Taken with the 450D & baby Tak on the Star Adventurer. This is about 5.5 hours of 1.25 minute exposures over two nights, which is the longest I’ve ever managed to image. I just left the camera clicking until the battery ran out. Processed in Pixinsight with flats & bias but no darks. I usually find it very difficult to align the camera with the previous night’s, but this time I left the scope in the same position overnight & placed Merak in the bottom right hand corner which actually worked. :)

      M108 is a spiral galaxy 46 million light years distant in Ursa Major. It is inclined at 75 degrees from the viewers perspective, so the spiral structure is hidden from view.  Visually it appears as a relatively small object (11.1’ x 4.6’) with an apparent magnitude of 10.7. Its core is estimated to contain a supermassive black hole with an estimated mass of 24 million solar masses.  I was pleased to capture quite a bit of detail on the galaxy including the Ha emission areas. The background also contains many small, more distant, galaxies. The LRGB image below was taken with my Esprit 150 and represents 14.5 hours integration time.

      I've had a Star Adventure since October, but haven't had a chance to use it until Friday night (work and weather limitations). Also, I don't have a car at the moment, so I'm quite limited to how far I can travel on my e-bike and get to dark skies.
      Ran into a couple of issues, 1. my Nikon Z50 is limited to 30 second exposures and the wifi connection to my phone so I could use qDslrDashboard was terrible (now found out I can tether directly to the phone via USB, yey!). 2. my lens started to fog (a warmer was ordered as soon as I got home and has now arrived).
      Anyway, what I did manage to get was a nice shot of the Orion Nebula.
      Nikon Z50. 50-250mm kit lens @250mm. F6.3. 26x30s exposures. ISO640. Sky Watcher Star Adventure.
      I want to try the Horsehead or Rosette next, not sure how well the unmodded Z50 is with HA though.

      Hi All, I have a Star Adventurer but have had problems getting consistent results even when setup was as near to perfect as I can do, (this was focussed on due to this issue).
       
      It took me a while to find out that when the eyepiece is is extended for focus it is very loose, so loose the graticule moves indipendantly of Polaris / background.
       
      I have asked the supplier, "Astroshop.eu", to highlight the problem and ask for their feedback.
       
      Question to Astroshop.eu:
      I have had a constant issue with Polar Alignment. As I cannot use it so often, (visibility), it has taken me a while to identify the problem. When I adjust the polar scope focus the eyepiece is so loose that the graticule moves a lot laterally in all directions in the view. I can send a video but I think you can  understand what I am saying.
      Basically I must be getting something very wrong or there is an issue with the product. The thread is so loose it is entirely unstable.
      Please advise what we can do about this.
       
      Answer from Astroshop.eu:
      1. "I'am sorry to say, but this is very normal and does not affect the function of the star adventurer".
      2. "My collegue confirmed that this will not be a issue".
       
      I have subsequently asked the guy to ask his colleague again, but some time has gone past and I have no further reply.
       
      I think it is clear enough from the text and would really appreciate some experienced answer, any comments very welcome.
      Additionally here are the videos I have sent to show them, (hand holding the phone so a bit shaky but issue can be seen. I'd really appreciate some help before I spend too much time again tring to get it to work, for reference the eyepiece wobble is around 3.5 graticule intervals, so not small. As it's full of grease it took me a long time to see how poor quality the Polarscope build quality is.

      At last, I have 3D printed an adapter to attach an angled viewfinter to the polar telescope finder. This is for the Star Adventurer polar telescope, but I think it fit even others.
      My document of how I did it:
      http://www.astrofriend.eu/3d-printing/90degree-polarfinder-adapter/01-90degree-polarfinder-adapter.html
      It works so perfect compare to my film canister build adapter. This is my first real 3D printed product I will use so I have great times.
