This might also solve the issue of the dialogs that always pop up behind the applications since it's just one window.

Just a quick mockup of what this might look like on launch, and on connecting to devices.

I like this idea. I'd rather have the entire application combined into a single interface with tabs. On multiple monitors it can be nice separated, but honestly once I'm imaging I'm only in EKOS. I think if all the main tabs were open on launch, or at least KStars & EKOS overview. This would help solve in my mind the suggestion below that this application is actually two equally important applications, and EKOS is hidden inside of it with a tiny button. Additionally with tabs, I could also see adding the INDI control panel as one of the tabs to control parameters of the equipment not visible on the other tabs.

Speaking of interface...this is a small suggestion for the current non-tabbed system, but think it would help new users. I would potentially make the EKOS button larger or wider on the main toolbar. That tiny button mixed in with the rest of the buttons hides the importance of what's under it.

That should work for you as long as you don't run the update again. It did for me.

This appears to be an incompatibility with a recently released boot loader or eeprom for the 8gb version. Reverting back to the default 1.5.4 stellar mate os fixes the problem for the time being.

Thanks for the compliments on the website. I've seen traffic more than double every year with a steady clip of a few thousand every week now from all over the world. Just shows how many people really have a desire for Mac applications. Thanks to the INDI community there's support now for the majority of the hardware on Linux and Mac.

Regarding the filter wheel. I too would occasionally shoot all one filter each night, especially when doing narrowband. But recently I started returning to sequences that rotate the filters every hour so that I could refocus, and maintain an even number of frames per object if I got caught up with a string of bad weather. But it's those sequences that started messing up the flats, and I didn't realize it at the time until this post where I started to examine what was happening very closely. If I did a sequence of 30 2 min HA, SII, and OIII, and set it to repeat each night, after finishing OIII the filter wheel would move in reverse and stop at HA. So half my frames would have the filter wheel orientation from clockwise approach, and half from counterclockwise approach, and I was never able to fully remove the dust motes. I just thought I was doing something wrong. But now, with unidirectional movement enabled, I'm pretty confident I will be able to do sequences with no problem.

Just need to get that updated driver installed.

What's the best way to get the driver? If someone compiles it, I know how to get it into the Mac KStars client package. They would have to send it to me or attach it here. I'm happy to test if it fixed the issue.

I attempted to use the ZWO ASIIMG software to verify filter direction changes using the "One-Way" switch option for the EFW. Unfortunately ASIIMG is saving unexpected characters (quote marks) into the CFA field for CFA='NONE' and Pixinsight will not process it because it doesn't understand. I don't have the patients to erase it from all the images and try reprocessing. But I assume the One-Way switch fixes the issue and should be added to the ZWO EFW INDI driver for all their filter wheels, not just the 2" version.

As for the unidirectional move, that is indeed an issue of INDI. The ZWO SDK does support the EFW[SG]etDirection calls to enable unidirectional movement. It's just that the INDI driver doesn't use it, and/or has no setting that the user can change...

So did you use ZWOs software (ASICAP?) for this test? Does that support the unidirectinal move? Would be interesting to see Test 2 with it enabled...


I used EKOS for this, not the ASIIMG program. However, I'm in there looking at it now, and it has an option to move one way. So we must be able to turn this on in the drivers for INDI. I'm going to test it now.

I've finally conducted the testing. Conclusion is that in test 2, the filter wheel is not aligning at the same spot. I believe this is due to bi-directional movement. I did not open the filer wheel to check as I didn't want to mess up the tests. What I think is happening here is in test 2, you move forward from slot 6 to 7. But then when shooting flats, I had it move from slot 0 to 7, and I think it just does this reverse to take the shortest distance. But the sensor that detects the alignment is only reliable turning one direction all the time.

I'll be sending these findings to ZWO to see if they can force the EFW to move in only one direction. If it's possible to fix this in the driver, then we should do that for sure. I also had this issue with my ZWO 1.25 8 slot filter wheel, so I think they all work the same way and this is an issue across the board.

Test 1
Move EFW to Slot 7 OIII
Shot OIII bin 2 light no filter move
Shot OIII bin 2 flat no filter move



Test 2
Move EFW to slot 6
Shoot OIIi light filter move to slot 7
Move EFW to slot 0
Shoot OIII flat filter move to slot 7


Test 3
Move to slot 0
Shoot OIII light filter move to slot 7
Move to slot 0
Shoot OIII flat filter move to slot 7


Test 4
Move to slot 6
Shoot OIII light filter move to slot 7
Move to slot 6
Shoot OIII flat filter move to slot 7
