I was finally able to capture Juno last night.  I found a nice asteroid finder site: https://asteroid.lowell.edu/astfinder/.  Here is a screen capture of the location of Juno at the time of my observation last night:

Here is my capture of the same area of sky.  I centered my goto on 45Tau (HIP 19554).  5x4 sec, 300 gain, rotated to match the finder chart.

Had another go at NGC1514 last night, this time with a 6.3 reducer on the C8. Observing conditions where poor and I had to push the histogram into some very noisy territory to get any detail. The complex shell patterns within this PN were likely caused by a companion orbiting the primary star and initially I made the newbie mistake of thinking I had resolved this smaller companion - but sadly no, doing my homework this morning it seems that the pair is far too close to split optically, having a ~9yr orbital period

 

~100 x 13s exposures @ 395 gain:

Took another shot at NGC2683, UFO Galaxy. Removed the focal reducer on this attempt. Omni XLT 150 (N), ZWO ASI224MC, CG-4. 61 five second exposures at gain 250. Still learning.
 
Also took 300 twenty second exposures at gain 100 and post processed in Pixinsight, those images are in my gallery.
