I received a email from Bresser (Germany) this morning and thought I would pass on some information.

They are releasing a 90mm f/13 and a 102mm f/13.2 and the new scopes will be going through final QC on 10 April 17 then will be in the European shops soon afterwards.

I do not know if they will be available on the USA market though.

I am not sure what the price of the 90mm is but the price I was quoted so far for the 102mm is 259€

Thanks for the link spongebob, I was part of that conversation while it was going on.

I was just letting people know that there is an actual date the scopes will be showing up now. smile.gif

Sorry Gabby, didn't see your 'eye'.

I emailed ES and they said they didn't have any plans to bring them to the US market.  Oh well.

They will probably have to be ordered either from the Bresser website or APM or even TS. We simply can't find the models from the Bresser Messier AR series with the new focuser in the U.S. Imagine these f/13 ones.

What brand is your 150mm f/5 Newtonian reflector?

Thanks for the update.  I would love to get my hands on one of the 90mms.

I imagine the 4" f/13.5 would be an amazing solar scope for the price.

Hi.

 

I suppose that they will all come with the new 2.5" Hexafoc focuser. Right?

Thank Gabby.  That's awesome.  Many EU dealers ship gray market Bresser models here.  I have a wish list.  I want 6" f/8 and 5" f/9.4 Bresser Messier achromats and if they come out with the 102mm f/13.2, I would love to have one of those as well, provided that they come in the smart white tive with white trim and red details.

 

Regards,

 

Jim

They still do.  5" and up .  But wait times have become very long.

No,in the ad they have only original single-speed focuser.With 2.5" Hexafoc focuser they would be more expensive,but I hope we can have some upgrades.

The 102/1350 prototype was shown with a single-speed Hexafoc, the 90mm had the simple 1.25" focuser. I will be quite disappointed if the 102/1350 doesn't come with the Hexafoc, since the 102/1000 does so, at a comparable price.

I recently took delivery of a Carton 100mm F13 (see Ed Ting's review). Most of the hardware was built around the optics set as the optics and the front cell are the only Carton pieces. Waiting for a focuser to arrive as it came without one. Considered putting an FT on it but decided that was not going to be money well spent. Found a used white Vixen 2-speed focuser at a better price than anything better I could buy at Orion. I have owned a 6" F15 built by Barry Griner (Jaeger optics, D&G tube, Unitron focuser).
I originally bought it as a possible full length guide scope for my Cave 12" Cass/Newt restoration project. But it might end up with a life of its own. Thinking about adding a long focus 60-80mm scope and maybe using it at star-parties instead of my 115T APO. Pretty sure my Vixen GP can carry it if I use 2 CWs as the GP carried my Borg 150ED fine that way. Need to find a fairly long Vixen type rail although I have one of the long true Vixen ones. Came with a pair of WO rings and I have a set of the WO guidescope rings I can mount on it. Now I need some pictures of the Carton logo so I can have it added on the tube.

I to am hoping that the 102mm does come with the hexafoc, I know a couple guys are going to NEAF and they are going to check the Bresser display to see if they brought these along or at least get some more information on them.

If they manage to get some pictures and info I will post it.

I have the F10 version (102/1000) and the topics are really good. A little trace of yellow tonality but a general really good quality.

I need to collimate the doublet and after it the scope as an incredible performance till 250x. on the moon and over 300x on double stars.

The problem is the mail cell made of plastic. No panic during night observation but surely not raccomended for prolungate solar vision with a herschel prism.

Probably you can use a normal mylar or astrosolar filter but in this case the performances are less incisive.

Surely I will buy the f 13 version (it's cheap) to test it.

A lot of the refractors are currently gone from Bressers main European site, I wonder what they're up to?

Hi Guys, here are my first impressions of the 90mm f/13.3:

 

https://stargazerslo...itial-thoughts/

 

In a nutshell - good lens as you would expect at f/13, but I'm not impressed with all the plastic on this scope, even with it being cheap, especially the plastic clamshell clamp on a scope this loooong! The 102/1350 version looks to be a much better proposition for not much more money, I wish I had opted for that one instead!

Hi.

 

It is being sold with the 2.5" Hexafoc focuser, also known in the US as Hexagonal. If you'd like to take a look at it, just click on the link below:
