擰開這幾件東西, 拿走那個 "Tube de prolongation" 的東西, 剩下 "Porte oculaire"

The older model do not have filter at the lower section while the newer version and those "repaired" PSTs have the lower filter.rogerx 寫:搞了一天~終於把前輩說的這個部份拆下來了
不過~如果直接鎖上右邊這個套筒~接上ToUCAM
左邊這個不裝~會因為少了左邊底部那片濾鏡
感覺ToUCAM爆亮~調到1/10000秒曝光還是太亮了
而且左邊這個套筒跟您貼的照片上不同~它的底部沒有濾鏡?
不知前輩處理時有特別要注意的地方可以建議嗎?
感謝~
The "old" PSTs have the energy rejection filter built into the objective (the red coating on the objective lens). In the newer design, the energy rejection filter is moved to behind the etalon and it appears as the "larger" filter at the lower section of the eyepiece holder. The upper smaller filter in the eyepiece holder is the blocking filter.
If you do not use the energy rejection filter, the upper blocking filter will deteriorate rapidly due to the high amount of heat.
