yes but the scope is in an observatory with only view of the sky , so no objects to focus on

thank you very much for all the comments , I will attend to the points the next time we get clear skies. Bosun 21 I have no idea how it managed the polar alignment, its not perfect . I spent today checking the gear again in the house and both cameras focus ok , but I had to use the laptop and a guidescope. Then spent a few hours trying to workout the eaf settings don't know if this is right the coarse focus only does 1 revolution and the fine does about 10.5 so I think the eaf does 5700 steps end to end so presumably I need to set half this number.

forgot to mention that the main camera works fine in video mode and in reply to 900sl I tried to setup in the day but can only use a guide scope on a camera tripod and using the laptop but can't get images only black or white screen also have no way to take photo's of the mobile screen. DO I understand Backfocus , yes although a dealer did give me wrong information about the focal point of my focuser as 140mm but I have worked out that the 533 focus point is around 113mm and as I said when its on the main scope connected to my laptop and using manual focus it works fine

okay so maybe I'm a bit dim. My first question is in preview and live, should both camera's show images, because they show nothing , even I have altered all the settings . polar alignment has been successfully carried out on the ASIAIr . next question, when trying to get the guide camera working the asi keeps telling me to adjust the step. but it seems to make no difference. the focus on both camera's is good , as I have disconnected from the ASIAIr and connected to my laptop using Asi studio and I get very good result. My thoughts on this are that something is not compatible , my reason is that first on my phone the view rotates on turning it even though it is disabled in the phone settings and second, the app continues to run after the mini is shut down by removing the power! and I have to go to phone settings and disable the app. regarding the guiding , I believe it has something to do with my focuser in that it only has 20mm of movement, the course adjustment is only 1 turn. The mini when focusing goes from full in to full out when trying to set guiding and keeps returning the adjust step after I have adjusted all the settings. The setting for the EAF is slow not fast. I have had good result from the 533mc camera before I purchased the ASIAIr mini, maybe I should abandon the mobile and get a tablet. thanks for trying to help

I have had the ASIAIr mini for a while now and think I am missing some setting as my guide camera and main don't work on the mini. I have connected both my air 120 and 533mc to my laptop and both work ok, but I get no images at all when connected to the mini. I have the mini on my Skywatcher Explorer 190MN DS pro along with an Artesky guide scope which are aligned and mounted on a Skywatcher EQ6-R pro mount which is accurately polar aligned. I also have the ZWO EAF connected to my focuser. I have tried to polar align using the mini and plate solve but neither work. If I insert eyepieces to the finder and scope using the hand controller it is accurately aligned with objects ie Jupiter and then I can put the cameras in but connected to my MacBook, all is good using ASI Studio, but if I then revert to the mini , nothing!!! However if I select the video option, then I do get images from the main camera?? I have the mount powered with a 10amp psu the mini is powered with the recommended 12v 5amp power supply and I have tried to power the 533MC camera with a third power supply. So now I am stuck with no more ideas, would be great if someone knows an answer to this dilemma, Thanks in advance.

Thanks all for the good advice. As I thought that the MacBook I was using does not support the necessary software to control the cameras, I will update after I have setup a windows pc

So last night , nice clear night I tried to image Orion nebula, which I have done successfully with my Canon EOS6D mk2. All I managed to achieve with the ASI533 was two stars visible but I had to use ZWO ASI Studio

Yes I have a solar filter for the front of the scope

seriously that is what the ASI recorded

The Sun

Hi is there someone on here who has the above scope with an ASI533mn camera connected who can help me with a focus problem. I have tried various combinations to connect the camera without success. I have the lacerate octo-plus 2" for newtonians. The photo is out of focus I assume. Thanks

Thanks Michael, your info is very useful. I have tried what you said and connected the 120 direct to the laptop in the daytime and then the 533 and then both and through the hub and all is working fine. Problem now is we have constant cloud cover so can't try at night yet, but as soon as the sky clears will try through the scopes. What software do you recommend using on the laptop as you mentioned sharpcap and phd2

thanks for the replies, My guide scope is an Artesky ultra guide Mk2 60mm which the ASI 120 fits in, I hope to be able to control all with a windows 10 laptop and I have a usb 3 powered 4 port hub. So far I have not been able to see any images on either camera. Which of the softwares is the easier to setup, I did try PHD2 but got lost with which mount to use. Before spending more cash on ASI air I would like to see if what I already have works.

Hi all I could do with some advice on the easy way to connect my guide scope with ASI 120mm mini and Skywatcher Explorer 190MN with ASI 533mc pro, all mounted on a EQ6R-Pro and which software to use and how to connect all this together

Many thanks for the help will post after I try again when I get clear sky
