Finding M5.


Recommended Posts

Been looking for this over past weeks.

Think I may have found it tonight .

With my ed120 it's just showing as a faint fuzzy ball. Using 26mm nagler.

I did try a 10mm ethos but still no real detail to be seen.

I'm sure it is M5.

Can anyone tell me if I should get good detailed views with an ed120 ?

Globular clusters respond well to aperture and magnification.  Your ED 120 will give lovely pinpoint stars, but something like an 8/10/12” reflector will go deeper and show a blizzard of stars, not just a fuzzball.

I’m not a fan of high magnification for the sake of it, but globulars often can look spectacular at 200x and above, especially with a larger scope and with good conditions, transparent sky and the object at as high an elevation as possible.

I agree with Ed, dark skies, atmosphere, seeing, object position all have a bearing. I  have an equinox 120 and I’d say all globs show up as a fuzzy patch with some stars visible at the edge of some of the larger ones. Now, In my 12 inch dob, they are a different beast altogether, much more detail visible. I suspect what you are seeing is about right for your scope.

Well atleast I now know I have found M5.

 

Hi again Paul.  You sound a bit downhearted, but your ED 120 will give lovely pinpoint stars compared with most reflecting telescopes.  Although more aperture gives greater resolution in theory, I love how much smaller refractors show double and multiple stars and open clusters.  

Most reflectors show blobby stars in comparison, unless it’s a specialised long focal ratio / tiny central obstruction instrument like a  6” F12 or an off axis Herschillian with no secondary mirror.  These long scopes are a pain to adequately mount of course.

In smaller apertures, dark skies help to reveal more in globs. Averted vision also really helps to resolve the stars further in towards the core. Flicking your eye away from the target should help them pop!

I'm not at all downhearted. 

I love my ed120.😁

And fully understand you need different scopes for certain tasks.

For instance even though Jupiter is very low my ed120 still gave me some very nice details of the surface this week.

Also spent many nights observing the bee hive and the stars are pinsharp.😁

Oddly enough, when I had my 200p I was kind of underwhelmed by M13. Never could resolve stars. Perhaps it was a collimation issue, scope not cool enough, LP, I don't know. But I had my 102mm f7 frac out the other night and at high mag (8mm and 5mm BST) I could resolve stars with averted vision. Had to keep my eye at the eyepiece for a while though.
