here is my attempt from my balcony in Nitra. Used 8"/f5 Newton, 10mm plossl, QHY5 mono and Panasonic FZ-18. Finally I tested my little camera for planetary imaging. I also tried for LRGB composite. As luminance I used image from QHY5 and for color layer, image from Panasonic FZ-18. I simply overlayed the L and RGB image in PS with 25% opacity for color layer. I know, that it is not the best way for LRGB compozite, but I still learning about image processing and camera settings.
Anyhow, can I ask how long exposures are u usually use for Jupiter imaging? I usually set around 15-25 ms with IR filter and gain around 60-85%, when seeing is 6/10 or better (FL around 4 meters).
Hi Roman, excellent start to your Jupiter season. How high was Jupiter when you captured this? It must've been quite low?
Regarding exposure time, it really depends on your sky conditions, focal length, filter etc as you've probably worked out. Does your capture program have a histogram function?
If you use the histogram to set the exposure/gain so that the histogram is mostly full, without being overexposed, then that's about right.
Thanks! Especially from you. Jupiter was around 20 degrees above horizon.
Yes, software I use also has histogram, but I dodn't use him very often. I set exposure by eye (I set image slightly dark - underexposed to freeze the seeing distortions as much as possible by shorter exposures). Now I know it wasn't good idea, but I still reading your perfect articles about planetary imaging and trying to set my camera up for the best results.
Camera desciption tells about 15fps @ 1280x1024px resolution increasing to 60fps @ 640x480px. But now I solving problem with low fps even with 1ms exposure (problem is propably in computer). Here is a simple graph of real fps, that camera produce on my laptop. I thing, that 640x480 or 320x240px should be usable for planetary.
