Crab Nebula (James) and my attempt at the Flaming Star Nebula
Robert Chandler
James,
I tried this target last night also and got pretty much the same view and not the colourful image as I have seen previously and from social media, so I gave up and moved on. I thought it was my lens fogging up, wonky connection on the dew heater
Trev attached is my attempt at IC405 – Flaming Star Nebula from last night (screen capture from live stacking on ASIAIR pro app). I have not processed this and it comprised of around 50 x 120s of imaging time using the ASI294MC OSC camera on the RASA 8.

Took this last night of the Crab Nebula, a cropped version of 70 x 20 seconds ie 23 minutes in total stacked by DSS, with an Esprit 80ed and ZWO asi533 MC at -10C. The target is really too small for the 400mm focal length but I was pleased
to see a bit of detail in the nebula.

Hi Robert your unprocessed sub of the Flaming Star/Olympic torch is nice. With 50 subs processed you should have a really nice image. Re your attempt at the Crab, do you use a dew shield with your RASA? I don’t know if that’s possible with a camera screwed to the corrector plate at the top. I was imaging last night too and it was cold! A Schmidt Cassegrain without a dew shield will be a magnet for dew on the corrector plate. A dew heater on its own will probably not be enough protection on such nights.
Cheers

Hi Robert
We’re having some very good nights at the moment and the Moon is still relatively out of the way, so a good time to image!

Thank you Trev for your comments. Work and weather have not allowed me to image recently. Now that Galaxy Season is with us I hope to start imaging soon.

Hi Robert, That is nicely framed and well focussed. It looks like you need some more exposure to bring out the detail though.
