Sun proms
Hi Graham, Thanks for message.
I used 1/200 sec at iso200 with a canon 550d camera - with a f2.8 50 mm lens on. Attached to a Baader eyepiece (17 mm). i.e. Afocal method. This produces an overexposed image (needed to show up the proms). Processed from raw in iPhoto (MAC) and GIMP. You could also use any other method to get image but key to success is processing. You need to experiment with your setup. Once you have it worked out it only takes a few minutes to process. Hope this helps.
Cheers,
John W.
