I recently got the eq3-2 synscan mount to start with astrophotography. I first wanted to get the eq5 goto mount, but it is way out of my budget, and I could not find any good used ones that would fit my budget. Furthermore, I hear a lot of people talking about how eq3-2 is not that good for astrophotography, but what are some things I can do to improve the mount. Cheers guys.
I have been attempting to update my SynScan V3 Hand Controller from V3.08 to latest version. Handset bootloader is V1.7.
Unfortunately I just get the message “Can not connect to SynScan hand control”. I have looked at numerous forums and tried everything that has been suggested (including older versions of firmware installer), but getting nowhere.
I am using a Skywatcher SynScan USB Adapter (purchased from Bristol Cameras) and installed the driver from the Skywatcher website. The adapter shows in the COM ports and says it is working properly.
I have tried different computers (Win10 and XP) with no joy.
Can anyone help, or is there anyone in North Aberdeenshire that has successfully updated their handset willing to give mine a go (once travel restrictions, etc ease)?
I recently scored a great deal on facebook marketplace and bought Skywatcher Skymax 180 mm Maksutov-Cassegrain Telescope (f/15) with EQ6R-pro mount. I understand that long focal length telescopes are more suitable for planetary imaging. However, as I am tight on budget, I would like to use the same scope for deep-sky astrophotography. I have Canon Rebel T5 DSLR camera that I am using for taking images. Without autoguiding and a decent polar alignment, I can get ~30 seconds long shots without any star trailing, but that's not sufficient for imaging objects like M51. I would like to be able to integrate longer, say few minutes, thus would like to purchase an autoguider. Here are some specific questions I have.
1). The telescope comes with an 8 x 50 straight-through finder. If I were to use it as a guidescope, what type of image integration time can I expect? Has anyone done autoguiding for f/15 scope with an 8x50 or other finderscopes?
2). If the integration time will be an issue with the 8x50 finder scope, I am open to purchasing an off-axis-guider. However, considering the narrow field-of-view of Mak-180 telescope, I am concerned about not having enough photons from guidestar for autoguiding. For instance, with my DSLR camera, I need to integrate 20-30 seconds to see the nearby stars in M51. What type of OAG and camera would I need to autoguide with my scope? Are there affordable cameras (~$200) that would do the job for me? Would ASI120MM Mini Monochrome (~$150) do the job? What about OAG?
I plan to use phd2 software for autoguiding rather than relying on the build-in guide port on the mount. Instead of integrating for hours, I am planning to do DSS stacking of few mintues long multiple shots, hopefully this will put less strict requirements on the autoguider.
In case this information is relevant: with my current setup, I have no issue pointing my scope to a desired deep-sky object, track the object within the field-of-view of my DSLR camera for hours using the mechnical tracking of the EQ6 mount. For instance following is a single raw image of Ring nebula taken with 30 seconds shot. But it is not enough for generating high-quality images.
Thank you in advance for your help.
Having convinced my wife to get me a SW Az goto mount with a wifi dongle for Christmas off a well know auction site all was going so well with set up, config of Stellerium and Ascom until I tried to update the motor controller firmware...
I am now getting the exact same error as detailed here, although on the slightly older version of the mount. It looks like the solution below was to use a Skywatcher Synscan wifi adapter, which I already have, so I don't think this solution is going to work?
So, my laptop (Win7) can connect the mount via Wifi and using the SW wifi Motor controller updated it looked to clear the ROM and then started counted up in % until I got the "Firmware update failed. Cycle power to motor controller and try again!"
Trying again I get to 1% before getting the same message.
Will leaving it unconnected for 4hrs drop it out of the firmware cycle? As I don't have a hand controller can I try the update again via a USB/RS232 combination straight into the laptop without a HC present? I have read about wifi channel inference on other forums, but I don't think that's it, so any suggestions would, at this point be really gratefully received.
The only saving grace is that the weather isn't conducive for looking upwards, so I have a few days to try and sort this before my wife expects me to be outside and using the mount.
Finally got skywatcher ED50 finderscope to work with diagonal. Now have nice little travel scope!!!!!!!!!!!!!!!By Mark Daniels
So after a couple of months faffing about, trying stuff out and trawlling the net for ideas, i think i have a solution that works. I wont take credit for basic idea but have refined it to make solution less hassle.
So i read on post here and on some american sites that the use of a barlow would sort out the focusing issue and it did
however it requires using a barlow between the diagonal and the extension tube. This inceases the length and makes for a wobbly affair. In a moment of enlightenment i wondered if i could combine the barlow and the diagonal to make one unit. I have other skywatcher scopes and so spare barlows and diagonals. I took the lens from a barlow screwed it to the diagonal and had ago
hey presto it worked. Whats more using the supplied spacer provided with the ED50 the scope now focuses in the center of travel of the focuser so no issues with lens length etc.
was up last night looking at jupiter which was small but clear, split a double or two again small but clear and took a look at andromeda which was not bad considering the moon was out.
because of the barlow the magnifications were doubled obviously but being 242 FL the FOV was the same as my 102 travel but wiegt wise probably 1/4 of it
give or take a few units
for a holiday affair i am extremely happy and i will be using this scope lots between now and my visit to La Palma in the new year in preparation
picture attached for those interested and i will up date as i work out some king of red dot finder fir it
