Nice work on the black hole observations! All you need now is a gamma ray telescope like Galex. A long time ago, I researched a black hole in an edge-on galaxy (sdss 587741534395170893, http://cas.sdss.org/...dec=30.07921302). This image shows the galaxy and its black hole on the leftside. Space matter from a nearby dwarf is being pulled upwards through the galactic plane as shown by the arrows. The upper right hand image is Galex and shows the gamma ray plume. It looks like a mushroom cloud above the galactic plane.

Like the fact that you are pushing the boundaries with a ST80 & Mallincam AGm. Now only if we could see that black hole.  :)

Here are a couple of stacked images using a 60sec exposure value instead of 10sec .  The ASI224 camera image held up well for 60sec but I found that the background had more stars that had no color for the brighter ones and yellow for the rest.  Dark frame mismatch showed up much quicker as the temperature changed.  I kind of like the shorter exposures with more stacks although the work flow is better with longer exposures and AstroToaster is happier.  Sky conditions were not near as good as the previous night's and I was using the Idas LPS filter due to the longer exposures. Same C8@f3.

Nice images Andy! I particularly like M16.

 

Stacking brigs out nice detail. What program are you using? Is stacking done from a movie file or in software, while you are watching at the telescope?

 

Clear Skies!

Dom, I captured 15 single images, and did an average stack in DSS.  I stacked after the broadcast, I don't enjoy the AstroToaster while broadcasting, I want the objects to be the "star" of the show, not the equipment behind it.

Sadr Nebula with SX-825m and LodestarLive

 

Sadr.Nebula.Complex_2015.8.18_00.52.53_75%.jpg

This image file is 50% reuced in size and resolution. Please see the full size, full resolution image here http://stargazerslou...3893_723007.jpg.

 

This is the central axial part of the huge Sadr (Gamma Cygni) nebulosity complex.

The Faberge Egg at the bottom left is the often photographed Crescent Nebula.

 

1x60sec red H-alpha + 1x60sec all-spectrum luminosity frames live (men) stacked together in LodesterLive.

Captured with a Samyang 135mm FL f2.0 lense from Umtanum Ridge in the Eastern Cascade Mountains (120 miles from Seattle).

 

I chose this very pale color saturation as this seem to show the most fine detail, while still separating the nebulosity and star layers.

 

This capture was motivated by JimT's post http://www.cloudynig...iews/?p=6726733 mentioning that this object was one of his summer time favorites.

 

For comments or questions regarding this image please use the discussion thread http://www.cloudynig...iews/?p=6726733 . So that we can keep this gallery thread mostly for images.

Rose of the North with Elephant's Trunk (IC1396) using SX-825 mono and LodestarLive

1x90sec red H-alpha + 1x90sec all-spectrum luminance frames live mean stacked together in LodestarLive.

Samyang 135mm FL f2.0 lens with 7nm Baader H-alpha filter. Captured from Umtanum Ridge, WA.

The bright star on the upper right is Barnard's Garnet Star.

 

Apart from its higher, almost HD resolution, one of the main benefits of the SX-825/Ultrastar cameras is their anti-blooming feature.

This makes it possible to keep stars as tight pinpoint dots that are not overshadowing the subtle nebulas.

A touch of the natural pinkish color of the H-alpha radiation helps to separate the nebula from the star layer.

 

Very pale color saturation was chosen as this seems to show the most fine detail and matches the fluffy cloud like nature of the nebula.

About two weeks ago I posted a black and white image of the Elephant's Trunk just by itself, taken by the same camera but with a 300mm FL lens.

For comparison, it can be seen here in full resolution http://stargazerslou...9_3893_6263.jpg.

Sagittarius Star Cloud with SX-825m camera and LodestarLive

 

Sagittarius.Star.Cloud.M24_2015.8.17_23.21.08_75%.jpg

The image file is 50% reduced in size and resolution. please see the full-size, full resolution capture here http://stargazerslou...3893_569868.jpg.

 

To me personally, the tight pinpoint stars made possible by the anti-blooming circuitry built in to this camera are probably a more important feature, than its larger field or higher resolution (than those of the ICX829 based cameras). This brings entirely new classes of objects into the reach of real-time EAA. Earlier I have seen star fields captured only with DSLR's or dedicated astrophotography cameras.

