Finally AZ-40 and EM31Pro are in stock now.

Player One’s Uranus Pro looks the perfect cameras for the galaxies, especially when used with the super sharp optics. Here is why. Believe or not, the following image was taken through 375mm focal length telescope. Well resolved! And stars are not bloated much even the image frame was cropped.

In general, the scope must be said obviously too small for M51. But how about this? This should result from the small pixel camera and small spot size optics. This proves SJH-75UF performs not only for the wide-field but also for small galaxies.

This outcome really encourages me to try to shoot galaxies through SJH-75UF.

Japan’s BinoTechno proprietary – alignment-free platform allows BORG users to make BINO system ready to observe instantly once setting 2 objective lenses without any user adjustment. Here is the recent Japanese user’s setup.

And my 107FL and 90FL.

This BORG platform works with any of BORG 3″ and 4″ including old ED objective lenses. Quite versatile systems.

This time the strain wave mount was not popular yet. So I did the single fork mount setup. But setting BINO at the top of the mount is always much better and stable.

Star test for SJH-75UF and Player One Zeus-M. Both look good as expected. Since I was using M48 adapter, it might block the light at each corner of the full frame sensor. The scope uses Ohara Japanese plant’s SD and EDs. So it’s fully “Made in Japan”.

ToupTek D60 provided by Astro Hutech is pre-tested at the field. See at

Zeus-M, Poseidon-M and some others including all guide cameras are back in stock now.

Player One special sale will end April 20th. Don’t miss this sales event. More units are on the way. If some items you are interested in are currently out of stock, e-mail to me. I will secure the special prices for you.

eADC3 is back in stock now.

Sunobserver eADC – Electronic Atmospheric Dispersion Corrector V3.0

Our goal was the ultimate pinpoint stars. This has been the core concept since the very beginning of development. Finally the commercial units have arrived in the US.

Following their two D50 achromatic telescopes, this is their first apochromatic telescope – 6-element astrograph. Now it is in stock at Astro Hutech.

I was field testing last night. Indeed, as they claimed, it delivered pinpoint stars from corner to corner, even on a full-frame sensor.

US price is $4,999.00 Yes, no compromise in performance, quality and cost.

See this impressive setup. This mount should be ideal for serious visual observers. The compact and powerful ALT-AZ mount allows a binoscope to be mounted on top, making it perfect for BINO setups as well. It should also be excellent for total solar eclipse observations, as it allows multiple viewing configurations within a limited time of the totality.

The mount and accessories will be available at Astro Hutech shortly.

The current EM31Pro in top mode performs very well for my BINO setup. However, I may switch to the AZ40 in the future, as it is much simpler and more compact—making it ideal for overseas expeditions such as total solar eclipse trips.

Player One NEAF specials begin today.

This special sale is available at Astro Hutech through April 20.
