Spsp speaker on galaxies

[mozzie]

Hi all
having a look around our moon light infected skies with steve the next door neigbour and we were talking about spsp and one of the nsw members gave a talk on merging galaxies we were wondering what they called them so we can have a look next new moon

Peter,

I didn't see that particular talk at SPSP but the Arp catalog is a good start.
The Arp Peculiar Galaxies (http://338arps.com/) catalog not specifically being merging or interacting, many of them are and worthy of a look.

thanks john while at spsp on the sat night some of the nsw members done some presintations. this member was showing pictures and he also done some drawings while observing im shore there was 200 or 400 clusters of galaxies it was very interesting im trying to find that catalogue name and observe them

Peter,

They are the "Hickson Compact Galaxy Groups". I think there are around 100 of these groups that average about 566 members. They are also very faint, 15-16th magnitude.

Sorry typo, they average around 5-6 galaxies each group, not 566!

Hi Peter, Glenn & All,

I wasn't there but from your description, I'd put a lot of money on the speaker being Scott Mellish -- an ASNSW mainstay, master deep sky observer, talented eyepiece sketch artist and all-round good egg. One of Scott's passions is the Hickson galaxy goups which are all very compact, mainly quite faint galaxy groups.

There are 100 exactly in the list and they are somewhat weighted to the northern hemisphere. Many are either lowish in the north or over the horizon for us. If you are an experienced observer with a dark sky and +12" 'scope (better +16"), they are some of the best fun you can have with your daks on.

I've seen about twenty-odd of the groups, and my favourites are Hickson 48 (Hya) and 44 (Leo).

Here is a full listing:

Hi Les and all, the Hickson galaxy groups are a good challenge for deep sky observing, I have seen about ten, with furthest north group being Hickon 92
Stephens Quintet:)
I love trying to squeeze the last photon of light out of the 16";)
They are great when the seeing is the best.:D

thanks guys yes that was what i was after the hickson group

one more question dr fred watson was the guest speecker and at the end of his fantastic talk there was a 3 minute movie and we flew through the universe looking at galaxies thet have been found and plotted hr was saying that the movie could be down loaded of his sight there was many people there absoultly amazed does anybody have it and if so it should be posted here on iis for others to see absoulty amazing:jawdrop::jawdrop:
thanks for all your help mozzie

I'm assuming that was either 2dFGRS or the new 6dF data. You can find the 2dFGRS movies here: http://www.mso.anu.edu.au/2dFGRS/

I'm fairly certain I've seen some 6dF animations, but with a quick search I couldn't find it on the website: http://www.aao.gov.au/local/www/6df/index.html
