Yes, newbs gonna newb. Experienced people are going to say "duh". But for the edification of others, I thought I'd continue to relate my journey. Tonight I had some clear skies starting at about 10pm. I was able to catch Jupiter and Saturn again with the 90mm but not with quite the seeing as last time. Here are some of the things (and some truisms you can find easily by searching the forum) I've discovered for myself as true...
- While shorter eyepieces have worse eye relief, they generally yield a sharper view than a barlowed longer eyepiece. (Amongst similar quality EP)
- Decent eyepieces barlowed have better views than shorter EPs that are cheap.
- Cheap EP look okay until you barlow or get into shorter ones. The first decent EP you buy will make this obvious per the above point. Using a refractor rather than a Dob seemed to play a part in this too.
- My cheap 2x barlow makes everything look horrible. I need to buy a different one. My 3x Astromania is good, tho.
- My $0.99 5x barlow is not bad at all when I put a quality EP in it. Sometimes you get lucky.
- I'm surprised at the amount of chromatic abberation I get at F10.1 on bright objects. Perhaps I am sensitive to it? Stopping down the aperture or backing off the magnification does mitigate this.
The moon is coming up now. Perhaps I will learn something new.
