Plato

Posted By Tyler Allred
Hi all. Here is an image of Plato from two nights ago. The seeing was pretty bad, so I went long with the AVI and got enough decent frames to get a respectable image. I know I can do much better, but not today! 8)
Cheers,
Tyler

Saturn at f/25

Posted By Tyler Allred
Here is a quick shot of Saturn from the other night. This was taken the same night as the f/40 shots I posted earlier, but this one was taken at f/25 instead. I just got around to processing the avi file.

Orion and Running Man

Posted By Tyler Allred
Hi all. I am bored so I decided to take all my Orion data and combine it into a single image. This was data from two different nights, combined into this image. It is a lot deeper than either of my earlier posts. Let me know what you think.
Cheers,

Phocylides, Nasmyth, and Wargentin

Posted By Tyler Allred
Hi all. I got in a few minutes of imaging last night between the clouds at about 1 AM. The high clouds were everywhere, so I couldn't do much, but I did manage a few moon vids. Here is the result of a stack of 600 frames (of 1400+), taken with my Celestron Ultima 2000 and Toucam Pro 840 using a 2.5X Powermate. It is an interesting area when the moon is nearly full.

Rosette from Utah

Posted By Tyler Allred
Hi all. I had clear skies last night, so like an idiot, I decided to try to image the Rosette. I don't let small issues like an almost full moon get in my way! :S At any rate, this image required lots of processing to get rid of the gradients, but it turned out OK I guess.
Cheers and Clear Skies!
Tyler

BTW - My autoguider wouldn't work last night, so this image was composited from 40x2 minute frames, unguided. 20 minutes each LRGB

Crab (M1) from Utah

Posted By Tyler Allred
Hello all. We had decent conditions again last night.... although the moon was pretty bright during the late hours. At any rate, I tried the crab for the first time ever, and it turned out OK. I used the Extender-Q on my Tak Sky90 to get a litle more image scale. I would like to try this with the 4X Powermate as well, but that will need to wait for another day. This is 25 minutes (5x5min) of Luminance data, which I used as G and B channels. Then I added 20 minutes of Red (4x5min) as a red channel. It turned out OK, I think. If I get more time I would like to add separate G and B channels to the data, but from what I have seen of the Crab, I don't think it would change the final image much. Questions and comments are always welcomed. I am in the learning process.
Cheers,
Tyler

Saturn from Utah

Posted By Tyler Allred
Here is another f/40 attempt at Saturn, using the Celestron Ultima 2000 (8") SCT and Toucam Pro 840. Seeing was maybe 6-7/10 and transparency was good. We had a split jetstream that gave Utah a break from the normal terrible seeing.
Cheers,

Pleiades - M45 from Utah

Posted By Tyler Allred
Hi all. I took this image last night under the light polluted skies of my home in Orem, Utah. It is my first attempt at the Pleiades. It could use more work but it is not bad for a start.

No Pleiades image that I have seen can compare to Jeff Hapeman's beautiful recent post of this object, which sets the standard IMHO.

Question? on Processing Subexposures

Posted By Tyler Allred
Can some of you more experienced people comment on when to "add" subexposures together versus when to "average", "sigma combine", etc. I am just not sure how to combine my subexposures for the best results. Thanks for any info or links.
Cheers,
Tyler

Whirlpool from Utah

Posted By Tyler Allred
Hi all. I got some clear skies last night and decided to try imaging with my Ultima 2000 8" SCT. I had some guiding problems and a host of other issues, but I ended up with a decent image of M51. Once I get my guiding issues worked out, I would like to try this again. Comments and suggestions are always welcome.
Cheers,
Tyler
