      #2558991 - 08/04/08 08:18 AM

i cant seem to find M4. no matter what scope i look for it in, i just cant find it. i always start with binoculars, and look a little to the right of antares. then, i do the same with my scope! and it seems to not be there!

In my 12x80 finder, Antares and M4 are both in the field of view. I would expect this to be the case with a 60mm refractor, but not sure.

It's a little tough, I even had trouble in my 10"! In the scope, go to lowest power, and go a little right, slowly. I's big and resolves in a 10", but I'm not sure about 4.5", I never found it in that. Are you looking into a light dome, or are your skies bright?

M4 is a bit of a tricky Messier object, it's surface brightness is not, umm, bright. It is also spread out quite a bit as opposed to other globulars hence the low surface brightness. In my 8" it's not easy to detect but after awhile it just appears. Sounds like you are in the correct area so here's what you do, get the scope pointed in that area, get a towel or hood, put it over your head and use your adverted vision. The glob will appear as a faint glow if you keep at it. This, IMHO, is one of the tougher Messier objects to see. Keep at it, you'll eventually find it.

I think that the best way to find M4 is to form an isosceles triangle with Antares, Sigma Scorpii, and M4, with M4 being at the fattest vertex. From a dark sky site, M4 is actually visible to the unaided eye as a small faint fuzzy spot, and is fairly easy in a properly aligned finderscope. It also begins to show many of its component stars in a 4 inch, and has a nice "bar' of stars extending across its middle. Under light pollution, it may be a little tough, but once you get away from the skyglow, it is one of the easier Messier globulars. Clear skies to you.

Light pollution in my backyard is very bad! I can spot M4....only few bright stars on my 10"! M13 is much better! M22 still not great but better than M4!
M4 is easy to find on 10 X 50 binocular in pretty dark sky as fuzzy star! When you are in dark sky and you will find M4 then marked on your paper to know the excatly location and you able to find it in light pollution when the night is right.....clear and no moon!

In my old 4.5", I thought it was easy as anything, but I saw a star where it should have been also. Wait till a good, clear and cool moisture free night to be looking at the lower constellations. There are 2 pretty clusters arount the Scorpion's tail though, and Saggitarius has a lot to offer for your size telescope.
