John Posted August 8, 2020 Share Posted August 8, 2020 AR12770 has a nice little spot associated with it. Interesting shaped umbra at the moment enclosed in a well defined penumbra and worth a look if you fancy it The other two AR's listed currently (12769 and 12768) don't seem to have spots visible just now. Some extensive faculae complexes in white light though. I'm using a 90mm F/11 achromat refractor and the Lunt Herschel Wedge today 7 Link to comment Share on other sites More sharing options...
laudropb Posted August 8, 2020 Share Posted August 8, 2020 Hi John. Yes it is a lovely spot. First clear day for almost a month. At last I have been able to try out my Solar Quest Mount and my new double stack on my Lunt. I will write a report later on my opinion of these. 6 Link to comment Share on other sites More sharing options...

laudropb Posted August 8, 2020 Share Posted August 8, 2020 Yes David it might be or perhaps the lack of clear skies was due to the curse of .purchasing new equipment 1 Link to comment Share on other sites More sharing options...

Superb, substantial prom today, though double stacking may not be an advantage for that, depends on individual etalons. But active regions still showing nicely in DS, and a couple of small filaments. 1 Link to comment Share on other sites More sharing options...

That zoom, sometimes combined with the 2.25x barlow, is probably my most used eyepiece day and night, except when the 12 inch dobsonian is in use. On it's own for solar it gives 47x - 139x with this scope. A very useful range I'll probably wear it out in due course and have to buy another !

Geoff Barnes Posted August 10, 2020 Share Posted August 10, 2020 Something of interest to all you solar observers, a light bridge seems to be appearing in sunspot AR12770... 1 Link to comment Share on other sites More sharing options...
Alan White Posted August 10, 2020 Share Posted August 10, 2020 (edited) Its split further and is 4 defined areas and perhaps a fifth one. I include a poor sketch for reference, observed in WL using the Vixen ED103. The sketch is better than the scan does justice to, honest. Oh first daylight for the Pentax 10 mm XW, super as expected Edited August 10, 2020 by Alan White 2 Link to comment Share on other sites More sharing options...
