sun query

I took some images of Tuesday's transit, could some please advise the
following, on the right handside of the images is what appears to be some
form of 'disturbance on the sun, shows as a fussy mark, as the image was
taken with my digital camera mounted on the telescope WITH sun filter in
place, is this mark actually on the sun or possibly from the camera's ccd, I
checked the filter and that is clean (as well as brand new)
Its my first solar image so not sure, hence my query, any guidance very much
appreciated.
Tried to post a copy of the image but I keep getting an error message

Regards

Richard

It could be a sunspot, there were three or four visible in a modest
'scope on the day. It might have been dust though, it's impossible to
say without seeing the pic.

The reason you can't post the image here is that the group isn't for
binaries (ie anything but text) and your ISP has blocked you from
posting attachments to this group. The usual procedure is to post it
on a website somewhere and give the URL. If you don't have any
webspace email the pic to me and I'll put it on mine and post the URL
here (replace the [groupSexWithoutTheY] in my address with "org").

My last .sig was rubbish too.

Possibly you captured faculae which look like a brighter patch on the
surface of the Sun. see http://www.eaas.co.uk for images an see if you can
see the disturbance you talk about.

You could post it to alt.binaries.pictures.astro. There's also a Web
mirror at www.mysky.org.
Put ASTRO: as the start of the subject line there - it's a convention
that helps keep out spam.

Yup, that's faculae. For more info see the website below.
