"白光"為何綠色的? 連米粒組織都看不見，你不懂把Gamma調低些嗎?

viewtopic.php?f=15&t=849

今日留堂重做。

The reasons of bad photos are:
1. bad skills
2. bad seeing. Less than 20 frames out of about 600 frames for 85% quality. I was forced to accept bad frames, otherwise no full disc can be produced from drifting.
No time for detention class. Sorry! Will try harder later!

Green continuum was used. That's why I colored the image in green. Gamma was tunned otherwise it was just flat green due to bad seeing.

Some students and I also saw the nice promiences at the bottom of the Ha picture. Their shapes were really lovely although not very big.

我這個懶人也定期看太陽的，每次寄發Lunt給用戶時都要開箱檢查一下確保Etalon工作正常。

I was taught that don't speak for the photo, let the photo speak for itself

Yes! Sir!

no, I am just a humble student following your instructions, and now just remind what you have taught
