Hi everyone !
It's been a long time since our last visit in your forum...
We missed you... but we're back
Nothing has changed in our setup and it is working perfectly, almost 20 nights every month
Here is IC2118, the Witch Head Nebula. This is a 2 pictures mosaic.
We have added some H-alpha because we thought it could be a good idea... and it was ! Actually, this part of the sky is full of Ha but we are not used to see the Witch with red. We are more used to bleu
Ok, here are all technical informations:
- APO observatory in San Pedro de Atacama, Chile - Alain Maury's Space Obs
- Takahashi TOA 150 refractor
- mini-OHP mount with MCMT
- Apogee Alta U16M camera
- Astrodon L R G B Gen2 filters
- Ha=10x40' - L=24x20' and R=G=B=6x20' - everything x2
- shooting, guiding and preprocess: PRISM v9
- process: IRIS, PRISM v9 & CS6
