Last weekend I got the chance to do some little EAA showing friends a bit of the skies - as there was already an almost full moon and from within a city balcony I used the IDAS NB1 dual narrow band filter together with my little Photoline 60/360 APO  (with flattener). Mount was AZEQ5 in EQ mode with guiding (PHD2, Zwo guiding scope with ASI178mc as guiding camera) Camera was the ASI183mc Pro (cooled to -10C) with darks, single frames with 30s taken by SharpCap. Histogram tweaked within SharpCap. Gain was 111.

 

Here the jpg converted and cropped pictures of the final stacks:

 

* M52 and Bubble Nebula at 45 frames leading to 1350s total integration time:

Same setting as above, that is: Photoline 60/360 APO  (with flattener). Camera was the ASI183mc Pro (cooled to -10C) at gain 111 with darks, single frames with 30s taken by SharpCap. Histogram tweaked within SharpCap. IDAS NB1 dual narrow band filter... Jpg converted, not cropped.

 

* M31 and friends (I know, small band for galaxies... anyway!) with 36 frames leading to 1080s total integration time.

eventually I did replace the dual narrow band by an IR-UV cut and took some minutes of M27. Photoline 60/360 APO  (with flattener). Camera was the ASI183mc Pro (cooled to -10C) with darks, single frames with 30s taken by SharpCap. Histogram tweaked within SharpCap. JPG converted and cropped.

 

* M27, 23 frames leading to 690s total integration:

Geostationary satellites drifting by M11

https://www.youtube....eature=youtu.be

 

 

I was going to live stack M11 when I noticed a couple geostationary satellites slowly streaking by.  Instead of live stacking, I captured the sequence of 8 second exposures, and then animated it into a video using ImageJ and Blender. It is played back at 4FPS so it is a 32X timelapse

 

I checked Stellarium and it turns out the bright one is "DirecTV 15"

 

https://www.youtube....h?v=sz-d-T2FASs

http://spaceflight10...aft/directv-15/

 

It's a bigger than I thought it would be.

Fun tip with a Dob. If you point at a geostationary satellite it is stationary in the eyepiece, and it drifts through the star fields. Very zen.

 

 

Equipment:

Meade Mini LightBridge 114mm f4 Newt

RisingCam IMX290 mono CMOS Camera (8s at 1/2 gain)

OnStep Converted Super Polaris GEM

SharpCap 3.2

I'm going to try this!

If you were able to point at a geosynchronous satellite, it would trace out an analemma over 24 hours.

Saturday night, I went to a public start party with very nice bortle 4 skies.  I brought my EAA setup and showed people many summer nebula in color. We all had a great time.

 

I was using a Meade Mini lightbridge 114mm F4 Newt with RisingCam IMX224 on a Vixen super Polaris with OnStep.

I got there early but I had some mechanical mount problems that delayed my start. I took fresh dark frames and  a fresh flat frame using an EL panel.  The flat frames have significantly improved my images due to the undersized secondary of the  114. 

 

 

All pictures have been resized or cropped

 

M27 Gain3000 8s x 61frames 488s (Cropped)

gallery_280529_10253_70286.jpg

The dumbbell is a great crowd pleaser with the color cam

 

 

East Veil Gain3000 8s x 74frames = 592s

gallery_280529_10253_113812.jpg

People were very excited to see the aftermath of a super nova, the colors are an added bonus. 

 

 

M8 Gain3000 8s x 41frames = 328s

gallery_280529_10253_26017.jpg

teh lagoon was fantactic, it looks so deep, with all the swirls of glowing gas, and globs of dark dust. It was great for explaining the life cycle of  star clusters. 

 

 

M20 Gain3000 8s x 66frames = 528s

gallery_280529_10253_53374.jpg

The Triffid is my favorite color nebula, such a sweet color juxtaposition of emission vs reflection nebula. Another great talking point.

 

Ngc7331 Gain3000 8s x 62frames = 496s (Cropped)

gallery_280529_10253_5967.jpg

NGC7331 was a great object to discus distance. it is 47Mly away, buth the galaxies in the background are 310-420Mly away.  Thats from the Devonian to the Carboniferous period, Pangaea was just coming together.

 

M15 Gain3000 4s x64frames = 256s (Cropped)

gallery_280529_10253_6298.jpg

Wanted to round out the tour with some clusters

 

Pelican HH Gain3000 8s x 185frames = 1480s

gallery_280529_10253_78859.jpg

After the "official" end of the star party I wanted to try hunting down my white whale. I'm dead set on seeing the Herbig-Haro object at the tip of the long dust wisp in the Pelican nebula. I didn't get it this time , but  I'll try again with my filtered mono cam at finer "/px.

 

I had a blast, can't wait to get out there again.

Got a chance to get out last night for a little experimentation. I'm using my Celestron Edge 11, CGX Mount, and for these shots an ASI294 Pro Color in the latest SharpCap. The skies were dark but a little hazy. I've read elsewhere on Cloudy Nights that the IMX294 chip is tough to get properly calibrated darks, and for the first few times I tried to get some good darks a few months ago, I had to agree. But last night I was able to get them pretty nicely calibrated. These are the only shots I got after figuring them out. These are at 25 seconds, 12-15 frames, except the Dumbbell, which was at 16 seconds. I'm a little surprised that the differential in exposure duration still worked for the Dumbbell, but these are three of the better captures of these objects I've ever gotten. Did the dark work for the Dumbbell because the exposure was shorter?

 

They're all saved as seen, but cropped for the frame-alignment borders.

NGC 7365 Bubble Nebula Stack_113frames_1130s   so 10 second subs

 

SharpCap Pro Software

Orange Tube 8in SCT with a .63 focal reducer and an AVX mount unguided.

 

This was my main target for Saturday night on 8-24-19, I have a few more objects that I saved, but I was really happy to be able to see the bubble details. I need contaminate this new OTA to get rounder stars.    But whats interesting is I don't notice the lack of roundness when I am watching live as I am more interested in seeing the details of the object I am looking at.    Also I spent about 18 minutes with this stack as I was struggling to get the histograms right to see the details.   But it was way more than a gray fuzzy.
