Flat photography led panel lights generator#
The Artesky Flat Field Generator was designed in Italy, and the team approached me about demoing this product at NEAF. The model I have is the Flat Box USB 250mm unit, which connects to my PC for complete control over the settings.
This device was designed to make taking flat frames easier, and deliver reproducible results that can be used for future imaging projects. I’ve been fortunate enough to receive a demo version of a dedicated flat field panel for astrophotography, the Artesky Flat Field Generator. While this method is often useful to help correct an uneven field in your astrophotography images, it has a number of drawbacks including having to wait until daylight to complete the task, and inconsistent results. In order for this method to work, you must find the right balance of t-shirt layers between your telescope’s objective, and the daytime sky. Previously, I have used the DIY “white t-shirt method” to take flat frames. This issue can arise whether you are using a DSLR camera, CCD, or dedicated astronomy camera. A flat field panel can help you create a uniformly lit flat frame to correct uneven field illumination in your astrophotography images. One of the most challenging aspects of capturing flat frames is producing consistent, accurate results in terms of brightness. It also removes dust and other artifacts that may be present in the optical train.
When used correctly, flat frames can correct the uneven field illumination of your light frames, which reduces vignetting and gradients significantly. To capture a successful flat frame, you need to evenly illuminate the field through your telescope or camera lens. Flat frames are calibration files are used in the pre-processing stages of an astrophotography image.
