This is my astrobin for the 12.5 Newtonian. The optics are old Galaxy Optics that are in desperate need of recoating and my imaging skills are not great yet with this size rig. The ota is 80 lbs loaded with 60lbs worth of counter weight all being slewed around by a 400 step nema 17 on a 359t worm drive on RA, a 200 step 5:1 planetary nema17 with a 7.1 byers wormgear on dec with tmc2100 drivers at 24v in stelthchop no loss of steps and respectable slew speeds for the size.
