Now, I want add Supercharge Service of Denkmeier Binotron 27.
So what you get is:
*****Clear Aperture on left eyepeice side 25.1mm before Supercharge, and 26,69mm after Supercharge
*****Clear Aperture on right eyepeice side 25.1mm before Supercharge, and 26,69mm after Supercharge
*****Clear Aperture on back side when 2" adapter is attached 26.1mm before Supercharge, and 26,69mm after Supercharge
Pictures with needed details are attached...

From 26.1 to 26.69mm
What is the price again?

Thats on scope side.
On each eyepeice side you have originally 25.1mm, and after Supercharge it is 26.69mm.

I think what alarmclock missed is that:
From 26.10 to 26.69 from the scope side and from 25.10 to 26.90 => both sides = 26.90mm clear aperture.
The key improvement with specifications like that is that you can use for example Panoptic 24mm eyepieces with minimal vignetting.
EDIT: Denis, feel free to correct me if I misunderstood.

As I said before and as you might know, binoviewers, as any optical and mechanical device design, and especially with high-end products, are not designed from some random numbers thrown on a drawing board. Every component is carefully thought and weighted to meet all kind of technical and cost-wise specifications.
If a prism is set to be X in width, there is a reason. Is a baffle diameter is set to be X, there is a reason. There is always a reason. That's why quality companies hire engineers. If this ring you cut had those dimensions, it's not just "for the sake of it". It has been designed. You just can't cut everything haphazardly so that it LOOKS better. It might, but it won't perform better, all in all. Stray light control is just an example.
"Supercharching" a binoviewer in your workshop is claiming that you can improve what a full team of experts in a design office worked on assiduously for months. It's interfering blindly in a finely balanced equation. As you may know, an optical device design is a sum of compromises : if you cut somewhere, it will recoup elsewhere.
That being said, if an amateur astronomer wishes to spend 200$ to try upgrading his already optimized gear, good for him, good for you. But in my opinion, this is pure nitpicking, and I would not gamble on my expensive equipment for a few more % light gathering.
That is why I have been following this topic. Now that I expressed myself, I'll leave, I obviously won't be welcome here anymore

Well, a question has been asked and I am curious as to the answer.
I don't doubt that the binoviewers can be supercharged i.e. the free diameter extended. Is there a cost somewhere performance-wise? Any unwanted reflections? Any other factors that need to be taken into account?
The only reason I can think of why most of these binoviewers come with a specific diameter at the scope and eyepiece end is simply a matter of cost, i.e. to provide binoviewers to the specifications that Denis offers means passing on the cost to consumers, $200 or whatever it is and the market is not available at that price point to justify the investment.
Edit: Well $90 for another couple of days but standard price $199...

Why on earth would engineers reduce the clear aperture of their binos prisms ON PURPOSE, with rings too small in diameter? Commercially that doesn't make any sense. If the company specified a smaller clear aperture to reduce costs, they'd have put smaller prisms.

Just a reminder folks that the Vendors Forum is specifically for:
"...the use of Vendors to post announcements of up coming products, special sales and promotions, and any other information the vendor may feel is of use to the members of CN concerning their products or business. It is also for the use of members to post questions concerning said posts. The Vendor forum is not, for the use of members to post complaints or request for guidance for settling issues with vendors."
My question above is raised as I want to understand if there is a performance loss in any way from the supercharging service. Denis indicated in previous posts that there isn't but I would like to understand why, which relates to product performance.
Please stay on topic and respect the raison d'être of the Vendors Forum and refrain from comments re scams.

Thank you all for comments! Noo needed to worry about anything negative commented.
I do many many experiments with most of world known serial, and non serial produced binoviewers many years, and Supercharging binoviewers is really great improvement, for some models it is more usefull, on some less, but improvement is there, especially if you have epcs like Pans 24mm, which are very popular epcs for binoviewing, and you posses binos with lets say CA 20mm, which can be Supercharged lets say to 25mm.
This means you xcan use Pans 24 with minimal vignetting vs original setup.
When we talk about Supercharge, it works more or less (depending on modles) like tuning cars or other stuffs, lets say, some could ask, why some Mercedes originaly produced, should be tuned from side of AMG, Brabus, Lorinser, or some even egzotic home made costum work........
I descovered Supercharge few years ago, and I wouldnt do it if it does not have positive results for observations!
I actually enlarge apertures, blackening some parts which was not blackened from side of bino producer, and I use some other usefull solutions to holds prisms in some models, which bino producers not offer, and I can say one very simple example: WO, TS and simmilar bino prisms holds VERY TINY screws, which can cause prism hurts like cracks of prisms, which is last you wants that happened, but it can happened becasue many reasons, like for example when bino dropped hardly, or you clean bino interior taking prisms out of binobody, and when you turn them back, if you tighten prisms too hard, prisms can be cracked! ....there are also some more little usefull stuffs, depending of bino models.....
But, after Supercharge, you absolutely do not get any aunwanted stuffs, like some additional internal reflections or simillar, which many affraids but on the contrary, after service you increase Clear Aperture of your bino, which will allow you to use epcs with bigger FOV and longer focal lenghts, and on scope side, you will get a bit more already precious light from your scope in your brain! Also, after blackening some parts, you even minimize some unwanted internal reflections.
All in all, this job require LOT of experience, plenty of meticulousness, patience and precision!
I do this with BIG love, which I do in start for myself, for my satisfaction, as a critic, and guy who love to have as max as could be utilized astro stuffs, becasue I really enjoy very much in astronomy, especially when binoviewing on any scope!

