I have just got myself a Celestron C11-A XLT (CG-5) scope and a SkyWatcher EQ6-R PRO SynScan mount. I have an ASIAIR PRO and the ZWO ASI462MC planetary camera. I want to use my Nikon DSLR for deep sky photography. Now I’m looking at auto guide options. I’m thinking of getting a ZWO ASI290MM mini and am wondering if I should get a guidescope or an OAG? Which is better and why? I don’t have the Edge HD C11 so would the view on my scope be good enough for an OAG? If I go for a guidescope what would I need there? I’ve seen 50mm and 60mm scopes but some people have mounted huge guidescop

Hi All, wondered if you could help me make sense of this ... new HEQ5 - belt modded by FLO, all feels good, minuscule backlash but strange guiding. Admittedly first time using it but baffled. Failed calibration see image below and guiding seemed to be Ra and Dec following each other. Stars look ok ish (@ 1500 mm ) Needle galaxy is poor as only about 10 mins each in RGB note - it was hazy and did keep losing star in OAG Thanks for looking PHD2_DebugLog_2020-05-19_221608.txt

I'm sure this is just one of many hundreds of posts about correct spacings on here - I think I've just about got it but I need to confirm a couple of things with folks who have more experience than me on these matters. My scope is a Skywatcher Evostar 80ED-DS Pro - one which I'm sure anyone here is familiar with and needs little introduction. I'm using the accompanying field flattener/reducer, which requires 55mm of back focus. The off axis guider I plan to use is an OVL Off Axis Guider - it is thin enough that in combination with my camera I should have the required back focus provi -
After a lot of experimentation I have just managed to achieve focus on both my oag and Atik 383l. However I am not convinced that the image from the guide camera is orthagonal to that of the Atik even though both are square to the RA axis. I did have to chop about 5mm off the prism turret to achieve focus. Could the prism have moved? If so will it affect my guiding accuracy? How do I check how much it's off by? The prism appears to be square and flush with the turret, will removing and resetting the prism (using the small grub screw) make any difference. Any help or advice would be g

Hi very new to guiding and using an OAG on my CPC9.25 SCT and need some help. A few weeks back I managed to capture 10min subs of IC434 without any real issue. I had my CPC9.25 mounted on a wedge, did an EQ North Align, then Polar Align > Align Mount routine. I slewed to a target and set about getting both my guide camera, Lodestar X2 & my DSLR both into focus on my attached Celestron 93648 OAG. My setup as follows: SCT > OAG > DSLR via Baader 2958550 Protective T-Ring The complete OAG thickness calculated from the manual is 66.8mm, comprising (SCT Adapter

Hi I’ve recently got some shiny new kit, and last night was the first clear skies here when I had the opportunity to try it all out. This is not my first time observing, so I’m well prepared for unexpected issues, but it is my first time ccd imaging. There was lots of learning, including; cable management needs to be better, I (still) never have the right USB cable, and the focus tube needs some mechanical refining to address slippage. But the problem I’m not sure how to solve is one of focus. I bought the SW Trius 814 kit (Trius 814, mini usb filter wheel with OAG, and Lodestar X

As SGPro are actively promoting the FocusLock focussing system from Optec Optical & Electrical Products. I was wondering if anyone is actively using this system. Preferably with a Lodestar or LodestarX2 and OAG, using the Lacerta kit. Steve -
Hi guys, you've probably hear this before but i have a 250PDS on an NEQ6 and I've been Finder Guiding but now I've brought a SW off-axis guider but for some reason i cant get focus in my EOS 450D. I've wound the mirror up as much as i dare but i still cant seem to gain focus. Does anyone out there use one or do you have any suggestions i could try? Thanks

Hi, Contemplating going for a TS OAG9 to use with my 350d, and also potentially with my ST-2000XM (back focus is just short enough to fit it between the cameras and an MPCC - 12mm spacer is needed for the SBIG so it'll just fit). I'd probably want to use my ASI120MM with this (already own it - suitable for guiding with), and concerned about the guider fouling the imaging camera. Wondering if anyone has the above arrangement with the SBIG at all and can confirm it fits/limitations/etc? Thanks!

