Over the weekend I finally got my Vixen Super Polaris OnStep conversion working. The sole purpose for this project was to do EAA with my lightbridge mini 114. Until now I did not have a tracking mount so I was limited to wide field EAA with short f.l. CCTV lenses on a fixed tripod (still very fun). Now with the telescope I can can explore a little deeper and study individual objects.
The resulting fov of the 114mm x 450mm f.l. scope paired with the RT224s 1/3 sensor is pretty utilitarian (~0.6°x0.4°), a little small for the big stuff and a little big for the small stuff, but all around good. For my fist foray into telescope EAA it went very well, little to no frustration.
Here is Andromeda M31 5000Gain 4s 25frames 200s
Words can't describe how thrilled I was to see the gritty dust lanes in such detail in a matter of seconds. I can't wait for the future galaxies to come!
After taking a good long stupefied look at Andromeda I pried myself away to visit the Orion nebula. I had some configuration issues with my first test of OnStep that night, and I had to find the nebula manually. I had the camera set to max gain and 1s exposure for star hopping/framing when the big beautiful full color nebula appeared on screen, I was not expecting that kind performance from the scope+camera combo. The framing shots themselves were beautiful, but I started playing with the live stack.
I had a lot of fun with this one; I was changing the exposure between 2, 4, & 8s during the stack to approximate an HDR effect.
I think it helped.
M42 5000Gain multi length 124s total
I still can't believe this isn't a google search result...
While I was in the area I tried for the horsehead nebula. I had to star hop slew to get it in frame, but I love star hopping so it was fun.
HorseHead 5000Gain 8s 45frames 360s
With the wide field cctv lenses I was able to detect the "dark tombstone" at a tiny image scale, but now with the little telescope I can definitely make out the detailed shape. Incredibly cool!!!
I can't wait for another clear night.
