Gso coma corrector query

Has any member had any experience with the new GSO coma corrector and how does it compare to the one from Televue?

There were some reports and comments about it several weeks ago, on Cloudynights, but I can't locate them.

Your help will be appreciated

Would be interested in a link George?

Have you considered a Baader MPCC - they have lots of runs on the board for many people.

What sort of scope and/or camera configuration would you be using?

Thanks for the reply Rob. I am only a visual observer. I already have a Televue Paracorr which I like a lot. Some nights I use two Newtonians, a 12" F5 as the main scope and a 6" F5 as a rich field. I do not like to move the Paracorr from one scope to the other, so I was thinking of getting another Paracorr but the cost is over the $400.00 mark. On the other hand the GSO unit is less than half the cost of the Paracorr. This is the reason for my post.

Thanks again and clear nights

The GSO version is like the earlier TV paracorr in that it has no tunable top. Although the designer of the GSO apparently posted on CN that you didn't need to optimise the distance between the EP focal plane and the corrector - most on there were looking at solutions to do just that, using parfocalising rings etc.
I considered getting one because of the price (and I see they are available at Andrews now) but in the end went for a current model paracorr from astromart instead (price difference was small).

Thanks for that JethroB76. I seem to remember something along the same lines. I believe a CN member called Skycaptain fabricated a little device to get an affect similar to Turnable top from TV.

I cannot locate that post on CN. Do you happen to remember when it was posted?

Thanks and regards

Hi there,Just wondering how all this went, as I am also interested in the GSO coma corrector for visual only.
I have a 10" gso dob with nagler and pan eps.The 24pan does show up coma near the edge of field(radiating comets)which would be nice to tidy up.I have not noticed this with other eps.
I have had had an eye test recently which shows 1/4 diopter.I use a catseye coll system which I think I am using correctly.
I phoned the helpfull guys at Bintel --and this coma corrector was suggested.
If anyone has any thoughts or experiances to share about this model---it would be appreciated!
Cheers-Eric
