  1. Hi Paul, 

    When I got my ZS73 with 73A flattener I emailed William Optics and they replied saying that " When you set the flattener at 11.4, you have to use the Zwo recommendation for 55mm back focus" with a link that will get you started.


    Scroll to item 4 and it shows a solution using 2 inch filter draw.

    Hope this helps.

    Thanks guys, APT plate solving has been working a treat for a while so that's why I'm annoyed and confused that it wasn't playing ball last night. I've also always managed to get pretty close to target for plate solving so I don't know why that's wasn't working either. Maybe I'm missing a new setting or something. 

    I had frustrating time last night. After months of APT platesolving working  ASTAP kept failing. Three hours later I went into the settings for Point Craft and ticked the box to use PlateSolve2 for near solving and APT solved without problem thereafter. So not sure if there's an ASTAP problem or not.

    Anyway, keep on going.

    A night and day difference, indeed.

    @SunshineYes indeed, after much reading on this forum and watching Youtube videos.

    Back on the 12th of May 2020 I took an quick snap of The Plough with my phone in my garden with a late night beer and became addicted. I've always wanted to have a shot at Astrophotography but was never really in a financial position to really do it for many years. The first lockdown urged me to have a go.

    @Jamgood Fantastic picture, lockdown did  have some positives.

    I took this shot of Andromeda in late September - my first DSO photo...

    @Jm1973 Thats a subject I will try soon, my first attempt was so bad I ditched the subs.


    Thanks to all.

  4. Hi all,

    Just thought I would share what a difference 10 months has made.

    Back in January I posted this.


    And 10 months later after swapping to mono with a cooled camera, I took this LRGB image.


    This is 5 x 120 seconds each LRGB, ASI183MM on a WO ZS73, HEQ5 belt mod, stacked in DSS and processed in Gimp and Affinity Photo. 20 darks but no other calibration frames.

    Still have much to learn.

    Lack of photos also puts me off buying anything. I mean if you can’t be bothered to take a photo or two I can’t be bothered buying. If you state photos to be posted later at least I would come back later to take a look.

    I prefer photos of the actual item being sold, and not a link to a retailers website.

    There are several members who use GIMP here and the videos on budgetastro.net by Doug you can pretty much follow using GIMP and he covers DSS.

    Checked that web address but it doesn't seem to exist, I got a holding page .

  7. Hi all,

    After a bit of advice. I am a relative newbie to astrophotography and have achieved what i think are a couple of acceptable results.

    My first DSO.


    Second galaxy pic from recently.


    These were taken using a Celestron Nexstar 102slt on a Skywatcher EQ3 Pro mount. I have the opportunity to upgrade either the mount or the telescope. I was looking at the Skywatcher ED80 or the William Optics Zenithstar 73 II APO scope wise. Was looking at the Skywatcher HEQ5 PRO mount wise. So the question is, which should I upgrade first, mount or scope? OR wait a while and save enough to upgrade both at the same time?

    Thanks in advance,
