Dan Holler replied to the topic 'New open project "Ubuntu Astronomy"' in the forum. 2 weeks ago

Hello Oleg,

I should like to suggest a wish list item. Is there any way to have a package selection list for installing when using an ISO? OR, can icons be made for individual software installs from the LIve boot screen? I love being able to test and look at the software, but, do not wish to install Ubuntu (I use Linux Mint) and all of the packages.

If even a list of links for installing the packages existed on the DVD, this would be great. Maybe it does?

Thanks for all you efforts on this wonderful project.

Dan Holler replied to the topic 'qhy8l & qhy5l2 connection error' in the forum. 4 weeks ago

KStars should allow 1 QHY camera to connect and function normally. In this case, the QHY8L should connect and allow all Ekos image functions. (binning, exposure time, preview)

In order to get to that state, you must have your cameras connected and the QHY8L powered. You must NOT set the Ekos check box which automates the connection process. Start INDI, then using the INDI Control Panel, connect your drive, the QHY8L, and whatever focuser, you might have. If I recall correctly, the QHY driver already included control for QHY filter wheels. In any event, I would focus only on connecting the camera first. You will ignore the QHY5l2 for the time being.

If you connect both and then disconnect one, you are all done. Nothing will work.

Also, I was told today that QHY is working on this problem.

Best wishes,
Dan

Dan Holler replied to the topic 'How can I connect external Lin_guider?' in the forum. 4 weeks ago

Unfortunately, I have never played with Lin_guider using its remote access method. But, I would suggest you load Lin_guider, its cccd firmware for the cameras, and run the program independently of KStars, first. If it works ok, then, the problem is with KStars.

If not, you most likely have firewall, UDP setting, permissions, or port assignment issue. I have used KStars and Lin_guider separately with no problems. I would suggest separate desktops for each works very conveniently. If one of the software then crashes, its very easy to recover. i.e. KStars crash while guiding. One can simply restart KStars, connect and sync.

Best wishes,

Dan Holler replied to the topic 'qhy8l & qhy5l2 connection error' in the forum. 4 weeks ago

There is a definite problem with the QHY driver not being able to address more than 1 QHY camera using INDI. You must use separate software drivers for the 2 cameras.

This problem, most probably, could be fixed if the authors of KStars or QHY would simply create a subset listing of QHY cameras and allow the user to choose a given copy of the present QHY driver for a given KStars function. The existing driver contains code which identifies many (not all) of the camera models. This is confirmed by the fact, the various EKOS tabs have drop downs allowing the user to select a camera for a given task. The problem is, when a camera is selected for a task, an individual driver is not assigned to that specific camera.

Now, specific to your question on Lin_guider, I assume that you have attempted to connect with Lin_guider remotely using only Lin_guider and it does function correctly?
If does not, then a port, firewall, or issue with Lin_guider's remote access exists.

Best wishes,
Dan

Dan Holler created a new topic ' Anyone using Celestron Mount driver with Stellarmate?' in the forum. 1 month ago

Hello,
I have a Stellarmate and am having difficulty with the Celestron driver not wanting to connect properly. Those using a Pi3 device might also help. It seems to connect ok, but during the connection displays a message that the received firmware version is expecting 3 bytes but instead received 4 bytes.

If I align the mount, it only somewhat works. I have Celestron 11GPS with a Nexstar+ hand controller version NXS5.29.6225 MC 4.06. My fork is mounted on a wedge in an observatory, so, I must use EQ North for setup. However, the present driver always shows Tracking as Yellow and appears to never completely finish slewing.

Hibernate also does not appear to work, so, each time I repower the system, I must manually be on site to align.

Any help or settings would be greatly appreciated, especially if you are a remote access user.

Dan Holler replied to the topic 'Items from last night's INDI/Ekos/Kstars session' in the forum. 1 month ago

As I mentioned in the other post, we have operated using KStars and Lin_guider for several years. We utilize LInux Mint 18 with a Mate desktop. The observatory equipment consists of an AP1600GTO, Celestron Edge14, Apogee F8300 camera, Robofocus, Atik Filter wheel, and Orion guider. As mentioned in other posts, Orion guide cameras are manufactured by QHY for Orion. The QHY INDI drivers work fine as long as appropriate VIDPID values are respected. Control is accomplished using a Dell Desktop with Intel I-7 processor.

I have a QHY2, QHY5, QHY7, QHY8, QHY9, QHY11, and QHY5L-II series cameras. I can definitely tell you for certain, multiple QHY cameras and the QHY KStars INDI driver do not work properly and should be used with caution. My present testing involves using a QHY5 guider, QHY9C camera and a QHY5L-II all sky camera. They all are recognized by the driver, however, imaging immediately results in driver issues.

Dan Holler replied to the topic 'Items from last night's INDI/Ekos/Kstars session' in the forum. 1 month ago

I know I probably should not jump into this thread, but, it's long overdue for me to say my piece concerning QHY and Linux. For many years, QHY and I have been very close friends, and during those years, I have suggested and pushed for QHY to develop Linux drivers for the various cameras which they created. This has always met with direct opposition because QHY believes that Linux represents a small portion of the user market.

Because of this lack of support from the top, this has always been a luke warm or volunteer approach. For those wishing to use QHY cameras on Linux, I offer this direct quote: "Hi Dan,
we will update the INDI driver ASAP after finishing our current Macos support, we are working on.
Yes, there probably is issue related to run multiple cameras with the current driver/indi, so it is in my
TODO work on that.

