Quote:It's one of the Haas project stars, and observations (successful ones) are currently listed for apertures down to 101mm, which is extraordinary if it's a definite, not a spurious, observation - sometimes doubles look as if they're showing but they're not - honest but spurious observations can happen. The resolution reports have 3 recorded successes with 150mm; that's clear enough as an indication of what's possible. Beyond that???

Quote:I'm not surprized in the least at the problems you folks are having. It's not an orange "bump" either. My 10" refractor shows a white companion hidden just beneath the broken first disc ring. I'm wondering if it is a variable star. It just seems much dimmer than 8 mag. Maybe it's deceiving because of the 5 mag. primary. All I know is it is somewhat "difficult" in my big refractor. I don't see how a 6"-8" scope at high power to seperate 1.6" can be able to detect this little devil. It truly needs exceptional steadiness in the air. Mike

Quote:For me it was a matter of summer haze and light pollution blotting it out. Steadiness in the air was rather lousy quite frankly. Instead the dryer fall-like air it was held with certainty at 364x simply because the sky was darker - transparent. I'm not sure Id hold this double with any kind of elevated appreciation had I mag 6 sky's. as mentioned in a previous post : 2ES Vulpeculi is far more challenging - and under a better than mag 6 sky.5.48-9.28v @ 1.8" versus 90 Herculis: 6.17-8.38v @ 1.6"The 2/10ths greater sep of 2ES hardly makes it comparable. At anyrate I would never contemplate this one from my condos compromised sky's. Pete
“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy.
