Keeping the diffraction spikes in a final image

#1

Post by jazzin »


I use PixInsight to process my images and It seems every star cluster I've imaged, the diffraction spikes get killed during processing but I would like to keep the diffraction spikes in my final image. Is there any certain technique or process in PixInsight that allows you to keep the diffraction spikes or is it just a result of using to many processes while trying to improve your image.

Thanks

Try changing the high sigma rejection on stacking.
Personal equipment: TEC 140 F7 on Astro-Physics Mach 1 mount. Camera QSI 683ws7. Guide with Vario guiding scope
Shared equipment through Star Shadows Remote Observatory through PROMPT/ CTIO/Chile 16" RCOS 16803 chip
Shared equipment through San Diego Astronomy Society 14" RC with 16803 chip on a paramount
Software (for my stuff) PemPRO, SGP, PHD, Focus Boss, ASCOM, and Pixinsight on the other end.

Hi Jazzin - Have you had any success maintaining the diffraction spikes?

Are the diffraction spikes still there after stacking but before processing?

This, also maybe turn off large scale pixel rejection.
