A diffraction spike is caused by how light bends or diffracts around an object or in this case the support beams in your secondary mirror in reflecting telescopes. I don't know of other ways to do it with the Gimp (it is possible to use a custom brush, but then one need to adap manually the size and color of the brush to intensity and color of the light source). A diffraction spike is the light you see extend from a star in your astro-images.

However, I got these double diffraction spikes, but only along one axis. choosing 4 spikes gives 4 additional shorter spikes). Hey guys, I was imaging M20 last night, had the collimation really good, and focus looked great, with the bathinov mask. Plus, it gives additional spikes that one cannot remove (i.e. The current way to do it 'automatically' in Gimp ('sparkle' filter) is not straightfoward and requires a number of trial/error before finding satisfactory results. It also seems to depend on the scope design. My particular interest is for astrophotography (those spikes are ingeneral created by reflecting telescopes, and astronomers using refracting telescopes or regular SLR lenses like to add spikes in postprocess), but I guess such a filter can be of artistic interest for other types of photographs (e.g. of 3 - Beginner Question - Star Diagonals and Erecting Prisms - posted in Beginners Forum (No Astrophotography): I never had a problem with spikes with the WO prism.,ymmv., I think the prism roof can cause a diffraction spike with some of the cheaper Amicis. A simulation of a Bahtinov mask diffraction pattern when focusing. Finally, the planet’s brilliance and point-source nature make it ideal for experimenting with diffraction. The animation below shows you exactly how the diffraction spike pattern looks while focusing your telescope with a Bahtinov mask. Both guides were designed specifically for the RASA 11 and functional with a Photon Cage. The Max Diffraction guide has clamp holders if you use a Photon Cage to align with a support, giving you 90 degree spikes aligned with your sensor. It really messes up large stars, but also impacts the shape of small stars. The help I'm looking for is what you think is causing the messy one-sided diffraction spikes on my stars (see enlargement on large star later). What I would like in Gimp is an efficient and easy to use filter to generate diffraction spikes (star spikes) on point lights. Cotton vains across the front of your scope will help you generate the diffraction spike effect when photographing Venus. The Max Diffraction guide has slots to perfectly clock the mount to the outside pins on your RASA 11. Below is a quick 1.5 hrs RGB capture of M51 that I took with my Newtonian. Depending on the exposure length, however, the spikes around the fainter objects may be too dim for the detector (usually a CCD chip. I don't know if it's the right place for feature requests. In fact, all objects on the image will have diffraction spikes.
