Cheapest GoTo option for 127 Mak

Recommended Posts

Hello there, I'm looking for options for a budget GoTo mount for my 127 Mak. I'm still relatively new to Astro photography so I'm not expecting amazing images. I'd hoped to be further along the astronomy road, although due to an imminent wedding and being flat out at work I just haven't had the time. Last night though me and my oldest daughter went onto the roof for a look at the moon and got a couple of nice shots. So the bug has bitten again.

Opinions on an Celestron 60 LCM  (With the Mak fitted)  http://www.365astronomy.com/celestron-60-lcm-computerised-refractor-telescope-p-2304.html

Or is something like the Skywatcher AZ much better?  http://www.firstlightoptics.com/skywatcher-mounts/skywatcher-az-goto-mount.html

I know for the long term I should be buying EQ5 pro or better, but this ain't happening soon. The 60 LCM I know is cheap as chips, my idea is when I upgrade then the kids will always get use out of it but should I bother at all?

Is there any reason why I can't mount the DSLR to the LCM and lastly, long exposure is a no no, or just not ideal? 

Best regards

PS: Been looking at the Skywatcher allview also

I dont think the 60 LCM would take the weight of the MAK, the AZ mount would be better.

If you are looking at upgrading at a later date to an EQ then have you thought about buying a second hand AZ mount? Keep an eye out on ebay or Astrobuysell as they pop up every now and again.

I agree.  I think the 60LCM mount would perform very poorly with the 127 Mak on top.

If you want something suitable for long exposure imaging with a camera and lens then I'd be tempted to look at an EQ3-2 with the dual axis motors.  I managed up to four minutes on mine with a 200mm lens.

Cheers guys for the replies, yeah, I think your spot on!

Found this via google 

"The Celestron LCM AZ GOTO mount is rated by Celestron for loads up to 5 pounds (2.3kg) while the SkyWatcher SynScan AZ GOTO mount is rated for loads up to 8 pounds (3.6 kg)"

I'm not sure of the weight of the 127 Mak but I think it would be too tight for the LCM mount, pitty as I'm on Amazon prime and I see it there for £159 lol, could have had it for the weekend. The AZ Goto is looking more likely. I will always keep it I think and then when the time comes treat myself to a EQ5 or better. I'd love to have got away for £160 but looks like I'll have to spend a few shackles more.

From memory, the 127 Mak is about 4.5kg, but I'm prepared to be wrong there.  Then you have the finder, diagonal, eyepiece, dew shield etc.

Sorry I did'nt see your replies, plus I'm not thinking right. I've the telrad finder mounted and then if I mount the DSLR etc then yeah, I'll have to rule it out

EQ3-2 with the dual axis motors.

Just to quickly jump in on this one, do you have a link to hand for the type of dual axis motors that would be compatable with this mount?

Is long exposure a no-no, you ask. A Mak is totally unsuitable for DS imaging, especially with a DSLR, because the focal ratio is far too slow. Until you start doing deep sky AP it can be very hard to believe that F ratio can be so important. But it is. Also, all this talk about weight and mounts is only half the story. Sure, you have to respect a mount's payload - but you also have to accept that the longer the focal length the more accuracy you need. The long focal length of the Mak requires very accurate tracking, certainly equatorial, for DS.

Fast frame (video mode) is another matter.

Olly's not wrong, but if you pick your targets carefully there are some viable DSOs for imaging with the Mak.  Mostly the brighter planetary nebulae and clusters.  You'd probably run out of targets potential reasonably quickly.  If you only want wide field DSO imaging then the Mak is the wrong scope, but combined with a DSLR, a decent lens and an EQ mount you get a lot of options.

If my understanding of the OP is correct, I think he already has a MAK but without Goto.

"Seen them go for a lot less on ebay"

The one in question on ASBS is mine, and was priced at that simply as one on ebay sold for £186 +£14pp 5 minutes before I advertised mine, and I had no other pricing reference.

