Really excellent results John - well done:-) Your M27 looks about the same image scale as my M27 via 12'' @ f/3.6 and 1100mm fl - could you be working at f/6.3 rather than f/ 3.3?

Best Nytecam

The new CN3.0 must still be transitioning images, all of em are not showing up :-( 

 

However, I'm certain I have the 3.3 reducer in place and no cropping/zooming was done.  The LSx2 gets right up to it FR, I wonder if that is increasing the image scale that we are seeing?  This means that I'm not at f3.3, the closer I get to the FR?

John,

 

You absolutely are not working at .33x reduction if you're camera is closer than it used to be. The only way you'll get the full capability out of that focal reducer is if you have something in the area of 60mm spacing between the sensor and the lens elements in the focal reducer (I'm assuming that you are using the Meade f3.3 reducer ... if it's something else then the spacing number will be different).

M27 from last night...

C11+MCX+DS filter  - 17s capture.  No processing, no stacking, no histogram adjustment.

 

M27 C11 17s nostack

 

 

Wider field -- M27  with C80ED - MicroEX - 17s   also no processing whatsoever

 

M27 c80ed 17s

I recently purchased the Galaxy Contrast Enhancement Filter from DGM Optics: http://www.amazon.co...0?ie=UTF8&psc=1 It only filters out light pollution from 540-590nm. Pretty simple and made for galaxies which are sensitive to Ha and other filtering. It also works good on nebulae. Here is a screenshot of NGC6888 Crescent Nebula using Mallincam Xtreme/C11/CGEM DX.

 

Now look what happens when I take the same image and press Autocorrect in Fotor. https://www.flickr.c...ns/14666296358/

 

Fotor and a little contrast filtering seem to work quite well together.

Great observing session last night. Quick and easy, exposures between 5 sec to 45 sec. This time I know I'm operating faster since I have a wider fov. Need spacing worked out.

Some screen caps of the M27 Dumbbell Nebula I took tonight , only got about an hr or so between cloud coverings to look around .

   I also just updated my video render in my software to directshow

can't believe how much nice it renders videos ... much nicer then the older AVICAP .

Submission,

Nice shot!
I didn't quite understand. What software are you using and what did you change?
Is the upper image with the new software and the lower image with the old software?

Thanks,
--Dom

I programed the software myself ... both are from the same software ... I had DIS on in the camera , that's why the first image seems a little cropped.

DirectShow just uses better filters to convert the incoming signal and the filters can be adjusted with custom FilterGraphs , witch I don't have programmed yet .... another winter project :)

Stephans Quintet using Mallincam Xtreme, 220secs, Galaxy Contrast Enhancement (GCE) filter, C11, with lots of dew on the scope. Using maximum gamma on the Sony color corrector.

Great shot, Randy.  I'm glad to see someone else is interested in the Hickson Compact Groups.  My goal is to get all 100 of them.  Here's a link to what I have so far, including Stephan's taken with my Lodestar X2.  Next time out, you might want to try mono and see if you like it better.  It eliminates a lot of the noise and tends to show more detail.  Keep them coming!

Also, here's a link to a great reference on the Hicksons.  Most of the visual viewing is done with a 22" scope, so it shows you the power of EAA.  In some cases, he can only see the objects with averted imagination.  Download the atlas.  It very interesting and helpful.

Don, those are great. I would love to see how the new Sony A7S would fare using 1-3min exposures on the Hicksons.

First attempt at video photography using Nexstar 6SE /w LN300 camera and .5 focal reducer.

Ring Nebula - 3 frames, 17s,  processed with DeepSkyStacker.  Cropped pic to see nebula center.

You can make out the center star. I'm 10 miles from Denver, so not a dark site.

Here's one of the Iris Nebula using Mallincam Xtreme at 170s. AGC0 produced a smoother image than AGC4 I typically use. 

 

Here is a touchup using Fotor. https://www.flickr.c...ns/14961171508/

Last might while integrating on M27 (9/6/14, 9:33pm CST), I noticed a very faint trail at the bottom of the Nebula.  It looks way to thin to be a "regular" satallite trail.....what do you all think?

 

M27 with a friend.

Andy,  not only that,  it looks like M27 illuminated the trail.

Andy,

When you have written on a shot "Integrating: 3 of 55 sec, Frames 3 of 3", does that mean that you are stacking 3 exposures of 55 sec each?.

What does the 32 mean in "Integrating 32 of 51 sec, Frames 4 of 4"?

Thanks,
--Dom

Dom,
 

Yes, I am stacking.  I snapped the pic of the desktop to show the configuration of the scope.  Integrating 32 of 51 sec shows the progress of the in-progress integration, and it was adding the 4th of 4 frames to the stack.  With the Miloslick software, I simply used a rolling stack, so the stacked image was always being refreshed.

 

Andy

Dom what this means is that the 4th image is being captured and once completed the 1st captured image is dropped off and the 4th image is average into the total stack therefore still maintaining a stack of 3 only and not 4 if using the rolling technique.

 

Andy extremely nice images captured!! What was your AGC set to?

 

Chris
