Very tidy result
Thanks Peter. I mainly upped the black point as I had it brighter before and looking at it again it was distracting.

Yes it a very interesting field of unusual galaxies.

So much detail in both.

Thanks.

Ross.
Cheers Ross. It was a few nights of excellent seeing and the setup was working beautifully. One of those nights when everything came together.

I had several of them a few weeks ago. The seeing at my home observatory was divine. I have several images I haven't processed yet from that period.

[QUOTE=madbadgalaxyman;846600]Very nice work, Greg.

This part of the Virgo Cluster is my favourite northern field, as so much is going on in this part of the universe.

Your image shows, very well, the gigantic difference between M84 and M86, both of which are usually thought of as being "elliptical-like galaxies".

M84 is a classified, at face value, as a classical elliptical, having regard to the observed shape of its two-dimensional outline and also because of its observed very-rapid falloff of surface brightness with increasing galactocentric radius.


Thanks for that. So I should do some more exposure on this to pick up that faint halo structure. Thanks very much for pointing that out as I often look for galaxy targets where I can pick that sort of thing up.

Greg.
