While waiting for L-Pro filter to arrive, I contacted seller on Ebay from whom I purchased Rocolax UVIR-cut filter last year (it was $70!)
They promised to send me the new one (hopefully the wider one).
To strengthen my case, I put together my Hartridge spectrograph, calibrated the wavelength with energy saving bulb and processed images taken with $5 webcam in BASS software..

Instead of cutting off wavelengths above 670nm as per ad, the cutoff starts at 645nm.
I am hoping for the best outcome...

Also with the same setup I will be able to check L-Pro filter as well.
