Thank you Robert. The sky is full of pleasant surprises and every night that we go out to see it or photograph it can be a special night if we are lucky.

 

One of the things I like most about this Forum is to be able to enjoy and share the pictures that other colleagues make of rare, unusual or simply beautiful objects. The EAA has the advantage that allows us to inspect more amount of sky in less time and many colleagues share their beautiful and interesting photos. Thanks to all also.

I particularly like the objects one million times farther away than the star appearing in the same image.

Full moon and all, I was out last night.  Suckered by the first clear night in a week or so!

 

Equipment/software:

  • Atlas EQ-G mount
  • Celestron Omni XLT 150 f/5 Newt (new favorite EAA scope?)
  • ZWO ASI224MC camera, no filters (pixel scale 1.0 arcsec per px)
  • SharpCap 3.2 (images captured "with adjustments" as viewed)
  • EQMOD mount control
  • Cartes du Ciel planetarium software
  • AstroTortilla plate solve
  • Photoshop (convert PNG to JPG, no crop, no adjustments)

I love the nice round stars I'm getting from this OTA.  With the small frame of the 224 sensor, I do not need a coma corrector.  I can see only a tiny amount of coma creeping into the very corners of the images, certainly not enough to warrant putting a CC on the scope with this camera.

 

SN 2018ivc in M77.  Stacked 186 frames @ 8s each = almost 25 minutes total.  Dark calibration included.  I was pleased at how clearly I was able to see the supernova at around 11 o'clock, just off the bright core.  North is up in the image.

 

m77-Stack_186frames_1488s.jpg

 

Comet 46P.  Stacked 15 frames @ 4s each = 1 minute total.  No dark calibration.

Thanks for looking.

I have a new toy, the ES/Bresser 8"f3.9 Newt. I'm surprised that it appears, even with the small chip of the LSX2, that I'm getting coma showing up. Unless it can be that I'm not as collimated as I should? 

 

Anyway, here are a few shots.

Good combination camera / telescope and good photos.
With the Ha filter you do not have oval stars on the edges .....

We're having a cold snap in southern Arizona, but I braved the low-30's temps (I know, I'm a wimp in the cold) for a few hours last night. All are 30sec subs, taken with my 14Edge and Hyperstar @F/2, ZWO1600 MC-C with IDAS P2 filter. SharpCap Pro 3.2 for live stacking with master flat and master dark.

NGC 3079 is a barred spiral galaxy about 50 million light-years away, and located in the constellation Ursa Major. A prominent feature of this galaxy is the "bubble" forming in the very center. The Supermassive black hole at the core has a mass of 2.4X10(6) solar masses, its a Seyfert type galaxy. On the right you can see another weaker galaxy (mg 14.78)

Very nice captures, ronpen. Did you note the total integration times, or gain setting?

 

I opened the box for my new ASI294MC Pro only yesterday. Still waiting for a clear night opportunity. If I see images like yours, I’ll be a very happy camper!

Thank you.  It's amazing what Sharpcap is capable of producing via live stacking, live processing...

 

Total integration time for each object was around the 20 minute mark but I was seeing a nice image way before that.  The objects actually appeared within the first few 10 second stacks. I was limited to 10 second stacks due to the mount.   Gain in Sharpcap was set at 300.  Cooling was set at -10.  No darks or flats were used.

Ultrastar mono with a 135mm f2.8 chinon lens, binning at 2, RGB as follows: h-alpha 5x30, sii 10x30, sii 10x30. All done in Starlight live, no post processing. Super steady skies tonight over Cincinnati! Very happy with the 35 degree temperature, too.
