PushToCam Manual

Thank you for using PushToCam iOS app. It is an easy way to find your way in the space.  PushToCam is different from FinderCam in a significant way. It does not use camera to align to the star or to guide telescope to target. Without needing the phone camera, you will not need to bent your body or neck awkwardly to look at the app when your phone is attached to the telescope. The phone can be attached to the  telescope  or binocular in any orientation. It can be along the  o ptical tube or at an angle to the tube. However, it must be aligned so that the app can accurately point to objects in the night sky.

Thank you for using VideoStack for Planet iOS app. It is an easy way to stack your video frames into a single photo.

You have to take a video on your camera, upload to your computer, and use PIPP > Registax > GIMP to crop, stack and process the video frames. Now you can do it on your phone conveniently. Direction: 1. Use videoCam iOS app to take a short video of the planet with your telescope. You will need at least 130mm telescope to see some details on Jupiter. In the app, adjust the exposure, frame rate and ISO so that you can see some details on the planet and start to record a video. Save the video to your phone album. Alternatively, you can use phone native camera to record a video. However, it has less control over the video parameters.  2. Trim your video on your phone to ...
