Rosette Nebula SHO

RosetteSHO

I had captured some Hydrogen alpha and combined it with my old DSLR data. It became one of my favoriteĀ images. I was able to capture the other two common narrowband filters, Oxygen-III and Sulfur-II. I really enjoy the SHO/Hubble Palette. Narrowband false color images from the HST started my love for astronomy.

The Jellyfish Nebula

The Jellyfish Nebula.
This ended up being more challenging than I thought. The oxygen III was less prominent than I had expected. I ended up needingĀ over 9 hours of OIII! This is a bicolor image. I hope to add some SII and do a full Hubble Pallete.
