Planetary imaging using BYE

[hdoraisamy]

I have a Canon EOS Rebel T6 which is connected to an 8" Celestron SCT scope. In the BYE manual, it says that I can get better resolution by using the in camera 5x zoom. What exactly does this mean?

I have been pressing the "5x" button in BYE prior to imaging, but do I actually have to enable the 5x magnification on the camera body too in order to get the benefit of improved resolution?

Also, do I need to make any considerations in BYE if I use a Barlow lens?

Thank you

The LCD display on the back of the camera is smaller than the camera sensor. This means that the camera has to downsample the image to display it on the LCD display. Using 5X zoom takes part of the full image and displays it on the LCD display at full resolution. The way the Canon software that BYE uses works is to download the same image that would be displayed on the LCD display for Frame & Focus and Planetary imaging.

If you put BYE in 5X zoom mode and you see the image magnified, then the camera is in 5X mode. In that case you should not touch the camera to press the Zoom+ button.

Your camera and scope should work just fine with a Barlow lens. I would recommend a good quality 2" Barlow, however. Using a smaller Barlow will only illuminate the center of the field-of view due to the smaller diameter of the lens.
