Description

Had some collimation issues with my scope and the lack of clear skies over the past couple months didn't allow me to finalize things with star testing, but I eventually got things nailed down to where I am happy with my scope's performance. Also, I tested out a CCDT67 telecompressor roughly around .71x, which reduced my effective focal length from 1625mm to 1154mm. Resolution was reduced from .48 to .67 arcsec/pixel.

Not going for deep here, just wanted to get a good star field to test my optics out.

If you notice an extra set of spikes on the brighter stars, this is due to overhead wires passing through the FOV. Ahhh, urban astrophotography!
