Thanks for the quick reply. My Sirius Pro mount has encoders that increment the DEC and RA values when you loosen the clutches and manually move the mount. I suspect that will skew things. I agree fully with always parking the mount as long as it doesn't 'pretzel' itself like it does currently. I am not sure if I saw the Park Options you mentioned in the tabs but there were quite a few EQMOD tabs. I will power the mount up later today and see if I can find that option.

John S. created a new topic ' EQMOD - Park and Home Position setting?' in the forum. 2 months ago

I have an annoying issue (which I am almost certain is a settings problem and not a bug) with regards to the home and park positions on my Sirius Pro mount. Basically, I want the home and park positions to be with the counterweights down and the OTA pointed straight to the north. I connect to my Sirius Pro with the EQMOD adapter and drivers in Ekos. When I first start up, it seems like the mount is showing random coordinates. It could be the last object I slewed to, but I am not 100% certain there. It's probably because I don't currently park the mount before turning it off. My guess is that the mount uses it's last known coordinates as the coordinates it starts up with. Currently, if I park the mount, it ends up 'pretzeling' itself around the OTA. Fortunately it is not crashing the OTA or anything, but it's definitely doing wonky things when I park it.

My question is two fold
1 - How do I set the Home/Park position in the EQMOD options to counterweights down and OTQ pointing north?
2 - If I lose power or have to restart the mount, is there an easy way to tell the mount what it's approximate coordinates are when turning it back on so I don't have to do a bunch of work to get it back on track?

I suspect this is an easy problem to solve and I just haven't looked into the EQMOD options in Ekos enough to figure out what to set yet. Any ideas would be appreciated.

John S. replied to the topic 'QHY PoleMaster' in the forum. 2 months ago

I am seriously considering getting a QHY Polemaster, but I do not want to have to boot to windows to do the polar alignment process if I can avoid it. Are you able to polar align with the Polemaster under Ekos? If so, how are you doing it? Secondly, I think it's outstanding that it can also work as a guide camera. That makes it even more appealing. I do have a question regarding guiding with it though. I have several different OTA's. Some are wide field (120mm refractor) and some are pretty long focal length (8" RC). Do you think the Polemaster would be able to effectively guide both of these OTA's on the same mount? What is the aperture and focal length of the Polemaster? Have you used it for plate solving as well?

John S. replied to the topic 'ZWO ASI 1600MM-COOL gain settings?' in the forum. 3 months ago

I just checked under the control panel for my ZWO ASI1600 and there is no offset setting in there. The first three settings are Gain, Gamma, and Brightness Should I use 139, 50 and 21 for those three settings for the typical 'unity gain' settings for the 1600?

John S. replied to the topic 'ZWO ASI 1600MM-COOL gain settings?' in the forum. 3 months ago

Thank you for the information. It was very helpful. Is there a functional reason these values can't be changed on the fly in the imaging tab? Don't get me wrong, it's not difficult to go to the control tab when I need to make these changes and to set defaults, but I would think it would be more user friendly to be able to change this in the image capture window and for running sequences of jobs. One practical example I can think of is there might be multiple jobs you run on different objects during the course of a night and there could indeed be a situation where the gain/gamma/offset need to be changed on the fly. If you have to make the changes globally in the control tab only then you don't have an 'on the fly' method of capturing with alternate settings. Perhaps this becomes more of a wish list item at this point.

I found a gain setting under the device options, but it doesn't look like this is settable in the imaging tab in Ekos. I also did not find any settings value at all for offset. I am new to CCD's as I have been using my Canon DSLR prior to this so I am very open to the fact that I could be just missing something.

I recently purchased a ZWO ASI1600MM-COOL camera and have just now started trying to set it up with IND/Ekos. While the camera seems to connect and image just fine, I can't find any setting for adjusting the gain. Am I missing something?

John S. replied to the topic 'NGC Objects Thumbnails for object planner?' in the forum. 3 months ago

I am not sure what the deal is, but it seems the initial placement of the window is confused. I hit the move window button a few times and the window goes to where it's supposed to and then things seem to act normally. I am not sure if there is a way to force it to be docked when first opened or not, but it doesn't seem to be going that way by default.

FYI - I have completed both the NGC and IC thumbnail object pulls from the NASA SkyView site and have made them available to knro for further review and possible implementation. I have no doubt there is more work to be done there as I did not do a thorough QA on each image. Give me some slack since there wer eover 13000 of them. :)

John S. replied to the topic 'Cheap USB Webcam and platesolving' in the forum. 3 months ago

Ok. That makes sense. The interesting part is when I set the C270 to YUYV encoding instead of MJPG, it is able to do captures. I tried an experiment there and you are correct that I can not adjust the exposure length to hold the shutter open longer. It may very well be beyond the hardware capabilities of the webcams. I still get nothing woth MJPG for either capturing a still or live streaming of video though. I do notice that there are different settings available in guvcview for the cheap webcam vs the c270. The C270 allows me to put exposure into manual, and adjust it out to a longer value (but looks like might max out at 1/2 second). It also allows me to set manual gain. Perhaps the author of that program would be willing to help you understand how he got those abilities reported to him and that might give us some help. I expect the webcams probably have a max shutter time though and this might just be beyond their capabilities.

John S. replied to the topic 'Cheap USB Webcam and platesolving' in the forum. 3 months ago

@TallFurryMan, originally, I came up with the idea of throwing a cheap usb webcam onto the Celestron GT mount with 4.5" Newt I gave my brother. He doesn't know the night sky at all and my theory is that this could help him by plate solving what he was looking at. The intent was to just attach the webcam to the Newt inline and capture a picture good enough to plate solve.

So I found a couple of webcams I had lying around, a cheapy no-name one and a Logitech C270. Initially, I was unable to get either of them to capture when selected as the imager in Ekos even though both seemed to work properly under the Linux host operation system. Playing around, I noticed that the cheap webcam supported less modes than the C270. What I discovered was that if I changed the mode from MJPG on my C270 to YUYV ekos could then take a capture.

The cheapy webcam did not support YUYV and none of its other modes worked either. I concluded at that point that MJPG was broken in Ekos. I haven't had a chance to confirm since the update this morning that supposedly fixes it. I should be able to do that shortly though. Whenever the camera is in a mode Ekos has an issue with, it just 'spins' when trying to do a capture using that device and never downloads the image.

Did that answer your questions?

I have confirmed installing those three packages has changed the behavior so that what's interesting launches and opens a separate window instead of embedding itself in the kstars window. Perhaps I am missing another QT or QML package? I suggest we make whichever of those 3 packages I installed (if not all) dependencies on installing kstars so this doesn't happen to someone else.

John S. replied to the topic 'NGC Objects Thumbnails for object planner?' in the forum. 3 months ago

I think I have the what's interesting problem at least partially solved. Apparently, Linux Mint does not install the the QT packages by default.

sudo apt-get qtcreator qtdelarative5-dev g++

This got things going, but it does pop up a separate window when launching. I am able to make the window go away by clicking the window box next to the X for the tool. Not sure what could be going goofy there. We may want to continue that discussion in a separate topic.

I found a wiview.qml file out there listed as part of kstars source. I downloaded it and temporarily replaced it with the different version one. It did not make a difference in behavior. I still get a blank popup window and half of the kstars window goes blank. Are there any package or library dependencies that I could be missing here?
