William Optics Zenithstar 61 First Light
Having some mildly successful attempts at astrophotography with a DSLR and a camera lens (and the iOptron SkyGuider Pro), I decided I would make the investment and get the William Optics Zenithstar 61.
Already having the iOptron SkyGuider Pro, the Zenithstar 61 seemed like a logical choice. The telescope, Flattener and T-mount along with my Canon 6D were just about the weight limit that I wanted to put on the SkyGuider Pro.
Here is the setup in my driveway (Bortle scale 6).
Notice that the whole setup was a little to heavy to balance with one counter weight. In a pinch I used a C Clamp making sure to tape down the sliding arm so it didn’t move as the mount followed the sky.
What is shown here:
- William Optics Zenithstar 61 (blue)
- William Optics Adjustable Flattener 61
- William Optics Canon T-mount
- Astromania DeLuxe Dovetail Plate, Vixen 228mm
- iOptron SkyGuider Pro
- ProAm USA Professional Tandem Leg Tripod with 75mm Bowl Mount
- Canon 6D (unmodified)
- Laptop running BackYard EOS
Due to light pollution I was not immediately able to find the Andromeda galaxy, so I took many test shots, slightly changing the alignment until I finally found it.
A few minutes later the Orion Nebula rose above the horizon and I was able to get this
Great learning experience! I learned that I need some type of finder scope or Red Dot finder, how to focus using BackYard EOS, and that I will need to purchase another counterweight.
Next I hope to be able to get out to a less light polluted sight (Bortle scale 4).
Thanks for looking.
