  1. Hi,

    I used to have a powered USB 3.0 hub attached to the side of my mount then I would run a 10m USB 3.0 cable into my back room and connect it to my computer.  This would work but as previously stated 10m is a bit of a push.  When I first tried it I could not get it to work as I was using cheap USB 3.0 hub and cables.  I paid a lot more for the hub from 'Startech' and the USB 3.0 active cable from Lindy and I got it to work and ran it like that for a number of years.


    I am now using a RPI 4 attached to my telescope and from this I am running a Cat 6 cable into my house and computer and this works very well.  I can also use it over WiFi when not at home as the RPI 4 has its own WIFI which I connect it to.  I am running KStart and Ekos on the RPI4.

    I assume you are talking about cement, concrete = cement + aggregates like sand and stone.

    You would probably be ok normal multipurpose cement, but I would be inclined to go for sulphate resistant cement for anything that is below ground level.  I would also use a damp proof membrane between the concrete and earth to prevent it absorbing ground water.

    Thanks for the advice


  3. Hi,

    I've finally decided that I've had enough carting my astro gear in and out of the house everything I want to do some imaging/observing.  I'm also going to buy a heavier mount in the near future  so I'm not sure if I'll even be able to carry it out.

    We are going to do some work on our garden in the spring which includes having a new patio laid.  The boss has given me permission for a permanent pier as we can't fit an observatory in.  I intend making a concrete pier and have seen a number of similar projects, but I can't find out which type of concrete to use.  I've seen multi-purpose, fast set, postcrete etc.

    I've worked out that I need 8 x 20kg bags of concrete I just need to know what type.  Can anyone advise me.

    OK, with the legs collapsed the height to the tripod platform is 730mm and each leg is 900mm apart

    At full height the platform is 1220mm off the ground and the legs are 1470mm apart.

    the leg measurement is taken to the centre of the white ground pegs.


    you’ve been a great help and it will assist me in sorting out the portable observatory.

  5. Thanks,

    Can’t  have pier at this time as the boss won’t let me have a permanent set up until we move house so making portable/takedown observatory just for my scope that I can use over the winter.


  6. Hi,

    can anyone with the above mount/tripod please give me the distance between the tripod legs.

    Whilst in lockdown I want to build and portable observatory for my telescope.  At the moment I have a HEQ 5 but will hopefully be getting the EQ6-R in a few months and want to ensure it will fit in the observatory.



  7. Hi Terry,

    Thanks for the quick reply.

    I'm running it how you advised earlier this year prior to my ill health, I think I've remembered how you advised me to do it.

    I have a windows laptop so I open Ekos locally using the IP address for the RPI and connect all my equipment.  I then open another instance of Kstars/Ekos on my laptop and go into the RPI remotely.  Once this is done I set up imaging plan etc from my laptop.  I can then select the folder on my laptop where I want to save the images.  Where it says remote do I enter the folder on the PI where I also want the image to save on the PI or do I have to go back into the Pi locally and set this up.

    Just cant remember how to do it.


  8. Hi,

    I'm having a play around with my telescope and Ekos trying to remember what I used to do.

    I can set up Ekos locally and can save the images onto the SSD attached to the RPI. 

    I can also set up EKOS remotely from my laptop and save the images I take onto my laptop.

    Is there a way that I can take an image and have it save both locally on the SSD and remotely on my laptop.  There is a setting for saving images both locally/remotely on Ekos but I cant get it to work.

    When I am working locally and I set Ekos to save the images to both locations I cannot enter the location of my laptop drive.

    Can anyone help with this, I just want to save an automatic backup of my images on my laptop.




  9. Hi,

    I'm just getting back into imaging having been unable to do it for a while due to ill health.

    I'm using a Zwo 1600MM cool camera with filter wheel and 2" filters.  The filter wheel currently has the following filters in it - L, R,G,B, Ha.

    If I'm taking L, R, G, B, images is it alright to use the flat from the Luminance filter for the R,G,B images or should I take a separate flats for each specific filter.

    I'm happy that my filters are clean and as they are contained within the sealed filter wheel then my view is the Luminance flats will be alright to use for the other filters as the Luminance flat will show up any dust bunnies etc in my optical train.

    Is this alright to do as it will save some time.



  10. Hi,

    I am hoping someone can give me some recommendations.

    I'm running Astroberry/Kstars and have been using NetGPS on my  android phone to get my location .  Unfortunately I've had to swap my Android phone for an iPhone and I cannot get NetGPS.  

    Can anyone using an iPhone give any recommendations on a GPS App to use.

    May be of interest. I don't know the background for this decision. Maybe Ekos needs a profile present at first startup. But you can create a profile that is not called "simulator", and edit that. Eg, "myTestProfile". Just populate that with simulator drivers. It's also possible to mix "real" hardware drivers with simulator drivers for test purposes.


    Once I realised I could not get rid of the simulator profiles I then did as you suggested and labelled them up as 'Test' and then I could p[lay around with my equipment etc and delete at the end.

    Unfortunately I'm left with a couple of Simulator Profiles, I'll just have to live with them, a small price to pay for a great bit of software.

    The simulator profile can not be deleted in Ekos, because it is used for development purposes. "It's a feature, not a bug."


    I set up my own profile and called it Simulator and this profile can't be removed even though I set it up.

    A simple Jennov POE (3MP) is a remarkably good bit of kit for merely £35.90 (it's an Amazon "Choice"). The joy is that being POE one cable carries both power and data.  The unit itself is tiny.

    However, the issue you need to consider with any CCTV camera is data storage. It will soon fill up a hard drive if continuously recording (say) a 28 day cycle. Ideally, you need a network video recorder (about £100). 


    Ill have a look



  14. Hi,

    Thanks for the reply.

    Only reason I'm looking into it is due to the fact that I've had a coupe of near misses with my equipment  and software going mental so I thought there may be a way to keep my eye on my equipment from the warmth of my house.

    I don't know how people can set everything up, leave it then go to bed, I wouldn't sleep.

    I've seen a few Bullet type weather proof CCTV cameras that I may look into as they cost less than £30.00 and I don't need anything fancy.
