I think this was around 30 exposures stacked. Exposures were 50 seconds at 1600 iso. Processed using PixInsight. The telescope was a cheaper Orion refractor which is why you see the blue stars. I want to try this one again. It’s just above the tree line at 5am at my house. It should be at a good position around December.
So many questions. Guided as well? Also, is this image cropped? Just curious as I see that your telescope has a focal length of 600mm. On my to do list is image what you have posted with my 600mm so I am interested in how you done this. Gary
This image is only cropped enough to get rid of overlapping edges during stacking, so not much. Yes, I used guiding. I use it on all my AP photos. Makes a big difference. I used an Orion Atlas EQ-G mount and a 50mm guide scope with a ZWO ASI120mm guide camera. I have some more pics. I’ll post another in a few minutes.
Unfortunately, my telescopes do not have the focal length for planetary imaging. You really need around 2000mm for planetary. My longest scope is an Orion 10” Astrograph. It’s focal length is 1000mm. When you get to the longer focal lengths, it becomes unsuitable for AP. You want fast glass. Probably f/6 or lower. That, of course, does not provide the narrow FOV needed to get Saturn. So, it’s a trade-off. You eithe have a long focal length for planets, or shorter focal length for everything else.
No prob! Happy to help! I don’t know everything, but I’ve got a few years of experience. Not all my choices have been good, and I have learned the hard way.
