Description

Only one second per frame in order to get the inner four (actually 7 *) hot stars not overexposed and
separated.
*) there a 3 more stars, very close to the four bright stars - 4" apart -, which I could not resolve yet.
( possible improvements : collimation , no focal reducer , shorter exposure, better seeing cond.)

Question : When looking at the green overlay close to the inner four stars, it indicates a further star
(bottom left to the four) which is not visible in my image. May be it is overcast by the dark cloud.

Has anyone an answer to this question?
