Well, I want to talk a bit about AstroBin now. This picture have way more details and more of the faith nebula than the first picture. It is incredible what a longer exposure can do. Neither of which is what I would expect the true color of Orion Nebula. As long as I could hold the mount aligned.įor some strange reason, my first picture had a deep blue hue, and that is more a red. So instead of several short exposures I aimed for longer exposures. I was graced with another nice night and decided to try Orion again, but now with longer exposures and using the light pollution filter, and autoguiding. Using with a mask only on the galaxy to not bring up extra noise from the background. It brings a lot of details from very faint regions. One of the big secrets is the LocalHistogramEqualization on the galaxy. I specially liked the remove hot and dark pixels using PixelMath. And lastly this page with a tutorial and a couple of Pixinsight addons to download, which works wonders. After that I found this picture already edited with a workflow, with very interesting ideas. The begin to use HDR imaging I used the same tutorial as in the Orion Nebula post. But calibration and staking works quite wonders on Maxim DL.įor that processing I used a mix of several tutorials. So I believe i will be keeping Pixinsight for that task.
I still dont like Maxim DL to post process the pictures. So i edited it once, twice, tree times until I found a balance between showing details and not be too much aggressive. Since there is too few frames, and not enough noise-to-signal ratio, I had to make some very aggressive editing to bring up some details in the galaxy. So I will be putting both in the blog for a while.Īnyway, this was another very hard image to edit. But I used it anyway to generate a noisy picture. So about 79% of my frames I had to reject, so there was just 13 usable frames. And until I got the guiding right, there was lots of lost shots.
I spend quite a lot of timing configuring and understanding Maxim DL, so I end up not taking many pictures. But to be honest, with this level of tracking error of less than half pixel, I am excited to try much longer: 10, 20, 30 minutes exposure in the future. That changed with Maxim DL, and I was able to make a 300 seconds exposure. I could never do more than 90 to 120 seconds exposure, because my alignment and guiding was never good enough.

It didnt work out of the box, I had to read the manual and tweak the parameters, but when it worked, I was amazed. The very small less than half-pixel errors and readjustments, I think i never had such a good guiding with PHDGuiding. I was a bit disappointed.īut the disappointment vanished when I made the autoguiding work. The live view feature dont have a decent bull’s eye feature, and i could not use it to focus and to align the telescope. So this night I decided to use Maxim DL for all my acquisition needs. Very complex, very complete, but very good. So I am trying out Maxim DL and it is a amazing tool.
