Re: Solar prom of 7th Jan

Thank you everybody for your kind comments. A hot night last night here in SE Australia with 24°C min and 37°C during day. Very hot due no doubt to the old Sun. Cheers John W.
PS. Hope you folk in the UK are keeping safe.

Thank you James - it took me a couple of years to perfect the dslr images on my equipment. A lot of experimenting to get it right. Cheers John W.

Sun 7th Jan 2021

7th Jan 2021 ...The Sun showed no sunspots today and no large flares. There were however some nice prominences. This single exposure image of the SW sector was taken with a Canon 550d camera attached to a Lunt 100 Ha scope. Thanks for viewing.

Re: 29th Dec Sun images

Thank you everyone for your comments. It is a challenge to take single exposure images with a dslr camera - you don't just put a camera to the telescope and go click. It takes a bit of processing to get the image right. I take all my images (inc. dso) by dslr as I enjoy it. I have tried ccd cameras ...

First two images are at Ha wavelength thru a Lunt 100 Ha scope, the third is thru a WO 81 mm scope with herschel wedge at 540 nm showing the sunspots. Cano...

Sun Dec 3rd

Dec 3rd - Managed a couple of pics of the Sun this morning in Australia - sunny and fairly steady sky. Both pics are single exposures (canon 550d) with the second one adjusted to show the prominences (although they are weak). Both show the 3 active regions on display at the moment with new region 27...
