C14 Edge ASI + 224 + 2X Powermate + Filter IR Pass 685

Unfortunately once again it was not possible to use the G filter to have a color picture, seeing the still bad and turbulence associated with low altitude of the planet continue preventing get a good color photo. Thus only left call me again to IR filters.
Jupiter is a planet with very high speed and it is already evidenced prefeitamente with photos from 2 minutes apart. In this sequence of three photos taken with the IR 685 it was possible to capture a good number of details and the interval between shots was about 4 minutes.
I'm investing in more IR filters and today reached an IR 850nm (

As the C14 has a generous opening the use of more selective filters can bring good results without much loss of light. I also bought an open Luminance filter (

Whether or not worth it, only the future will tell with extensive testing!
