I connect my mount to PHD2 using ASCOM and most nights I have the error "Star did not move enough" as well as "Suspicious blah blah, axis may not be perpendicular". This does not happen when I connect the mount via ST4 cable. I read somewhere that I can do a Calibration Sanity Check in PHD2. I am however unable to find that function in the software. Is it some pop up feature or does it have a location in the settings/brain icon? Any help will be highly appreciated.

I have recently purchased an Orion Mini guide scope and I'm keen to start autoguiding using my Altair GPCAM2 224. However, I have a MacBook and it's not playing ball. I've managed to get BETA versions of Atair Cam and PHD2 drivers on my Mac but the frame rate on Altair capture is horrendous and PHD2 doesn't recognise the camera. Therefore I'm resigned to having to shell out on a windows based laptop. I'm looking to the second hand market at the moment but all I want is the minimum specs I need to capture. I will use the Mac to process images. Altair states minimum requirements are :

Hello all Ive been through this a few times but I thought I would look at what other people think on this. Is the time spent on dithering really worth it? Or is it better to use that time to get more subs? It seems to me in my experience that im spending at least 2 minutes between shots for dithering. When I look back through my pictures when I wasn't even guiding they look much better. One thing I have changed is not using darks anymore. I used to always use them. Now I use flats and bias shots but they seem noisier than my older shots. What sort of times are others gett

Hi, I am planning on my 1st autoguiding session tonight , I wondered if anyone could help me with a few questions. My setup is 9x50 guidescope, ASI guidecam, EQ5, 130-PDS, and EOS 1000d with CC and LP Filter. I have a good view of the north, west, south, and south-southeast. 1. Polar Alignment. Should I use PolarFinder and my polar scope, or should I use Sharp-Cap to do polar alignment using the guidescope and camera?1. Considering the moon and my limited view of the west , what is a good target I can attempt an imaging run on? 2. Things I should prioritize in testin

Hi all, Im living in a fairly light polluted area, and have a Skywatcher 200p on an eq5 pro mount (which does have a synscan hand controller which has an autoguider port) and ive got a webcam which ive converted to fit in a standard eye piece. My question is, when i connect it to the finder scope what wires do i need to buy to use it for autoguiding, i figure i need a st4 to usb cable, but everywhere ive looked has said i need a GPUSB device, im planning on using PHD guider but have also heard i may need eqmod and would just like some clarification on what i actually need to purchase

I have recently acquired a heq5 pro and a 200dps newt from skywatcher. What type of mounting kit do I need to mount an orion 50mm guide scope? Or should I take the finder scope out and use that mount. Thanks

Hello Astrophotographers, Now that I have my CGEM on a permanent pier, I figured that I should get much better accuracy in guiding quality, especially at 2032mm (F10) focal length on my 8" SCT. I spent a bit of time getting guiding results that are at the very least acceptable and thought I’d share my experience with anyone who is looking for info on PHD autoguiding. In the pasten setting up for each astro session and using PHD I was generally getting RMS about 2.2-2.6ish and after stacking and processing, the soft effects were able to be negated to a great point, revealing deta

My current setup for astrophotography is an eq5 pro mount with a 200p telescope, using a canon 1000d camera, I’ve been looking at what I could upgrade to improve my astrophotos and my top priority is getting a light pollution filter and it in the middle of a city. But next I’m torn, between getting an autoguiding system and getting a new mount (heq5 or neq6 if I could find one used) I recognise I will need both eventually it’s just about which to get first. I’m that respect if I were to get the auto guider first, I would probably have to find a different way of mounting it because of the weigh

i am looking for a list of brand names of the webcams along with their model names/numbers which are compatible with PHD2 guiding software. The more latest the model, the better.

I purchased a used Logitech Webcam C160. Turns out that the chip is from the Quickcam SP4. 640x480 1/8" sensor. Would anyone here know which CMOS/CCD is it based on?

I was out imaging on Saturday night and faced an image shift problem for the first time in 3 years. Description is below: I had three targets in mind. Horse head, M51 and Pinwheel. The scope to be used was my GSO RC6, camera was my Canon 500D, mount was my HEQ5-PRO guided with PHD and finder guider. I had made sure that there was no drift when the scope pointed Southward near the Celestial Equator. I forgot to check the Eastern Horizon. I setup the exposures and after an hour found that the object had shifted Westward in the frame. No shift North or South, just Westward. Also, time a

Or, what happens when you leave your autoguiding setup unattended. The other night (28 dec, actually) I thought I try my hands at the Iris nebula (NGC 7023). Set up, aligned, etc, etc. Got guiding to work (Lin_guider on Raspberry Pi) and started a series of 20 12 minutes exposures. Sometime during the third exposure clouds rolled in and spoiled about 4 exposures. But then it cleared up again. I was quite unaware of this, sitting inside and doing other stuff (like haning out on this forum). When I got back outside after 4 hours, it had clouded over and I packed it in for the night.

