Still having fun, Po’ Boy style… The lunar images presented here were taken last night through my Sky-Watcher Evostar 150ED with a 59 dollar astrocamera (Svbony SV105). The one taken of the Messier craters region shows the Messier craters well but the “trailing craterlett” in the rays appears more as a “contrast feature” than a craterlett in the shot. This trailing craterlett was clearly seen visually as a crater with a very short rim. Both photographed regions visually were very “crisp” at high power revealing a lot more detail at 375X than I could photograph with my inexpensive astrocamera. The Torricelli region has a myriad of small crater pits that didn’t show in the photo. I also noted that there was no false color on the moon, in the shadows or on the limb, seen with these old eyes at any magnification.
My zonal measurement tests confirmed my star and ronchi tests. The first set of measurements had an average result of 0.0015”. The second series was 0.001” and the third came in at 0.0015” again. At F/8, that averages out to 1/8th wave (0.0013”) using the Ernie Pfannenschmidt method of spherical aberration measurement. The numbers made me chuckle to myself in the dark. Excellent spherical correction!
I believe I have shared enough here and may have worn out my welcome. If so, forgive me. I’m not trying to hijack this thread. I’m just happy having this level of refractor performance without leaving a sink hole in my bank account.
So… anyone else having good results using their Evostar 150? Please share!
Very nice, however I'm interested in seeing a similar shot under a 75% - 80% Illuminated Moon. 25% isn't much of a test (for CA) IME.
