    You couldn't have uploaded at a better time! Waiting on my ASI Air Pro and 120mm to arrive. It's going to compliment my Star Adventurer Pro, Redcat 51 and Canon T3i. I opted for the WO guidescope which is the same price as the ZWO, but I thought the WO just looked nicer. Can't wait for it all to arrive!

    Got the sky guider pro a few weeks ago and the sv bony UHC eos clip filter. Both work great and I made the decision for the tracker based on your videos as well as Trevor’s from astrobackyard. For months i couldn’t decide so thank you for helping me with that.

    I'm having trouble getting through the video. Your voice makes me want to fall asleep. Just kidding. I picked up a svbony 32mm f4, and a usb camera module. Now I need to print out a holder for the camera. I haven't settled on the tracker quite yet. Was planning on using the svbony for polar alignment to start with.

    The PHD recalibration is needed whenever you use ST4 cable instead of letting PHD itself to fully control the mount. It is because ST4 doesn't allow the application to know where you are moving between targets. In other case you don't have to recalibrate.

    For folks that want to use the software on a Windows system on an Android emulator, ASI recommends using the free Bluestacks software. I've played around but not got everything running yet but it lets you run the app on a laptop which is nice.

    Nice. I have the Star Adventurer and got the SkyWatcher EvoGuide 50ED. I would love to get into autoguiding. I've looked up this setup online and it seems i only need a guide camera and software to run it. The general consensus seems to be around the ZWO ASI 120mini mono camera, and PHD2. Is there anything else i would need, or can i just take it from there?

    @vladimirbotko9576 3 года назад

    I can imagine my first auto-guiding will lead to 3:1 time spent on set up rather than taking pictures :) If I may perhaps stupid question, at what point shall I start tracking with SkyGuider, as the mount does not have go-to system, once I found the target and centered it? and then? never switch it off right? Because without goto I am mostly afraid of loosing faint target..

      By itself, the Skywatcher uses 'open loop' control -- it uses its internal clock to turn the telescope and camera. This contraption adds 'closed loop' control -- the Zwo's camera is used to repeatedly take pictures and they are compared to provide continuous feedback to the Skywatcher to make corrections if there are any discrepancies.

    • @geonerd
      @geonerd 3 года назад

      Have you tried drift alignment? Bolt on your longest lens and run a few iterations of this: astropixels.com/main/polaralignment.html It's a bit tedious, but it does work very well. I can get 5 min at 300mm on my Fornax fairly easily. And If I really nail it, 8~10 min is not out of the question. (Getting it that close usually takes more time and effort than it's worth.)

      We need to consider the context, right. Peter's rig is a portable one that he can easily chuck in a car or in a trekking backpack. As much as we'd love to have pin-sharp tracking on the field, we (or almost everyone, really) can't really schlep up a mountain or down a dark trail the fancier, more accurate trackers due to their size and weight. ¯\_(ツ)_/¯

  • @Ambress
    @Ambress 3 года назад +1

    Funny a little perhaps, but I've never used the nosepiece for my ASI120MM-S with the ZWO Mini Guide Scope, because it will screw directly onto the scope's threads after removing the wide angle lens. The nose didn't seem to fit, so I thought was was doing the right thing, but being more persistent with the nose today, it does in fact slip into the guide scope if you wiggle it a bit to work it past the tension bands. Then, focusing is achieved strictly using the fine focusing tube of the scope, not requiring much effort to focus. The scope was on a ball mount so I could position it to point wherever I found best, but sometimes the cable ports weren't positioned as I preferred and I was just wishing I could rotate the camera body a little. Well, nose to the rescue, now I can and there's no concern regarding focus because I can fully nest the nose to bring the camera flush to the back of the scope, set focus again using the fine focus adjustment, then leave it set for all use thereafter.

    A bit confused here. When you talk about the workflow at the 22.22 mark you say after step 5 is when you turn on guiding. Don't you mean Tracking!? You need to start the mount to track first, then you can turn on Guiding in PHD2 right? YES? NO?

    @leonidtalas696 2 года назад

    Question.
    If iOptron Skyguider only has RA motor, this means we can only control RA axis. Does this mean that all the autoguider is doing is minimising the internal gear mesh error in the Autoguider RA assembly? And that only makes sense when precisely polar alligned?

    Insanely helpful and very greatly appreciated. Kudos to you Sir. My guidescope and cam are in DHL-ing their way to me and thanks to this tutorial I anticipate hitting the ground running with them.

    Excellent video however I've run into a still unsolved issue that others may have encountered. After following each step of the tutorial all appears fine. The issue I have is that once I connect my ZWO ASI 294MC Pro camera through my normal procedure (simply plugging in cables) PHD2 indicates that I'm using "another camera" and the Advanced Settings/Camera Properties panel defaults to the pixel size (4.63) of the main camera and not the 3.75 that it should be for the guide camera. All gear being used is the same as shown in the video. I'm pretty well stumped at this point. Any attempts at calibration result in failure.
