Astrofest purchase. (it arrived early)

Baader Planetarium 90º Amici roof prism with BBHS multi coatings.

 

The prism is very solid (it needs to be) and is built to the Zeiss factory standard with T2 threads on both sides.

Although it only has 31mm of free aperture, i've brought it to use solely with my Mk 5 bino.

Optical length is a mere 47.5mm

Now i know why these things are so difficult to make well, and are the price they are.

Inside looks rather complex to say the least.

Here it is with the Baader T2 quick changer fitted (to attach the bino) and a smoothbore 2" barrel fitted (filter threaded)

and a comparison with my other normal (reversed left to right) diagonal. Its about 10mm longer in the body.

This Amici prism with give an erect, non reversed image.

I'm only going to be using it for Lunar, astro wise.

Its main use will be for terrestrial and bird / nature watching.

How it performs will be a post for the future, as i'm without refractor at present.

I've always been a fan of Baader stuff Mick.

Although it says Zeiss on the website, its not actually Zeiss as such.

Its just made to the same standards. Allegedly.

If you want the best of the best, Baader do one that costs more than double the price i paid for this one.

But as i don't use 2" glass, i didn't consider it.

 

But I kind of have my doubts whether this new Amici will be as good as your own.

How does yours perform in daylight ?? 

 

Hopefully this one will be ok.

But i may be able to detect that diffraction spike (is that what it is ?) that is reported

with the budget models. Reviews seem positive enough.

We will see.

Never used it in daylight so can't comment on that.

 

The diffraction spikes are visible but only on really bright stars such as Sirius, Capella etc. I was told by APM that even on the top of the range Baader and APM diagonals you will still be able to see diffraction spikes, To be honest it doesn't bother me as I spent years looking through dobsonians so I'm used to spikes on stars. Have never seen any defects on the moon. In fact the moon looks fantastic when using the AMICI, seems to be sharper then the supplied Skywatcher diagonal.

You won't be disappointed Rob. I got one for my telementor. Certainly haven't seen the diffraction spike yet, but only really used it on the moon. Just a shame it doesn't come with nose or eyepiece holder. Like you I opted for a click stop but only 1.25.

Thanks Andy. Its not even a click stop, just a dovetail type fitting that the bino couples to.

Just had a look at those Telementors. I'm assuming if you are using the Clickstop, yours has been adapted to use 1.25" previously ?

According to this review i read, its quite difficult to do, as the scopes were all built to take .965 eyepieces.

It looks an interesting scope, and with it being Zeiss from that era, will certainly be valuable.

Was it built in East Germany, with the fixed eyepiece (ie focusing achieved by moving the primary up / down ?

Yep that's the one. Carl Zeiss Jena Telementor 2 from about 1985. I converted it to 1.25 as I unfortunately didn't get any eyepieces with it. Just two adapters from teleskope services. I was lucky enough to pick it up as a job lot with a 105/500 rubinar mirror lense and a couple of meade skylux's. Really didn't know what it was but so glad I took the punt. Got £100 more for the rubinar on ebay than I paid for all four items. They don't go for major money, seen a few for around the 350 mark. At only 63mm it's not great on dso but planetary, luna and particularly doubles are a speciality. 

 

Obviously before I upgraded to the prism.
