The Dawes' Limit is a visual perception measure of fidelity and in order to re-produce that visual accuracy you need to sample at 2 to 3 times the Dawes' Limit, or in this case around 0.59 arc seconds is the point of diminishing returns or over sampling. This is a common misconception.

Thank you for commenting. I had looked around and couldn't find a clear explanation of this in regards to imaging. Sounds like I'll need to spend more time in bin1.. if I can get a better mount :)

Nice James.! That's some pretty technical information, but it makes sense as to why you imaged how you did. Glad you are having some clear nights for these projects!

Thanks Isaac! We've had a good run this summer. I'm sitting on a pile of data that still needs processing.

Love this image of the Cave nebula - colour palette is superb. And thanks for mentioning how to change the Yes/No option as it was driving me nuts clicking what i thought was Yes only to find it was actually No. Why on earth did they switch it around!?? ( me thinks the person also manages a supermarket where they like to change all the isles just to make grocery shopping more excruciatingly slow 😂)

Thanks Logan! I have no idea why they switched. I have a feeling it was a personal preference by the developer. I had logged on to the pixinsight forum to compla... to voice my preference and found multiple threads on the topic 🤣 They had added the option to customize that after the.. um feedback 🙂

Hey James - This was an interesting walkthrough and also felt like a good use of the bin 2 mode here, made sense to me. I need to look at those new tools you mentioned, Ive seen them but haven't given much time yet to them. I also get halos on my cheapo Optolong 7nm but bit surprised your getting these on the Astrodon filters. I really do feel filters can be a lottery as Logan has the same 7nm as me with much better results. I enjoyed the overall balance in your final image, its a very moody, mysterious subject. Cheers Ollie.

Thanks Ollie! Filters are a lottery for sure. Its a little odd to me that the performance can be so inconsistent.
