- Once you have an even light source, follow these steps. Loosen clutches and move (or slew) your mount to/near zenith. Set tablet upside down, directly onto the top of the dew shield. Plug in USB power to onboard hub or any power bank, turn on to medium or higher brightness. Remember to remove the tablet before slewing to another target!!!

- Flat frames are part of calibration files that are useful in pre-processing astrophotography images. Flat frames are meant to evenly distribute the light during astrophotography and produce a clear sky image. Producing …

- Flat frames can be captured by imaging an evenly illuminated light source, such as the sky at dusk or an LED panel. Along with vignetting, flat frames tend to reveal any dust motes that may have settled on or near the sensor or filters (although with the fast speed of the RASA, dust motes don’t tend to cause issues).

Using a Flat Field Panel for Astrophotography
- https://astrobackyard.com/flat-field-panel/
- A flat field panel can help you create a uniformly lit flat frame to correct uneven field illumination in your astrophotography images. This issue can arise whether you are using a DSLR camera, CCD, or dedicated astronomy camera. Previously, I have used the DIY “white t-shirt method” to take flat frames.

- Good flats are those with a proper exposure, where the histogram for all R, G, and B channels peak at about halfway, ⅓ to ½ from the left edge. There is no fixed exposure length for flats. Instead, look at the histogram and tune it by changing the brightness of your light source (or add an extra T-shirt if this is the method you are going to use).

- Flats can remove the dark shadows cast by dust motes, correct the light fall-off towards the edges of the field of view caused by vignetting and will compensate for variances in pixel sensitivity across the camera’s sensor. Flat frames must themselves be calibrated and stacked to avoid the risk of introducing artefacts of their own.

- Flat Frames, Histogram And Light Meter On a DSLR you’ll see the light meter. It’s underneath the aperture and mode on the camera. It goes from -3 up to +3. In this example we’re going to say -3 is pure black. 0% let’s say. +3 will be pure white (100%). For flat frames we want 33-50% luminosity.

- As I understand it, flats are essentially a way to make sure each pixel in the CCD camera is seeing light/dark in the same way. Flats are to average out the way pixels see and react to light/dark. All that is very usefull to eliminate artifacts like vignetting, dust motes, etc.
