M45
Posted by Mares on Sunday, November 03, 2013 3:49 AM

I wanted to test my new DSLR camera and choosed the star cluster M45. When imageing this star cluster, its recommended to use a refractor (ex. ED APO) from 80 - 150 mm (with guiding). I was using my C9,25 and was getting very close to the cluster. 20 frames x 60'' are stacked in DSS and proceesed in PaintShop Pro X4. 

Equipment: C9,25 and Canon EOS 550D.

Nice job. 

Did you take any darks, flats, or bias frames?  They would improve this already good image a lot.

Thank you, Chris.

 

No, i didnt take anything of this, but you are right ..... i should. Its not too late to add darks and stack the frames one more time. Its only to take some darks outside and add them in DSS with the lights.

I`ve tried to add darks, but DSS does only support raw-files. I know raw is recommended to astro-photographing, but this time i was using jpg. On my next astro-image i will use raw. I have reproceesed the image above and reduced the noise. The heaven is also a little darker, but i think this edition is better.

What do you think ?

I know the data wouldn't be a s good a RAW but is it possible to convert the JPGs to TIFFs?  Then you could do the same for Darks.  I know DSS will accept TIFF.  I'm not sure since I always shoot RAW and save as either TIFF or JPG later, but Photoshop may be able to save a JPG as a TIFF.

Yep, its possible to convert the files to TIFF (also the the dark files), but it takes a lot of time to convert each file.

The files are now converted to RAW. 23 x 60'' (lights) and 5 darks are stacked in DSS (ISO 1600). I`m not satisfied with the image, because the stars not are in perfect sircel, a little out of focus and also have some deviation.

Don't give up on the image.  I think you have enough there to do a surprising amount of adjustment in Photoshop.  I know you can round those stars a bit,  and cure the gradient for sure.  But since you started out with JPG files I'm not sure stretching the histogram will be of much effect.  But it may be worth a try.

I dont use PhotoShop, only PaintShop Pro X4 to processing astro-images. Otherwise i think C9,25 has possibilities to take quite good images of M45 (ex. guiding).  Here you can see my best image of M45 from october 2011. Exposuretime = 16 min.(s) with ISO 800. Camera Olympus E-510 DSLR.
