  1. Hi Glyn, I have just bought the H18 and SE Filter wheel. I use powerbooks. The combination works perfectly with Nebulosity and PHD. I haven't any other imaging software just now. The shipped PC software with the H18 is not that great, but Nebulosity seems to be very popular and cross platform, as is the free PHD. In an ambient of 10C, (my fridge) without any airflow, I can get it down to -15C easily. I would say you could take it down to -20 or 25 on a chill evening with a little airflow. The filterwheel is especially cute, since it does not require a separate power supply. I now have 4 usb devices, lodestar, H18, filter wheel and mount, going into a 4 way hub extender. The extender sends USB2 info over cat6e cable and then back into USB. My cable is over 150 feet. It should go to 300 feet. My main issue right now is getting reliable communication between the mount and the computer. I have only just realised that the Synscan instructions are misleading. If all else fails, use bootcamp, which is where I started off when I just had the Meade LX200, DSI and Envisage.
  2. They say a picture is worth a thousand words! Wow, have you counted them yet? It is good to know that a combination works. I reloaded the FTD driver and finally got my macbook to work with the simple USB-UART cable and Stellarium/Mount. Still unable to get Stellarium to work alone or Equinox Pro to work at all, in any configuration. Well done for EQMAC!
  3. regarding PHD and Nebulosity linking - Dithering is another option of making the two working together but to quote the instructions: PHD Guiding is the popular freeware guiding package by Stark Labs. With it, guiding can simple as “Push Here Dummy.” With the PHD Guiding dialog, you can establish a link to Guiding so that the two packages can talk to each other. This gives you two powerful features. First, it lets you pause guiding during the download of your main image. Some cameras sensitive to interruptions on the USB bus and if the guide camera shares the USB bus, the feature. On another note - I just made up the FTD USB-UART (5V) cable and cannot get it to connect to the scope. This is the one recommended on the EQMOD website. Has anyone had any luck with this cable - it seemed more elegant and cheaper than the modules. I'm connecting orange - Pin6, black (pin 4-5) and Yellow pin9 on the DB9 connector- as per the instructions. regards Chris
  4. Still just on topic of pulse guiding - with the LX200, you can do automatic PEC training with an autoguider. Does anyone know if you can use Pulse guiding with an EQ6 mount to do the same?
  5. I second this - I measured 650mA during tracking, which after all is what it will be doing most of the time. Remember, with a lead acid cell to only use between 50% to 30% of its capacity regularly - dipping below this reduces its life and overall capacity.
  6. David - when you run Nebulosity and PHD, there is a link between them, which pauses autoguiding during download. According to Stark Labs, this is to reduce readout noise in the CCD. Starlight Xpress do something similar, they do not temperature manage during download either. Clearly, both are just reducing the modulation of the power supply. hope this helps
  7. Great answers on pulse vs ST4 - I suspect that the latency thing could be quite interesting. At 9600 baud, with all the other things going on, it could be a while before the mount starts to move. (BTW, I meant to say EQMAC in my question, not EQMOD...I have washed my mouth out now). I guess the best way to find out is to compare results. Something for the weekend....I think the EQ6 system is faster than the LX200 (meaning the response to the handset, start up, etc, an indicator maybe of the processor speed). Certainly on the LX200, ST4 was the way to go, but note the effect on sync with Stellarium. It is interesting with Stellarium. Not quite sure how that would happen. If the mount is tracking, the scope sends its position back to the planetarium s/w? If it lives in ignorance of its tracking errors, it will remain synced with the theoretical position in Stellarium. If you then issue corrective slews - then you are physically telling the scope to move to a different star position, which would make the scope position in Stellarium move away from the centered star.... the opposite to that reported. ST4 commands, assuming they are not logged by the mount as a physical change in desired star, should be transparent to Stellarium, since the mount will think it is still locked on? I feel a web browse coming on.
  8. I left a question on the general EQmod thread - I probably should have put it on this one. I have only just got by NEQ6 mount: If I'm using a ST4 output from PHD via Lodestar directly into the EQ6 mount, is there any advantage to using pulse guiding? When I had an LX200, it was always said that autoguider port commands were better for guiding accuracy over RS232 slew commands. Is Pulse guiding the same thing as issuing small slew commands or is it a unique feature of the EQ mount?
  9. OzDave - its working like a dream on its own and with Stellarium (I just realised - all my free software is working and all the paid stuff has issues!) - I use PHD and Nebulosity - which I link together to pause guiding during downloading. Is there a benefit to use pulse guiding through EQMAC rather than use the ST4 guide port directly from my Lodestar to the mount?
  10. The suggestion from Equinox's Darryl is to use Nextstar GPS setting. hmmm tried that already... back to double checking everything. Chris
  11. I used to write software in Forth, many moons ago. Wonderful work on supporting OSX. The fact it is free is even better. Knowing the amount of work that goes into this kind of thing you deserve recognition and our thanks. I didn't see a donate button, but if there is, I'll gladly give you reward with the recognition. Chris
  12. Sorry I meant to add, I thought ASCOM drivers were only for Windows?
  13. Hi - to answer the questions, I'm using OSX, not Windows in Bootcamp, so I assume I do not need Eqmod, which is a PC program. The serial adaptor is the Keyspan HS, recommended by Equinox Pro, which as you quite rightly point out can be a sticky point. This is supposed to be the best. I have others I can try too. Since the hardware chain works with EQMAC, then clearly the hardware is capable - ( I didn't get it to work with Stellarium on it's own, only with EQMAC running too.) I need to do some more digging. Keep the ideas coming! Chris
  14. I have just bought a NEQ6 and use OSX for my astronomy. I have not been able to connect Equinox Pro planetarium software to it through a USB to serial adaptor which is then plugged into the Synscan handset. I have proved the hardware works with EQMAC and EQMAC with Stellarium - which happily slewed and sync'd. Has anyone got this combination working....or does it require direct communication with a USB to UART connection? I have tried using the Nexstar GPS setting, Nexstar and Meade basic. Equinox pro is working with my LX200. Any clues will be appreciated Chris
