Whether the below really counts as EEA I am not quite sure -- but it does seem extraordinary that technology has advanced so rapidly over these past few years that it is now possible to observe four or more objects - in this case local galaxies - in really very high detail from a Bortle 7 back garde...

To the point that MarMax makes -- I have also seen something similar in the past - i.e. with needing to increase the offset of the lights when going to dark sites - or else ending up with a clipping problem during EEA.

Just to add in one observation on the livestack problem. I have also observed that - as well as with e ASI294MC camera - you also get the hot pixel problem with the ASI294MM mono camera used in either mode - 11Mb or 46 Mb.

Hi Thomas, I have currently been using the exact same camera, up to date drivers and version of Sharpcap over the past week or so. Everything has been fine except for on one night when I also had a connection/ disconnection problem. The fault turned out to be with the USB 3.0 cable connecting the sc...

That is an outstanding image Leandro and Dave - really good detail and colour contrast across the entire mosaic! Tim

Thanks Robin. I also like that option. Borodog's comment is true of e.g. PI post-processing which seems to get rid of the hot pixels - i.e. following calibration with the flat and dark, the cosmetic correction process is set to remove hot pixel outliers at various levels of significance with a slide...

Hi Robin, Thanks. Maybe it all is indeed to do with some idiosyncrasy of the chip? Just to note that the problems is only apparent while I am viewing live in EEA mode - generally I also concurrently save the stacked raw light files and then calibrate, debayer and integrate them afterwards using exac...

Just to confirm that I am using an ASI294MC camera -- re suggestion over on CN that there might be an issue around that particular sensor returning out of range values for some pixels?

Hi Robin, I was running SC 4.1 (latest version) livestacking for EEA observations of some galaxies - with the appropriate darks and flats. At the same time also dithering, guiding and saving the stacked lights for later processing. It worked well - after 60 min I had a nice image of NGC4449 up on th...

Dave, Thanks for all the processing details. If I do anything good enough in the next few weeks I'll record the same - there are just so many alternatives now. I like the whole concept of keeping a chronicle of some object or another because it is easy to lose sight of just how far and how rapidly t...
