Another 10” Dob For Sale
« on: May 03, 2018, 12:53:08 pm »
For Sale! My Home Built 10” f7.6 “Planet Killer” Truss style Dob. The mirror started out as f5 with a bad figure, so my friend who has been refiguring mirrors for 40 years refigured the mirror. It’s slightly under corrected but it's better to be under than over as a cooling mirror is normally pulled toward over correction so it tends to offset at night as the mirror cools down.
I had Spectrum Coatings in Deltona, FL do the coatings, https://www.spectrum-coatings.com. I chose the “MaxR Coating” with 98% reflectivity. Also included is a low profile 2”/1.25” dual speed focuser, custom made light/dew shroud and a dew heater for the secondary mirror (not installed). I really don’t use it much anymore and I need the space in my condo. $300.00. Thanks, Jim Mack
