That stack has a few images that can be weeded out using the FWHM filter. Play around with it. The less tolerance you have for subpar frames, the better your final image will be, but you’ll need to spend more time to eliminate the noise. Glad you’re using them. 1001001 likes this...
A bandpass filter is a combination of a longpass and a shortpass filter. The center wavelength of this filter is deduced as the arithmetic mean of the wavelengths measured at 50% of peak transmission and the value of FWHM is calculated as the bandwidth at 50% of peak transmission....
- Added "Calculate" check box in FocusCraft for easy enabling/disabling the HFD/FWHM calculation- Added support for PrimaLuceLab EAGLE EYE ( in Sky & T settings tab)- Added support for PrimaLuceLab EAGLE GPS (in Extra Devices) - Added remembering the selected button in Graphs between the ...
I bought the Astronomik “UHC” filter because it passes the far red/near infrared, in anticipation of eventually using it with a night vision device. It’s got high transmission for the H-β and both O-III lines, and is pretty narrow at around 25 nm FWHM. It’s a good all-around ...
Meanwhile, Raman spectroscopy, applied to 16 Ryugu particles, indicated that MOM/IOM was distributed ubiquitously throughout the matrix and revealed a slight difference between the particles in terms of their G-band FWHM and peak center positions. The G-band arises from the in-plane stretching of...

As QE max is only about 30% in this region I had to use max gain and 8-12 sec images to get sufficient stars to plate solve; There was surprisingly little sensor noise at these frequencies; A Bahtinov mask did not work in this frequency band, so I went back to FWHM ...
This post is stemming from the rising anger I've felt at posts made in this forum and in many astronomy related resources that seem to spread blatantly wrong information about astrophotography specifically to beginners. It's not 'wrong' information that bugs me, I'm well...
