you got the best equipment to learn from already. Sometimes through MaximDL and all the software is not enough yet. Just you need more advanced techniques on photoshop or other softwares. Smiley

My 5 cents tips only.

Regards.

Thanks Tommy for your 5 cents tips.  Please take it to your account.

I'm mainly using Maxim for combining images and photoshop for final touch up already and i'll explore more and more on this two softwares. 

For now i'm learning how to get the best raw images....many factors involved...bad seeing, telescope tracking, guiding, focusing, etc.  I need somebody to discuss more on that, imaging and processing technic.  Maybe u are the right person to talk on that.

I will show you a photo of M42 same angle like yours, taken by one of my amateur astrophotographer friend in singapore. You can use his photo as a reference.

Will PM you the link of the photo. Then I will talk more about this astrophoto with you later. For an example, equipment he used....and so on.

Regards,

Tommy

Hi Kayzack,

Those are nice images. shocked

Have you do image calibration for all image? Are you take each channel only a single shot? Any stacking progress?
According to your exposure time, you press down some weak signal from the target a lot. Actually most of the image can be more detail, especially those nebula.

The M42 taken by both RC & TMB can be more stunning if each L:R:G:B taken in few minutes of a single shot.

Semalam saya ke rumah Dr Rowi di KB. Selepas jamu selera hari raya, kami di jemput ke observatori beliau; ada weapon baru lah. evil

Malangnya langit tidak mengizinkan ambil gambar.

beliau berkata bulan januari tahun depan mungkin cuaca lebih elok.

buat sementara itu kepada sesiapa yang berkelapangan dan hendak mencuba process CCd astro images

click disini

so there is no correct photo  tongue

BTW rather than shooting 4 sets of photos  a B/W CCd camera and a DSLR I was told makes for a great astrophotography combination. Maybe Kayzak and other sifus here would like to give their observations and elaboration on this approach. huh

cheers
