Hi, I’m Ian and I live in Surrey in the UK.
After 3 months of waiting my Sky-Watcher Esprit 120ED it finally arrived in early December. Even better it was a clear evening for a couple of hours that night so I managed to get some first images done and again on the 6th and 10th of December.
I am extremely impressed with this telescope.
I promised to do a more detailed video on how I set-up my first three nights of imaging. So, in this video I will show how to connect elements for visual observation, and how to set-up for a DSLR or the OSC camera I use. I’ve not done DSLR with this telescope yet, but I have used by ZWO ASI294MC Pro OSC camera and you will see at the end of this video a really nice image of the Elephant Trunk Nebula taken with this telescope and camera combination, using the Optolong L-Extreme filter and playing with the colour channels in PixInsight.
