The magnification is depending on the focal lenght of your telescope and the eyepieces that you are using.
If you have a telescope with 1000mm focal length and use a 20mm eyepiece, the magnification is 1000:20 = 50x
When using an Glaspath corrector 1,25 the magnification is 1,25x 50 = 62,5x

Yes - but only for photography! The K-Line filter is NOT FOR VISUAL USE!

Thank you for your nice comment, we are excited too! As soon as narrowband deliveries start, the 65x65x3 mm filters all will be available in all four filter families. At this time we are concentrating entirely on production and marketing of the new narrowband technology - also due to the fact that RGB-filters have a much wider spectral window and imaging results do not suffer so badly when comparing the s/n ratio of CCD-chips versus CMOS-chips.

Eventually we will bring the new coating tech into the field of RGB-filters - but please understand that this still will take considerable time. The financial burden to enter into new technological fields are big. At this time we are concentrating entirely, to show that this new CMOS-optimized coating tech is really as good as our early testers confirmed.

As soon as more people know about this and can confirm it with their imaging results, we hope this will pave the way to extend this tech into other fields. However - far more important than the RGB-filters are both families of photometric filters (SLOAN & UBVIR) which are in demand at this time - to be produced in the same quality grade and "to be available at all". We are working on this very hard and once the community can access SLOAN (u,g,r, i,z-s,y) filters at "down to earth prices" this will also open the field for totally new ways of "RGB-like" imaging, for new optics to work in NIR asf.

If none of the brackets fits, you can always replace the finder base on the telescope with Baader Standard Base - for MQR III&IV, for Witty One & for V-Bracket # 2457000. You can probably also replace it with Sky-Surfer III – tube adapter set made of ABS # 2957303 which is already included with the SkySurfer III.

Unfortunately it is correct that we have not yet produced dustcaps for our new M48 systems. But we see the need for them and plan to include them in the future. It will take a couple of months however to produce them from scratch. Sorry about the inconvenience!
