This is what the Helix really looks like:

Well done! I was referring to helix through a long focal length scope

I went out last night, June 8/9. The sky was clear, some dew came in the last 1/2 hour or so of imaging, no wind, transparency was very good, seeing was a bit mushy. I was trying out my new Orion 120ST telescope. It did very well on DSO's and the Moon. Noticeable CA on the moon, but absolutely none in DSO images, however, some bright stars showed the classic CA halo on brighter stars.

Hey EAAers,

 

It has been a long season without getting out there. We had fires in California last fall, then many months of rain. Now, even when those things aren't happening, it's still cloudy! I can't catch a break. Add to all that house hunting and ultimately buying a home, I just haven't been out there. Anyway, I got to capture one of my favorite galaxies, M106

 

EQUIPMENT:

Orion EON 120 ED Doublet

CEM60

ASI290 Cool cooled to -15c

No darks or flats subtracted. 

 

5s subs x 61 frames for 305s total (350 gain)

Stack 61frames 305s WithDisplayStretch

Here's a quick capture of NGC 3718 while the moon was lurking and the clouds were soon to cover everything.

The coolest thing about this galaxy is the group of galaxies at the top of the frame which are nearly 400 Million light years away!

I did a comparison last night on M57 with various filters to see how they helped or hindered with getting images from my light polluted skies (red zone).  I have posted on Astrobin with all the particulars.

 

The equipment used was;

Orion’s 120ST refractor

Atik Infinity camera

Various Filters (listed in photos on Astrobin)

Each capture was with 5 second subs stacked 30 times in Infinity software for a total of 150 Seconds.

I don't want to jinx it, but it appears summer is working well for me. 

 

I captured two very different DSOs - one little dim galaxy and one nebula in spectacular monochrome.

 

Orion EON 120 ED @ f/6 (with Orion reducer)

CEM60

ASI290-cool

 

First up the IRIS nebula (NGC 7023)

Stack 111frames 555s WithDisplayStretch

5s x 111 = 555s total

 

Next is NGC 3953. It is a barred spiral, where the bar looks like a little TIE-fighter flying in front of the spiral. 

Stack 150frames 750s WithDisplayStretch
5s x 150 = 750s total

Got out last night, but it was worth it despite some setup problems.  Always something... :)

 

But here it goes...

Finally got a chance to try out my 2x Powermate on the 8" EdgeHD. I didn't think it would turn out very well on a DSO but the Ring Nebula gave me a pleasant surprise! Much finer detail than I expected from a 15 minute stack at f/20 and 4000mm.

Had a very clear night this week and managed to get in a few captures.

I have posted links below to my Astrobin account so you can take a look.

All these were through Orion's 120ST Refractor

Taken with Atik's Infinity Camera.

All were 5 seconds stacked 30 times with Infinity Software.

The Optolong L-eNhancer NB filter for a OSC camera looks promising for EAA.  

 

This is just 4x120" stacked using SharpCap Pro on a C11" EdgeHD with a hyperstar lens and a ZWO ASI294 MC Pro camera.   Bortle 5 skies with poor transparency but average seeing   Camera was cooled to -10C.

Well, I had good weather for some stargazing last night. Transparency was average along with the seeing. Got bitten quite enough from the skeeters. The dew dropped and made everything wet, but not my refractor lens. My mount goto was dead nuts on both sides of the meridian, which is a rare thing for me. My equipment is as follows:

 

Orion 120ST F/5, working at F/3.15

Meade F/6.3 Reducer Corrector

ASI294MC camera with 2" UHC and 2" UV/IR blocker

Sharpcap 3.2 Pro on my Toshiba laptop

 

Any processing was done on the fly including: Unsharp Masking, Bilateral Noise reduction, Black and Mid level histogram sliders, a minor up tweak in color saturation and brightness.

All capture details are posted at the top of each pic, per the rules of this thread and forum!

My third night in a row for fairly decent skies for DSO EAA Imaging. This is getting monotonous...LOL. This time out, I chose my newly acquired 1991 Meade 2080 8" SCT, using a Meade F/6.3 reducer corrector and iOptron ZEQ25 mount (Incredible goto's) and my ASI294MC camera coupled with a 2" UHC filter and 2" UV/IR block filter.

 

All processing was done on the fly including, Sigma clipping, Unsharp Masking, Bilateral noise reduction, Logarithmic Horizontal Positioning histogram, using Black and Mid level sliders, color saturation and brightness control. All imaging details included in this posting.

 

The first two objects are Young Stellar Objects (YSO's). I found some interesting sites that listed these as possible targets for DSO hunting and I found at least two and the others are situated for the Fall skies. Because of their faint magnitudes, I had to push the gain up and the exposure time too, but this resulted in far more grainy acquisition.

 

In some objects, being about 10-15 degrees above the horizon, I had more atmospheric extinction to deal with, making the objects about a magnitude fainter.

Here are some new (to me) Planetary nebula found in Sagittarius, literally quite small (6" to 12" arc seconds in diameter):
