welcome to the Sun Mike! Loads happening in each image.
To clear the pst "hot spot"
- apply a curves adjustment-layer and pull down the curve the required amount.
- Now "ALT click" on the mask of the curves layer (the white icon to the right)
- fill the mask with black (use the paint bucket) to hide the effect of the curves
- "ALT click" again to see the image
- now select the paint brush tool and make its colour white and "paint in" the curves effect in the hot spot
- changing the opacity adjusts the amount of the curves effect
Now unfortunately that PST looks like it may be astigmatic as the image seems a bit soft. The prism in the focusing mechanism is held on by whats effectively "pritstick glue" so goes out of alignment easily. Theres info on the www on how to fix it. best test is to use as high a power as the seeing will take and see if the image will "snap" into focus (as they do with your top quality planetary images!).
Hope this helps
DG
