    It's not a polar alignment problem, it's a speed control issue.

    Hi Thanks but I've not used the polar scope. As I said, it's not tracking fast enough in RA so board swap is likely to be the only option. But probably not worth messing around with. Maybe I'll get a replacement in the New Year - I'll see. Louise
  3. Thalestris24
    Ha ha - I take that as a complement! Board swap would be the only option, I think. Louise
  4. Thalestris24
    Yeah, thinking about it, it's probably to do with the servo control. I suppose I might as well trash it...

    Hi It doesn't allow control via laptop/planetarium software does lt? How do you find it? Is it quite portable i.e. easy to carry around? Thanks Louise
  6. Thalestris24
    Tempting! But knowing my luck it would be another duff one! Once bitten etc. I see you have an eq1300 gt - can I ask how you find it? I know they don't have a computer interface but maybe they are quite portable and better than a star adventurer? Do you know what the difference is between the eq1300 gt and the Bresser Exos-2 which looks like it's the same but is more expensive? Thanks Louise

    Thanks but a new one is only £199...

    Hi Steve Thanks for your response. I think there's probably not much I can do with it that I haven't previously tried. The Darkframe tuning looks quite good but it's practically the price of a new SA! Maybe I'll just get another one though I wish there was something a bit better! An EQ3 Pro is only £200 more than an SA and is perhaps a bit more versatile... Louise

    Hi all I'm impressed with the images posted here. I have an SA but it's been in dry dock for quite a while (I bought it over 2 years ago). That's because I could never get it to track correctly. I got it out last night to have another go (though I wasn't expecting it to self-repair!). I attached a canon 1100d with a 200mm Super Takumar lens via the counterbalance bar. Made sure it was balanced. Of course, I put brand new batteries in . But tracking is still way off. I can get 5s but anything longer gives streaks in RA which obviously get worse with longer exposures. I suppose it is tracking too slowly in RA with the '*' setting. I'm wondering if anyone knows about any possible adjustments I could make - either electronic or mechanical? Thanks for any replies Louise

    I've never understood exactly how a red dot finder works! (I don't have one) Louise
  11. Thalestris24
    Sorry, think I was talking tosh there! Obviously you adjust PA via the wedge. I'm getting old... Louise
  12. Thalestris24
    Hi smr You seem to have removed the end of what should be the L-shaped bracket. I think you need that to adjust the mount in DEC, which is critical to polar alignment. Having said that, and in my (limited) experience, the supplied mechanism isn't the easiest to adjust - either in DEC or in RA. Louise
  13. Thalestris24
    Hi Yeah I think the counterweight and mounting bar counts towards the payload as they're 'add-ons'. You might need more than 1 weight to balance. Louise
  14. Thalestris24
    I think you might have to counterbalance that and the max total payload is 5kg, I believe. It doesn't exactly have a heavy duty RA motor. Still, nothing ventured... Louise
  15. Thalestris24
    Worth a try, I guess!
  16. Thalestris24
    Hi Yeah, without a computer interface then you can't control the mount via computer but you can still take images via APT. In principal you could switch off your mount for a second or two in order to manual dither but I'm not sure how well that would work in practice. It's not the end of the world if you can't dither. Lots of people don't bother even though they could/should! Louise
  17. Thalestris24
    Hi I think it was improved - a bit! Trouble is cloud and other things conspire to prevent me from using it very much Louise
  18. Thalestris24
    Hi I did mine - there is info and pics here (not mine!) Louise
  19. Thalestris24
    Hi You might need to service the Crayford and try and see why it's slipping. I didn't have that problem with mine but later on I did attach a SW motorfocuser and they are very good at holding the focus and make it easy to make very small focus adjustments with changing conditions -plus you don't need to use the lock screw Louise
  20. Thalestris24
    Hi Alacant You can get a set of secondary thumbscrews from TS Sorry, don't know screw size for the focusser. Louise
  21. Thalestris24
    Hi Yeah, I think the asi also needs to be set to 8-bit for ST4 operation. You need to put your logs into PHDLab so that you can see what's going on. Louise
  22. Thalestris24
    ps be aware that if you happen to be guiding with a qhy5l-ii in ST4 mode then your guide cam must be set to 8 bit rather than 12 otherwise it won't work! Louise
  23. Thalestris24
    Hi Frank It sounds to me like PA isn't your root problem. After all, PA errors will only cause field rotation. I'd look at things like balance and flex. Not sure what guide scope and camera you're using? You maybe need to look at how your setup performs unguided whilst running the PHD2 Guiding Assistant - that can tell you a lot about where problems may lie. Perhaps you can post your PHD2 settings and PHDlog analysis? How is your PHD2 calibration? Also, when you say 'everything goes crazy' can you be more specific? Louise
  24. Thalestris24
    Same one here, I think
  25. Thalestris24
    I think this is the one I bought though I don't think it was called 'quattro' then....
