What is the ISO, seeing & transparency? 1/20 s is quite slow for this focal length... Keep on trying!

Lewis 加油！

記得當年第一張月亮照片是在老師家中拍的，用76/910折射配單反拍，之後他示範把底片沖出來，第二天老師在自家暗房晒了張照片給我們。當年的夢想是在家中設個暗房....

單張的月球拍數張是否也可以堆疊?

[Lewis]

應該可以,但只是影了五張.
只有這兩張比較少雲.
所以只做了Photoshop的加工.

我們的黑房已經搬入了電腦內.

I also think that 1/20s is way too long for a good photo. I usually try to use something shorter than about 1/100s.

It can see that the image is a little over, so next time is better.

Also, 人眼對焦 is highly inaccurate. I don't even trust my judgement when looking at liveview magnified at 10x.

I usually take many photos, with each taken after turning the focusing knob a little bit. Then a few photos should be in very good focus. This doesn't take long to do but will guarantee good result.

Of course, this doesn't work for deep sky....

其實若拍攝時能量化調焦位置便可以，Lewis 可以考慮造一個這樣的調焦刻度盤(留意Equinox 80慢速調焦鈕那個)：

這個用紙造的也可以，貼在Maksutov上便可以，每個刻度拍一張，選出最清晰那調焦位置，然後再拍多張，便有機會從視寧度的或然率下拍到一些理想照片。
