Giant Cat's Paw - NGC 6334 in SHO-ish This image is made of about 150 frames 1200 second each, with Ha, OIII and SII 3nm filters, collected over several nights with a small refractor over the past few weeks from our backyard in Whitsundays, Australia. Large resolution image: https://a4.pbase.com/o1...

Gum 85 in HA_RGB In this image of a less familiar but interesting object, Ha was used for detail and RGB for colour. Total integration is just over 52 hours, data was collected with a 105mm refractor from our backyard in a coastal town 20 deg South of the Equator. Full resolution: https://cdn.astro...

Eye of Creator - four narrowband channels Helix The image is a blend of 0.55 HA_SNO + 0.1 HA_HNO + 0.35 HA_HSO. I know, not really scientific, but pretty. Integration (203 hours of useable data in total captured during 40-50 sessions over several months across two winters): HA = 194 x 900s + 157 x ...
