Interesting, I did not share this one yesterday but did try to image the moon around 310pm yesterday with the 485c because the chip was big enough to get full disc in one shot through the edl…. That cam is not sensitive to infrared so did not use a filter, ended up with a blue very low contrast fuzzy image but processed the ser anyway and then adjusted the hell out of it, obviously ir is better but it does show you can image without a filter in daylight
Nice capture. I believe there are ways to deal with the "blue haze", especially if you are working with a color camera and willing to accept a mono image. The first thing you can do is use the green channel only. You might think red would be better, and it is in the sense that it has much less contrast-reducing scattered background light, and it is less susceptible to seeing. However, given that the green channel has two subpixels for every red, I find that you often need to stack a prohibitive number of frames to get a decent mono image out of the red channel. Also, telescope optics are almost always optimized for green light. So it's a good compromise. The second thing you can do is stack to FITS format and do your pre-stretching in GIMP before exporting to a friendlier format like png or tiff. Because FITS is a 32 bit float format, if you are stacking many hundreds or a thousand (or more) frames, you actually have a lot more bit depth than you think. So if you pre-stretch the FITS before exporting to a 16bit format, you will have all the bit depth you need to process an 8 bit image downstream.
Very nice Borodog. Were any filters used?
Thank you. Yes, a UV/IR cut filter. It's impossible to get a good color balance out of the ASI183MC without it. Even with it, you cannot really boost the blue channel to where it should be; it's a few percent too low and you have to correct it in post.
I always find it cool when I see images taken around the same time from different locations…. Especially during the day, that has to be much rarer
I agree. I was really interested to see that Tom Glenn and I had posted nearly identical images from last month (coincidentally nearly identical in phase to this image as well). I pictured me and someone else both imaging the Moon separated by hundreds or thousands of miles. In the case of Tom's image it was the entire continent of North America.
