coma corrector for Skywatcher 150/750 pds

[Edward Dewolf]

Hi,

I ahve been taking my first basic images for a whlie now and I am looking to upgrade.

A new camera is underway, but I also was looking for a coma corrector for my Skywatcher 150/750PDS reflector.

Can anyone advise once?

Thx

Edward

Hi

Depending upon the camera, you may not need one.

This one is very good. This one is ok. Either of the former are IMHO better than this one. All will cover up to APS-c.

There are a few others, but I've not had experience of them. These are my -hands on- opinions only. YMMV of course.

Cheers and HTH

I have the skywatcher cc and it is excellent. I have used it in both a 150p and 200pds and it has never caused any trouble:

 

The only thing to watch out for is the 0.9x reduction which can make the focuser protrude further into the light path (depending on back focus).

Thank you !

If you want something more premium and without the lateral chromatic aberation of a two element corrector then the Explore Scientific coma corrector is a great option.
