Actually got it working now. Went onto ZWO support and they got me to change the settings on the tablet ASIair feed by altering the STA settings. thanks for replying .

Cannot connect CEM 26 onto ASI air v1 using a tablet. AsIair sees the WIFI signal from the mount handset. HBX 849 . connecting to the ASI air signal going into the Scope icon trying to select mount but it only shows CEM 26 EC not just CEM 26 . Selecting Ethernet, 10.0.0 etc selecting buad rate actually tried them all . But does not connect. i have asked on ASIair forum , tried contacting ZWO support. has anyone actually done this and can you guid e me through it please.

Brown Dwarf and Trailer Trash - Bingo it works and slews to target using the Go to hadn't tried it so thanks for pointing me in the right direction. I just tried the arrow buttons, !!! Now I,m fairly confident I can Plate solve and use Goto etc , that's whenever I can next see a star !!!

Has anyone installed the CEM 26 in APT and got it to work,if so how? i,be tried in both WIFI and USB but no luck. I,be got the Ioptron commander on Ascom and it works both ways on its own. i then go into APT and connect scope with Ascom it identifies the mount CEM 26 then if you go properties it says that the mount is being controlled through the Commander so you say OK. It recognises the mount and puts in the RA and Dec positions but when you try and use the NSEW controls it comes up error message and nothing happens.

thanks for the advice. Then I would need a 2" tube lens fitting to go into the Crayford with an SCT screw thread so I could then fit a spacer to get the 105 mm focal length and screw camera to it taking into account the focal lens position? Would this still work? As the focus isn't great I as its about 5 mm too long, I thought it would still focus but as suggested the f ratio would maybe 0.6 anyreason whyfocus should be out.

Cheers, this is where I,m at present. I,be read it's 105 mm back focus which is what yours look likes. I,ve got the Crayford Motorised so I still get that ability to auto focus . It's 110mm so it's out a bit. I,m going to get a thinner 2" fitting with a 42mm thread so can fit Camera directly onto it so will get it around 6 mm closer . Hopefully that is enough. Will keep everyone informed. What's your thoughts on that!

Cheers Robert, from camera focal point to reducer lens is that 105mm .is that right.

Cheers mate.

What size of thread is on the Celestron 6SE SCT visual back ?

Has anyone got the Shoestring FCUSB to run on Autofocus in a free app. NINA,APT,Sharpcap etc. I,m not looking for repeatability re stepper motor. i know there are several comments on forums where it cannot be done because it's a 32 bit driver,not64bit as generally required. NINA has a relative Focuser ability but I cannot get it to work. I followed someone's advice and downloaded Bahtinof Grabber and in here you can run it in Poth mode for an Ascom driver and use 32 bit driver. Downloaded NINA as 32 bit and thought relative Focuser through Ascom would be the answer. So as the apps are changing etc has anyone got a solution please?

Szymon i realise this is an old post however i,m now at the position to try out both the Hitec and or Shoestring FCUSB to gain Autofocus . How do I go about it? Can you assist please. i,m looking at Autofocus through any free app so NINA comes to mind. image shows the shoestring however I,ve also got the Hitec unit.

Does this mean that the 105 mm from the reducer to the camera focal point? Would this also take into account the travel of the Crayford, or go for 105mm ish and then use Crayford just to nail it.!

Thanks very much guys for coming back. Here's the setup and thanks to Callup and M40 for the distance. Stash _old ,s link shows the Reducer fitted to the FC on the SCT with a spacer between the reducer and the camera. However that means yourbrelying on the OTA focus knob to gain focus. On my Celestron 6SE you cannot get a great focus on it hence going with the Crayford. Now I know what I,m trying to achieve with the distances I,ll experiment.

Cheers Mike I,m trying to run before I walk, however by asking the questions now I can hopefully save a lot of frustrations later.

Sorry forgot to add that if I use an UHC filter with DMK41 or DMK 21 would this be of benefit on some targets? forgive me if these questions seem inappropriate or silly but we all have to learn somehow.

You've mentioned filters. If I,m Mono with a DMK41 I haven't done it yet due to weather but I have a Astronomix Planetary 642 filter. Yes it more for Planets naturally but it does cut out unwanted light and goes into some narrowband areas. Would I be cutting out on too much of the imaging info from the source to get any other benefit? i,m using a Celestron 6SE SCT with a 6.3 reducer to bring it to f6.3

Thanks a lot guys you've put some effort into this topic and wrote out quite a bit,I,m still absorbing it all.

I,m looking to put a 0.63 Celestron Focal Reducer on my Celestron 6 SE to reduce FL to speed up OTA for imaging in EAA. Do i put Reducer directly onto scope,then fit Crayford to this then ZWO 120 mc onto this. all assuming I have the right back focus to do this. If so I can use motor focus on the Crayford. or do I have to put Crayford onto scope,reducer ontomthis then Camera. Or forget Crayford and install reducer directly onto scope fir spare and the camera and use the course original focus knob ?

Can I ask what the 20H2 means?

Cheers

Does the ShoestringFCUSB work with Windows 10 as I've seen someone's comment that it doesn't work on Windows 7 . will the downloadable drivers work in Win 10 .

Cheers mate

Hope this is the correct place to ask the question . can you use a Skywatcher DC motor on a Crayford type Focuser controlled by the Shoestring FCUSB controller.? I believe the DC motor has a phone type connector but don't know if the Shoesstring controller has the required cable(don't know what it uses) it is a 9vDC battery however the Shoestring is 5 vDC control but says you can get away with 9vDC. has anyone used the two together and any issues to be looked at before I buy both parts. i,m assuming Ascom drivers etc on Windows 10 will work. any advice appreciated.

I,ve been reading about Mono cameras for EAA due to having a couple of DMK mono,s. However a lot of people are saying one of the benefits of EAA is the ability to see coloured images. Relise it's up to the individual to make their choice however are there any benefits between them?

Is anyone using a DC driven relative Focuser in ATP. They have an emulation tag in Tools but I really need some instruction please. i,m using the Homebrew Skywatcher Focuser. naturally wanting to get a better focus. I get close focus take a 2 sec image then measure HFD move Focuser with a measured amount take photo and measure again and repeat until its either better or worse and then repeat in the other direction ,logging each detail.Then going back to best Star measurement. What do others do or is this the best way?
