    Default Thor's Helmet



    This is my fifth astrophoto ever taken and processed. It is my favorite one. It just pains me that my processing is so terrible. I hope to get better at this soon. I envy those that can magnify and display huge details, but this is the best that I can do for now considering.

    Takahashi FSQ/SBIG/OIII.........I'm trying to figure out how to reduce the huge amount of noise in my images. Any suggestions?

    Nice looking stars and image.....

    What are your exposure times and software you currently use to capture and process with? How many images stacked etc......quick overview of your processing steps etc?

    5 minutes of exposure per. i try to do multiple with different filters, but even then, I don't really have a clue as to how stacking works. So basically, I am only using the best image out of my set. I use several different scopes depending on where I am at, and who'll let me use it, so I don't know much about the software except that all of them spit out .fits.

    I process like a noob because well.... I am. I convert the color in maxim dl. I don't even stretch it, because I don't know how that works. Then I take it to photoshop and mess with the different adjustments. Shadow/highlights, color balance, curve, and some noise removal. I know, very anarchic. I don't know what I'm doing at all. Maybe a suggestion for a book? lol

    Sorry to be such a mess, but I figured that I would share my mess with you.

    I would look at the free Maxim DL videos online at the website for starters, they have a few good tutorials there.

    I can not recommend enough Adam Blocks dvd series for computers on photoshop, they really set me straight with photoshop....tremendous help...


    I would do at least 40% darks to amount of lights you do...Stretching is the magic you will pull out all the fine details.

    For LRGB the L channel normal gets extra exposure times from what I have seen....more than other channels......all my cameras are one shot color ccds or dslr.

    Ron Wodaski has great book, I have one of his original older series ones The New CCD Astronomy Home Page

    With some research on processing methods, and practice you will grow proficient in no time...........Many will jump in with some great websites and links to help you out with lots of free info.......

    I will be jumping in with my Maxim DL this season, bought it year ago, been waiting for weather and observatory final touches before I commit fully to Maxim DL, it will be new to me, currently using Nebulosity, ImagePlus, and few others...but Maxim DL appears to have everything I want with my setup.....so hopefully I will be able to pipe in more on Maxim DL fairly soon.

    You are off to a great start! A bit of good reading material will take you very far very quick!!

    Here is link to a few Maxim DL tutorials Cyanogen Imaging Products from Diffraction Limited

    It was not too long ago, I felt lost with the imaging stuff, stretches, various formats, stacking etc, with a few good resources the lightbulb finally clicked, many imagers will tell you the same thing, most of work is post process work, feel like I am constantly learning something new all the time, and have very far to go myself yet. What you are getting now is showing good data and nice round stars...Clear SKies and keep the images coming! Image is great and I would be very proud to have been able to do that just starting out!!! A stretch will reveal all the details......

    Found one other link which gets into LRGB workflow

    Astrophotography CCD Imaging Tutorial

    This has some good info covering all the steps and what is happening at each step.

    I do not see any stickys covering LRGB workflow.
