Faint Fuzzies with the refractor & moonlight..

Date: Sept 24th 2009, Thursday
Observation Time: 8pm to 9pm (~1 hr)
Location: SD home
Weather: Okay. Moon 45% illuminated.
Instruments: Celestron Nexstar 80GT GOTO Refractor f/5


Moon: 6th day: Observed with TMB eyepieces + barlow. Overall 6mm, 4mm and 3mm ,2mm were still nice views.. extreme zoom with 2mm @ 200x wasn't sharp and too wavy.. but high zoom indeed shows lot of details and gives a feeling of moon walk.
- Crater Posidonius at the edge of mare serenitatis was nice.. you can see tiny crates inside it.
- The white ridge, Dorsa Smirnov, inside mare serenitatis was visible clearly and showed its existence.
- Crater Plinius central mountain visibile.. seemed like 2 peaks.
- Crater Theophilius, Cyrillus, Catharina seemed to be connected with crater edges on East side.

Jupiter: Yday watched jupiter, today just tried TMB EPs with high mags.. 2mm @200x was bad.. probably 3mm @ 133x was max i was able to push. Jupiter bands were visible...sort of.. really hard to focus because of R&P. Tried red filter too.. still not that clear.. non-filter view is much better and clear.

M28 - Yday i missed this one, and today while just browsing for M22, I ended up on this one. In 32mm @ 13x clearly visible. Fuzzy tiny and sort of visible. With barlow @ 26x shows some detail, surely kills some brightness.. wasn't able to resolve any details.. but just glad that you can see this fuzzy so clearly at @13x though heavy moonlight is present. This must be visible from my binocs.

M22: Visible in 32mm, thought can not fit both m22 and m28 in same view. With high mags 6mm @ 66x shows marvellous views of M22. can clearly resolve the stars. Though moonlite is present, I was impressed with the quality of the image and the resolution.

M55: Tried hunting for M55, but moonlite kills everything. hunting thru 32mm.. With barlowed 32mm shows some vignetting while searching the object. Lil hard to use. 25mm Elux is better to use after 32mm, instead of barlowed focal 16mm.

Refractor GOTO ran out of battery. Seems to be a trouble for long term.
Need to hunt some double stars.

Overall I am happy with the tiny refractor what it can do, considering its limitations.