The az goto mount handles the 127 mak absolutely fine, and I use that set up with a neximage 5.

Oops, I do apologize.  :embarrassed: 

The one you mentioned that went for £186 was probably the one I was thinking, I must have miss read it on my phone and thought it went for £86.

So, I will apologize again and go and sit in the corner and be quiet.

sorry hobsey - that wasn't meant to come across as a telling off!

Was just clarifying the pricing of it.

Dont worry, I didnt take it as a telling off.

I just felt bad about getting my facts wrong.

It is indeed.  Until four months ago all my imaging was done using just such a mount, with a few modifications.  Not only does that one have the motors, it also has a polar scope.

If I wasn't saving for a new car, I probably would have had a punt at that one myself.

If you want a cheap 'GOTO' then get the EQ3 that James is suggesting and buy a AstroEQ(£90) from Tom Carpenter,although you will need a laptop etc to control the mount.

This is currently on UKABS....http://www.astrobuysell.com/uk/propview.php?view=74422

I would like the OTA...You perhaps the mount. Maybe we can strike a deal with the vendor?

Steve

Hello everyone, thank you for the replies. The above looks good, is this essentially what I was looking for only this has a better mount (or more suitable). Are there downsides to going second hand on a goto mount etc?

I've a house full of sick kids at the minute, so my heads in a bit of a spin lol, I'll look over all the posts more clearly in the morning and try and decide what I'm doing, not that I've much of a clue what I'm doing anyway as you can tell. Ideally I want a goto for my mak that's simple to use, that my kids can use eventually and that can take some nice shots within reason. I plan on a more substantial setup in the future, but sure don't we all.

      Dear colleagues,
      I am new in astronomy and got my SkyWatcher Star Discovery 150Pi WiFi AZ GoTo, however I am experiencing one big problem. When I try to align my telescope using SynScan Pro app on laptop or smartphone the telescope always points wrong direction. I do not have hand controller.
      I set telescope north using compass, enter latitude and longitude, but when try to align 1 star or 2 stars, telescope spins way, way off. When the star is in the South East it shows north east, or sometimes points absolutely wrong direction. When it is set on the north and object is 98 degrees east it goes some 30 degrees. It also points lower or higher.
      I am totally lost.
      I use 8 AA batteries.
      What I do wrong?
      How to fix this?
      Thank you.

      Hi - I'm a relative newcomer to telescopes with goto - still trying to figure them out.
      I have a problem with Goto on the 8SE.
      Alignment usually works (Not always, but usually)

      I believe my set up is correct - time and date, DST and UTC (It's currently BST in the UK)

      I usually use 2-star alignment (Currently, most convenient for me are Sirius and Procyon)
      Alignment usually succeeds, but goto just doesn't. The scope slews away, sometimes even to a completely different part of the sky from the selected object (I'm familiar enough with
      the sky to be able to identify several bright stars without assistance)
      Bizarrely, this happens even if the goto object is one of the alignment stars - how could it possibly not be able to find a star when you've explicitly told it where it is?
      I've read that goto sometimes doesn't work well on battery power, so I've aquired a mains adapter. No change.
      I haven't yet updated the handset firmware (I'm waiting for a serial-usb adapter.)
      Any help would be appreciated.
      Thanks

      Hi everyone,
      I'm looking to get a reasonably portable astrophotography set-up, using a 60-100mm refractor, with a suitable goto mount.  I spotted the Explore Scientifice exos2-gt with pmc-eight goto system, which looks like quite an elegant solution, and wondered if anybody in the forum owns this mount, and what they think of it's performance & usability?

      Hello all,
       
      this is my first post at SGL, and it will be quite long. I am not native a English speaker, so please excuse any mistake.
       
