 A full frame from the 80mmF4.8 and the ASI294..10 second exposures x55 (550seconds total) in ALT/AZ done in Sharpcap 3.1 to show stacking and alignment software.
From Tampa the other night..M11 area... 10 to 60 seconds exposures can be done in alt/az and stacked up to 1/2 hr with stacking software in sharpcap or also infinity software eazy/peazy "live imaging"...with 28mb files from the 294 stackin/alignment can takes up to 3 seconds.. I still have alot to learn about this new camera,,, Check out the full screen view, simple alt/az viewing 30lb total equipment weight...portable..lol auto align plop and go setup.(good for old guys) Let the new software do the work. I'm trying to keep it as simple as I can with just shapcap 3.1 and win10 photos software only. The TOTAL amount of my time spent on this simple image..including all stacking and image adjustments and converted to a small jpg to display here was less that 10 min!

 

BTW  did you notice that the core did NOT blow out! and there are so many weak stars showing also...This camera is slightly different and I think the 65k well depth might be why. But longer fainter objects will need to be done and Im not using astrotoaster to push this image just sharpcap data and win 10 viewer..very simple to do. No astrotoaster or photo shop.

Yesterday I tried the new ASI294 with my 60mm solar lunt. just for fun and this is a screen cap from my nsn broadcast..I still have alot to learn with this camera,but it did work.

Here is a single frame, I posted in another forum.  No processing, raw frame. 

ASI294pro @ -20C, AT65 (420mm FL), 30s exposure, not debayered.  Just converted from .FITS and resized for posting here.  This camera is very sensitve!   Note this was taken under almost full moon from Orange/Red skies.

These were done with ASI294  60 second ,  stacked,AT10INTT@F4 ,EQ8, This was B4 I learned about color balance...done in sharpcap and win 10 photos..

 

also focus is off some...dahh...and this is also B4 I learned how to align frames in sharpcap...so just stacked.

 

Downsized from 28mb png to less than 500kb jpg to display on CN...

 

THESE are ALL full Frames...and this is B4 I used the orion filter...that I think improves color....and learned more about color balance..

I think next time Ill do better "Live Imaging"

M8,,,its at the top and on photo if you click on it.

 

Al, with a orion imaging filter its 68 and 98...sometimes....

This might of been without...

 

But I start out with single frames..then look at hystrogram and adjust color balance (with exposure settings I use) then put it in auto....B4 I stack.

But color balance is up to each of us to like or dislike.  subjective..lol

 

 

If you don't change gain or exp much it will hold..

Ill try and find the data file..

Bob

And NGC891...same setup

 

Ill try and find the settings file on color balance.. BTW these are all a max of about 20-30 min total to display this way. (capture and adjustments) using Shapcap 3.1 and win 10 photos to convert.

They look almost the same after 4-5 stacks,but I'm testing shapcap stacking.....

 

PS look for the faint galaxy/neb

I also am having a tough time with color balance....on the 294 and don't think I did with the 1600....but it just might

be me and the learning curve.. when I change gain or exposure times sometimes. I don't think I had to work at it with the 1600 as much.

I am using win10 photos to help some for displaying..  I have over 9 GB of data on the 294 and its taking some time to sort out..and

a learning process for me. Right now I'm only using sharpcap to capture and stack..then photos to view.. Astrotoaster might be a good

choice also. But I'm trying to keep it as simple as I know how.

But its helped me to use a single frame and set the color balance manualy then put it to auto...most of the time.  Using the hystrogram (single fame)  I try to change gain/time to get a good curve on the left side  and move colors (R-B) on top of (G)

Then I stack... this seams to help me to be able to align frames during stacking..

you're off to a great start mega256 and it would be great to hear from the other users of this camera like Astrojedi, Al and Brandon what their thoughts are regarding the color. I am interested in either the 294 or 1600 but waiting to see more results from the 294. Thank you for sharing your work.

Great show, thanks for showing me what binning can do, very promising camera for EAA.

I'm looking forward to seeing how it does with larger aperture and DSOs. It might be comparable to A7s times with binning, we'll see.

Iv been looking at OSC cameras...both CCD and Cmos.....

Downloading files from the web...in user and manufacures  sites...Then streatching them in win10 photos...to look at STAR COLORs....

at many different sites... Iv allways liked the infinity/414ex for  star color..and now the asi294 with its big well depth..

most no matter how I streatch images (win 10 photos) I cant get a big variation's in star colors... some great pics but I'm looking  at star colors,,,, other than white (lol)

I am extreamly happy with the ASI294 ability to have star colors...I might be on to something or it just might be me? I just looked at the new  horizon pics also , and cant get

much color changes on stars...

I know this is being very picky...but I think we need the data to streatch the eaa image with what ever we use...(astrotoaster,infinity,win 10 photos,ect)

In this case I think the new 294 chip excels,,,

In EAA we normaly try to go as fast as we can to a displayed image...

 

Download some OSC images from the web site and open them in win10 photos,edit then streatch them for color stars..vary bright and color controls and look at the star colors as a test.? Look for many different color stars....

or is just me?   This M27 was the AT10intt@F4 ..chiefland..The M27  above post was from the AT80edtt@F4,8 (Tampa)..both have lots of star color.imho

Hi,

 

does anybody know, if the ASI 294 is compatible to windows 7?

 

best regards

Its not the 294  but its Sharpcap and your computer/speed....

 

http://www.sharpcap.co.uk/

 

But there is normal software like nebulosity  ect that should work also...

 

But my guess is that it should,,,but doing it  "live" with sharpcap and  live stacking  a cpu with some speed and usb3 will work better.

Hi Bob! Super shots again,

 

I tried to put my my ST-80mm on top of my ALT-AZ LX200 with no counterweights and in wind. I took a few shots from downtown Saint-Jean in very bad seeing conditions ( Transparency was good).

 

However!! I think the results I got where great.

 

All were taken between 350 and 400 gain and a are between 4sec-8sec-15sec per frames for integration time that is written in the title.

 

PS: Please note that I have little experience with achromatic refractors, but I like the results still. I have to read about those ''Triangle Stars'' probably pinched optics or what not from the holding rings that are super tight on the ST-80 and are really close to the lens.

Yeah!  I Have a filter but sadly it is the Orion Ultrablock which is great for nebula visually but kills everything else lol. I have to find a way to swap it for a Orion Skyglow or another filter. Again more spending lol. Yeah the star color are cool but the purple haze of doom of achromatic refractors is present. I don't mind because i'm really just doing observation but it does show alot on a F5 Achro.

Nice example of the high dynamic range of this camera.    Orion Nebula...  how to get the trapezium stars without blowing out the core and get a lot of the nebulosity also without combining different images with different exposure settings...  do it all in one exposure setting...

 

M42  5s  x 40   no darks.    Histogram tweak and conversion to .jpg for posting here.    C11 @ F6.4 ish + 1.25" Lumicon Deepsky filter - ASI294pro at -25 C cooling.

Eazy/Peazy---alt/az--HA-ASI294

 

AT80edt@F4.8 Evolution alt/az mount ASI294 bin2 gain 500+ HA- 48to60second  stacks of many all done it Sharpcap...great staking up to 1 HR total..Live NSN

IMHO  not bad for a color camera with  10nm HA filter..... Next time Ill try bin 1 for more resolution.
