    Yeah, I checked last night and they're not listed on ES website at all. Those who want them likely will have to import them from TS and other European dealers.

    As an update I received an email from Bresser this morning letting me know that the new Messier AR 102mm f/13.2 achromat will be going through final QC on 10 April 17 and will be available soon afterwards.
    Pricing so far (unofficial) is 259 Euro.
    Scopes: Antares Elite (Vixen Spec) 105mm f/15 (AIM-9), Modified SLT 102mm f/6.5 (Abe Normal), 2 Modified 150mm f/8 doublet (Frankencannon & Beefractor), Stellarvue NHNG DLX 80mm f/6.9, Vixen ED 115S f/7.7 (Raquel), Home made 150mm f/5 Newt
    Mounts: Manfrotto 055 Pro/ 128RC, Modified SLT, EQ-2, EQ-5, Tuned CG-5 w/ Argo Navis, Tuned ASGT, SXP w/ SB10 Binoculars: Vixen Ascot 10x50, Celestron Skymaster 15x70

    Eyepieces: An embarrassing amount of highly polished and coated glass mostly under 50°

    That's a pretty aggressive pricing! Thanks.

    It will be interesting to see how it comes with standard equipment since the nearest competitor is 100 € more.

    The mount issue can be solved for a surprisingly low cost. A plastic 10ft or 3 meter downpipe is cut into three equal length sections. Six sixty or seventy-five degree elbows become the feet on one end and point directly up to fit into a vertical pier of 6 inch plastic sewer pipe about four feet long. A solid slug of Bondo glues the three leg elbows to the pier. Do not glue the legs to the elbows and the whole thing can be pulled apart and transported or stored where your neighbors don't have to look at it. The legs become incredibly stable by knotting a heavy polypropylene through holes drilled through each leg and turnbuckled (standard clothesline turnbuckles) to the pier which also allows fine tuning of the pier to vertical if you are using the take apart portable version. Inside the 6 inch pipe you can slide a six to seven foot 5 inch sewer pipe which fits quite snugly. Staggered holes drilled through both pipes allow locking at various desired heights with any handy plug material. I cut two horizontal ears into each hole and used old locking plugs from a garden table set of legs. Line up the ears, slide the plugs through, and turn ninety degrees to lock them. This arrangement is height adjustable with a load by using a bottle jack under the inner pipe, which has a three quarter inch thick plywood disk cut to its diameter and secured to the end with a standard glued sewer pipe cap, which supports the load as you pop it up from one lock height increment to the next. Blast a silicone window lube or WD-40 onto the sliding surfaces and it slides smoothly and prevents the spiders from nesting. This arrangement has survived 15 Canadian winters and holds my 6 inch f15 Jaegers Bazooka very nicely. If you live near an airport, as I do, you can save yourself a sudden tire screeching visit by VERY nervous looking armed men, if you invite them for a look see BEFORE you set it up.

    Just eyeballing the photos it seems to have a 2" focuser which I prefer.

    I believe the 102mm has the 2.7" Hex focuser with 2 speed as an option. The 90mm has a single speed rack & pinion.

    Sounds interesting: I like the idea of a stable adjustable pier, so can you upload a couple of photos please? I'm not sure how the elbows attach to the 6" pier, or what you mean by "knotting a heavy polypropylene through holes drilled through each leg and turnbuckled (standard clothesline turnbuckles) to the pier"... I think I know what you mean, but I am not sure what a "standard clothesline turnbuckle" is, and I would like to see what the "old locking plugs from a garden table" look like.

    Thanks heaps.

    The version that I described is at my cottage. I though that I had a photo of it but I can't find it. Version 2 is sitting on my almost snow-free patio so here are some photos. It differs from the first one by using more of the old table locking hardware to secure the legs. I used some stiff plastic pipe instead of turnbuckles to brace this one, and the pier height locks just sit in cut outs at the top of the pier instead of using complete drilled holes.IMG_20170322_152824.jpgIMG_20170322_152938.jpgIMG_20170322_152840.jpgIMG_20170322_152848.jpgIMG_20170322_153032.jpg
