Menno,

I think I am going to go for this:

Menno, Ah yes, I see the IFN is much brighter up there. Maybe I'll give that a try. The trick is to find a FOV that has a filament structure with light and dark areas. If you choose a region that is just solid nebula, then you won't be able to distinguish LP from the IFN. The author of that image at...

Nick, I had version 1.8.5. I just installed 1.9.2. Now I see the Astrophotography Persona. I'll give it a try. Just looking at the panels, it looks as if it supports OSC, but I wonder about LRGB? Complicating matters, now I do W12RG instead of LRGB. However, I have plenty of old LRGB sessions that I...

Hi Nick, Affinity Photo is an incredible bargain at $25 (last I checked). So far, I've just used it for standard post-processing tasks. I need to update to the latest version that came out a few weeks ago. My version doesn't have an Astrophotography Persona, at least not to my knowledge. Thanks, Brian

Hi Menno, In this photo of M81/M82/IFN, I indicated the position of HIP 46977. Is the dense part of the IFN above the top boundary of the image? I was planning on the area within the red rectangle. A few days ago I searched the InnerWeb for discussions of the IFN, and particularly surface brightness...

Hi Tim, I have only anecdotal evidence to support the assertion that no matter the aperture, one can only expect to do no better than what the current seeing conditions allow. One exception is lunar and planetary imaging. My yearning for more aperture stems from a desire to capture more photons per ...

This came out better than expected.

Here is a good example of how atmospheric turbulence can affect LRGB astrophotography. In the first image, the atmosphere was steady from beginning to end. In the second image, the atmosphere was turbulent in the beginning, but quickly steadied. The first filter I use is Red, so it was most affected...

I was fortunate to have had two clear nights in a row, a perfect opportunity for experimentation. I have a mono camera and filters. I like the flexibility, but it also presents some challenges. My biggest challenge is my refractor. It does not focus blue very well. I've learned that conventional LRG...

Yep, just as I suspected, the culprit was one of APP's "automatic" settings. The following image consists of the same data, but processed differently. In the "Integrate" tab, APP offers two controls. The default setting is "automatic" and "quality". That setti...
