  1. In these cloudy/rainy times I have been spending some time doing this course and am now about halfway through. It is quite enjoyable and gives a general overview of several topics. Although it is not necessarily teaching me much that I didn't already know, it is good to be studying in a structured format and actually producing some written submissions.

    The lectures are easily digestible in up to 15 min videos and are supported by multiple choice quizzes at key points, whilst some subject areas also have the written submission.

    The written pieces are peer reviewed - marked by others on the course rather than in a formal way. I have found this to be fine and fair if you take the time to formulate and submit a good answer. When it is time to review others, the submissions are a mixed bag and I have actually reported two users for quite obvious plagiarism.

    Most useful and interesting is a regular live Q&A session on youtube with Prof. Chris Impey, this has been a highlight for me to put any questions to him about the course or any other physics/astronomy interests.

    All in all, this is definitely worth doing as a first step for adult education and will certainly provide a baseline level of knowledge if you have not completed any other further science education, or as a platform for targeting something more advanced.

  2. Good breaks in the clouds here in Bournemouth but as I'm at work, I just chucked a small pair of binos in my laptop bag with a solar filter.

    Unfortunately the binos are too small to actually resolve Mercury so I'm getting intermittently good views of a golden blob and not much else!

    Will be living vicariously through those of you that are sharing images.

    The mounts look exactly the same there as far as I can tell! Is there any way to differentiate?

    Thanks to everyone again for the responses, all really useful and informative.

  4. So, I'm still relatively new to practical astronomy and only got around to buying my first scope in the summer. I like to research anything I buy to the tiniest detail, so much so that my wife is surprised I ever get around to buying anything. But it seems my research missed an important piece of information here, that I seem to have purchased a bird-jones scope:

    https://www.telescopehouse.com/bresser-reflector-pollux-6-150-1400-reflector-on-eq-2.html

    So far I haven't experienced any particular problems with it but have read recently that this scope design will inherently result in poor views and longer term issues. Is this something I should be particularly worried about in the short term? Likelihood is a medium term plan to get this kit on ebay and pick up a replacement from FLO.

  5. An explanation that hasn't been suggested yet, and possibly the most simple, is that this sighting is the result of an optical illusion.

    We know that physics won't allow the true direction change so most likely this was a 'skim' off the denser atmosphere which was viewed from an acute angle, giving the appearance of a sharp turn.
