow time on problematic PEC traning and as long as the object centers and PHD which now has a PEC algorithm built in, can give me a neat cluster of stars under .5 arcscond deviation (*subject to seeing) , I am good with that.
The results confirm that a proper service was overdue and worth every penny. I used Peter Ward at ATScope who did a great job for a reasonable $300 AUD plus shipping so it cost me just under $600 all up.

Seeing was fair to  pretty good for the last two nights so no complaints, especailly as I did not get one satlellite trail oin the first night. Not one. Elon must be sleeping on the job.
He made up for it the next night as I got an earlier start having spent an hours or so the previous night realigning the mount and Starlink satellites dominate the early evening sky.
The fainter stuff get fixed during integration by setting ESD Signifigance to .05  (Winsorised Sigma clipping Sigma High of 2.2 does the same job) . If I have time the bright trails get the Clone Stamp treatment. It would be nice if RC Astro could come up with an AI powered SatelliteXTerminator to handle the bright stuff as it is only going to get worse. Last month in on single 3 minute exposure I got 8 very bright trails so that one went in the reject pile.

With Centaurus and Hydra well placed, there are a LOT of galaxy fields still to explore in the OZ winter night sky.
