Jupiter in very good seeing: 10-17-2012
      #5474540 - 10/17/12 06:54 AM Attachment (123 downloads)

We had very good conditions this morning although I had to keep adjusting my collection settings due to moving banks of water vapor and thin clouds. I managed to get four RGB sets w/ IR685, and 25 OSC images w/ the DBK21AU618. Some of the data looks pretty amazing for our area, here is an example of one of the OSC shots taken at 07-50-33 UT. I won't get to process the mono cam take until after work today and will have to post anything cool later.

Clear Skies,
Brian

Very very nice. I was up in NJ doing the same thing. It was a good night for imaging

I think this is your best image to date Brian! I was out there with you about 60 miles to the north in Baltimore and fully share in your concern about the moving banks of water vapor and thin clouds, heck the humidity was up there at 87%! I was just glad that the temps didn't fall another 4 degrees to the point where they matched the dew point, we had enough to deal with in keeping pace with the rapidly changing transparency issues. I'm just now processing my SER files from around 2:30 AM, lots of fun; looking forward to your monochrome cam data later on today!

Love the detail you captured in the moons. Is that Ganymede? Fantastic imagery

Nice work, Brian!

I debated getting up this morning, but the debate got pretty testy and almost came to blows, so I stayed in bed just to be safe. I can't imagine what would have happened if I was actually debating with another person.

Wayne

p.s. what really happened was that I stayed up to watch the end of the ball game after watching the "debate" and had an early meeting this morning. I'm keeping my fingers crossed that we get another chance soon!

Nice work, Brian. I'm really surprised you got clear skies. I saw clouds coming in last night, so decided not to get up, and the satellite images I saw this morning seemed to confirm that we were socked in until dawn. You are smarter than a satellite!

Thanks Darryl...I'm working the RGB data now. I am having the hardest time trying to get rid of violet tones in the zone areas, I might go ahead and post one for discussion.

Clear Skies,
Brian

Thanks everyone for your very kind comments, glad I decided to have a go instead of staying in bed The seeing turned out to be far better than expected and I knew I was in for a great ride when Jupiter popped up on the screen. Just happy to have been in the right place at the right time…
Pete – very challenging (and strange!) atmospheric conditions …you know what I mean
Steve – the moons are Callisto (top) and Ganymede (bottom)
Wayne – I stayed up for the debate/scrum as well, but caught a nap afterwards…it was still tough to drag myself outside
Kevin – I made notes on the weather conditions and WILL be looking for them in the future, even if things don’t look too promising…I hate missing good imaging opportunities

Clear Skies,
Brian

Thanks S.C., Trevor, and Glenn; it's nice to have a run of good seeing after the almost six month dry spell the first half of the year. On another note, Trevor and some of the other folks here really demonstrated the value of the IR filters, particularly at 685nm. I just got one and the 17th was my first opportunity to try it out. Here is one of the IR images I took that morning, all of my RGBs (which I am struggling with a bit, sorry for the delay) are combined with this IR filter. Back to the processing, I still owe some ya'll some images...

Clear Skies,
Brian

Sorry it took me so long to get back with an RGB-IR image (RGB-IR1 from 10-17-2012 07-30-00 UT), I have been struggling with the processing. I cannot seem to do anything about the violet shade, and I think the only way to capture the satellite detail from my first image is to process the moons separately...maybe a bit later. I am open to suggestions and critiques, still being relatively new to the mono cam and filter game I appreciate any kind of constructive feed back. Thanks!

Clear Skies,
Brian

Thanks James, moxican, Frank, and John! Still trying to figure out the violet tone thing, nobody has chimed in on that. One thing I noticed trying different processing routines with RGB and RGB-IR stacks - the color is much subdued when I don't use the IR image, but the detail really drops off, not a good trade off in my book...

Clear Skies,
Brian

Brian, in the matter of the violet shade if you use Astra Image to combine the R, G, and B TIFF files you can select 80% or 90% intensity for the B channel to balance the colors a little better. What advantages do you find for the IR685 pass filter over an IR742? I have the latter and am considering buying the former. Nice RGB image with the monochrome cam!

Pete

Hi Pete. I think the jury is out on the cost/benefits of the 685nm filter at this point, I need more time to work with it and do direct imaging comparisons...so more on that later. I did manage to mitigate the violet tones a bit in processing by manipulating the intensity of different channels, and the moons look ok. I think I'll let it ride with this image for now...

Clear Skies,
Brian

I have the 742 and 685 - the 685 is a LOT brighter and has about the same attenuation of seeing issues. I don't know that I'd make a special point of buying the 685 if you like the 742 but if you have neither, I'd buy the 685.

Beautiful images, Brian.

Thanks Paul! I agree that the main benefit seems to be the brighter image which is no small thing if you are not shooting with a C14. For instance, folks using C8/C925 class OTAs in particular might want to consider the 685nm filter...

Clear Skies,
Brian
