So in Pixinsight I tried out using WBPP, i put my lights, darks, flats and flat darks through the script and the attach image came out with this white vignetting. I've never used WBPP before so wouldn't know the first place to look in the settings to fix this. I'm gonna hazard a guess and say it's something to do with my flats. I use a redcat and 183 mc pro astro camera.
Any help appreciated.
Startools 1.8 is currently under development, Ivo is currently working a Narrowband Accent" module for duo band users , initial image Ivo has posted certainly looks interesting https://forum.startools.org/viewtopic.php?f=4&t=2225&start=10 Ivo also working on a new deconvolution algorithm so some good things for Startools users to look forward too .
Hi SGL Hive Mind,
I’ve got a real head-scratcher of a problem, and I’m hoping someone here can help me solve it. I’ve been experimenting with seeing the effects of increasing integration time on background noise levels. My understanding is that the greater the total integration time, the smoother the background noise should appear. But I’m finding that beyond one hour of integration, my noise levels see no improvement, and even maintain the same general structure.
I flagged this in another thread but think it deserves its own thread, so I thought I’d begin anew.
I figure either my understanding of integration and noise is incorrect, or maybe I’ve messed up something in pre-processing. I’ve conducted a lot of tests with different settings, copied below, but nothing seems to make much difference. I’ve uploaded my data to GDrive, in case anyone’s feeling generous with their time, and would care to see if they get the repeated noise pattern! (Being GDrive, I think you need to be logged into a Google account to access).
My telescope is an Askar FRA400, and the camera is a 2600MC-Pro. All a series of 120-second images shot from Bortle 8 skies. For each test, I applied some basic functions in PixInsight just to get images to compare: ABE, ColorCalibration, EZ Stretch, Rescale to 1000px. I used SCNR to remove green from the first tests, but forgot that step for the second batch.
Any idea what's going on? Why isn't the noise smoothing out past the one hour mark?
Here are my PixInsight ImageIntegration settings:
Recently I bought a ZWO ASI178MM for planetary/lunar/deep-sky imaging and last weekend i had clear skies so I was able to capture videos of the moon in two panels. I have already processed the videos in AutoStakkert, I used 3x drizzle because I intend to print the image so now I have two 120MB TIFF images that i would like to combine in a two panel mosaic. I tried doing it in Hugin, a free panorama stitcher but the program crashes due to the file sizes being too large. I have searched for tutorials on using DynamicAlignment in PixInsight but it seems to me that i'll need a reference image to be able to create mosaics in PixInsight. Is there any way to go about this, I feel like this should be a pretty straightforward job but I am not very experienced in PI so I would really appreciate some advice.
I tried using DynamicAlignment as you can see in the attached screenshot but the result was just a cut version of the target image, aligned perfectly to the source image. It would be perfect if it didn't cut off the lower part of the target image.
