- My Meade ETX-70AT with Autostar Solar+Star
return to <ETX-70
I've acquired the diminutive Meade 70mm aperture f/5
refractor with goto pointing and
am enjoying the experience. These images show the amazing stellar
penetration and detail possible from such a small telescope aided by
sensitive superfast download USB2 Starlight Xpress HX516 and MX916
monochrome CCD cameras. Typically NO FILTERS are used and recently the
ETX-70 has been piggybacked on my LX200 for better tracking. These
images are a record of my progress over recent months.
