Re: Nova in Cassiopeia

I've attached an image showing what's what. The bigger blue circle is 6.2° ... You left off my neighbor's trees. Unfortunately, Cassiopeia is too low in the northwest for me. I went out again at 5:00 AM, but it had not come around on the east yet. It is only Autumn and early Winter for me from my b...

Re: Nova in Cassiopeia

Thanks! I got a BAA news flash first, but the SPA news has been better. I could tell by the RA and Dec that it was close to M52 but I have not tried to find it yet. Tonight is clear, in fact.

Re: What to look at?

(1) I have turned to double stars. Many stars that appear as one the naked eye resolve into two (or more) with a modest telescope. (2) The planets are all easy to find. Mars, however, often disappoints people because of its small size in any instrument. However, even with a small telescope 100 mm (4...

Re: An Online Class in Astrophysics

Through a YouTube channel created by a maths boffin named Tibees, I found this. She misidentified it as a final exam in astrophysics. It is merely plain old astronomy, which, apparently, at MIT is astrophysics. https://ocw.mit.edu/courses/physics/8-282j-introduction-to-astronomy-spring-2006/exams/fi...

Re: An Online Class in Astrophysics

Quote: The grading system is simple. Each video is followed by several quizz, either multiple choice questions or questions requesting a numerical answer. In most cases it is possible to try 2-3 answers before giving the final answer. You qualify for the certificate with at least 50% of correct answ...

An Online Class in Astrophysics

I recently completed an online class offered by the École polytechnique fédérale de Lausanne through edX, a program created by Harvard and MIT and now involving many other institutions. I recommend this class with serious reservations. If you want a structured experience in learning astrophysics on ...

I’ve had a very pleasant, if slightly chilly couple of hours observing with my 66mm William Optics refractor, combined with a 38mm 2” eyepiece. ... I spent a bit of time observing the Andromeda Galaxy, the Cheshire Cat asterism in Auriga, the Hyades, and the Pleiades. I also caught up with Uranus, ...
