Official StarTools support forum

Hi Ivo, Thanks again for your analysis. But I have some good news in that it seems Startools isn't the problem but AstroArt stacking is. I bought Astro Pixel Processor a while ago but never got around to using it properly but it has a good reputation for its stacking abilities. After learning how to...

Actually the saved fits stack in AstroArt is 32 bit with this image, while the saved tif stack I posted previously is 16 bit. With my other cameras I believe it was 16 bit for both though they didn't cause problems with Startools. However, using the 32 bit fits file, the banding is still present tho...

Thanks for your analysis Ivo. As there is a vertical gradient on the images and the banding tends to follow a horizontal direction they could be related. AstroArt, it seems, doesn't give an option on the bit depth to save the image, it chooses a suitable bit depth to encompass all the data, and it's...

If it's any help Ivo an image of the Coma Cluster gave similar banding on Wipe while an image of M42 gave no problems after Wipe. The problem images have predominantly constant black background while M42 background is very variable due to dust present. Coma Cluster AutoDev with ROI after Wipe. The b...

Hi Burly, It's a WO FLT-98, WO Flat 68III, Gerd Neumann M48 tilt adjuster, Zwo 7 x 2" Filter wheel and Astronomik L-3, and Deep Sky RGB Filters, ASI 6200MM Pro Full Frame Camera. If I don't use the Wipe module beforehand these are the results of Autodev with ROI as before. They show the vertical gra...

Hi Ivo,
Thanks for the quick reply. The file is too large to upload to the forum so I've uploaded it to Mediafire

This is the L stack of a LRGB image. It consists of 180 lights stacked using AstroArt with a dark, flat and bias for flat dark.

Hi, I've always found the basic wipe setting fine for correcting any gradients, but since getting an ASI6200 I've often had Autodev problems with a ROI. The fully calibrated image had a slight gradient top to bottom which Wipe seemed to improve. Then using AutoDev, the initial display without a ROI ...
