The Sun taken through my solar filter this morning 22/6/18 at 11.30am. After a couple of weeks with no sunspots visible due to the solar minimum, it's nice to see a couple of sunspot groups. The central group is designated as 2115 and the group upper right is designated as 2013.
 
This is a stack of 28 images stacked in Sequator and processed in Photoshop.

Here is my effort taken with a 60mm Lunt Solar Scope and an Altair GP Cam on 22nd June at 5.30pm and tweaked with Gimp. Still haven't figured where I am going wrong. The camera always has the objectional black dot on all images of bright objects as well....Dave

The black dot is almost certainly debris in your image train. A careful but deep clean is the only way to get rid of it. It runs in my mind that on the day you took your image, the solar disk was devoid of any sunspots.
