IC443 Jellyfish Nebula

Post by nexusjeep » Sun Jan 19, 2020 2:43 pm

Actually had a clear night so got to image for the first time in 2020 actually the first opportunity since the end of November as the weather has been awful. Had a non eventful session for a change as nothing went wrong which saying it means that the next time everything will go pear shaped.

Equipment
Avalon M-UNO mount + EQDirect cable
APM LZOS 780/130 refractor + Riccardi 0.75x Flattener/Reducer
Altair 60mm Guidescope + GPCAM290MM Guide Camera
Imaging Camera ASI1600MM-Pro at -20c
Filters 6nm Astronomik Ha / Oiii / Sii
Software Sharpcap Pro/ PHD2 / Stellarium / EQMOD / Astro Pixel Processor + Photoshop CC

Exposures Ha 40 x 180s / Oiii 40 x 180s / Sii 46 x 180s gain set to 300 offset at 50 dithered every four frames.

Integration total included time 6 hours 18 minutes based on the best 80% stacked using APP

Bortle 4.5 - 5.0

Very nice, Nick!

It was on my to-do list but due to my small FOV it would have required two panels. It is rapidly becoming meridian-challenged but I don't have an unobstructed view of the west. It will have to wait until next year.

Thanks Brian,
I am lucky in that sense as other than houses and the observatory is towards the middle of the surrounding homes I am unobstructed for 360 degrees and when the telescope lifts out of the roof on the frame I made it is about 10 ft up in the air so I get a reasonable amount of sky. Also with the new mount I can track fully east to west or west to east without having to do a meridian flip so once on a target it just continuously tracks all night.

Cheers
Nick
