About this image

Close-up of Ar3038. First ever image of a sunspot using this old achromat refractor which I modified specifically to be a white light Solar Scope.

- deep black velour internal tube lining (improve contrast)

- electric Crayford focuser (improve focus)

- Narrow Band solar continuum filter (Improve contrast - eliminate chromatic aberration)

- Baader Herschel Wedge (Improve contrast)

The seeing was very very poor so I hope to get better image with better conditions
