Takahashi Epsilon 180

This is my latest setup. I spent more than half year to complete this setup. I received the OTA and the yellow finderscope. I hope I can go out to evaluate this yellow OTA anytime soon. It won't be disappointed.

Vixen AX103S

 

This is Vixen AX-103S (f/5.6 with x0.7 focal reducer), 4-inch apochromatic refractor from Vixen. Unlike an achromatic refractor, whose objective consists of two optical elements, it has a three-element objective. The central lens boasts extra-low dispersion (ED) glass designed to reduce chromatic aberration (colors focusing at different points) and improve image contrast. Also, a fourth optical component in included as a field corrector lens positioned toward the rear of the tube.

Celestron C11

This is C11 made by Celestron, which is my first Schmidt-Cassegrain. It was coupled with Losmandy G11 can be seen in the picture (Left black tube). Now, it is operated with Vixen SXD since G11 was sold. I think G11 performed much better than SXD regarding handling C11. But, it doesn't mean that SXD can't be used for C11. As of now, C11 has been used for a visual observation. Well, I might be able to do astroimaging with a stock condition. But, it would be difficult to image deep sky objects with a long focal ratio (f/10). I would rather do astrophotography with Takahashi e180, f/2.8 or Vixen AX-103S, f/5.6 with x0.7 reducer.

TEC 140

This is my first refractor TEC140 in the US. I had have a couple of refractors and reflectors back in South Korea. Now I found that this is an amazing instrument, not compatible to others. It took 8 months to receive it. In the second picture, the TEC140 is installed onto a German equatorial mount Losmandy G11. However, I finally decided to sell it to raise a fund for a Takahashi EM-200 Temma2M.
