This little galaxy in Lupus is not often imaged. It lies about 40 Mly to 60Mly away - depending on who you consult....
It is a Seyfert galaxy type Sac, with an active galactic nucleus.

It is about 45kly across, and is listed as MagV 13.6, and MagB 11.6, with a surface brightness of 23Mag/sq arcsec.

This image was shot from Mt Macedon over 2 nights in seeing conditions which varied from poor (2.8") to atrocious (8" !!!!!). I managed to keep a total of 5hours LRGB with a cut-off 4.8".
Rather than throw the whole lot out, I took to the data with a little help from BXT.......
FOV is 13' x 16'; Officina RiDK 300; Moravian C1X 61000 at analog gain 3.

Well Mark, if the seeing isn't playing ball, there is little we can do about it but you certainly managed to salvage something out'a that soup, for sure, nice work Reminds me of NGC 6300 in Ara, they could be twins.

Thanks guys.
Mike, thanks for your comments - much appreciated. (Recent tree work at the Macedon farm has opened up a lot more sky, and the possibility of of longer longer observing time - I hope the weather will let happen....)

Did or do you know Bert Candusio?

I don't know him - but do know he lives quite close to us - we are just outside Woodend.

He had a telescope hosting facility, the Macedon Ranges Observatory, about 18km NNE of Woodend about 10 or 15 years ago now but I believe it has closed down now and was repurchased?

The hosting service is dead - there are a few fossil remains on the internet, but they lead nowhere....
He is now involved with the Central Victorian Insect Collection, recently moved from Bendigo to Woodend. Maybe he got sick of the clouds
