About this product

Model:  ast_psh_t_gsodlx
Part Number:  PSH-T-GSODLX

The manual Dobsonian mount offers simplicity and ease of use but one of its main drawbacks for inexperienced observers is the need to manually search for galaxies and nebulae. "Star Hopping" can be difficult for users who do not have a very good knowledge of the night sky and that is why they often gravitate to "Go To" mounts.

This Push-To  system made by Asterion provides both experienced and beginner observers with a useful and modern solution. The system consists of two encoders with a controller and brackets suitable for set-up on a GSO Deluxe Dobsonian (StellaLyra)

The vertical axis encoder is set permanently and the horizontal axis encoder has a quickly removable fastening which allows prompt disassembling of the telescope for transportation. The Push-To setup can be performed in several easy steps:
  • Install the encoders on to the telescope mount 
  • Install compatible planetarium software on your computer or for mobile devices use the SkySafari or StarSeek application 
  • Plug the power supply in to the controller and connect your device via Wi-Fi 
  • Perform a routine multi star alignment

 

This system will work wirelessly with Sky Safari or Orion Star Seek on Android or iOS, these apps are available for download on Google Play or App Store.

Specifications:

  • Compatible telescopes: GSO Deluxe Dobsonians including StellaLyra 8" to 16"
  • Encoder Resolution: 4000
  • Connection: Wi-Fi
  • Compatible software: for PCs, any planetarium with encoder support, Sky Safari, StarSeek for mobile devices (Android or iOS)
  • Power: 12V 2.1x5.5mm
  • Package Dimensions: 16x16x16cm
  • Weight: 0.8kg

Easy to fit goto mod
Sunday, 6 March 2022  | 

Completely agree with Christopher. Minor but understandable design issues on an otherwise solid go-to kit
Easy enough to install. It felt so wrong to screw holes into my brand new (and first ever) dob mount that was only 2 days into its warranty - not any more it isn’t! It is a mod kit after all! Including something to secure the cable a bit more firmly to the mount would have been a nice touch I guess, but there isn’t that much slack and on the black StellaLyra mount it looks so much in keeping as to feel like it's part of the original mount. On the down side, if anything went wrong you would have to uninstall the whole thing to return it as no connector on the wire between the two sensors. The fixation of the Azimuth sensor is simple enough but it forces you to fix the Az tension on installation, and I wonder how long the sensor will stand up to what I set it at. I would have liked to seen a a sleeve or spacer to prevent play at the fixation end so just make sure the Azimuth sensor is at 90 degrees and flat to the base before screwing it in.
The removal system on the Alt sensor for separating the OTA is pretty quick, but be careful as the sensor will fall or bang around the stand during transport or fall on the floor unless you secure it back and as that means putting stress on the frame as only one part of the securing mechanism is in place (the other being on the clutch mount on the OTA) I opt for finding a soft protective bag to put it in instead.
Do bear in mind a good 12v power supply is needed to run this and no cable is supplied. I guess at a push you could use the battery pack for the lens cooler if your scope comes with one. Once your original alignment is registered it is easy to slew to the rough area of the next star on the screen and put the next alignment in. On Sky safari best make sure the rings for scope position are turned on. Accuracy varies depending on your alignment in the eyepiece obviously, however it puts you within the general area
You can use the free software as per their supplied links, but probably best to get at least the plus version of Sky safari, which I had from my last scope anyhow and is discounted on occasion. The downside of relying on a free (or any) app is that OS updates can eventually force you to need new hardware or software as your app no longer runs etc. My policy is to keep an old phone or tablet specifically for the scope and not update it to the next OS.
Sky Safari writers have obviously thought of the use of an EQ tracking platform in their setup which Asterion make as well, but you need to make sure that's switched on before connecting to the app, and I would imagine a reset of the platform would mean a realignment every hour. Using the both together would essentially convert your scope into the equivalent of a Skywatcher GOTO with tracking but no motors which to my mind is the best of both worlds but each to their own.
I do agree the loss of one Alt clutch is not acceptable and I'm going to try Christopher's "drill out" of the original clutch tensioner. Would be nice if he happens to have some pics of his mod, so if the person who moderates this at FLO happens to get a message back to him to supply some perhaps via SLG (hint hint) that would be great assuming GDPR isn't broken by doing so.

Excellent…. but

I love this push-to kit, which I have fitted to my recently purchased FLO StellaLyra 8” Dob. Installation was easy and connection to Sky Safari 6 Plus was very straightforward.

Basically the system works extremely well. In the encoder instructions, it told me to set the azimuth axis at +4000 steps per revolution and the altitude axis at -4000. However, in actuality, I had to reverse these (ie: -4000 Az and +4000 Alt) owing to the telescope’s movement on my iPhone’s screen being the opposite to that intended. It’s dead simple to do this in the SkySafari app.

One has to align on 2 stars first. For example, view Vega through the scope, touch Vega on the iPhone App and then touch the “Align” button on the app. Do the same for a second star, as far from the first as practicable (for accuracy) and you’re away. The App allows one to align on up to 10 stars, for increased accuracy, which means one doesn’t need to level the Dob base. If you make a mistake simply start again by touching “Realign”.

The connection between the scope encoders and one’s iPhone is a localised WiFi called “DobsonDream”. I had no issues connecting. It’s a really slick system.

My one negative is not the system, but the mechanics. In order to fit the altitude encoder, one needs to permanently remove one of the altitude clutches. Ergo, the scope altitude tension relies then on just the remaining clutch. I found this not to be satisfactory.

Even with the remaining clutch screwed up tightly, the movement wasn’t smooth in altitude. (The azimuth tension only involves replacing the existing tension bolt with a modified version on the encoder. No problems). Less tension on the clutch and the movement was sloppy.

So, my solution (if you have a technical bent) was to drill out the centre of the clutch tensioner I had removed so that the encoder axis could still be attached after the clutch and it’s thrust bearing had been replaced.

The supplied knurled M4 screw, to lock the encoder axis, now fouled on the clutch housing as the screw is quite short. So, I simply removed this grub screw and replaced it with a longer M4 screw. For a “knurled” head, which facilitates tightening, I put on 2xM4 nuts, tightened against the screw head and put heat shrink over the lot. Works perfectly and I can now tighten both clutches.

Overall, an amazing system. 5 stars for the actual functionality and 3 stars for the clutch mechanics. However, after my clutch mod, the whole system works beautifully.
