I definitely agree!

Good luck! Don't be afraid to try quality orthos, they are magic in a good binoviewer and I HIGHLY recommend them. The ergonomics and ease of use are bloody fantastic. The FOV seems much wider than in mono mode.




Any specific ones you would recommend?

I would recommend the ZAO-IIs of course. But more realistically , I have had excellent results with Brandons, UO Orthos aka KK Circle T Orthos, and TV Plossls. There have been numerous threads on the subject just search for "planetary" in Binoviewers or Eyepieces forums. Agena Astro is supposed to have the Kasai HC Orthos in soon which are the same as the old UO HD's aka Baader Genuine Ortho's.

Why sell AP now along with the Mark V setup, the Baader T2 MaxBright diagonal mirror #1A in place of the earlier Zeiss Jena diagonal prisma #1B (was offered prior to December 2011)? Marketing or something else?

This question has been discussed many times on many forums! There is no definitive answer, I have two possible reasons that I will offer up:
1. As Roland's eyes get older (like mine) he , like me, might now prefer the slightly brighter view of the mirror.
2. Mrs Astro-Physics might have noted that they had an excess stock of mirrors and suggested that before buying any more prisms ( if they are like many companies, they would order once a year and place a big order to get a better volume price), they bundle the mirrors with the binos to reduce stock.
Either answer is as good as the other. You decide, or make up your own reason.

Do you really think transmission losses in the prism amount to a detectable brightness difference with a mirror?

I have both diagonals (and an AP Maxbright which seems the same as the Baader mirror) and to me the view in the mirror is brighter, image details pop out more but there is more light scatter around bright objects. The prism makes objects like planets seem to float in a blacker background without any scatter but edge details seem a little darker also. When I was younger, I did not notice much difference but now in my sixties, the difference does stand out.

I have both T2 prism and maxbright T2 diagonal with my Mkv
The mirror stays in the box!!!

As others find: Prism eliminates scatter and gives a very dark blacks.
The 1.8 2", in my opinion is as good as it gets compared to all the other 2" barlow/maginfiers.....apart from by Baader FFC
YMMV

Rex, indeed possible at a certain age we are better off with a dielectric mirror diagonal!
