Been a Long Time

As mentioned in my profile, I was for many years active in a wide range of astronomical fields, and one of the areas I specialised in was white light solar imaging-visual observations from 1984 onwards with digital imaging taking place between 2000 and 2006.
With around two years of on-off surgery, the specialised equipment was put in storage, and subsequently the solar cycle  went into a very deep prolonged minimum. Since I saw no point in taking images of blank yellow circles I never got round to dusting the equipment off. I keep an eye on and seeing that there were some interesting sunspot groups decided to have a go.
Had to completely strip the equipment down and ensure every optical surface was clean, and discovered that there were also a few mechanical issues to sort out as well. Still the results were pretty good considering how out of practice I had become.

There is a small amount of cirrus cloud drifting over the disc but the six active groups are visible.

Just to point something out-this was taken with highly specialised equipment designed specifically for solar observations. Please do not try this with ordinary camera equipment, lenses or telescopes as damage to the equipment is a certainty and there is also a very high risk of severe eyesight damage.
