I've put this in this forum as a tip for newbies (and not so newbies that are a bit slow on the uptake like me
).
The importance of an IR filter when imaging with a webcam. This is probably an extreme example, but those that know reacon that you need to have one when imaging with a ToUcam and an LPI as well.
These two shots were taken with my SAC 4.2 colour planetary webcam in identical conditions and processed using identical settings. The only difference is that for the second shot I used my DSI IR filter, (for those that don't know the
history behind this revelation see this thread and
this one as well ) and adjusted the exposure and gain. No colour adjustments have been made anywhere along the processing line.
Anyway...I've ordered a new IR filter, but in the meantime it suddenly dawned on me that I already had an IR filter (of sorts) in my DSI. So I popped it into my SAC 4.2, mounted it in the ED80 and shot a couple of avies with it to see if there was much difference.
The images speak for themselves. Even an elcheapo IR filter can make a huge difference.