Hey guys I am curious. I'm about to get myself some auto-guiding kit however I don't have a laptop to run the Backyard EOS or the auto-guiding software. I know a lot of people like to run cables to the inside of theri home and hook up tech there but where the fun in that?! Due to the freezing cold temperatures and dew this time of year, what laptops (if used outside) do you guys rock with and if you do, how do they handle with the cold temperatures. Cheers for any advice. - Tom -
Perhaps DIYers will be interested in a low cost guiding setup for EQ2 mounts. I'm not sure if this approach has been tried before, but it's relatively straightforward to implement and is certainly low cost. In early 2016 I purchased a Meade Polaris 130 scope, complete with EQ2 mount and Economy RA (clockwork) motor drive with the intention of trying out astrophotography at a low entry cost. Very quickly the prime focus problem arose - so the scope was shortened by 40mm. With this mod 30 second exposures very not too difficult, with 60 seconds sometimes successful. Of course the problem wa

I currently have a Skywatcher Star Adventurer Tracking mount. I am looking at options to improve my accurate exposure time. My first option is autoguiding. What is an effective autoguiding solution for the Star Adventurer? Or am I better off completely upgrading to a Celestron Advanced VX without an autoguiding solution?

Has anyone been successful at autoguiding a Celestron NexStar Evolution SCT? It doesn't seem to have an autoguiding connection on the mount. Some articles mention a way to do this through a PC, but fail to go into further detail. I'm aware that a wedge is needed for this, I just can't seem to find anyone that actually did autoguiding on this type of scope... -
Hi can anyone help me with some basic settings in the software for PHD2, ive used it for some time now, but I dont think my settings are right. And on top of that im still trying to get better polar alignment. Im guiding long focal length, (piggy backing my w/o zenithstar to my mak newt, to aliviate the issues on my images), ive been trying to use the drift alignment tool, but im finding that my trendlines are to erratic (another reason I feel my settings are wrong). So the mak is at the moment my guidescope which is 1000mm, and im imaging through a much shorter focal length zenithstar. M

Hi all! Yesterday evening I finally was able to have a success with my new setup. Since february / march I have been struggling with getting autoguide up and running, but due to various mishaps and lots of bad weather, I haven't been able to produce a single image, up until now. This is what came out: M13. As you can see the stars are not very clean... So guiding apparently wasn't as good as hoped for... I also used flats, but there still is a bit of a gradient, but a lot less than previous. These are 180 sec exposures at 800 ISO, so I guess I have to be at

Hi all, This is my first post (apart from the one in the welcome section). If my question is not cristal clear, please tell me and i'll turn this differently. Does anybody know about PHD 2's logic to autoguide? Indeed, considering it is often advised not to send corrections too rapidly, e.g. at the same frequency as those high fps camera, because we would end up autoguiding on seeing disturbances and not actual mount errors (e.g. low freq P.E.). So, when setting the correction interval to say, every 1s, what does happen in those autoguiding softwares? I currently foresee two cases:

Hello everybody on this community, very happy I recently joined stargazers lounge.com Last November I was able to modify my EQ5 mount via shoestring astronomy GPUSB (ST4 mount-USB laptop, my guiding camera is connected to the laptop by USB and PHD2 as guiding software) so I can autoguide it for long periods 6 minutes and more, I was really happy that this project was achieved and now I can get more details out of deep sky objects. My question is how can I go GOTO with this set up, trying to find objects to image is really time demanding without GOTO, and my goal is to take advantage

Hi everyone, I would like to use my QHY5L-II with my OAG. However, it seems like even at 2x Binning its not able to see stars. I've used Dark library, but no use even then Any help will be appreciated.

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

Hi, I am after some fairly basic advice on getting started with autoguiding. My set-up is as shown in my signature and the Atik One 6.0 with the integrated Off Axis Guider and Atik GP is a pretty new bit of kit which I have had some success with normal guiding, and I am keen to try out Autoguiding (which I have never tried before). Now, I will get onto asking for advice on using software later, but my first question is how do I set things up in terms of connecting the camera / computer / mount to one another? Atik One 6.0 Camera to the OAG Atik GP is via a MiniUSB cable, Ok with this . At- 33 replies

I had a 2nd attempt at autoguiding on m31 tonight using my synguider on my travelscope 70, with my imaging setup an HEQ5 with Equinox 80 and a modded EOS 300d. I had shutter lockup on and delay set to 3s. This is the (frustrating) result of my 15m subs... Anyone got any good ideas? All of my 10m plus subs seem to have similar Z or s shaped star trails. I know I'm doing something wrong, but not sure what... Thanks for your help, Dan
