Personally I would not say the refractor is to heavy for the mount unless you are planning on a AP session.

For visual observing it is more than enough. 

If it helps my 150mm f/8 weights 12,7 kg and the Celestron EQ-5 is rated between 11,4 - 13,6kg

It works just fine for visual. 

Do I just need to make sure everything is balanced I mean I have a 10mm Delos eyepiece and 24mm explore scientific they're quite big not really heavy tho.

Hi, I have the 127l bresser messier on a eq5 mount although I had no issues with it, I manage to balance it it balanced well, although I hear that this scope is to heavy for this mount does anyone agree with this or does anyone else have this scope on a eq5 with no issues?

Hi, I'm thinking of buying the explore scientific coma corrector although I heard it requires 35mm in travel, I have the 8" Skywatcher dobsonian although I heard the skywatcher Dobsonians usually do have plenty of intravel for this coma corrector don't know how true this is.

Hi,

I got a eq5 goto mount I had it a while anyway I just can't get the adjust of it I live in the northern hemisphere I had the mount and everything set north I put in correct details on the remote I had the mount and scope balanced it was a skywatcher 120mm startravel I had mounted anyway I done a 2 star alignment anyway I choosed a star that was high up like Deneb anyway i wanted it to slew to Deneb and it slewed no way near Deneb it slewed the opposite direction is this just a error that naturally happens with the kit? Even tho I was polar aligned and had all details in correctly and mount was balanced.

I'm thinking of replacing my 12mm bst with the baader Morpheus 12mm is the Morpheus worth the upgrade?

I'm thinking of buying the explore scientific coma corrector as the televue paracorr is out of my price range I heard it requires more intravel is there any trick to achieve in travel with it?

I've got a F5 and f6 scope I'm looking into the baader Morpheus eyepieces are these better then the Hyperions in fast scopes?

Has anyone had any experience with the Baader Morpheus eyepieces in fast scopes what are they like in terms of edge sharpness?

Is this another Celestron Xcell eyepiece giving you problems or the same one you posted about below:

If so, why the duplicate post?  Why not continue the original thread with your current question?

It's the one with bits of orange around it would the 18mm Delite be a good upgrade from this eyepiece?

I got a Celestron xcel eyepiece and it seems to be showing astigmatism in my scopes I know it's only at the edges but I find it distracting me scopes are f5 and I got a f6 dob anyway would the 18.2mm Delite be worth buying replacing my 18mm Celestron xcel?

Hi I have a Celestron xcel 18mm Eyepiece anyway when I use this eyepiece in me skywatcher startravel 120 f5 the stars at the edge look very seagully astigmatic although I heard these Eyepieces are meant to be good at f5 could these "seagully" shaped stars be coming from the scope or is it just the eyepiece not being a good match for the scope?

Hi I have a dielectric diagonal when I use it I get vignetting is dielectric diagonals prone to have vignetting if so what dielectric is recommended if the vignetting is coming from the diagonal?

Have you tried adding a field flattener to the front of you diagonal?  I use a TSFLAT2 with 15mm of spacing in front of my 2" diagonal in my short refractors to do a good job of flattening the curved field.

You can tell if field curvature is the issue by focusing a star in the center, and then moving it to the edge, and seeing if it focuses to a tighter pinpoint by refocusing.  Most inexpensive short tube refractors have field curvature.  The Tele Vue NP101 does not thanks to its Petzval design, though.

Could I also be seeing pinched optics?

Do stars in the centre of the view look like this or is it just those towards the edges ?

They do look like this a tiny bit in the centre but worse to the edges.

Do you have astigmatism in your eye(s)?

Regards Andrew 

Yes I got glasses it doesn't do nothing so I think it's in the scope.

Hi I got a skywatcher startravel 120  f5 anyway when I do a star test when I defocus stars they look rugby ball shaped this happens in all me eyepieces even my televue eyepieces anyone know what could be causing these rugby ball shaped stars? thanks

Sounds like astigmatism. May well be the eyepiece rather than the scope. What eyepiece were you using ?

 

 

Could it also be a combination with the diagonal aswell could I also be using a poor diagonal?

On me skywatcher startravel 120mm defocused stars at the edges are appearing slight rugby ball shaped when I focus them they appear to be seagull shaped anyone know what this is ?

Hi i use the stock skywatcher finder scope for some reason it won't focus I'm unlocking the ring at front and turning the front lens for some reason the stars won't focus me finder seems to show really bad abberations the stars won't focus into pin point they look like seagulls shapes in me finder anyone know why and what can fix this ?
