ETX 90 OTA Test 7/1/17

Despite very poor seeing, I decided to put the 90 OTA through its paces. The results are not bad--I'd like to try in better seeing.  Here is the moon, taken with the 90, a EQ Pro mount, a Mallincam DS 2.3+ camera and a 2x Barlow:

Although it was like looking through choppy water, this image still has some fairly good detail. Jupiter, however, was a different story:

Here's a crop:

Not much detail is visible, but stars directly overhead were scintillating wildly and the planet was caught in thermals above a neighbor's roof. I'm hoping to try again next week in Michigan where I may be able to image through laminar airflow off the lake.
