The first set of photos of a sunspot was taken with a Leica X Vario and a Sky-Watcher Heritage 100P telescope (sun filter, 32 mm, 16 mm, and 6 mm eyepieces). I held the camera against the eyepiece of the telescope. This technique has been named "1:50 technique," because you have to take 50 photos in order to get one sharp photo...
Below, I also add photos of a sunspot taken with the newly acquired Sky-Watcher Heritage 114P Virtuoso telescope (sun filter, 32 mm, 16 mm, and 6 mm eyepieces)
I took the photos with the Heritage 100P in preparation of the Mercury transit on May 9, 2016 to test the equipment. For this occasion, I acquired an euro EMC sun filter (type SF100, size 5 or 600-105) that fits my Skywatcher Heritage 100P telescope.
The photos with the Heritage 114P were taken on the day it arrived at my home, namely on May 19, 2016. These photos were meant as a first test of the telescope. I also wanted to check whether the sun filter can be fitted to this telescope as well (it can be fitted but the filter holders have to be fitted inside the tube).
This eyepiece enabled me to capture the complete sun
