Finally had a clear night here in NY, so I was finally able to attempt some imaging with my new baby.
I went last night (Sun 3/17) to my imaging site on Jones Beach LI. Unfortunately It was very cold, the moon was at 89% illumination and the winds were higher than the weather report had indicated. My goal was to get the moon and Orion using the .7 focal reducer that ES had loaned me to see if it worked with this scope. I was using the ZWO 294mc and my buddy was using my ZWO 183mc on his ES 80mm scope on the Horse Head Nebula.
I was able to get the image below of the moon thru the ED140. The view was stunning to say the least. My buddy agreed that it was gorgeous thru this scope. I am unable to find any false color in this image. The crater edges and the edges of the moon itself are aberration free to my eyes, but you be the judge. I am including 2 different processes of the same image.
Next, I wanted to get a couple of hours on Orion with the .7 reducer. unfortunately my buddy had issues on his laptop with the ZWO 183mc. I was able to resolve the issue but had lost precious time. I finally slewed to Orion and started to attempt focus. I tried for a half hour to get into focus, but was unable to get the trapezium stars to become pinpricks and split. There was a bloating that I was unable to eliminate in the stars. I was using the specified 55mm back-focus (17.5mm for the 294mc, a 30mm spacer, and 6.5mm from the reducer using the 2" adapter as per ES website)
After all of this Orion was too far in the west and I would have to use the reducer for such a huge target, and wasn't having any luck. Between the wind and the cold and the moonlight from an almost full moon, we decided to pack it in around 10:30pm.
After some discussion with my buddy, we were both pretty sure that the reducer's backfocus may need to be adjusted to be optimal with this scope. I will try to determine the proper spacing in the next week or so. There were no issues with the scope visually and was sharp as a tack on the moon and Orion, so I will need to experiment more with this reducer before I make the determination that it won't pair with this scope.
As an aside, I bought a Polemaster for my Atlas mount to get better polar alignment. It was first light for this camera. It worked flawlessly... worth every penny for the precise PA I was able to achieve. It was so easy to use it shocked even me. If you've been considering one, think no more and get one, you won't be sorry. Amazing product.
Still trying to get the optics report and will be trying again to image soon as the weather becomes more agreeable. I'll post any info or images I get. Clear skies all!!!
