M45 taken with my DIY 6" F4 newtonian

[LT]

Except mirrors, all were made by me. However, the original OTA is still too bulky to be transported to overseas for astronomy. Moreover, the MPCC3 doesn't correct the coma aberration so well. So, I need to rebuild the OTA and tailor make a focuser for installing Vixen's corrector PH and 1.4x extender PH on this newtonian for better correction on coma. The work is going on, and hopefully, it can be finished soon. Then I can take that combination of "AP + 6" F4 travel newtonian" overseas for astronomy, both visually and photographically.
