Hello to all MAC users and astrophotographers.
I just want to chime in with a couple of comments about using MAC based apps for image capture and session control.
1. It was previously mentioned that kstars/Ekos/Indi can do all the same control as SGP or N.I.N.A.
It is cross platform, free and open architecture. I had used some of it's features, especially plate solving and mount control. It is a highly capable suite of modules.
2. My needs are a bit simpler, so for image capture I use the free app oa Capture. It is also cross platform.
I have great success in doing captures with it. It has many interesting features, including "Autorun" which allows the user to set up and run an imaging session automatically. It also has the advantage of being able to save image in the tiff format if desired. It can control videos as well, and save them in AVI or SER formats.
3. As to the comment made, that one OP did not want to use a MAC computer at the scope, Here is what I successfully use.
- iMac in my office
- Used MAC Mini at the scope (with all these apps I need loaded, including SkySafari 5 Pro).
I live in Colorado with some pretty extreme temperature swings. I have not had any issues with the MAC Mini.
- Connect the two via 370" of Cat5e cable (no major issues, just some files transfer slow down).
I also have an Ethernet switch at the MAC Mini, a powered USB 3.0 hub mounted on the scope and all work quite well.
- Remotely control the MAC Mini using the Apple Screen Sharing feature. It works flawlessly.
4. I do image registration/stacking and some PP with Siril (free and cross platform), or some registration/stacking and PP with Lynkeos (free and MAC only), more PP with Affinity Photo, Gimp and noise cleanup or sharpening with Neat Image.
This is just one, all MAC setup, that works flawlessly. And yes, there are several MAC apps for all the astrophotography and observing needs. I only use a (groan) Windows laptop so I can use Sharpcap Pro to do polar alignment. Although kstars has a polar alignment routine, as does PHD2 for MAC, I could not get them to work properly. That could be (not sure) due to my old MAC OS of El Capitan.
Dark, clear, stable skies to all.