Please note, this was developed by another programmer, so we have to rework that.
Sorry for that problems, "

So, I will say this regarding INDI with QHY cameras. Users should use multiple softwares in order to guarantee use of separate QHY drivers. For example: Run KStars with a QHY primary camera using INDI. In a totally separate desktop, run Lin_guider to control a QHY or Orion Guide camera which uses the CCCD firmware driver. You will find this separation works, although total KStars is not achieved.

INDI is a slow mechanism at best when controlling multiple simultaneous tasks. When operated on machinery with limited capacity and multiple USB devices, care should be taken to isolate critical USB pathways in order to prevent traffic collisions. And while I must admit, I have not examined the exact data buss of a Pi2 or Pi3 with regard to serial communications, I have found on the ODroid, that one of the USB serial ports is being shared with the LAN interface. Such design compromises must be considered when making wiring connections.

Dan Holler replied to the topic 'AP MACH 1 GTO...cannot guide, and where's park positions?' in the forum. 1 month ago

We are a heavy user of the AP driver, having used it, successfully, for over 3 years. We have an AP1600GTO, not a Mach 1, so perhaps, some difference could exist. I agree with Mike's comments and procedure for startup. I would add to that, AP mount firmware is rather slow to load when first powered up, so, make certain you give it a minute before attempting to connect and Cold initialize. We have found on our system, it is possible to 'rush' into operation and thus cause issues.

I would also add, TEST THE SYSTEM with a real PC connected LOCALLY before running off to remote operation with some device like a Pi3. Now, I am certain many will want to argue the merits of quality and stability of using Pi3 as a computer to control their telescope, but honestly, if one really needs to remote operation, you'll want to be there for the first tests. Just take a good PC along and test the hardware, cables, etc. with something a bit more robust.

If the driver is at fault it needs diagnosed, but, we do not see issues here.

Hello

The QHY driver appears not to recognize that QHY9 cameras exist in, both, monochrome and color. KStars reports camera as -m which I assume means the driver can not debayer color images? No setting for debayer is provided. Has anyone used a color QHY camera with KStars?

I am trying to use the Celestron GPS driver, but, KStars appears to not calculate the RA, DEC values for the position. And, the driver does not have any provision for Celestron Alt / Az mounts which are using the equatorial wedge. Any thoughts or help on a work around?

We tried a Mosaic of the moon last evening setting in all parameters per the instructions, however, each time we tried to execute the event, the telescope (Astro Physics AP1600GTO mount) would move incorrectly off the target. We did not feel Astrometry, Guiding, or Focusing options were viable or necessary, so we had them unchecked. We tried with and without Tracking option checked. Additionally, we unchecked the default job constraints for Twilight, Moon, and Altitude. We intended to take a 3x4 mosaic using an Apogee F8300 camera.
Has anyone used this feature successfully? Could you share your settings, please?
Has anyone experienced any unusual slewing to target with this feature?
Thanks in a advance,

Dan Holler replied to the topic 'Latest indi_qhy driver does not work' in the forum. 5 months ago

Here is a good example to illustrate why the various QHY cameras can not all use the same driver. Attached are two screens showing temperature variation on a QHY7 camera using the driver. Notice the times vs temperature variation relative to the set point. Quite a few degrees because the system is over reacting to the larger ccd chamber size. (Eventually, I believe this might stabilize, but who knows when?)

I also tried the Cooler On / OFF button. It appears like its working, but once the temperature got outside the set range, the driver automatically turn the cooler back on. Thus, the button is a visual indicator, but not functional. The set point temperature is controlling whether the driver allows the cooler to be on or off.

Dan Holler replied to the topic 'Latest indi_qhy driver does not work' in the forum. 5 months ago

Yes, this driver needs split for the various camera models. The QHY9 camera camber is quite small relative to many of the QHY models. On my QHY7, the driver seems ok on a preliminary indoor test. (Again, a much smaller chamber and ccd size.)

In a similar sense, not splitting the filter wheel driver to have a separate non camera specific INDI driver, results in an inability to use the filter wheel with other non QHY cameras. Additionally, one can not use the filter wheel with just a serial or usb adapted cable. It just happens I have one of the older CFW1 wheels, but, I am almost certain they are alike.

More on the erratic indi_qhy driver.

1: It appears the driver is not accepting positive or negative numbers for the temperature. Its assuming all values are negative.
2: INDI is not reporting changes in the cooling power level. It constantly reports 100% cooling.
3: A value of 10 or 15 input on the INDI Control Panel might turn off the QHY camera's fan while cooling is at 100% power.
4: A value of 20 input on the INDI Control Panel appears to restart the fan. Cooling still at 100%
5: Cooling On / OFF does not work. It reports it and changes back to Cooling On automatically.
6: Filter wheel changes on QHY7 and QHY11 cameras do not appear to be working.

Dan Holler replied to the topic 'Latest indi_qhy driver does not work' in the forum. 5 months ago

The latest driver is an improvement, but, is still has bugs and is erratic. Connection to a QHY7 camera using the INDI Control Panel for control of temperature did allow setting a temperature. Restarting KStars and connection to a QHY11 camera, however, caused maximum cooling. Using INDI Control Panel to set a temperature resulted in fan shutting off, while cooling was still at 100% power.

IMHO, AT THIS TIME, DRIVER IS DANGEROUS TO QHY11 MODEL CAMERAS.
