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 :thumbsup:

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 :question:

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

And a must see: the full sized image !!

Wow - that's great & it goes really deep -
on the full size version - I can see dozens if not hundreds of tiny galaxies in the background -
many of grand spiral design.
Do more!

cheers

Thanks alpal ! :)
You're right, the background is full of things to discover... and as you said, some of the galaxies have a nice spiral shape !
We'll do more, for sure !

Fantastic. The red from the Ha makes for a wonderful backdrop to the image.

It certainly is a detailed high resolution image of the area, so much to see :D

Thank you all !!
That's right, the H-alpha is adding something to the picture.
And it's strange to see the Witch Head only in blue after that :)
