Utility of Meade 6.4mm SP in ETX-90ECPosted By Richard Neumann |
I'm a new sky gazer thinking of adding a Meade 6.4mm SP for my recently purchased, used ETX-90EC with 884 tripod. I have the Meade 26mm SP, a Meade 18mm SWA, and 2X barlow. The 26 doesn't provide decent views of mars or saturn. The 18mmSWA is much better, but I want to get shaper, more detailed images of planets and inside moon craters. Is the 6.4mm too powerful to be useful with this scope? Is 2X barlow use out of the scope's limits with the 6.4mm? I often use the scope in remote desert areas of S. California, which have very dark, clear, and seemingly stable atmospheric conditions. Also interested in filter recommendations, specifically a 30% polarizer and #8 yellow, #80A Blue. Thanks for any feedback.
