- ACF f10
- field of view
Nice field of view for what it is!! Works better without the focal reducer on my 12" ACF f10 and have other scopes to try it out on and as usual when you get something new the weather is not cooperating lately.... clear skies!!
This eyepiece allows you to have a large exit pupil on a slow tubes, like 1:10 and slower, so it is a musthave for serious deepsky observations. It fully covers all available TFOV in a 2" focuser. Best views of M81&82 galaxies I had so far. The eyepiece is very light for its size, and despite a simple single-layer coating it provides crisp and bright image. The eyelpiece has a very clever feature: its top part can be unscrewed for the cleaning of top lens. The only drawback is the lack of dustcaps.
I thought that the glass would be wider but I am new at this. Most of Pleiades fits in the view - love it.
This is the largest eyepiece in my collection, and in every scope it looks great. I can really move my head around and get a wide field view of some larger object. Can be used while wearing glasses too.
just as i expected a little finer detail compared to my 40 mm pentax. Been able to use it only a few times so far. Pretty sure im gonna be happy with it
I recently bought a C11 for deep sky and planetary imaging. The challenge of playing with a long focal length scope is that your other eyepieces' FOV is too narrow, even with a 40mm... This eyepiece with its crazy 56mm makes looking through C11 at Saturn a wow experience!!!
