I blocked almost stray light carefully.
I suppose it owes the rear surface of collimator lens.
For h-alpha light,I use a red filter on the front of telescope lens .
I will use the block bead for strong gohst.

Re: Recent Digital SHG
When seeing is good, I want to photograph it ,because a fluctuation is reduced.
In addition, I want to wait for time because I can raise fps when the intensity of light of the sun is high.

Re: ROT2 command of IRIS
Maybe,for visual using oscillations is 20-30 per second vibration and for graphical using is 5-10 per second.
For photo it need not make vibrate so fast. Conposite procedure is useful for smoothing.

Re: ROT2 command of IRIS
The binocular device is used to facilitate optical axis adjustment.
In order to use it as a spectrohelioscope, a littrow type optical system is not appropriate.
Off-axis light causes distortion.
