collimation: artificial star vs street light 1.5 miles away

#1

Post by psy1280 »

I just ordered the Hubble artificial star in order to collimate, however, I just read where one person was using a street light two miles away. I do have a radio tower with very bright red lights on top that's at least 1.5 miles away (I live on a hill), which would be best to use for collimation?

Thank you for any advice,
Joe

In my experience for my scope, the artificial star works great for collimation but it's rough collimation.
For me the artificial star was a great way to practice collimation and get it right roughly. Used a bright, artificial source a mile away after that and that gave a bit finer collimation after that.
But in the end it really is finetuning with the real deal: a bright star and a startest.