      I have quite some plan with my telescope mount and its goto control, and I am looking for some feedback and comments. If somebody else did a similar project, please let me know. And please feel free and encouraged to make suggestions, ideas, critics, etc.
      The story in a few buzzwords: Raspberry Pi Zero → direct control of TMC2209 stepper drivers via the Pi's Uart serial interface to drive my telescope mount. I am writing a software (optionally: open source?) to control the mount. The language will NOT be C, as typically used for Microcontrollers (I know for instance OneStep)
      I am using Kotlin, which is a more advanced JVM language.
       
      I think this should be enough information to filter the readers who are interested in reading the rest of my post.
       
      Now the long and detailed story:
      My professional background: I am a physicist, and did a PhD in EE (Power Electronics). Later, I became software engineer. Besides being fascinated by Astronomy, I am a tinkerer (Reprap 3D printer, electronics, …). I did grind my first mirror (a 6'' Schiefspiegler) when I was 15 years old, and I built the cookbook CCD cameras in the 90's.
      After many years without a telescope (study time, relationship, ... ), I settled down with my family, and I started to get back to Astronomy.
      Recently, I did by a quite a massive second hand mount: the “Vixen New Atlux” from another other stargazer in Switzerland. My opinion is that the New Atlux' mechanical design is superb. It has (had...) internal wiring, the counterweight bar can be hidden in the mount for transport, good polar alignment screws, it has an excellent polar finder with a dimmable LED.
      But on the other hand the electronics: two weak servo motors in combination with the incredible Starbook 5.... Seigh... the starbook...(!) it is, well... the mount is just superb, and no more comments about the starbook game boy, which shall rest in peace at the garbage dump.
      I removed the servos and all electronics, and I put 2 stepper motors into the mount, which are coupled to the gear with a timed belt. My original plan was to put an Arduino into the mount in order to control the steppers. I have an old goto Celestron cg-5 with Starsense, and it would have been quite easy to mimic - with the Arduino as interface – the servos of the old cg-5 and translate the Starsense control signals to my New Atlux. I can write C, and there is even an open source project called OneStep, which uses a Microcontroller in a similar way as I do.
      But I don't like to write C code anymore. In the 3D printer community, people need to use real time electronics to control the printer steppers. Due to the real time requirement, C with a real time microcontroler (Arduino & similar) are the only option for 3D printers.
      Do we need real time for our telescope? No. We don't need to control a lot of Motor accelerations and high speed control. For the telescope, we need to set the Motors speed precisely, and we need to drive to any position in an accurate and controllable and slow way.
      Then, there are new stepper motor drivers available with as much as 256 microsteps. The TMC2209 stepper driver , which is very well know in the 3D printer community, is not vibrating at all. It runs just smoothly, also at very low speeds. I do drive my motor with 0.25 rpm (sideral speed). In case of a slew, I can accelerate to 1500x sideral speed, which also would allow me easily to track the ISS. Wonderful.
       