My dear CN members, after long thinking, I make decision:
to be more approachable and affordable, I will offer Supercharge service to ALL, for 100 USD, which price will be firm in future!
Thats not my primary job but I do it with BIG love, so any interested can contact me without any hasistation.

Denis,
Thank you for the clarification. Bringing in the analogy of cars makes it easy to see the value in this.

Addition on Supercharge service:
Arcturus, AST Optics and simillar binoviewers:
What you get is:
---25mm Clear Aperture on left eyepiece side (Supercharged)- instead 20mm in original setup
---22mm Clear Aperture on right eyepiece side (Supercharged) - instead 20mm in original setup
---26mm Clear Aperture on telescope side (Supercharged) - instead 23mm in original setup (huge improvement)!
These binoviewers have real self centring eyepeice holders, do not have polarisation effect (big advantage), and are very affordable!

Here, I add picture of Baader Mark V binoviewer right side that you can compare before and after Supercharge!
As you can see, in original setup, interior and glass are not blackened, while after Supercharge you get blackened interior and glass. This will get you more contrast images, and less internal reflections!
Also, after Supercharge you get 2mm increased Clear Apeture (26mm originally, and 28mm after Supercharge).
This will allow you (when we talk about Mark V and Zeiss like binos) to use Panoptics 24mm (with field stop 27mm), Explore Scientific 24mm 68deg FOV (with field stop 28mm) or simillar eyepieces who have field stop 27mm or 28mm, without any vignetting, and without any blurredd edged in field of view!

Hi Mike,
I do not have momentaly pictures of Supercharged TeleVue BinoVue.
BinoVue have originally prism, beamsplitter, and correction glass, 28mm diameter (larger than Binotron 27, which have 26.69mm CA), and it have in original setup already max 28mm CA on scope side (where CA on 1.25" BinoVue scope adapter is 28.5mm, which is actually larger than max possible CA of beamsplitter)!
Origianlly, on left and right eyepeice sides, it have 27mm CA (deep inside where is correction glass), and 27mm CA (inside binobody).
Both left and right eyepeice sides can be Supercharged to full 28mm CA, which is 1mm increase, which allow using Explore Scientific 24mm 68 deg and simillar eyepeices without vignetting, while they have field stop 28mm!

Ok Thanks Denis. I knew about the CA of the prisms but wasn't sure if the blackening (as seen in the Mark V) was something that the TV Binovue needed as well.
I little to no Vignetting using the 24mm Pans.

Wanted to chime in here with my recent supercharge servicing Denis provides.
Submitted a new binoviewer to Denis for supercharging, hard deal to pass up. He described exactly what he could do for my particular set and did just that, and very professionally! Great service all throughout, kept me updated frequently and shipping was faster than I expected. I highly recommend Denis in case you are sitting on the fence about upgrading your binoviewers. Very happy I did it, thanks Denis!

I just purchased a Supercharged WO bino from Denis and I have been very pleased with my purchase. Excellent work, great communication and fast shipping. The increase in aperture with the WO bino's is very noticeable which does relate to a brighter view. If you are thinking about having him supercharge your bino's do it you won't be disappointed. Thank you Denis!

I thought I'd add the email I just sent Denis as an update to this post which adds more detail.
Good Morning Denis,
Well it's morning here and it's 20 deg. F at 7:00 am. I just got in from taking a look at Jupiter through your bino's. So I can now give you some real feedback. It's been cloudy and windy here since I got them so I haven't had a real chance to try them. All I can say is FANTASTIC!!!!! I took out my vintage modified (to accept 1.25 ep's) 80mm f15 Meade 300 refractor. I have a pair of Japanese made Meade series 4000 UWA 6.7mm ep's that I was hoping would work and I was shocked to find they worked perfectly. Collimation was dead on and at 180X I was looking at 4 bands, good color and the moon's were tack sharp. In fact I was seeing more detail with that setup than what I saw with my 7mm XW Pentax alone. Now I can't wait to see what the moon has to offer. So thank you for the very fine binoviewer. Keep up the good work my friend.
CS
Gary

A word of thanks to Denis for the superb supercharge service of my Bader Maxbright Binoviewer.
I had dropped them, my clumsy handling and they were completly useless, Denis brought them back to a better than new state.
Colimation is perfect, merge is immediate and this service at this price is highly recommended.
I'll try not to drop them again.
Best Regards
Carl
