Horsehead, flame, dust and.. a strange star
      #5589716 - 12/26/12 01:04 PM

Here's my attempt at the Horsehead and the Flame nebula. Canon 40D central d.s. on Televue 102 f/7, 2.5 hrs. of global integration.


At the bottom right you can see a strange star with spikes, unusual for a refractor
Here a link at a CROP of a raw file.
The spikes are similar to those of a bathinov mask, they appear in all the raw and in one star only. I can't understand..

Wow! You controlled that naughty Alnitak very well. The other star (HR1950) is very interesting indeed! Usually it doesn't give headaches...

I am still suspecting that it might have to do with Alnitak. In my attempt, there was a strange reflection approx at the same distance from Alnitak, though it was not on top of HR1950. Look carefully right below Sigma Orionis.

No matter what this turns out to be, this is a great image.

Happy holidays

Sedat

Many thanks Guys, glad you like my pic!!
Thanks Sedat, maybe you're right, but I find it strange that the reflection is perfectly centered on the star in all my raw during 2.5 hrs. also I use dithering and the star isn't on the same exactly position in all the frames

Beautiful image, Carlo. I think the Flame nebula is actually on fire!

Really nice session, Carlo.
Colors are a little bit pushed but I think that the overall results is extremely good.
I have the same star effect as your in all my sessions and just only on a single star at bottom left of the images. This is probably due to some dirty stuff on the Baader filter.

Best Regards,
RC
