  1. I have recently bought a Orion Starshoot Autoguider. I downloaded phd 2, eqmod and ascom stuff. After a small research I found out my mount (exos 2 gt) doesn't support computer acces without firmware upgrade and fancy cables but I have the st4 port so it shouldn't be a problem. In phd I choose camera as Starshoot Autoguider and mount On-Camera. Aux mount and AO are both none. My wiring is one cable to pc from camera and another to st4 port from camera. When I started looping I selected the star with no problem. I choosed the one star alignment option from my hand controller and after centering the Archturus in the middle of view I pressed ok and it was successfull. I started guiding and after a while I get the error: RA calibration failed star didn't move enough.
  2. Just wondering if anyone out there has any experience with one of these... https://www.firstlightoptics.com/guide-cameras/skywatcher-synguider-autoguider.html or the Celestron version (believe they're the same) and might share them below please. Muchly appreciated Pete
  3. After a 2 month wait, we finally got some clear slies last night so I had a chance to finally try out the Orion Starshoot autoguider. Sadly, I spent a long and very frustrating night just trying to get the darn thing to guide properly, but wihout success. I was getting great tracking results from my HEQ5pro mount on its own, round stars on any exposures up to about 30 seconds, but as soon as I engaged the tracking scope, it was driving it all over the place (see attached pics). I'm using the 50mm guidescope that comes in the "Orion Magnificent Mini" kit, and I made sure to enter the correct focal length (which I believe is 162mm) into the PHD2 software (not 50mm as I've read others have accidentally done ). There was zero wind last night, so I can't really blame that. Everything seemed to be done-up tight, although I have just started using the HEQ5pro extension tube to avoid tripod leg collisions, which together with the Explore Scientific AR152 refractor scope, does make for a very tall setup, but I think I can discount that because it still tracks really well without the autoguider engaged. A lot of the PHD2 tools and controls are a bit of an alien language to me, but I spent most of the night trying various settings and running some of the built in tools and following the reccomendataion, but to no avail, not even a slight improvement. Does anyone have any ideas how to get this autoguider to work? Would really apprciate any pointers - ideally without abbreviations, as they'll just make my brain hurt even more that it already does Much thanks in advance.

  5. Greetings everyone. I recently scored a great deal on facebook marketplace and bought Skywatcher Skymax 180 mm Maksutov-Cassegrain Telescope (f/15) with EQ6R-pro mount. I understand that long focal length telescopes are more suitable for planetary imaging. However, as I am tight on budget, I would like to use the same scope for deep-sky astrophotography. I have Canon Rebel T5 DSLR camera that I am using for taking images. Without autoguiding and a decent polar alignment, I can get ~30 seconds long shots without any star trailing, but that's not sufficient for imaging objects like M51. I would like to be able to integrate longer, say few minutes, thus would like to purchase an autoguider. Here are some specific questions I have. 1). The telescope comes with an 8 x 50 straight-through finder. If I were to use it as a guidescope, what type of image integration time can I expect? Has anyone done autoguiding for f/15 scope with an 8x50 or other finderscopes? 2). If the integration time will be an issue with the 8x50 finder scope, I am open to purchasing an off-axis-guider. However, considering the narrow field-of-view of Mak-180 telescope, I am concerned about not having enough photons from guidestar for autoguiding. For instance, with my DSLR camera, I need to integrate 20-30 seconds to see the nearby stars in M51. What type of OAG and camera would I need to autoguide with my scope? Are there affordable cameras (~$200) that would do the job for me? Would ASI120MM Mini Monochrome (~$150) do the job? What about OAG? I plan to use phd2 software for autoguiding rather than relying on the build-in guide port on the mount. Instead of integrating for hours, I am planning to do DSS stacking of few mintues long multiple shots, hopefully this will put less strict requirements on the autoguider. In case this information is relevant: with my current setup, I have no issue pointing my scope to a desired deep-sky object, track the object within the field-of-view of my DSLR camera for hours using the mechnical tracking of the EQ6 mount. For instance following is a single raw image of Ring nebula taken with 30 seconds shot. But it is not enough for generating high-quality images. Thank you in advance for your help. Regards, Jay

  7. Hello all This is my first post and my name is Gerry I am not a complete newbie as I have done a lot of research on this and have had some experience in the past. I'm English but live in Italy. I hope we can have some really good discussions. This is what I want to achieve I am interested in astrophotography for deep space. In fact I have a passion for it. I have done loads of research but I would like to ask some of the pros out there some questions that I don't seem to be finding the answers. Here it goes I seem to have come to the conclusion that I need a apochromatic telescope with a field flattener but I have noticed that they are not cheap! Is there a another way I can do it cheaper and still get the same results? I know everybody says that the Mount is paramount and 70% of your budget should be spent on it but if I am able for example to have an EQ 3–2 Mount with a auto guide on it will that not do the same as a more expensive mount? I notice for this man now you can buy a new motor and with a ST4 slot where you can add a separate Autoguider. Has anyone got experience with these? For example http://www.opticalvision.co.uk/astronomical_accessories-motor_drives_and_goto_upgrades/enhanced-dual-axis-motor-drive-for-eq3-2-mount.html Last question. I have seen CCD autoguider that also double up as a camera for deep space. Has anyone had any experience with these as I do not have a dslr so I can start this route if it's viable. Yes I know it's a lot of questions but until I get this straight I can't make the right purchase. Any suggestions that you would have I would be very grateful to hear them. Many thanks in advance Gerry
  8. Hello All Im using a eq6 and I'm having all sorts of problems with my guiding. I used to be without guider to get 2 minutes easily but now I'm struggling to get good shots whatever I choose. So first of all EQMOD what do people use for the RA settings for the autoguider in EQMOD? I have fiddled about with every one of them but no real improvement. What do others use? In PHD2 I have done the settings for my guide camera which is a asi120mm and the focal length of the scope is done along with the sensor size. On the PHD I've moved just about everything and nothing seems to work well enough. Can anyone give me their basic settings to see if that helps. The only thing I've changed is my way to do polar alignment I'm now using the EQMOD polar align process which might have affected it but I'm still getting objects on my gotos so I was wondering if cone error would do it also? Is drift alignment essential? I don't think so. I did do it on the south meridian as I've got views that way but not so much on the north. Help! Please guys and girls I wasted a whole session just fiddling and ended up with 8 exposures of M20 which you can see below.
