<\/noscript><\/a>On this comparison the greater sharpness of the B image is obvious. This is what happens when everything goes right through all the imaging tunnel, from the sky to the camera ! The comparison with IR light at left is even more spectacular, this is a band where the resolution of a telescope is noticeably reduced in comparison with visible light. I did not even resized the image at the same scale than the R and B, the level of resolution was too low ;).<\/p>\nThe images are taken with a \u00a0250 mm telescope. This is not the higher diameter available today for an amateur. Differences of resolution would be harder to see with a bigger instrument, yet sometimes we do see it.<\/p>\n
On the other hand, smaller instruments are going to see this effect quite often.<\/p>\n
So when you do planetary imaging, do not forget to give the B filter the place it deserves. Too often we see images where the R layer is more cared than the others.<\/p>\n
