BAADER BESSEL R PHOTOMETRIC FILTER Size:65x65mm It allows you to control

It allows you to control antenna position and acquisition parameters of the receiver

The biggest piece has a weigth of only 15 kg – 33 lbs

This telescope comes with ESATTO 2" robotic microfocuser

Note: in order to connect the OAG-M-Pro to your image train

Another significant advantage of very low friction is that the risks of motor slipping during GOTO operation is virtually nil

BAADER BESSEL R PHOTOMETRIC FILTER Size:65x65mm It allows you to controlThe Baader Bessel R filter is a precision grade photometric bandpass filter with a central wavelength window between 550 800nm. 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
