Svbony 3-8mm Incompatible with Lunt B600
The longer insert barrel bottoms out with ~5mm exposed in the Lunt B600. Insufficient inward focus using the Coma Helical. The Coma has a greater in and out focus range compared to the Lunt Helical. Sale price and purchased for Lunar observation. Curious to see how this zoom preforms as a solar EP. Might consider it for binoview use if I like it for mono dark sky use. Not an expensive zoom. Price bounces around from $123 to $149. Decent reviews even when compared to the Nagler 3-6mm zoom. But for solar viewing? Anyone using this zoom for observing the Sun?
