M45 quickly (Blue Mountains)

Imaged captured quickly last night with teeth clacking and body shivering. Very quick stacking and processing. I shot the Seven Sisters for Rhonda.

the Pleiades in one-shot colour

Tele Vue NP 101 refractor, Losmandy GM-8 with Gemini mount on pier, FeatherTouch electronic focuser, StarryNight, FocusLynx Commander. Guided through a Tele Vue 70 Ranger with Orion SSAG and PHD2. Canon 40D, Backyard EOS. 5x150sec, ISO 1600, daylight white balance. Dark frames applied. Canon DPP, Deep Sky Stacker, Adobe Photoshop. North is bottom-left; east is bottom-right.

Happy with this result although I need to do more work in post-processing.

Thanks, Phil!

I consider something of a milestone where I used someone else’s imaging rig but sorted hardware and software issues and obtained a decent result.

Also, my first time using auto-guiding.

Pleased with focus.

Very happy to see nebulosity around the stars: IC 349 aka Barnard's Merope Nebula or aka vdB 22, the wispy tenuous clouds surrounding Merope star; IC 1990, aka vdB 20 and Ced 19, the wispy Reflection nebula surrounding 17 Tauri; Ced 19h, nebula surrounding Asterope; vdb 23 aka Ced 19l diffuse reflection nebula around Alcyone; and Ced 19o, Dim wispies surrounding Atlas and Pleione.
