Help! I have a Skywatcher EQM-35 PRO GoTo mount for which I am unable to get the star alignment right, whether I use 1 star, 2 star, or 3 star alignment. I can get it polar aligned without any problem, but when it comes to star alignment it is way out. Choosing Sirius as the first star to align, the scope slews to the right general direction but about 20 deg. lower and slightly to the east of where it should be. The mount is perfectly level. I have checked, and double checked, all the settings, longitude and latitude ( N 50:41:46 W 3:13:53), Date in mm:dd:yr format, Time, Time Zone (0), Elevation (25m) and Daylight Saving Time (Yes). I am at a complete loss what to do next. I am getting close to chucking the lot into the sea!!! Before I do that anyone got any suggestions?
I have a SkyWatcher AZ-EQ5 mount. It’s all working fine, except I have an issue with alignment. This applies whether I’m in EQ or Alt-Az mode.
I set it up using one or two star align without problems.
However if I use the handset to GoTo another object, I usually need to do fine tuning adjustments to centre on the new object. But the mount disregards these adjustments, so if I use the GoTo system to centre on a nearby object, or revisit the original object a second time, it’s still off by the same amount.
How do I tell the mount that I have centred on the new object and that it should now be aligned with that object ?
My iOptron MiniTower has a feature that does exactly this – once set up correctly and aligned, for each new object I go to there is an “ALIGN” option, and if I use this it now knows the correct position. Can I do this with SkyWatcher and Synscan ?
So it seems that after my clear out of the "Big" scopes life circumstances are meaning it is less and less likely that I will be able to do any astro which is a shame indeed.
I am therefore putting my little "Grab 'n' Go" setup up for sale
This is an absolute little beauty of a telescope. Really excells on planets and lunar work and solar (appropriate filters must be utilised - never point a telescope at the sun unless you are an experienced solar astro buff!)
I was very unimpressed with the flimsy tripod that came with the scope and managed to source a purpose built and absolutely solid portable pillar mount for it. Its is steel construct and is ingenious in that it allows levelling of the feet and also levelling at the plate too thanks to the utilisation of three springs and wing nuts to allow for easy adjustment.
Not only is the pillar great for the levelling option it has but it also has removable legs to allow for easy transportation to dark sky sites. The legs simply slid into place and the steel cable is tensioned by hand through easy use of the inline bolt brackets.
This is a whole package deal - perfect for anyone wanting to start astro or just have a great little portable setup.
SO, whats included? Included in this sale are the following:
- Skywatcher Skymax 127 Maksutov OTA - mint condition, no marks of blemishes
- Purpose built solid, tubular steel pillar levelling mount
- Baader Planetarium Hyperion 8-24mm clickstop Zoom Eyepiece
- Skywatcher 9x50 RACI Finderscope
- Greenwitch Astronomy original all weather telescope cover (you can't get these anymore!)
- Skywatcher Synscan Al-Az mount and Hand Control
- 12 V power cable
- Original factory fitted straight through 8x30 finder scope and bracket/shoe
- Instruction manual
This has all been kept in my observatory under the cover throughout. It really is in excellent condition and cost me quite a bit to put together so I have priced it competitively. Please no offers.
Is collection only and (of course) covid safe exchange. I prefer bank transfer as payment.
Hi everyone I am new here, I live in Perth Western Australia (bottle class 5) and have just brought my new set up. There hasn’t been anyone in the area I can talk to about astrophotography so tried to do it all myself online and I fear I may have incorrectly purchased some things. (I tried to get things one at a time for budget purposes)
I have this set up
heq5, evostar ed80, .85reducer & corrector, evoguide 50ed, zwo 120mm mini for guiding and just my canon 200d mkii for the imaging.
The telescope, I think I may have brought something that’s not great for imaging and that’s all I’ve wanted to do.
can you please provide a better telescope alternative that would be suitable for all my other gear without having to buy like a new mount etc. I’m thinking just a slightly better scope not too heavy, opinions would be much appreciated 💖💖💖 xx
With new mount and upgraded scope features, now looking to venture into imaging.