Hopefully a simple question. When inputting the Focal Length for an OAG in the guiding details in PHD v2. Do I simply input the telescope's Focal Length as this is light path that the guide stars travel through? Thanks.

Hello again troops, and sorry to have to invoke the power of your collective intellect once more. Should be the final time for a while, and will bring Jaffa Cakes to the star party for anyone who can assist I'm finally about to push the button on the camera. I'm not quite decided between the 460ex and 490ex, but for the purposes of this question, it is immaterial. I image through my SW120ED DS-PRO. I have the dedicated 120ED field flattener, which has an M48 thread on the camera end. Optimum sensor distance is 55mm give or take a millimetre. So I obviously need a filter wh

Hi All, Apologies for what may seem like a stupid question, but if have a QSI 683 WSG which has a built in OAG which i use for guiding all the time. I want to try imaging some comets but i'm guessing this is not possible with a OAG. I do have a 60mm guide scope, but wasn't sure if differential flex would come into play as my main scope is around 1.2m F/L Any help or recommendations would be greatly appreciated. Rich.

Hi guys and girls, So I've decided on a 9.25" SCT for my upgrade as initially I want to continue visual observations whilst dabbling in imaging with my DSLR. Then I will look to increase my set up. The question I have is would the AVX be capable of dealing with a imaging set up, whether it be a guidescope or off axis guider? Assume I will be using a monochrome CCD camera with filter wheel when I say imaging setup and not my DSLR. OR should I down size the scope to an 8" as upscaling mount beyond the AVX isnt really an option unless i look at the EQ6. Your thoughts please. -
Hi Does anyone feel able to recommend an OAG + Coma Corrector combination that achieves the correct spacing and good reliable results when connected to a Nikon DSLR? Cheers Mike

Sorry I could not find this by searching the site ... Does anyone know if the TS 9mm OAG will fit between a Baader MPCC and a Nikon camera with the correct 55mm spacing? And if so, do you know what adaptors to order with the OAG to achieve it? (BTW, I've sent an email to TS and I am waiting for a reply. I'll post it here when I get it in case anyone else is interested. ). Thanks guys Mike

Hi everyone, I would like to use my QHY5L-II with my OAG. However, it seems like even at 2x Binning its not able to see stars. I've used Dark library, but no use even then Any help will be appreciated.

Greetings everyone. 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 w -
THIS ITEM HAS NOW BEEN SOLD. This listing is for my personal camera (Kayron from Light Vortex Astronomy). It is a QSI 660wsg-8 monochrome CCD camera with the onboard 8-position filter wheel and Off-Axis Guider (OAG). The camera has been extremely well kept and cared for. I am supplying them in the original QSI pelican case, alongside the power adapter (with EU and UK plugs), a new USB cable, the QSI Allen wrench set, the 2" adapter for the camera and the guiding cable. The camera's condition is as-new. The QSI 660wsg-8 requires a single USB connection to control both imaging and -
I've bought a second hand Celestron Radial Guider OAG. It looks quite old, but is in good condition. I intend to use it with my C9.25, f6.7 focal reducer and Canon 600D dslr. I have a standard Celestron T-Adapter-SC #93633-A and Canon AF T-Ring. These fit together nicely and all is well. I just tried fitting the T-Ring to the Radial Guider OAG but they don't fit together. The thread appears different on the OAG to the standard T-adapter. I was wondering if anybody knew what I need to marry the two parts together? Or do I need to buy a different T-ring? Any help would be appreciated

http://www.celestron.com/astronomy/celestron-radial-guider.html I've been offered one of these second hand and wondered of anyone has one, or knows if it's compatible with my setup? I have a Celestron C9.25, Celestron f6.3 focal reducer, Celestron SCT T-adapter with T-ring, and Canon EOS 600D DSLR camera. I'm new to imaging, and wondered what other peoples opinions are before I agree to buy it. I've read a few posts on here that say the distance between the DSLR sensor and the focal reducer is critical, and should be 55mm (I might have this totally wrong). Is it really that critical? and does
