BAADER BESSEL V PHOTOMETRIC FILTER Computerized This expedient allows to balance

This expedient allows to balance the exposure of each channel with the ratio of 1:1:1

On the telescope side you can find an M48 female thread while on the camera side an M42 male thread

The ASI664MC has a HCG mode which effectively reduces readout noise at high gain settings while preserving the same wide dynamic range that you would get at low gain

BAADER BESSEL V PHOTOMETRIC FILTER Computerized This expedient allows to balanceThe Baader Bessel V filter is a precision grade photometric bandpass filter with a central wavelength window between 500 700nm. The UBVRI system was developed in the 1950s for the 0. 9m McDonald Observatory telescope and initially consisted of a Johnson UBV filter set, later extended by Cousins to include the R and I filters for the red region of the spectrum. The filters of the extended UBVRI system according to Johnson and Cousins include: U
