  1. No adaptations are needed for the Benro. The Skywatcher Star Adventurer is a lot cheaper and does a great job. It was the very first tracking mount I got about 10 years ago and I was using an EM-5 back then.  The only thing is it needs to be polar aligned first and that means you have to be down on your knees to look through the polar scope. After a while, that became something that put me off from using it. But otherwise it does a good job.

    Is it tracking in alt-az or equatorial?  If alt az you should be ok at 20 seconds.  Field rotation starts to show itself after 20 to 30 seconds. If equatorial a rough polar alignment should be good for 30 secs

    Tracks in equatorial. It doesn't need Polar alignment it does a single-star alignment at the moment but 2 star is promised. Although I always start with it pointing roughly North out of habit.

  3. Yes, the mount does do tracking. I am taking it one step at a time and will up the exposure time in stages to see where the star elongation cuts in. I have tried my 300mm lens (600mm FF equivalent) and using that I still get round stars at 10 sec. So will go to 20 secs next.  Just need clear skies as the clouds have heard I have a new toy so they come out to look😀

  4. Sold all my astro gear earlier this year and have now gone back to basics.

     

    This image of M31 was taken using my OM-1 camera with 40-150mm f/2.8 lens + MC-14 teleconverter so an effective focal length 210mm. (420mm FF equivalent). F/4.

    153  x 10-sec lights at ISO 8000. plus 10 Darks.

    Used a Benro Polaris mount on my cheapo camera tripod.

     

    Setup time 2 mins!

  5. Thanks @StevieDvd for the info.

    I do have the preferences set the same and it does check for updates on start up.

     

    The difference is my repositories are at version 1.8.9-0

    Tried adding the new version but it won't take it.

    So finally delete existing installation and do a complete fresh install.  - Success!    It downloaded 16 updates after doing the fresh install and my repositories are now at 1.8.9.1. 

    Will now have a look at the comet alignment tool.

     

    Thanks for the help.

    I think mine came up automatically a day or 2 ago, haven’t tried it yet though. Hoping to get a chance to image it (C2022 E3) over the weekend.

    Not appeared on my system. I am running the latest version (I think).

    I am on a M Mac so that might be the issue as it runs under Rosetta.

    It'll work and I've used similar but I can highly recommend both of the Nevada power supplies that FLO sells. Yes they are more money but you can kiss goodbye to any power issues in the future., plus they can be used to power other stuff too.

    Oh and the EQ6 mounts thrive on having more than 12v supplied too which was the issue I had with the brick type especially if you try to run more than just the mount.

    Just a word of caution these supplies are designed to work indoors and certainly not out in the open. So if you are using it in an observatory then fine, but even then  I would be very concerned about dew forming.  Ideally it should be in a waterproof box. 240V and water don't mix well! 

  8. The History window tab is designed to solve your problem.  Can show it by selecting it from the top menu Window - History

    If you have it open it shows a new entry after every adjustment you do.  The bottom one is the latest. To go back to the previous state simply click on the history step above.  You can go back as many steps as you want.  A lot astronomy actions do many individual steps so they add quite a few entries in the history list.

  9. I downloaded your jpg and had a quick play in PS.  (I am no expert)

    I used the Camera Raw Filter to adjust Clarity, DeHaze and the adjusted the curve settings for the darks and Shadows.

     

    Not sure its what you were hoping for but there is certainly more detail in the outer glow area now.  Would get a lot more if starting with the original files.  The data is definitely there!  If you willing to share all the source files on dropbox I would be happy to give it a go.
