HICKSON 40 This is my first Hickson galaxy group and the observation was brought about by the article in the February 2002 edition of SKY&TELESCOPE BY David Levy,titled Meet Larry,Moe,and Curly.I had in the last couple of months aquired my 40cm telescope and this seemed an ideal target to try for as it was close to my maridian at the time of reading the article(keeping in mind we get Sky&Tel quite a bit later than our northern Hemisphere observers.
The group was easy to find as it is reasonably close to Alphard and a prominant asterism.
The group cosists of Five galaxies, the first H40a is a given mag of 12.8 and
is seen as a small oval which brightens towards the middle but this was only seen under very high mag.H40b and H40c where hard to glimps as seperate objects
and only at certain times with high mag and everted vision, the given mags of these to objects 14.0 and 14.9 respectivly.
H40d was just seen as a very small haze detached from H40a with a faint star close by.
H40eis very faint with a given magnitude was to faint and is only brobably seen in very large scopes (60cm or more).
I enjoyed the expereance of observing this group of galaxies and will be looking for more of the Hickson group of galaxies in the near future.
AS a postscript to this observation, the group was visible in my 20cm(8")SCT
A faint fuzzy patch but was not seperated under any magnification
