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. • Timecodes • 0:00 - Introduction • 1:05 - Lens and Dew shield • 3:07 - Visual observation set up • 5:32 - Fitting the Flattener • 8:30 - Fitting a DSLR Camera • 12:55 - Fitting a One Shot Color Camera • 20:23 - Fitting the optional Filter Cell • 24:55 - The Elephant Trunk Nebula • • From Telescope to Flattener • An extension that connects to back of the Telescope with a 74m thread to Focus Tube and 65mm to the flattener end • Optional Filter Cell, 65mm threads both sides, 2 filter fits inside this cell • Flattener • Esprit 120 ED Field Corrector/Flattener, front end is 65mm and camera end is 62mm • Flattener to camera(s) • Extension to fit camera end of flattener at 62mm and camera side is 48mm (optional 2” filter can be added to this extension) • DSLR • T ring for DSLR camera, in my case a Cannon T ring • DSLR Camera • One Shot Colour Camera • ZWO 2 Filter draw (M48/M42), if you used the Filter option above, replace this with 21mm of alternative extension • Baader M48 Fine Adjustment Ring – Aluminum (1mm) • Easy Grip M48 Female to M42 Male adapter • Two x ZWO M48 to M42 adapter insert rings • Astro Essentials M48 Extension Tubes.