 

The above image is a stack of two 30 sec frames stacked together in LodestarLive. One taken with a H-alpha filter and the other a simple luminance. H-alpha filter is not normally needed or used for star fields. But I also wanted the faint nebulas, that happened to be included in the wide field, to show.

The main objects on this image are the following. 

Emission nebula IC4701 on top,

Small Sagittarius Star Cloud M24 taking of most of the field,
Bok modules Barnard 92 & 93 imbedded in star cloud,
Emission nebula IC1283-84 (Sh2-37) the round object on lower left.

 

I would also like to point out that taking this image was also an extreme stress test of the stacking algorithm Paul Shears has built into LodestarLive and progressively refined. It is extremely difficult to stack the tiny stars with the accuracy required, when even a single pixel shift between the frames would show up. Fuzzy nebulae and larger blob stars are much more forgiving. Not mentioning that there are thousands of stars on the images that all need to be placed accurately on top of their earlier copies. All-in-all, the stacking algorithm passed the test with flying colors. We are grateful to Paul for all his efforts that he put into it to reach this degree of sophistication and accuracy.

Color with Mono Cameras and LodestarLive

 

I have had the pleasure to beta test the new multi-spectral feature that Paul Shears is building into LodestarLive.

Here is the preview thread by Paul  http://stargazerslou...ectrum-preview/.

 

Here are two images made with monochrome cameras and the current test build of LL.

First is the Dumbbell Nebula M27 from yesterday night taken with a Lodestar x2 monochrome camera.

Dumbbell.M27_LS.Ha+Oiii_2015.8.23_22.48.01.jpg

 

The second one was taken a couple of nights ago with the SX-825 mono. This is a 75% crop of the original capture.

Dumbbell.M27_Ha+Oiii_2015.8.20_00.01.32_crop75%.jpg

 

Both images are 5x30sec mean stacks.

The first three frames were captured with an O-III filter and assigned to the green and blue channels. Then two more H-alpha frames added to the stack assigned to the red channel. The minimum would be two frames stacked, one O-III and one H-alpha. I stack more because I like the resulting nice smooth texture. Exposure times are the same as would be with the same filters without the multispectral feature.

 

Please note that since we are using monochrome cameras, exposure times are shorter than would be with color cameras for two reasons. First, we don't lose light in the micro-filters on the pixels of the color sensor. Second because all pixels of the mono sensor are detecting the light equally. In case of a mono sensor only the yellow and magenta pixels are sensitive to H-alpha light and only the cyan and green pixels to O-III. (Right now Seattle is engulfed in the smoke of the massive forest fires further East. At the time the image was taken yesterday nigh, only the three main stars of the Summer triangle were visible with bare eyes on the entire sky. At 11:15pm even those were gone and I had to call off astronomy for the night. Moisture condenses on the smoke particles as seeds and the whole sky becomes uniform opaque white illuminated by the moon. Due to the smoke, exposure times were probably the double of what they would be under normal conditions.)

 

An added benefit is that narrowband imaging is not affected by light pollution or moon glare. The moon was up and past first quarter yesterday night. This new feature of LodestarLive makes it possible to produce genuine multi-color images with NB filters.

 

As far as I know, this multi-spectral, multi-color capability is an absolute first ever in real-live camera assisted amateur astronomy. We are grateful to Paul Shears for his continued efforts to lead the way and make this and other new capabilities available for the entire EAA community.

Western Veil in "Swedish" Palette with SX-825 mono and LodestarLive

 

W.Veil_Ha+Oiii_2015.8.22_00.32.55_95%.jpg

Please click on the image to see it in full resolution. It makes a difference in the detail visible.

 

H-alpha is yellow and O-III is blue in the "Swedish" false color palette.

Use of false colors is common in narrowband imaging. The best known is the Hubble palette but I prefer the Swedish for Ha+O-III.

3x120sec H-alpha + 3x120sec O-III frames live mean stacked using LodestarLive's multispectral capability.

Meade 10" SCT at f4.0 and Baader 7nm and 8.5nm H-alpha and O-III filters and in "Swedish" palette colors.

The exposure times needed were excessive due to the thickening forest fire smoke through which it was taken.

Normally I would use 60sec exposures for this object at f4.
