  1. Hi All, After a 8 month break due to moving I finally had a chance to do some simple Deep Space imaging. This image is of the Tarantula Nebula in the Large Megallenic Cloud (NCG2070). This is imaged using my modded Canon 40D at F10 2032mm using a Nexstar 8SE on a CGEM mount. The image consists of 12 x 5 min subs, 5 x 10 min subs and 10 x 1 min subs, all in RGB through a IR Cut filter. Currently I'm working on using the PEC feature on the CGEM, and after I've spent a few hours before trying to work out how it works... when it got to past midnight, I was ready to call it a night but decided to frame up on the Tarantula and give it a go... I thought it's not to shabby for a quickie, so I'm sharing it. As far as PEC goes, next time I get to do some astro, I should have NexRemote, PECTools and PHD to give me a average PEC training from 10 cycles... hopefully it'll improve the guiding accuracy and hence detail in my 2000mm imaging close up images. Thank for looking, Mariusz
  2. From the album: Deep Sky Imaging

    This is a 10 hour exposure of the NGC1055 galaxy using a standard Canon DSLR. The image is taken with a Celestron 8" SCT at F10 (2032mm focal length). The image consists of mostly 600s subs and approximately 2 hours of 90-150s subs, all at ISO 800. This galaxy is located at about 60 Million Light years distance from us, and at a magnitude of 12.5 is quite a faint object to image, especially when there is a little bit of light pollution with in the par of the sky it is imaged at... Looking at the result, I probably should have used the f6.3 FR to have less over sampling and most likely capturing more light in the same amount of time, or same amount in less time... end result most probably, at worst, would have been the same if not very similar and at best there might have been a bit more detail captured since guiding at 63% of the focal length and not oversamplig the subs would not be as susceptible to seeing/star fluctuations/movement.
  3. From the album: Deep Sky Imaging

    This is a RGB image of the Tarantula Nebula taken with a 8" SCT at 2000mm. 12 x 5 mins Subs 5 x 10 mins subs 10 x 1 min subs all at ISO800
  4. Hi All, When I was waiting for the Tarantula to get into imaging position to grab som Ha and OIII subs to add to the posted image, I decided to do some unguided subs of 47Tuc glob... its only 15 x 60sec, 15 x 30sec and 15 x 10sec subs in ISO800 at F10 using a modded Canon 40D. Seeing wasn't the best but surprisingly the stars were round for being unguided. Thanks for looking, Mariusz

    Dumbell Nebula - M27

    From the album: Deep Sky Imaging

    The Dumbell Nebula - M27 This image is a composite of a RGB exposure and 50% HAlpha mixed into the red channel and 50% of OIII mixed into the green and blue channels. Imaged September/October 2015 on a Celestron Nextstar 8SE, CGEM mount, modded Canon 40D at f10 (2032mm).
