Hi Alex, The polar axis alignment is fixed at the time you set up the mount. This is not always exact. SharpCap has a tool that enables you adjust the mount by using a camera on the finder. This is partly manual and doesn't use any plate solving. Its a physical adjustment. I check the polar alignmen...

Hi, I have my system as JNOW for pointing. As i understand, the plate solve uses J2000 and this is converted to JNOW - im fine with this. Which coordinate system is expected by the sequence planner and advance editor, where the coordinates can be entered [Move mount to] ? For example, i have a list ...

Hi: I was in a recent ZOOM meeting that was discussing fast frame rates for IMX174 cameras. I have the QHY174mGPS. I use it for deep sky imaging as well as occultations. Typical settings are: Occultations: 2x2bin, Gain 380, exposure 100ms Deep Sky : 1x1, Gain 180, exposure 60 sec I use gain 180 beca...

Hi Robin/All, Thanks for the discussion. I have now used dither, and find the image moves too much, so the frame edged are shifted, and clearly different stack lengths. I think i should be able to adjust this in the settings, but any tips welcomed. (see example attached) In the manual, it indicates ...

Hi Robin, It was a pleasure to meet you at an AS meet recently. Just to pick up on dropped frames, I use the QHY174mGPS with SC 4.0.8604 and i get a few dropped frames with most recordings between 5 and 50 fps (even with ROI). So i would like to expand the logging data. Based on your answer above wh...

Hi, My Pinnacle Dazzle A2D converter displays my WAT-910HX integrated video signal in SC. So i was wondering if i could use an integrated frame to plate solve and sync the mount ? Has anyone tried this and found it works ? I've not yet attempted this... The idea is to use this approach to find the s...

UPDATE: I tested the camera at full frame (2x2bin) using 100, 50, 20ms without dropped frames (usb traffic=0) and 900x600 (2x2bin) at 10 and 5ms again no drops (SSD).

So the problem has not re-occurred, and I will continue with the current (most recent) camera drives.
Thanks: Tim

Hi Robin, The USB speed is set to 1 or 0. The last three SER recordings (all recordings after the update) had less than 1% drop according to Tangra at 20 and 10 fps. I'll obtain some star field at different frame rate and check again. Thanks to Christian for the driver file, and link to QHY. I now s...

When i installed SC 4.0.8604 i got a message that driver 18-3-30 should be replaced by 21-9-9 or later. I downloaded what i thought was the updated driver: QHYCamerasDriver-V22.01.19.0 for Windows10 NewIO dot exe. I am now dropping a few frames at 20 and 10 fps. This shouldn't happen. I looked on QH...

Hi Robin, I see the Run Recent... selection, but this doesnt put into into the editor. How do i change the default program to edit? (which should have been my question!) For the sequence to work i need to change the start time and duration. There is no problem to load it, but since there is a sequen...
