) light pollution.Anyway Samuel and I was at the Toa Payoh Park for about 1.5hrs. Here are our observations:
M42: Very bright, nebulosity can be easily seen without using filters. At 60x the diagonal splits itself very distinctly, at 150x the diagonal is very big, and I could even push my scope optics to 300x (diagonal + 10mm ep + barlow)!
M45: Couldn't fit the whole thing in my scope view, but nonetheless bright and clear. I love clear skies
M41: This one has always been eluding me! Okay, those were cloudy skies, but I thought I could do better. I got this at first strike. Looks fabulous too.
Saturn: This was blocked by the trees at our usual haunt, so we had to move abit further to a bridge at the pond (Oh no, the water..) But saturn was worth the move, bright, yellowish. Samuel said he could see 2 or 3 moons, but I only saw one :? The image only turned slightly soft when I put in the (barlow+10mm) to bring Saturn up at 300x.
Castor (Alpha Gemini): I remembered that it's a double star! Went to check it out. At 60x, it wouldn't resolve properly (I think because the scope was shaky) and only those who know that it is a double star can see the "line" instead of "point". At 150x the star finally split into 2.
Other worthy things to note:
M78, nebula, as recommended by Samuel (tried but failed today)
Hm, I better do some research before going out again.
