I've gone a similar route, but chose the Redcat 51 over the Askar. I couldn't be happier! It is SO portable, VERY VERY sharp, built in tilt adjustment and a Bahtinov integrated in the cap. Happily rides on the EQM-35 GOTO mount also - doesn't even know it's there. Definitely wide and fast enough for me and the ASI533MC (using an l-eXtreme filter too)
Love it. Sold my Taks, enjoying portability and simplicity.
(yes, I swapped the red vixen bar for a silver one - didn't want to mar that lovely Redcat bar
)
