Fornax Galaxy Cluster

Always wanted to image one of these. 65M light years away to the center and quite a lot of faint fuzzies n the fov.

Large here Fornax Galaxy Cluster

Inverted Fornax Galaxy Cluster

FSQ106n
STL6303e
APMach1

7.5 hrs of data

Thanks for looking

Not the most common type of target for this type of scope huh?... but that looks pretty good David ...aaand the reason it is on my excitedly looong list of potential targets for my new FSQ ...figured I'd fit in just about all member galaxies with my chip..? I like the inverted version, that's how I spotted NGC 253-dw2

Mike: Oh, wow!

Many of the ellipticals are not completely featureless, but show evidence of their heritage.

Trish: Half the NGC catalogue in the one picture.

That’s brilliant David! Amazing what can be done with 4” aperture. I love the processing how the galaxies just appear to pop against the nice dark background.

Well done David,
how is that possible from the bright lights of Sydney?
Are you using a light pollution filter?

cheers

Not too difficult.

It sits pretty high up...I imaged the same cluster about 4 years ago, but not with a venerable FSQ and ultra wide field as in David's post.

No LP filter. The trick is to get access to a very dark site which am fortunate to have however you can see what Peter is pulling through from the burbs so it’s possible just need a shed load of data and very good gradient removal skills.

Thanks Colin. Wanted to keep the background as dark as
Possible and it’s probably slightly clipped so there’s some very tiny fuzzies that didn’t make the cut.

Tempted to keep on going with LUM to get more detail but the features you do see are pretty cool.

Would have loved a bigger chip. As you say, odd choice for wide field but just the scale of just how many galaxies are grouped together in the FOV was enough of a kicker to give it a go.

Thanks all for the comments.

You've inspired me to add it to my list.

I'm finishing off data capture on the Grus Quartet at the moment (grr, cloud/rain/Moon).

Really well done David. I like the contrast between 1365 and the rest. I presume it's just in the foreground and not physically part of the cluster.

Cheers Geoff. Looking around NGC1365 is listed as part of the cluster listed between 56 and 60m light years away. Core of the cluster is apparently between 60 and 65m light years depending on which site you are looking at

So yes, an interesting contrast.

Cheers

OK - I thought it was from Sydney & the bright lights.
