    Sal, 2024 December

    Hello everyone, I was able to spend nine days at Sal end of 2024. Before the vacational trip I try to gather information about the birdlife in general, and many thanks to members who shared experiences from this island here. I managed to see 26 species in total, spending not too much efforts...

    Kowa TSN 1 SLR adapter? Anyone used one?

    Hello, It is a resized, cropped picture with Pink-footed geese, made in zero light with TSN-3 and Nikon D7100 50mm f1,8 in Oudega, Netherlands last November.

    Kowa TSN 1 SLR adapter? Anyone used one?

    Hello, I would not expect any excellent outcoming with that combo. TSN-1 is not a fluorite scope, so chromatic aberration is high using a camera on it, but the view will be O.K. with naked eye. Try TSN-3 or 4 with fluorite lens, that is O.K. with DSLR and basic objective (50mm f 1,8) for...

    Anything new on the horizon?

    I am sure that is not a pure speculation. Everywhere are discounts on the 773/4 and 883/4 models, as on eyepieces as well. I bought now a TE-9Z for my old Kowas less than 300 EUR with postage fee and taxes.

    The next Alpha technology - electronics will be the next frontier for alpha glass

    I have seen an article seven years ago, that the next big thing with optics will be to incorporate electronics, IS, etc. in the next five years. :-) Nothing happened. The explanation is quite easy, that is my opinion: those equipments are too expensive to spread widely. Just check, what is about...

    Alternative to the TE-9Z zoom on the 663M?

    Hello everybody, I need to add a corrigenda to my previous message. I managed to add the Baader Hyperion MK IV zoom eyepiece to my Kowa TS-614 AND reached the infinity. I used the Baader-Hyperion 41,5 mm wide zero-lenght reducing piece...

    Alternative to the TE-9Z zoom on the 663M?

    Hello, I made the measurements on my Kowas. Please keep in mind that my old TSN-4 is with protective glass before the prism. The two bayonets are considerable similarities but differences too. The same time I made measurements on my Baader Hyperion MK IV zoom nosepiece also. It has a 19 mm...

    Alternative to the TE-9Z zoom on the 663M?

    Hello, As soon as I have some free time, I will make measurements on my TS-614 and TSN-4 and I will reply. Cheers, Vámi

    Alternative to the TE-9Z zoom on the 663M?

    Hello, No, that was an another post/thread. I remember because I made the same cut on my Baader zoom with the same cutting tool, but even with that shortened lower barrel, the combo of mine did not reach the necessary deepness. I think that the secret hint would be the dremel tool + griding...

    Alternative to the TE-9Z zoom on the 663M?

    Hello, I tried it, on TS-612 and TS-614. I did not have success to reach absolute infinity (I means: with a genuine Kowa eyepiece you can reach infinity AND some plus tours with the focus knob); the infinity is reached at lower magnifications, but with high mags, the limitation of sharp...

    Bader hyperion mk1v with Kowa TSN 823M

    Hello ranger4, I faced the same problem with my Mark IV Baader Hyperion Univ. Zoom and old Kowa telescope bodies. Following jackingreen's instructions (who managed to join an Hyperion zoom and a kowa-ts613 body with DIY adapter), however, I was able to do the same with my Hyperion zoom and Kowa...

    Opticron IS 60 ED WP broken body

    Dear members, Have you seen anything, like this, on attached photos, previously? This is a gently used, well kept, not old little scope, but its body broken into two half. The telescope was always put on ever-ready padded case (from the same brand), used mainly to watch birds on feeder from an...
