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.
We are very sorry, we only offer the filters you see on our website and there is mentioned that we offer these filters only for Canon DSLR. There are no plans to offer filters for Pentax Cameras because we need to manufacturer thousands of filters at once - and the Pentax Cameras are not common among amateur astrophotographers so that it would not make sense.

Since these filters are optimized for fast systems, will they work as well as the "normal" filters on say an f/6 system that I have now? It would be nice to use these fast filters on the current system as well as a faster system in the future.
Follow up question i dont think my original question was answered. It is mentioned here that you can use T2-15B as an eyepiece holder in a T2 diagonal which then doesn't allow it to freely rotate as you mentioned. This is why i asked if the Lever is adjustable with the screw that you can see directly across from the Lever itself. Please advise if it possible to loosen this to adjust the outer ring position? I realize that T2-08 is an option but it doesn't have the lever!
Thanks for your follow up. You are right, we the female T-2 thread this clamp can be used for T-2 diagonals as you described. However unfortunately it is not possible to reposition the lever here as with other 2" ClickLock clamps. The screw you described is cemented and needed for the ClickLock functionality, it can't be removed.

Making a zoom become waterprove has severe consequences. The designer must decide if he can accept a hard rotation action or not. For use with a spotting scope it "could" have been be made waterproof by fitting O-rings into the rotating mechanics to seal the moving area. However - this does work on a short and relatively lightweight spotter - but the rotation movement of the zoom-action in this case is getting stiff and hard to rotate.
For an astronomical telescope this would be an impossible behaviour because the telescope would wiggle when the zoom-action is so hard to turn - especially in winter.... Also the "Click-function" would become impossible to feel - the whole eyepiece would become "just another zoom".
So - in order to enable an effortless zoom action with the click-stops to be just sightly noticeable (if these are "hard-clicks" likewise astronomers do complain!), we omitted a tight seal in the area relevant for the zoom action. However - as soon as the eyepiece is connected onto a telescope (or spotter), the upper lens parts certainly are O-ring sealed and the eyepiece can justifiedly be called water resistant, because rain will not enter.
At any rate - if you are in need of a completely watertight solution for harsh outdoor use on a spotting scope, this eyepiece may not be a solution for you.

Our company exists now for more than 50 years. In this time, more than 15.000 Baader Planetariums (the first patented product of our company) help all over the world to give students an understanding of astronomical correlations. In our own manufactory, more than 500 observatory domes have been produced and delivered turnkey-ready. Instruments and telescope accessories from "Baader" are known for their high qualities by many astronomers and universities. We consider it our duty and obligation, not only to sell telescopes, but an indivdually selected telescope system, that brings you a lifetime of joy.
