spent a bit more time processing this with a few more processes.  Came out a bit nicer looking i think.

Very nice image.

Thank you!!

Hello!  

Been some time since I posted anything here.  Been out of the Astro loop for a while, but finally got the bug again, and am glad to be back. 

This the fish head IC1795 which is the tail of the heart nebula.  I had a few consecutive nights to gather data so I took advantage of it. 

I had a hard time getting used to the starnet process in pixinsight so I think my stars have some artifacts around them, but I can continue to figure that out as I learn more about it.  I also think the HA focus may have been a bit soft, or my combo right now just doesn't have as good of detail as i thought it should have.  Constructive Criticism welcome.  Thank you!

Taken with an AT8RC, Atik 383l+, Baader Narrowband 36mm filters on a MACH 1 GTO Mount.  

5 hours of HA - 1200s
3 hours OIII - 1200s
3 hours of SII - 1200s

I am so sorry about this delayed response.  I have been out of the game for a bit here.  

I use a filter wheel and focus with each filter using an autofocuser.  It pinpoints the best number for the stars in the image and sets it for me every hour.

Still playing around with it.  Added a synthetic OIII channel due to bad weather.

I still havnt gotten the colors on this one to look like the hubble pallet no matter what i change ..does it require all three narrrowand filters to achieve this?  

Thank you i appreciate it.  

I started out with a dslr but never had a chance to try a HA filter with it.  The only thing I did was self mod my t3i.

 I'll probably remap and play again to see which brings out the most detail for the colora shown.  

I am going to add OIII and see what that brings.  Had a tough time with colors I think I had 5 different color combos I was playing with.

I finally got some SII Data to add to my HA data and got them processed.  5 hours 20 mins of data.   So here is my version.  Mapped the HA to green and the SII to Red and used the HA as a LUM.  I like the definition between the green and gold dust so i left the colors instead of changing to the HA gold like the modified Hubble.  Thoughts?  

8 x 1200s HA

8 x 1200 SII

I was able to achieve 45 second expos using the ALT AZ mount and a 6" SCT, just go higher ISO take darks to reduce noice.  Also wait a while between shots that way the scope can settle between shots.

Thank you I was quite pleased for a first time!

This was 15 images ranging from 30 seconds to seven minutes. 

This is my first nebula other than m42.  32 minutes of data no darks.  1600ISO. Unmodded t3i, 8" Orion Newt.   No Coma Corrector Or LP Filter.  Only used Photoshop CS2 to process.  I'm quite pleased as a first try.

Nice single shot.  Take a few of those and stack them in DSS and see what you can come up with.  I am still a beginner as well.  I was told to save the format as a PNG, and it will show a lil more detail.  You should be able to get anywhere from 60 to 120 seconds from a good alignment, so if you take a few at 400, a few 800, a few at 1600 iso and stack em,  you can get a lot more to come out.  Also make sure you are shooting in RAW.

Streteched a bit much but here it is a bit brighter. 

Guess I should open it in photoshop and stretch it.  Its a lil dim now.

Here is the PNG file that I was told to try.  Definatly no halo using Pixinsight.  Now I just need to pay for the program cuz my trial is almost up lol.

I am going to try reprocessing on pixinsight see what I can come up with.

And the halo is from me doing a gradient removal in photoshop not know how to do it but watching a quick video.  Its sort of cool, but it would be better if I had gotten rid of the halo.  Funny the halo didn't stand out until I posted it up.  Much more noticeable here then on my screen.  Strange.

lol ive got gas sorry I have to laugh.

Here is my 10 stack of 1 hr of data various iso and lengths.  I could figure out how to get rid of the gradient properly but here is what I got so far. 

A few were guided shots and a few were unguided.  I just forgot to delete them .

Here is my first processed prime focus short stack of Orion nebula.  I had a lot more colorful pics but they were too grainy to use and I could not et registax to align properly.  Apparently I wasn't aligned very well as I could only get 15 sec subs.