Before I start, I'm not looking to get feedback on polar alignment, mono guidecam, better imaging cameras, etc; this is more a 'dummies guide' setup discussion! I'm not expecting to get great images at this stage, just more the options available, getting over some issues, so that I can jump outside on a clear night with an ideal, foolproof(!), setup for either imaging or visual as time would permit and what may work best for me. As you may guess from the topic name, I'm a mac user (Macbook Pro) and would rather keep to this if possible (whilst I do have Windows (and Ubuntu) via parallels, I'd rather not use these).
I've got a setup which has worked well for visual, and obviously want to have a couple of 'staple' setups that I can use depending on expectations of night observing or imaging. So far, the best one for me has been the Skywatcher Wifi Synscan controller, which has worked a treat with my Android phone - I use the Synscan app to complete alignment and GOTO stars/planets/DSO etc, or Stellarium_plus after completing alignment. This removes the need for the Synscan Handset and any USB cables to the mount altogether. But I don't know if this will work for guiding.
That then brings me to my issue on mac - connecting USB(A) between Macbook and Handset, I've attempted to control the mount through Stellarium. Trying each of the available connections (/dev/tty.usbsetial-1420, /dev/cu.usbsetial-1420, and just for sake of it, the /dev/tty.Bluetooth-Incoming-Port and /dev/cu.Bluetooth-Incoming-Port) in the dropdown menu under DeviceSettings/SerialPort, I cannot get the mount to connect (well, more like selecting the telescope and clicking the "Start" on the TelescopeControl just results in the spinning icon and I have to Force-Quit Stellarium and start again with the same result each time. Annoyingly (for fellow mac users!), Parallels/Windows/Stellarium connects and controls the mount fine! As the mount is the newer "pro" type, I also have a USB connection directly under the hand-controller RJ45 and AutoGuider ST4 sockets, but using this still results in the same issue. Another issue I have seen is that when I unplug the USB from the computer when connected to the handset, the date on the controller jumps significantly - for example, last night at ~23:30, I was transported through the local wormhole galaxy to Jan 2048 according to Synscan! Obviously unplugging isn't going to happen during a genuine session, but just wondering if this is a possible issue somewhere?!
Any other mac users connecting USB directly to the SW 'Pro' mounts?
Software wise, would folks generally suggest steering away from Stellarium towards KStars or SkySafari(Plus) for controlling the mount?
Can the Wifi dongle be used for controlling mount from computer (any OS) or do I need to go USB either to handset or directly to mount?
Is there an issue in using Mac USB to the telescope compared to 'straight' Windows (i.e. PC/laptop with Windows instead of virtual)?
Anyway, back to topic... I've a Nikon DSLR to use for primary camera at this stage, which would be triggered independently from guiding software. PHD2 is my hopeful choice of guiding software (is EKOS with KStars similar?), with T7C guide-camera on 240mm f/4 guidescope, and at this stage, I can confirm PHD2 at least connects to the camera on OS-X. There is an ST4 port on the camera, but having read several topics, I think I want to pulse-guide directly - is this correct or is ST4 best for this setup? This sorta comes back to software and connections - my understanding is one of the following cable setups for guiding (as a minimum) :
Guiding-camera => USB(A) => Macbook => PHD2 => USB(A) => SynscanHandset => AZEQ6
Guiding-camera => USB(A) => Macbook => PHD2 => USB(A) => AZEQ6
Guiding-camera => USB(A) => Macbook => PHD2 => Wifi => SynscaWifi Adapter on AZEQ6
[using ST4: ST4_on_AZEQ6 => Guiding-camera => USB(A) => Macbook => PHD2] (no additional connections needed if ST4 is used)
Additionally, I'd like to use an observatory package, say Stellarium/KStars/SkySafari, to select objects and drive the mount, then use guiding software to keep good 'tracking'.
Where in this train does EQMac fit in, or when is it used?
What about the 2019 addition to EQMod (ASCOM Alpaca)? Can this be used or is it already in other packages?!
For Windows users, how does EQMod fit in (if I go down route of getting Windows laptop for controlling things, is the setup similar to above?
There may be bits in the above that repeat, and for that, I'm sorry, just want to get across the message that I'm new to the guiding but haven't quite settled down into the software/hardware I'm expecting to use for 'goto' and 'guiding'
For a mac user, what setup and software are folks using for guiding and observatory softwares for the newer USB-on-mount 'AZEQ6/EQ6-R Pro' mounts from SW?
