Quote:I am interested in knowing what is the smallest aperture newt,sct and refractors this challenging double can be seen with.
Quote:Last night I noticed that a 6th mag star posing as a 5th Jovian moon is actually a challenging red double star. According to Skysafari Pro it a 5.9 and 8.5 mag double with a sep of 2.0 arcseconds. It took the 16 LB to split it last night in okay seeing. The 8 and 12 inchers were not doing it by the time I realized it was a double on the phone Jupiter was above my house and seeing was down but the Lightbridge was in the front yard and seeing was better there. The star is HR 1370.
.... back yard astronomer ================= Don't forget to look at the moon often. Its a play ground of fun if you throttle up the magnification!
