I hadn't noticed any specific naming difference just the wording EFW and ASI Wheel are used for the same device. FWIW I used the command line efw_initialiseefw_initialise utility from ZWO and the filter wheel responds perfectly when connected via USB.

Running as Root did not remedy the connection.

Received new device EFW
< EFW >: < CONNECTION >
< EFW >: < DRIVER_INFO >
< EFW >: < DEBUG >
< EFW >: < SIMULATION >
< EFW >: < CONFIG_PROCESS >

Ekos: "Unable to establish:\n+ ASI Wheel\nPlease ensure the device is connected and powered on."

Is it anything to do with the naming somewhere? The new device is found EFW, then it says unable to establish with ASI Wheel

I'm unable to connect to my ZWO EFW Filter Wheel via a localhost connection. All works fine with a remote connection listening to port 7624.

With the EFW Filter wheel direct USB to Laptop connection for localhost connectivity, when I run the indi_asi_wheel driver via the command line the resulting response indicates that the driver is listening on port 7624 like every other drivers does but fails to read everything from the device;

The next line should read name='ACTIVE DEVICE' I believe.

Anyone know how to remedy this?

Are you using KStars install from Ubuntu repo or from the PPA? The latter being the suggested source. If you're sing a single RPi I presume you are using a power USB hub (this can work wonders).

I use the EFW7 and an ASI120MM with my ASI1600MM-C. The EFW and ASI120MM use short USB cables, both into the ASI1600MM-C hub which in turn uses a single USB cable into my RPi3.

I'm not sure if you can use the indi_asi_wheel driver for the EFW with a simulated camera, I could be wrong.

Have you tried the EFW Initialization Tool found under the SDK Tab of the Software page. I'm not sure what it does but maybe it will help.

I presume your setup is not permanent and therefore when you setup before each session you are assembling the tripod, mount and scope. Having witnessed a CGEM being set up and used, guiding is noticeably better when time is spent on mechanical polar alignment i.e. level tripod and accurate inclination (altimuth). What KStars offers, with its Polar Alignment Assistant, is a precision RA alignment. Get that spot-on and your guiding performance will improve with less pulses and possibly little if any DEC movement. Precise polar alignment will also allow you to accurately model/expose your mechanical errors, if any. Using the Polar Alignment assistant will give you the confidence enjoyed by owners of permanently mounted rigs.

The plate solver works very well with an image containing distinctive stars. In my experience it doesn't like solving around the NCP, nor deep inside the Milky Way, nor does it like globular clusters. I tend to slew East to somewhere around 45 degrees for my first solve, then another two on the same side in a triangle from the first. Once the scopes starts to be more accurate I delete the earlier solves (the one's not centered in the plot graph) and continue with more stars until each slew is perfect.

After I've done this (which takes a handful of minutes) I will then use the Polar Alignment Assistant tool to double check my mount alignment. If it is indeed out (a major contributor to poor guiiding) I will of course manual adjust my mount using the PA Assistant (sometimes needs to be done twice) and then restart the start alignment/plate solving.

Note: If I move to other side of sky I will again solve at least another three stars, again deleting the ones that don't fall in the centre.

IMPORTANT: just in case, save the mount model as you progress.

Start to finish this is 20minutes. The most valuable 20min you'll ever spend in an all night session.

After this your guiiding can now be set up. Try it with the built in guider first and, should you prefer, PHD2 after. Both guide applications will need a few tweaks to the setup parameters (Max and Min Pulses) is where the magic happens.

Note: I frequently attend imaging evenings with a CGEM owner. He doesn't use Ekos (yet) and simply uses the hand controller to set up his two/three start alignment before using PHD2 to guide. His guiding is either great or horrid depending upon his physical polar alignment at setup. The PA Assistant is a brilliant tool and with the subsequent accuracy of polar alignment, it's your new guiding BFF.

Mount Mechanical Problems: One accurately polar aligned if you are concerned about mount error then log the Guide Data. This will produce a text file that can be exported into a spreadsheet to visualize possible mechanical errors. The guide data log gives you an insight only, you will need to use some dedicated mount software to fully evaluate mechanical errors.

Increase your guide steps in the Options link to 3000 (assuming it's less than 2000). Keep an eye on each guiding change and set the Minimum for RA and DEC above the general average. 150 might be a good start. Read mouse overs for explanation of each parameter. After that it's all about tweaking to Max and Minutes to find a balance for you setup. It can vary depending where in the sky your imaging and also how good your polar Alignment is.

What mount are you using? Does it have active encoders when manually rotated?

If you want to know where you are after a manual movement then maybe the Plate Solver can assist. Don't Sync when you capture and solve though and save the captured image with the WCS data in it.

I use EQ6 and can comfortably achieve under 0.75 arc second if its not windy using the Ekos internal guider. Depending upon where in the sky your imaging you may need to tweak the guiding settings a few times to establish a reliable performance for that position. As with all guiding, polar alignment, scope balance and bias weight is key to optimum performance.

Is their any particular reason you don't like the RAW to FITs conversion provider by Ekos? I'm pretty sure there's no loss of the linear data and the FITs file contains all the stats you need. FWIW: If you PREVIEW your images as FITs to match and meet your preferred exposure level, save it as a reference , then capture your sequence in RAW.

If you're starting a fresh session use Sync three times to get your alignment modelled and then you should be on the money to slew to subsequent targets.

Quick observation;

I noticed that in the solving window you have the Solve Action setting to Slew to Target. Can I suggest you change it to Sync.

I would also suggest deleting any solved results and leave yourself with only the best results for your main imaging camera. It may not actually have any impact but it keep everything neat and tidy.

Keith Cobby replied to the topic 'NFocus - Negative Number - Inward Focus' in the forum. 3 months ago

Is it possible to add a focuser temperature calibration/offset feature within the Indi Control Panel for Rigel nStep config. The actual temperature reading does change but only reads 2.30 (two point three) when I know ambient was around 23. Attached is the nStep manual as a reference for the ASCOM compliant utility features.

I've re-read the Indi tutorials and conceded to the fact that Indi presumes the focuser is full retracted on start up and therefore only assumes it needs to focus outward. This is of course logical and akin to parking the mount. I will park my focuser at the end of each session from now on.
