  1. Hi Steve, If you platesolve the Prefix will usually be the object you've centered on i.e M42 then TS for the time and filter duration etc.

    So you end up with a name like: 

    M101_Light_Red_30_secs_2020-03-16T20-36-04_028.fits

    If you are note platesolving or want to alter the name you can just manually type in 'Moon' or whatever and the rest is still added to that

    I've not used the Script facility, but the manual says:

    Script: Specify an optional script to be executed after each capture is complete. The full path of the script must be specified and it must executable. To denote success, the script must return zero as this would allow the sequence to continue. If a non-zero value is returned by the script, the sequence is aborted.

    So you can rename, move or even process each frame after its taken, must try that out :)

     

    Good Luck

  2. If it is one of the 'old' 120 cameras they had a very non compliant usb interface.

    There is a 'compatible' driver but its a kludge. Its pretty old so I would buy a new one, I have several upto date ZWO's and they work fine on a raspberry pi, so I have no doubt it will be fine on your new computer!

    Good luck!

  3. Don't remove the circlip, that is retaining the shaft in the gearbox.

    As your motor has a gearbox you wont probably feel the initial movement and because of the gearbox it will be hard to turn manually.

    If its making a noise like it wants to move, check your wiring to the motor, each phase should measure low resistance, so about 20ohms. The wire colours are often not a good guide!

    Then check your power supply make sure it can deliver a good couple of amps otherwise the motor will just stall.

    And finally check the setting on the DRV8825 that the coils get enough current.

     

    Good luck...

  4. Hi,

    That looks really interesting, reading the release notes I guess I'll have to wait for the Linux version, but the addition of Indi drivers is very welcome!

    I use it on Astroberry for Planetary/Solar and it will be very nice to properly integrate the filters/focuser etc.

    Thanks for the heads up.

  5. Hi,

    Found this interesting article about detecting exoplanets with a small experimental satellite, if you read the linked pdf,  it's really quite close to a lot the technologies we use!

    It puts taking Darks, Flats Biases etc. into a an interesting perspective, at least they are guaranteed a clear 'night' every 90 mins, but only 30 mins long!

    I like the comment that their 85mm scope in orbit is equivalent to a 2m earth based scope, and they do it all with 50ms frames!

  6. Hi, I had a similar issue with the same arrangement, the bolt is just a standard M10 or M12, the issue I found is a standard EQ5 wont fit, I spoke with RVO but they said it only fits HEQ5, 

    So I had to take a dremel to the inside face to allow the EQ5 to fit, then you need a M12 female to M10 male thread adaptor so the tripod plate will screw into the EQ5.

    If you don't have the tripod spreader you can just use a standard M10 bolt I think. 

     

    But it can be done!

  7. Hi, All its telling you is while the field size overlay is accurate, the orientation of the overlay is an unknown guess until you plate solve. Once its solves it will orient itself properly.

    You don't need to disable WCS, just don't trust it until its solved. Some rotators can be connected to send the the info to and fro, without plate solving, but I don't suppose you are using those.
