Re: Is the William Optics RedCat 51 worth buying?

I have had 2 Nikon 180 F2.8 ED lenses and a Redcat 51.

The Nikon 180 was a good lens a long time ago but by today's standards I think it lacks a fair bit. It has chromatic aberration wide open. Its not as sharp as a Redcat.

The Redcat 51's main issue is tilt. It comes with a tilt adjuster now and be prepared to have to use it as my copy was quite off in tilt so corners were quite bad on a full frame.

If you correct the tilt its a good performer.

It is sharp though. F5 is fine for widefield deep sky.

I think though that you would get better bang for your buck by getting a similar costing telescope from William Optics. They have a few around 60-81mm in aperture. The Redcat 51 objective is about 50mm in aperture.