      The current status of my project is:
      The mount is equipped with the two new motors The TMC2209 drivers are connected to the Raspberry pi GPIO Interface, and I can control them via Software. Theoretically, I could attach up to 4 motors with a single Uart interface (1 wire protocol). For instance, a focuser or a filter wheel could be attached. I selected Kotlin as language. Java also would have been possible, but I think for a new project, Kotlin will lead to a much more readable code. The TMC drivers can be driven via a chip-internal clock signal. Different to what the 3D printer community is doing (they use the step / dir pins, and create every single microstep with the microcontoller), I can send a “speed” signal from the Raspi via UART to the 2209 chip, and it will execute this speed for me without any further action. The only time critical issue was that I need to precisely count the steps that the 2209 stepper drivers executed. This is done via a GPIO pin, receiving its index signal (a pulse for every 2209 fullstep). Here comes the pain with Linux (non real-time) and the Pi: For user programs, it is impossible to guarantee that every pulse from the stepper drivers will be registered. But I cannot afford to have a step count drift over time. The solution was that I wrote a Linux kernel module in C. I wrote that I don't want to write any C code. Well, a few lines for the kernel module were indeed necessary. I can live with that, having in mind that the rest will be written in Kotlin. The only task of the Kernel module is to count every registered step at the Pi's GPIO input pins. This kernel module output is then mapped to a character device file in /dev/ for every stepper. In Kernel space, it is possible to register and count interrupts without missing even any one of them. From a hardware point of view, this is indeed everything we I need. The project cost so far: 2x10€ for the stepper drivers, 2x10€ for the motors, 2x20€ for the tooth belts and pulley, 10€ Pi Zero plus some peripheral expenses: Micro SD card, USB charger, and 1200 € for the used Vixen new Atlux mount. And a lot of time.
      I have so many ideas on how to extend the ecosystem of my software, but these ideas are for the longer term (maybe years from now on):
      Multi-star alignment. The alignment should be able to be updated continuously during an observation night. With a set of stars, it should be possible to calculate the quality of the aligment points, and e.g. drop them if they are errorneous. PEC correction (should be easy on the Pi) End-Stop support The polar alignment routines of today's goto scopes are quite good. But what I would like to have is some audio-feedback when I move the alignment screws into the right direction. Possibility to pre-plan an observation night (e.g. the mount could tell you that the Jupiter moon shadow will be on Jupiter in a few minutes). Record the telescope movements during the night in order to be able to tag any picture. The TMC drivers have much more capability than what I am using currently. For instance, they could be current controlled for slews in order to set the stepper current exactly to the value that it needs without stalling. This saves a lot of energy. The TMC drivers have a feature called “Stall Guard”. This could be used instead of endstop switches (for 3D-printers, this is done frequently). Advanced options for tracking: siderial, solar, moon speed, ISS speed. Tracking in both axis (e.g. to compensate polar misalignments of atmospheric refraction) or just in right ascension. Commercial mounts do not allow much customization here. With slow slew speeds, 5V input via a USB-C cable is sufficient for the Pi + Motors. Usb-C and newer usb battery packs allow to output a higher voltage via USB. With an “USB-trigger”, the input voltage can be selected to my needs. Higher voltage allows higher slew speeds, but consumes more power. Autoguider support, or even better: simply connect a webcam via the Pi's USB connector and do the guiding on the Pi The Raspberry Pi touch screen could be used for telescope controlls Advanced German mount limits and meridian flip control (e.g. a warning about a necessary flip when driving to a specific goto target). An Android App, connected via WiFi to the Pi could be used as display alternative Language control (have a look at Mycroft, an open-source artificial intelligence). "Hey mount, please slew to the whirlpool galaxy!" Control the mount via SkySafari and Stellarium The Pi has a built in camera interface. How about an open source auto align? The Pi could look at the stars to align itself, which makes a lot of sense. I did already order a long focal length lens and monochrome camera from Arducam in order to do some experiments (the standard Pi camera has 3.5 mm focal length and is not really usable, although star imagining is possible). My first observation site is my balcony. And there, the real Starsense does not work at all. It always spin-loops on 2 alignment positions where the sky is covered by the roof – how silly is that?. This can be done better. Further, Starsense is doing only a initial alignment. It should update its position and accuracy over the time! I think I could do this better.  
      Besides all my ideas, the first and most important focus of the software will be:
      Readability (therefore my choice of Kotlin), extensibility and open source. I like to have the Maths of the internal mount model clearly visible and understandable in the software. The calculations that are done within all our goto mounts are no rocket science. I admit, I am the nerd guy who wants to go the hard way and implement this from scratch.
      I am looking for a good project name, do you have any suggestions? How about QuickStep? this is possibly too close to OneStep and would offend the creators of OneStep?
      Does anyone of you have interest in joining my plan? Doing such a project in a small group would be more encouraging then just doing it for myself. And of course later on, I would appreciate if other stargazers would update their old mounts with my software.
       
      Any comments on my project plan are welcome!
       
      Clear Skies!
      Andy
