When I tested my Kenko 60mm f/9 refractor with 0.5x reducer, I was disappointed to learn that I can't reach focus even with the focuser barrel fully traveled in! It was almost close to focus maybe another 10mm further in :(
So I have no choice but to get a super short profile 36.4mm to 31.7mm (1.25") eyepiece holder which the Borg #7314 adapter can provide me. My original 1.25" adapter length is 39mm compare to the Borg's 8mm length. Since I need only maybe at most another 10mm inner focus travel, the extra 29mm allowance that the Borg adapter will provide me will surely give me the needed distance. So now.... It's waiting game for next clear sunny sky ...

Lunar Imaging Session - February 10, 2017
Full Moon - February 10, 2017 . Taken with Samsung S7 Edge handheld afocal shot with Televue 8-24mm zoom lens set at 24mm on TV-101 refractor. 1/250sec exposure at ISO 100.

Solar Imaging Session - February 9, 2017
The sky this morning is clear and seeing condition is good. I change my imaging configuration once again and use my Canon EF 100-400mm f/4.5-5.6 IS L lens set at 400mm instead of the Kenko 60mm f.9 refractor to test a favorable compact solar imaging and visual setup that I can use on the ALP free public viewing session on February 12, 2017. Also on this setup for visual, I can use my star diagonal directly on the Daystar Quark Chromosphere Ha Filter with the Canon EF100-400mm L lens set at 400mm to view the Sun full disk with a Celestron 32mm Plossl. Contrast is not bad as well.
Small AR2634 Sunspot Group is showing off this morning by producing M flare from its core structure! There is also a nice large eruptive prominence that is visible in the NW limb.

Lunar Imaging Session - February 7, 2017
The sky this evening is clear but seeing condition is poor. With all my astro gears transferred to our new place, I only got a flimsy 60mm f/9 refractor on a lightweight Nexstar mount to image the Waxing Gibbous Moon with my ZWO ASI120MM Webcam. I test shot one with 0.5x reducer while the other image using the standard webcam resolution.
Image is fair as I'm not expecting this scope to perform better than my trusty TV-101 refractor which I will start using again when we completely transferred officially as still lots of stuffs to moved out and test throw away.
Solar Imaging Session - February 7, 2017
The sky today is cloudy and seeing condition is poor. I was only able to glimpse the Sun for a few minutes before clouds and roof obstruction ended my short session. Anyway, not much action today. Hopefully tomorrow will be better.

Solar Imaging Session - February 5, 2017
The sky this morning is clear and seeing is good. AR2632 Sunspot Group is near the NW limb already and should be out in a day or two. There is also a nice large eruptive prominence in the SW limb as well. Unless there is a new sunspot group coming out of the eastern limb. It will be again be a very quiet Sun this coming week :(
Solar Imaging Session - February 4, 2017
The sky this morning is partly clear but seeing condition is still poor. AR2632 and 2633 Sunspot Group are showing some flaring activity inside their cores while AR2632 also shows a nice dark filament coming out of the group.
