Hello all,

here is my first image this year! It is the Horse Head and Flame Nebulae. Between rainy, cloudy, snowy and windy nights we were having last couple of weeks,

there was one night of clear and reasonably steady skies. This image was taken that night. The image was taken using Moravian C1+ 12000AC OSC camera

through APM/LZOS 105/650 APO telescope. 80 sub-frames, each 3 min long, were combined.

Here is the link to the image details: more details.

Thanks for looking,

     Zoran

That's a keeper- beautiful colours and processing. I really like Moravian cameras as well- great driver stability. I was tempted by the IMX455 version however the attachment threads are somewhat non standard and I could see difficulties in coupling it to different telescopes.

Hello all!

Thank you for your comments and likes.

Moravian cameras are really trouble free. IMX455 sensor is a bit to big for my taste, but there might be one IMX571 based Moravian in my future smile.gif

Zoran,  Great mage.   Do you spend much time processing??    I like the nebulosity,  IC 435, NGC 2023 and Alnitak.  There is so much I want to do when I get my C1X 26000.    You are killing me my friend.    Keep them coming.    Joe

Thanks Joe,

I'm glad you like the image. I didn't do too much processing. Just basic stuff (using PI):

- background neutralization and SCNR (to get rid of pesky green)

- masked stretch

- mild local histogram equalization in brighter areas

- histogram curves adjustment

- boosting saturation

- mild noise reduction of darker areas (TGDV denoise)

I'm not too big in to processing either.  Mostly because I never do it past a histogram stretch or sharpening all in Registax6.

 

Thanks again for sharing,  Joe

Very nice image, great detail and color.

I'm curious -- where do the diffraction spikes come from, imaging with the refractor?

Thanks for sharing it!

Hello Paul,

I'm glad you like the image.

It is hard to tell about the diffraction spikes. On stretched image of such a bright star any minor imperfection

on any aperture in the light path will create diffraction spikes.
