  1. Cheers for that. Hopefully it fixes the bug with the DEC jumping issue! (Which mione doesn't seem to have) Do you mind confirming your MC version after upgrading yours? Mine is 02.04.03. The version on the website is 02.04. (02.04.0???) I am to scared to upgrade, incase it goes backwards in revision Cheers
  2. I will hopefully be trying out my EQ3 Pro tonight at guiding. I have previously, but in PC direct mode. Tonight, if it clears, I will be trying it with EQMOD, and the EQDIR adapter. I will report how it goes, but I am only going to be imaging at a max of 200mm FL. I honestly think the DEC guide problem lies in the amount of backlash in the mount. (besides the previous motor controller problem), but here's to hoping it all works OK. Otherwise, I will be aligning as best as I can, and only guiding in RA. Here's to hoping. Will let you know how it goes.
  3. TBH, I don't think it will be suitable for such a long focal length. You also mentioned putting it all into a backpack. Remember you will need to power it with 12VDC, so even a small 20Ah bat is going to be very heavy, with all your other equipment. What are you looking at imaging?
  4. The EQ3 Pro Synscan is very nice, and very portable. I am not familiar with the C5, what focal length, weight etc is that?
  5. That is seriously impressive, especially through a ST102 and unguided. Nice result!
  6. Use the default settings in the beginning, and work from there. With your setup, it should all work fine.
  7. What I would say is get your focus during the day, on a distant subject, and fine tune at night, on a bright subject. It beats fumbling on your first night, when all you want to do is start guiding and imaging.
  8. Hi all Anyone have a good idea of the differences between these two mounts mechanically? I have seen the CG-4 comes with a more heavy/sturdy tripod and has a different weight extension bar attachment. I also have seen mention that the CG4 has bearings on both axis, which seems the SW does aswell? Thanks Grant
  9. If you have an ASCOMM compatible mount, just connect to mount in APT, connect up you 1000d, and away you go. You don't need PHD connected for DARV.
  10. If it helps, I had a similar setup. 1000d DSLR, coma corrector, 150PDS, HEQ5, ST80 with lifecam as autoguider. Here's one of what I managed http://stargazerslounge.com/imaging-deep-sky/124780-rosette-nebula-dslr.html
  11. Yeah, I understood what you meant Peter. Just never knew the L lenses are parafocal, and haven't used mine a lot yet. (And I didn't know the difference between parafocal and parfocal) It seems a bit more difficult to find a bright enough star to focus on when @ 70mm, but I'll get it right eventually. Thanks again.
  12. Thanks John, I'll give it another go tomorrow morning, if I manage to wake up
  13. Thanks Kev, it's a nice little lens for the money. I didn't know that it was supposed to be parfocal, thanks Peter. Here's a stack of 5min shots with the 50 @ f4, much better I think.
  14. Thanks Peter, I'll give that a go. Just wondering, do you think the Canon F4 L @ 70mm would be better? Cheers
  15. Hi all Again, nothing spectacular. I had a quick go with the "nifty fifty" above Sadr. This only clears the neighbors roof at 02h45, so I only had about an hour and a half to get as much as I could before sunrise. Nifty Fifty on the 1000d, f1.8, 66 x 1min30 secs exp iso 800. I think next time will be at f4, iso 1600 and slighty longer exposures, to have better shaped stars. (Slightly cropped)
  16. The easiest way I have found, is to download a program called Polarfinder. Once you have entered your co-ordinates, just create a chart, and it shows you exactly where Polaris is at that specific time. Then just duplicate what you see on the chart, in your polarscope. HTH
  17. Hi all Just a quick one. Which free software is good for Long exposure control with a modified SPC900? Well actually a Astronomiser ASTSC3 II. Thanks Grant
  18. That is very good to hear, glad you sorted it at last. Now looking forward to seeing your guided images. Cheers
  19. I don't know of a guide, but if your dec is tight, you should tighten the central allen grub screw, not slacken it. Loosen the two outer bolts and tighten the central grub until dec is loose, but not to loose to cause backlash. HTH
  20. Good news. The star will stay centered, as it is just a simulator. But hopefully that is what you will see tonight in real mode. Good luck for tonight.
  21. Yeah, it wont calibrate on a simulated star. EQMOD and PC direct mode works fine with the cable you have, but EQDIR is better I believe. In advanced parameters (brains icon), untick force calibration, and say done. If you go back it ticks it automatically, but ignore that. Then enter cal data manually, and hit PHD. It should work. If it trys to calibrate, then it's not working for some or other reason.
  22. You could also try this to check if guide commands are being received by the mount: Connect to mount , unpark and select sidereal tracking. Connect to mount in PHD, and select Simulator as camera. In PHD tools, select Enter calibration data, and enter the data that is shown as an example. Hit begin looping exposures, and a simulated guide star will appear, select a guidestar, and hit the PHD button. PHD should then send commands to the mount as if it where guiding. It skips the calibration phase. You should be able to hear the motors recieving commands.
  23. What I do is: Setup and polar align. Switch on mount and select PC direct mode Start Stellarium scope, and connect to mount. In EQMOD, unpark scope, and select sidereal tracking. Start Stellarium, and slew to bright star close to image target. Manually align scope.Slew to target image, and take test shot to confirm.( I don't always use stellarium, and you don't have to) Close stellarium, it really slows the PC. Open PHD, connect to mount, connect to camera. Start calibration, and then hopefully it passes and begins guiding. What I would try in PHD first, is select your mount as being ascom, and not on camera. You don't use the cable from the camera to the autoguide port. This way all guide commands are sent directly to the mount. You then have good control over all parameters with EQMOD. HTH
  24. I read this on the EQMOD website when looking for a download, so no Peter.
