So I ended up with a 1500x1500 pixel moon.
After exporting and then doing a little editing in Paint Shop Pro to bring the exposure up to where I wanted it, I reduced image size by 50% and then blew it back up 200% and compared to the original, and couldn't see any difference. I was also using a Tokina 500mm mirror (on my Q), which is a little soft to begin with. After cropping my moon shots I ran them through a slideshow, and I could see the moon changing shape as the slideshow progressed.
I did notice that my resolution was poor, but seeing was terrible that night. But I was only stacking 8 3000x3000 pixel images. I did independently find that I need to crop for image drift before using registax, but I didn't SEEM to run into a 6 megapixel. so what does unchecking a layer do? If I uncheck all layers I should get a blank image, but that doesn't happen, so I'm confused. What's more, unchecking a layer doesn't remove it from the stack. But I left it alone and it finished eventually.ġ) How can I selectively remove or include frames in the stack, inside of registax?Ģ) The sliders seem to make the image sharper, I guess by sharpening each layer individually? but you didn't go over using them at all.
I've played with it some more, and found it takes 100% of my CPU, and I thought it had crashed.
Stacking images, plus the amazing reach of the Q should make for some amazing images! Im personally waiting for a nice clear night to take my Q and K adapter out for some astrophotography tests. If you can post some screenshots of the issues, I may be able to take a look and trouble shoot further. TIF file and pull it back into Lightroom, and do the fine detail editing. Once I have a stacked image in Registax, I save it as a. It takes me more time to prep the images for stacking than it does to stack them. Then, I crop each image, making sure that I crop them in the same place each time, so that I dont run into image drift issues. I determine how much cropping I can do to make sure that the file size is small enough and that if Im stacking RAW, my image size is under 6 MP. So, for me, before I begin Registax, I pull each of my images into lightroom.
If you are stacking images that are 3000 x 2000, having one image in the bunch that is 3001 x 2000 will cause the software to hang. Every image must be the same size dimensionally.down to the last damn pixel. That way when I stack all of my images, that particular highlight is always within a handful of px on each image.ģ - Image size.
I solve this problem by cropping the images, and making sure that when I do, I place a particular highlight (such as a visible crater) on one of the intersection points of a thirds/grid line when I crop. In a 6 MP image (3000 x 2000) even a horizontal drift of 10% or 300px will cause the program to hang when you try to align the images. When using Registax for stacking subjects in motion across the frame (like the moon) the amount of drift of the subject from frame to frame makes a critical difference. As my computer is a bit older, users with newer computers may have better results with larger files.Ģ - Image drift. Ive stacked 8 MP JPEGs with no issues, so Im sure overall file size (including 12 bit/14 bit RAW vs 8 bit JPEG, compression, etc) also has an impact. If possible, crop your images to be 6MP or less. There are a few things that Ive discovered (some mentioned in my original post) that will send Registax into a cardiac arrest and give me all sorts of errors:ġ - File size, especially when playing with RAW files makes a difference. Ive only ever used Registax to stack still images and not video files. It seems my only output option is an AVI file?!? I'm absolutely stumped.Ĭharles.You should be able to stack jpgs of images just fine, as Ive managed to do it before with some simple 8mp images from my mom-in-laws superzoom. Half the time the buttons are grayed out for no reason, and nothing i do makes it show me align points. I'm trying to combine several individual shots of the moon made with my Q, but I can't figure this damn software out.
