This is 17 hours of data, OSC camera, 3 minute subs. When I do integration without drizzle there is no artifact. The data is undersampled, dither is 10 pixels. In the integration tab I have it set to drizzle, droplet size 0.5 and scale 2.0.
Any suggestions. Should I be using the Bayer/Xtrans drizzle?
Not sure in this case, does this also happen when you increase the droplet size to e.g. 0.7?
I haven't tried any other size. I will try 0.7.
Hi Andrew @adstottyahoo-com,
The screenshot indicates that with the used settings too little data is receiving drizzle droplets, normally a larger droplet size will fix it quickly.
On the other hand, you seem to have more than enough data for those settings. Was every frame properly dithered?
I double checked my settings in NINA. When I set these settings into NINA is used a dither calculator; I just double checked the calculations. I have my guide camera set to 14 pixel dither which is 20 pixel dither on my 294 MC pro. It's a random dither setting and every third frame is dithered.
Would it help to post the drizzle image to the Synology server and have you take a look at it. The added noise in the image has an odd appearance as well; difficult to describe.
