Adam Y Posted October 31, 2022 Share Posted October 31, 2022 Just wondering as I try to get my head around collimating my SCT (or at least checking it) - seems like taking the scope outside and dealing with all of the extra variables such as the atmosphere, tracking, dew, etc, it would be preferable to keep it indoors or at least do it outdoors during the day. Would a stationary light source a fair distance away be a suitable surrogate for a star? Say an LED from a battery charger or such, sitting on a fence and defocused? Plenty to read here about the laser collimators - I guess that would be one thing to try, though that seems to have enough of its own variables such as is the collimator collimated? Slop in the eyepiece holder, etc. Interested in everyone's thoughts. I am learning to use the tracking, but I don't trust it enough at this point to make adjustments to the optics. thanks!
