Hi Folks,

Over the past month, I have seemed to notice that my mount's unguided ability didn't seem quite up to par.  Over the course of the evening, the target would very slowly shift out of the center of the field of view.  I noticed that if I rebuilt the sky model each night for my unguided imaging, it would help, but then the problem would come back.  I couldn't figure out for the life of me how a sky model could degrade so much in one night.

Today, I think I solved the mystery.  I noticed I had to give my wheeley bars extra oomph to get out of the garage.  Tires were all at close to flat!  Reinflated all of them, and I'm astonished at how great the unguided imaging is going so far… smilesmilesmile

Anyone with wheeley bars… check your tires for great imaging lol.

Clear skies,
Ben
