Questions and Answers

Grenier (2022.09.19)

Hello, I was unable to post a review on your Levenhuk Product ID coma corrector : 50755. I am completely satisfied with its use on my 200x800 telescope with my Morpheus eyepieces, especially with the 17.5mm and 12.5mm; beyond that the corrector is no longer necessary. I would like to know if this corrector has 2 or 4 lenses, and if they are FMC coated? Sincerely, Jean Grenier.

Customer service:

Hello Grenier,

thanks for your request.

It is four element version of coma corrector.
I will ask our tech support if it is FMC coated. I will get back with an answer shortly.

Could you please tell us why exactly you could not publish a review on our website?

Have you received some kind of error message?

Is it suitable for f/5 Newtonian?

Customer service:

Yes, it's suitable in theory, but Levenhuk Ra Coma Corrector is recommended for use with f/4 Newtonian telescopes.

Tammie Allen (2013.06.05)

This corrector is only for f/4? Does it work on f/6?

Customer service:

Levenhuk Ra Coma Corrector for Newtonian telescopes suits the f/4 more. It's less effective for f/6.
