Sonnenbeobachtungs-Workshop mit Schülern, eine Station von sieben=Solarscope
Beginnen wir mit dem Negativen - der deutschen Übersetzung der beiliegenden Anleitung - die ist so schlecht ausgefallen, das könnte sogar Google Translate besser. Zum Glück sind die Abbildungen klar und verständlich und somit schafft man das Zusammenstecken der Kartonteile auch mit Hilfe der Abbildungen alleine recht flott.
Eine bessere Lösung zum Scharfstellen der Sonnenprojektion ist ein Vorschlag für die Zukunft dieses Produkts, die Klemmung mit Hilfe kleiner Rillen auf dem Abbildungsfernrohr fällt zu grob aus, in meinem Fall wäre die beste Schärfe zwischen zweier solcher Rillen gelegen.
Das Abbild der Sonne ist 12cm groß und so entsprechend große Sonnenflecken vorhanden sind, kann man diese auch wunderbar erkennen.
Hello, I already have one of first version of the Hyperion zoom (there's only written Hyperion 8-24mm Clickstop-Zoom (Phantom Group Coated)) and I want to ask you: can I use it in pair with a Mark IV or III with a binoviewer..? Or should I avoid because of different size of the barrel...or different size of exit pupils ? Thank you very much for your answer and attention. Saluti
OPFA-3 for Celestron 2" SC-Thread #2458143 can be attached directly onto the 2" SC-thread on the back of all Celestron Schmidt-Cassegrains.
OPFA-2 for 2" eyepiece clamps #2458142 fit's into all 2" eyepiece clamps and is the probably the most versatile option.
OPFA-1 for 1 ¼" eyepiece clamps #2458141 fits into 1.25" eyepiece clamps.
If possible, we'd recommend OPFA-2 (easier handling, sturdier than a 1.25" eyepiece clamp) or OPFA-3 (the sturdiest version, holds even heavy cameras safe, but has to be screwed onto the telescope). OPFA-1 and OPFA-2 should only be used with good eyepiece clamps which have a sturdy clamping ring instead of only one simple clamping screw pressing onto the eyepiece/OPFA.

The 2", 24 turns-per-inch thread does not appear to be a standard thread in any of the UNF, UNC or Whitworth lists. All threads have dimensional tolerances (permitted dimensional deviations). The standards, such as ISO 965 for metric threads or ASME/ANSI B1.1 for Unified National threads, specify these. How are the permitted dimensional deviations defined for this product please? My reason for asking is that I want to be very sure that £2000 worth of camera equipment held in place by this product will not fall off. The consequences could be serious.
We do cut this thread according to the Celestron directives which are not to be published. We are authorized Celestron Distributor since 45 years and please be restassured that we know how to cut that 2" thread - as long as it will be fitted onto a Celestron-OTA.

That’s great, thank you. My adaptor arrived this morning and I have attached it to the telescope. It works just fine, does not “jiggle” or “wiggle” and I applied as much force as I dared to try to pull it off. It didn’t even almost pull off.
I am pleased to hear that you and Celestron have shared a detailed specification. I don’t need to know what’s in it. The fact that there is one is enough to reassure me.
Thank you very much.
