The pre-dispatch optical bench test is provided by Es Reid. He checks the telescope's optics are well figured and properly aligned. I.e. he checks for star-shape, colour, spherical aberrations and astigmatism. In short, he ensures the telescope is a good example and performs as it should. If he finds it is not then he will correct the alignment/aberration on the bench. If this is not possible the telescope is rejected. Think of it as an additional layer of quality control. We don’t provide a certificate or report. 

Regarding the flattener, that isn’t normally included but if you want it tested please email us your request and we’ll see what we can do.

Hi Steve, just placed the order for the scope and flattener (plua a ZWO OAG). I have add the request for the verification with the flattener. Looking forward to get it here.

Hi,

I have found this thread while looking for more details on the Es Reid tests on offer with the Esprit scopes.

I have seen the summary description of the procedure on this thread, thank you.

I would have a couple of further questions.

What is in the test report? Is it a declaration (e.g., comformity to certain reference parameters)? does it include images (e.g., from the Ronchi test or of artificial sources)? Interferometric results?

If I buy the scope with the flattener, is there also a test of the telescope with it?

Thanks a lot.

Hi Dave, you actually helped me quite a lot! the suggestion to use Internet Explorer was a very good one. In fact, the pages that were very slow to load with Mozilla, were much easier to access and I finally found some important info.

https://nikonhacker.com/viewtopic.php?f=2&t=2654

were it says that with the menu based option, BYN may not work but it does with the other option.

Since I use a D7100 for daylight photos, the D5100 will be dedicated to AP and the permanent true current would be fine.

Kind regards and clear skies!

Hi, is there anyone who have/had a software patched D5100 that could help with my question?

Thanks!

The problem is that the Nikon hacker web site seems non updated since quite a while and I do not manage accessing the forum pages. So I was trying with google but found nothing so far. Yet, I think I saw some comment once but can't remember where and what the conclusions were..... Thanks anyway.

Hi everybody,

I just got a second hand D5100 (with firmware version 1.01) and I want to patch it with the Nikon hacker software patch 1.20.6.

For the camera and firmware I have, it gives the possibility of choosing one of the two (either one or the other) options:

BETA - True Dark Current

BETA - True Dark Current - Menu based

I have been trying to find comments/opinions on which one is advised, but with no success.

In theory, it should be the same and, in principle, the second should be better as you can activate it at your whish.

However, in real use there may be glitches that I would like to know ahead of time.

Also, but less important, if someone knows what the differenece between

Video 1080 HQ 54mbps Bit-rate

and

Video 1080 HQ 54mbps Bit-rate NQ old HQ

is (that is what NQ stands for), I would be very grateful.

Clear skies to all.
