I lost several hours imaging last week due to a dew heater not working correctly. I was wondering whether it's possible to detect the gradual fogging of the objective glass by some kind of image analysis during a EKOS capture session?
I saw that guiding could be halted above a certain HFR limit. I put the resulting CR2 images through DSS and while the quality of the images fell off rapidly the star sharpness did not. I assume then that the HFR value returned for each image won't help in this case ?
Am I missing something that could assist please?
BTW - I found the culprit. USB connector disconnected but was under the coiled cable tidy so couldn't see it. Now taped up, but I'd still be interested in any comments.
Something that counts the stars and lets you set some threshold like a percentage of the stars found in the first image?. The alignment module does something like that so maybe it could be adapted.
Yes something that counts the stars then over a set threshold (say 10% difference from first frame) alarms to the user.
This may also catch where alignment is badly drifting or some other occurrences causing a major difference between the initial image.
Maybe a feature request ...
