Quote:I too noticed the slight astigmatism but assumed my mirror wasn't fully cooled as I didn't notice it throughout the night though it's likely my initial view of extra critical and my eye let it go after that as this is something that has never bothered me with any of the other ES 100's. Certainly not bothersome astigmatism.
Quote:On light scatter - this is something I notice with most if not all of the ES EP's so it didn't stand out for me. Since I was viewing such dim objects anyway I didn't notice it. It's most noticeable on Jupiter and the Moon with the rest of the line as well - to the point where I use the light scatter to zero in on the Moon and Jupiter rather than switching to the laser or finder. Certainly problematic if you are not using as a "feature". The brightest object I viewed was probably Saturn and the light scatter was either not noticeable or I wasn't paying attention to it as I can't recall it as I easily do for items like Jupiter (I did not observe Jupiter last night - perhaps tonight).
Quote:On the exit pupil - maybe my 34 year old eyes still easily manage the 6+ exit pupil of the ES30 82 though this will eventually change - this would certainly color my interpretation of the EP's.
All MY reflectors are apochromatic. I am personally covered with infrared detectors and emit at 295 Kelvin, 24/7. If I were to recieve a spin entangled photon before you recieved its twin, MY photon would predict your photon's spin. Every time. MY family's lineage goes back over three billion years and has a whole branch of science devoted to studying it... The most Quotidian of observers
