    Kowa 99 Update?

    Sorry for my mistake. It was supposed to be 180x with 2 extenders. Counting is quite easy. The Kowa 99a offers a max magnification of 70x with the TE 11. One 1.6 Extender will blow it up to 112x, a second, stacked 1.6 Extender will push magnification to 179,2. As pointed out above, a third...

    Kowa 99 Update?

    @DRodrigues: I cannot answer that question because I do not know which part the iPhone's camera plays. What I can say is that watching with two extenders stacked is much more difficult than with just the TE 11 because of the absolutely small exit pupil.

    Kowa 99 Update?

    A lot of rain coming, so I had to be fast in the cold outside (4° C). So here's the second series without any adjustment in the iPhone 13 nor cropping of the picture in Mac "Preview". The 99a was angled at about 30° upwards. I wanted to get off that porch with its vibration and inevitable blur...

    Kowa 99 Update?

    @DRodrigues: you are certainly right that using the iPhone's zoom factor is not helpful in such a comparison. But what I can say is that the second last photograph was made with the TE 11 at full zoom plus one Extender 1.6 and the last one with the TE 11 at full zoom plus two Extenders 1.6. I...

    Kowa 99 Update?

    Thanks @Tringa45 for the nice comment. At almost 74 my interest in all my hobbies (music, photography, astronomy) is slowly but firmly fading. The iPhone can take 180x with daylight situations, but my eyes can't. In other words, I don't enjoy watching at this rate of magnification. Having done...

    Kowa 99 Update?

    I've just done a series of comparisons. This is not a scientific approach and far from the theoretical discussions above. I'm just an amateur who likes birding and photography, that's all. The object was a transmission tower about a mile away from my home. The sky was overcast, and there was no...

    Kowa 99 Update?

    @Tringa45: thanks for the helpful explanation. I only read about the formula (openingx2) somewhere and never really worked with high magnification, neither with the 883 nor with the 99a. Rarely do I employ one of the two Extenders I bought over the years. I once tried using both extenders on the...

    Kowa 99 Update?

    I sold my 883 and bought a 99a in January 2022. I had compared my 883 to a 99a outside the shop in rather poor winter light and found the 99a better for my old eyes (then 71) because of the larger opening. I compared both scopes with the TE 11z I owned and the TE 80 which I later bought because...

    Two Wood Pigeons (Try to Sit on This)

    Just saw this pair of wood pigeons on a dry branch of a plum tree in our garden and my first thought was "try to sit on this".

    This pair of linnets is nesting in our garden. The male linnet is watching while the female bird is in the nest.
