Yes, all scopes have pros and cons. For a beginner, 80mm is good enough to learn the sky, see the brightest globular clusters and open clusters, bright nebulae, planets at medium magnifications, the moon, the sun with appropriate filter, etc. But of course if LZ has already seen all these, he will not be satisfied with visual 80mm.鄧登凳 寫: 80mm口徑的鏡, 拍攝可用長時間曝光補足, 但目視就會有很多的限制(分辨率不足及看不到暗的星雲)。
Nothing beats a big dobs in visual. My suggestion of EQ5Pro and a 80mm ED refractor is only based on the budget and requirement given by LZ (which is visual + photography).
I agree that for visual observations, a Dobsonian Newtonian reflector is an excellent choice for someone with a car. (Except the luxurious ultraportable LiteScope which syyuen168 owns, even the portable Dobsonian (>10”) is not that portable without a car)David 寫:Yes, all scopes have pros and cons.

So the alternative is to buy a big Dob and use the existing camera with its lens for wide- field astrophotography. Maybe one can make a Barn Door mount like wtyu21 or buy a budget equatorial camera mount, namely the Travel Partner 1 from BossKwan.

既然眾多師兄/前輩認同先學習,所以小弟決定用幾個月時間跟眾師兄/前輩學習一些基本功,一邊繼續收集各器材資料,希望到時不會嫌小弟麻煩
