At my current rate I should reach dark energy status in approximately 102 years and 3 months... Game on....

All I'm going to say is.... FINALLY A MOONLESS CLEAR SKY PEOPLE....

On 7th August 2015 I setup the scope and started imaging the Cat's Paw nebula, when I checked on the system 30 minutes later I was DISSAPONTED to find that clouds rolled in... I waited for the clouds to clear but no luck... While I was waiting for the clouds to clear before packing up I decided to reprocess my M16 data that I captured across 7 nights in June and July. Here are the reprocessed images... I'm quite happy with these seeing that the data was captured through Baader Ha, SII and OIII filters on a full spectrum modded uncooled Canon 40D, nights are quite cool tho, about the 6 degree C mark so I guess that helped. I concentrated on lowering the amount of purple halos around stars and attempted to preserve maximum detail, the purple halos are still there but not as severe as in the first version. I still have a bit of noise/grain in these images, but when I ran the noise reduction filter I started to lose detail, and the level adjustment that the detail wasn't effected too much the amount of noise reduction was not worth changing. I think this was the best balance between noise and detail.© Mariusz Goralski

As luck would have it... I setup, start imaging and 35 minutes in the CLOUDS ROLL IN!!! At least I got some subs I guess..

I think I know how the Peach does his planetary images... all I need now is Jupiter to come back to prove or disprove my theory...

Once again I was lucky enough to have very clear skies. I was observing Saturn through my 8SE and I kept on pushing the magnification to beyond the 450X mark and beyond with perfect views. With the 5mm eyepiece and the TV 11mm type 6 + 2.5X powermate the view was amazing... crisp and detailed. I thought I'd be stupid and put the 5mm and a 2X barlow to see what will happen, and even though the image was quite soft, Saturn was MASSIVE... of course that was 810X... but to my surprise I was still able to make out a brightish cloud band and the cassini division. With such a steady atmosphere I had to try to image it and I think these Saturn images are the cleanest I captured so far, so I thought I'd share. Work flow was I imaged the F20 pic through a Celestron 2X Barlow and the Skyris 618C CCD, and the F50 image was captured using the DMK 21au618 and a 5X powermate. The mono F50 image was used as luminance on the color data scaled up which was captured with the Skyris. I'm very surprised at the quality of planets I'm getting with the Skyris for a OSC camera. Image processing was done done in PS, Stacking in Autostakkert and a very small amount of wavelets applied in registax 6. I suspect I'm pushing my 8" SCT to the limit, or close to it, but if anyone has any advise or tips on how to squeeze out and more detail, please share. One feature I was chasing for over a year now was the Encke gap, I feel like I'm right on the verge of capturing it but perhaps my mirror is just slightly too small for it. -

Imaged F10 on a 8" SCT. OIII and the SII data was very dim and I had to push it more to bring out some nebulosity in that spectrum increasing the noise... Hence the purple halos on the NB image. I'll reprocess the narrowband image and attempt to remove the purple by tightening stars in the SII and OIII channels. Image tech specs.... H-alpha: ISO400 7 x 1800s Subs 7 x 900s Subs SII: ISO800 12 x 1800s subs 4 x 2700s subs 5 x 2160s subs OIII: ISO640 4 x 1800s subs 6 x 2100s subs 5 x 1500s subs RGB: ISO400 9 x 630s subs 7 x 350s subs 10 x 150s subs Data captured across 7 nights in June and July 2015.© Mariusz Goralski

WHAT? A second clear night in a row!!?? This never happened before... Except for the other time. I think it's time for a lottery ticket?
-
WOO HOO!!! Finally a totally cloudless night... And the project continues!!!! Ha done, SII done... OIII pending...
-
For a week in a row... blue skies all day but cloudy at night?

I have a solar max and solar filters BUT.... BUT... I know how the astro tease works, the moment I setup my solar scope the clouds will get curious and come around to "see what I am doing" ha ha ha... I don't want to pull my 8" apart to setup for solar viewing yet since I'm in the middle of a "pillars of creation " narrowband imaging project and have my guider and camera setup and calibrated for quick continuation of imaging... once the clouds clear out...

This image is a reprocess and a stack of only the best of the subs. Used used mostly 6 x 5 minute and 2 x 10 min subs through a Baader Moon & Skyglow (Neodymium) filter at F10, a total of 50 minutes of useful subs taken with a modded Canon 40D @ ISO200.
