效果一般。
未能找到一個好的Capture program，所以未能加上Barlow影。

Good try! Better than what I've done last yr.

1. It seems that there is some atmosphric abberation. Try to use "RGB Align" in Registax to solve it.
2. The frame rate is low (10Hz). Can it be increased? Try to limit the quality.
3. What about the seeing last night? It can affect the result very much. Or the focusing is not accurate enough.

Thank a lot. I will try it again with RGB align.
It's just a try on Meade LPI, it seems that the LPI didn't match AMCAP (Free Demo version ver 9.20, most lastest one) very much. Some of the paraemeter cannot be.
If I change to hight FPS, that there is so much drop frame. So, it work perfectly at 10fps.
You know that my house's windows are very narrow that it captured through the window frame. So, maybe we try tonight.

After RGB align.....

Lewis 可試試加個2.5x或3x巴羅投影，又或者用目鏡投影都可以，影像大一點，取樣度高些，一般曝光在1/30秒以內都不會太影響影像質量的，視寧度好時，1/20秒都可以。

社長,
有沒有貨? 我只有一個5XBarlow.

沒有，但你可以先借Willis或David的試試，看哪個最好用才買，C8是拍行星月面的利器，性價比很高的

不過我不時有東西要訂，可以跟我 Group Order，省一些運費的。

好呀..... That's Great ......

我建議你先試用2.5x或3x巴羅，會是個好開始。
