  1. Hi Derek, may I suggest some editing is required. 

    Please note:

    That although there are some spaces left for say: for Tuesday the 2nd and Wednesday the 3rd,

    that if you want to book for those nights you will not be allowed to extend your stay over the next night the 20th, if the camp numbers were to be greater than 25 pitches.

    That's some jump from the 3rd to the 20th :)  and the text following the 20th is out of context.

    Sadly I will not be there this year as Sandra is adamant that she will never camp again !!

  2. Does the Hitec Astro cable work if it is plugged into the handset controller?

    As far as I can see from some quick research here https://www.celestron.com/blogs/knowledgebase/what-are-the-aux-ports-on-my-computerized-telescope-for the only RS232 interface is in your hand controller. 

    So I guess to answer your original question the driver you need is a Celestron  handset.

    You asked your question in an EQMOD thread about Hitec Astro’s EQDIR adapter.  Now that adapter replaces the HC. Because the EQMOD software replace all the functionality of the HC and lots more besides.

    You may therefore get more details if you ask your question in a Celestron AVX  forum

  3. OK it seems the cable is being recognised and windows is using an FTDI driver. So it should work.

    The question now is what is different between this cable and the others which have worked?

    I have had a quick look at the stellarium user guide and it would appear that you tell it to use com 6,

    I do not use stellarium so that is the limit of how I can help.

    Have you had Stellarium actually controlling you scope with another cable?

    Took all day to get a new computer to talk to the control gear for the scope. Seems to be OK now. Oh the fun of imaging Eh!

    It was the same for me last month with a new 4G router except I had to drive back home to pick up a screen and keyboard before I could get the imaging rig to work :(   Still it was a nice 300 mile drive !!

    Countryfile weather forecast seemed promising for Tuesday onward albeit a little cold as the week progresses.

    Hope you all get lovely clear skies.

  5.  OK the property box is a drop down. Could you select hardware ID rather than description and take another image please. I can see from your cable image that it is an FTDI chipset. Need the hardware ID to confirm that That is what w10 recognised it as.

    Does com6  only appear after you plug the cable in? If so can you also screenshot  the driver tab as well.

    TIA

  6. Can you upload a picture of your cable please.

    Hitec Astro used to use Prolific chips and some were unsupported by W10

    So the consensus was to use the FTDI 232R chipset .   So the question is what chipset does your cable use?

    If you look in device manager at the port devices and then plug your cable in  how does it identify your cable?

    If you right click on the description and select properties  Details tab what values are listed?

    This image is for my Hitec Astro EQDIR cable.

    A little later I plugged in my FTDI cable by which time W10 had updated the status to my COM3 to PHASED OUT since 2012 but in the screen below you can see the id for the FTDI chip (COM4).   This does not need any driver loaded as it appears to be directly supported in W10.

    I have an AVX mount and a Hitech Astro cable to enable me to control my mount from the laptop using Stellarium, could someone please tell me which driver I need. Thank you in advance. Cheers 

    You need to provide more details about your hitech Astro cable.   It is a long time since I controlled my C8 using the Avx predecessor the CG5-AS-GT. My recollection is that it used an RS232 interface and Celestron had its own app to control the mount.  I also had a USB to RS232 adapter  as most computers stopped supplying a native RS232 interface.

    What OS are you running Stellarium on?

    Not to mention the strength to carry the whole setup down the garden. 

     

    You could just take the mount down as all you want to do is set the altitude so that you have a reasonable start point for drift alignment.

    I was looking at the end of my garden at the paved area and thinking how long it would take before I fell backwards into the flowerbed! There is a 4 inch high wooden separator to stop soil going onto paved area. Perfect to forget in the dark! ?

    Have a look on the net for illuminated tent pegs.  They work great on campsites to stop people walking into the scopes and they do not ruin your night vision.

  9. Hi Mark,

    I faced your problem last night when setting up my equipment at a very dark campsite in Dumfries an Galloway.  I was just setting alignment via the polar scope when the clouds rushed in :( but there were a few stars visible to the south so I had to complete the task with drift alignment using PHD2. 

    I only went for one iteration of each axis but that was good enough or 2 minute subs with less than half a pixel movement in either axis between subs.

    My advice is place your scope where you will get the images you want, learn drift alignment, as Olly Penrice would say, it is the gold standard.  

    If you set up your scope at the bottom of the garden you should be able to get your altitude setting pretty well set up as long as you make sure it is levelled first.  Move it up to your patio or location of choice, relevel, use a compass to align with north and then play with drift alignment. A nice feature of PHD 2 is that you can make some notes as you align and it will remember these for your next session. For AZ ,I record which alignment bolt to tighten depending on whether the slope is positive or negative.  For altitude adjustment I record which direction the star should move according to the sign of the drift.

    I take both a vertical and horizontal at the end, mainly because I like to rotate the mount through large angles to make sure it's settled. I usually do this with light portable mounts, not so much with my EQ6.

    Thanks.

    I will be taking my  Astrotrac & pier to Cape Verde later this month so I will try that and see what the outcome is.

    I am hoping not to have to drift align the Astrotrac as that generally takes hours :(

    An interesting article thanks.   Reference 1 also looks like a fascinating read  https://archive.org/details/AmateurAstronomersHandbook

    I was going to try Kevin Sipprell's http://www.scopefocus.info/polar-alignment to see if it works nicely with PPA. 

    Thanks Themos , have downloaded the app and will try it out in the future.  In the meantime I have found this neat ruler http://ruler.codeplex.com/releases/view/3554 Its extremely light on user documentation. Its best features are that by grabbing a corner with tool tips on, it can be changed into a rectangle with the exact width and height required and its opacity can be changed from the right click menu.

    Tried it last night but the clouds rolled in just as I was on (hopefully) my final iteration. 

    Note when viewing a star's movements, your errors have to be reversed; right means move star left and down means move star up etc. Discovered after I doubled the errors in the first iteration:hmh:

    I was using Polaris as the reference star and its position on the screen was changing by about 10 pixels/min so I will either have to speed up or use a star closer to NCP :)

    Hoi i was very happy on the 8 of may, during the first try i am was able to reache  from  13 arcmin to 0.38 how ever  i wanted to repeat the  captured images next days but  its was not possibile  to resolve via NOVA the program was trying trying etc . also uploading on nova failed even the test v.jpg etc.  I reported this to NOVA support but no feedback yet. Also local solve didn't work how to get this work i get the following errors. Please can some help me with this two issues

     

    Your sigma is very high at 70.  The log says no stars found so try reducing your sigma. I would try halving it and do a local solve.  Keep halving til it works.

    Have to checked that the image is good?
