On Venus it can have the effect of cutting through the glare. IR pass filters can also sharpen lunar detail and enhance contrast, and it can bring out interesting details on Jove. It can also increase the contrast of Martian albedo features, one of my main interests at the moment. It's a simple matter of taking longer exposures.Īn IR pass filter can be used to cut through less than ideal seeing, which seems to be the norm here. Imaging Venus with small apertures is no different than imaging faint fuzzies with little refractors. After reading Reggie's post I took out my TV-85 and had it set up and almost ready to image when.I had to bring everything back into the house in a hurry! The recommendation for 8" and larger scopes has more to do with visual, but it's not etched in stone, as my sketch shows. I have a Wratten #47 that does a good job on Venus. I was able to observe cloud detail, as shown in the attached sketch I made. Back in 2012 I was observing during evening twilight with my old XT-6 using a Wratten #80-A and a Zhumell UHC filter stacked.
