I'm trying to update my v3 handset prior to selling the mount. I need to update the bootloader from v1.0 to v1.7 before I can upgrade the firmware from 3.12 to the newest version. I've tried following the instructions in the bootloader download but the upgrade loader refuses to install anything.
Before I realised I needed to update the bootloader, the synscan loader v3.3 just showed 255 255 255 where it should display the handset software, ie 3.12.
Can anyone advise what I'm doing wrong?
The handset won't run the mount probably because I had a replacement motor control board a few years ago., I'm guessing. It worked fine before that. I've been using eqMod for years.
I have Skywatcher Synscan V3 working with my EQ6 without problem.
I've lately flashed firmware v.3.39.05 and tried using it with my Skywatcher Virtuoso. I have problem with 2-star alignment. After manually move the mount to point to the first bright star, align; then choose the 2nd alignment star, the mount will slew to the sky very far away from the 2nd star. After I managed to complete the 2-star alignment successfully, the goto accuracy was very bad. It always placed my scope quite far away from the targets. I've tried the whole night and gave up.
I then begin to wonder whether I have to flash the hand controller with the firmware for Allview mount (v.3.09.06) instead. Anyone can share your experience on this?
I need the combined brains and experience of SGL please, I'm stuck!!
I've been an astronomer for 30+ years and have had several Skywatcher telescopes over time, including my current EQ6-Pro for about 10 years. This is largely irrelevant to my post, except that I hope to convey that I'm not a total novice to getting telescopes to work as they should...although I feel like I am today.
I recently picked up a very battered early-version EQ6 with 10" reflector, cheap. It hadn't been looked after well and when I first fired it up...it didn't fire up at all. No life. I noticed that the power supply wasn't suitable as it only had a 0.5A output. So after digging out a spare one from the cupboard outputting 12V 1.25A, the Synscan chirped into life.
My first attempt to slew the mount was met with a horrible grinding noise and refusal to move. Needless to say, I didn't do that again. Clearly the motor/gear train was seized. So a quick look on the internet brought up the amazing website posted by Astro Baby, with step by step instructions on how to strip and rebuild an EQ5 or EQ6 mount. This kept me entertained for a couple of nights, followed by a lovely smooth running mount slewing in RA and DEC as it should. Many thanks Astro Baby!
Last night was the first clear night, so I took the mount out, popped the 10" scope on (had a full respray, new finder, new focuser and laser collimation), and awaited the fall of darkness. Here comes the rub.
I roughly aligned the mount on Polaris, not bothering too much for this first test. The Synscan controller is (unfortunately) running Version 2.05, which is one of the early versions that are not flash upgradable. Although I didn't realise this until after I had downloaded all of the upgrade files from OVL's website. 🙄
When I picked the first alignment star (Capella, rising nicely in the north-east sky), the mount did something completely unexpected and slewed around to east of the meridian and pointed somewhere in the direction of Alcor! What the ...? After several unsuccessful attempts at carrying out an alignment, I gave up and looked online for any similar problems. I've checked and confirmed all of the following things are correct:
Location - yep as per my Cumbria coordinates Date - yep in the right format (mm/dd/yyyy) that good old confusing American format Time - yep I tried with BST and without BST (not really expecting any significant difference) Made sure the mount was in the "parked" position (weights down, scope pointing towards Polaris) before turning the mount on Tried all sorts of initial alignment stars, but none of them were in the right area of the sky at all Unfortunately, I haven't been able to find anything on the web that offers a solution.
I did wonder if I've done something during the disassembly of the mount - but I know the mount doesn't have encoders on it. I didn't see anything that looked like a counter of any kind?
I don't think it can be anything to do with the power supply...surely that couldn't introduce such a wild error in pointing? It's like the handset has no idea where it is.
Any help would be much appreciated. This was going to be a second mount for me, but at this rate it's going to go on the scrap heap.
I did think about buying a V3 handset, but didn't want to commit another £120 in case it's something in the mount itself that's the problem.
I'm trying to connect SkyWatcher Synscan to my MacBook Air via wifi adapter using EQMac v2.0.0 beta3.
According to the release note of EQMac v2.0.0 beta1, it supports wifi as well as serial connection. However, I couldn't find any document for wifi connection.
What I'm trying to do is..
1. Establish Wifi connection to "SynScan_WiFi_####"
2. Configure following connection in EQMac's Preference
Connection Type: TCP/IP
IP Address: 192.168.4.1
3. Close Preference setting
However, EQMac console is still gray out..
Appreciate if anyone share how to configure EQMac for wifi or alternative application/tool to connect Synscan to Mac via wifi.
I am looking at the Canadian Skywatcher website and reading about the SynScans dobonian base models, comparing them just for fun. (I always wonder if someday I'll be sitting while sketching)
8" SynScan GPS 1 548USD / 1 996CAD (F5.9)
10" Synscan GPS 1 970USD / 2 541CAD (F4.7) +545 +2"
12" SynScan GPS 3 049USD / 3 932CAD (F4.9) +1391 +2"
14" SynScan GPS 3 831USD / 4 941CAD (F4.5) + 1009 +2"
16" Synscan GPS 5 269USD / 6 796CAD (F4.4) + 1885 +2"
Just looking at price, size and F ratio, I find this interesting especially for the first 3 models the 8", 10" and 12"
In these deals the 12" is F 4.9, is it a big difference with a F5 honestly? With the same eyepieces I use right now with my F5, Xcel LX, Starguider, Explore scientific 68 and 82 and orthoscopic eyepieces, I don't fell any need for a coma corrector very much.
If anyone ever compared a F5 with a F4.9
Also, looking at the prices, the 10" it not much more expensive then the 8", but at F4.7, I believe it needs a coma corrector which will raise the price of a few bills and you get more glass behind the eyepiece.
(Simulation) My first goal would be to upgrade to something I can sit while sketching and that has a tracking system, that's mandatory. The 3rd thing, the aperture has to be 8" or more naturally, It's the least important need in the 3 but it's still there.
The choice is not really easy:
8": PROS: Not to heavy, generous F5.9 focal ratio, decent price, not too high to watch while sitting CONS: No aperture upgrade.
10": PROS: interesting 2" aperture gain, probably still low enough to watch while sitting CONS: F4.7, Coma corrector required 200$GSO / 400$ Baader, more lens behind the EP
12": PROS: Maximum and massive aperture upgrade, F4.9 perhaps no coma corrector required. CONS: heavy weight, perhaps too high to watch the zenith while sitting, quite expensive.
if you want to share your opinion, what telescope do you guys thing is the very best of the 3 and why?
