  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. 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).

  4. Last night I set everything up ready and expecting a full nights imaging. Unfortunately the weather gods intervened and in the end limited my testing to just 30mins of which I managed to gather 12mins of good data...! The weather conditions were horrible, intermittent clouds with the thin wispy stuff in between etc... Normally I wouldn't have set everything up but it was promising to be clear??? In the end it ever happend. So here is the first successful test at F10 with the new Mewlon (with corrector baffle assembly) I still have some minor guiding issues but I'm very pleased with the results above; the stars are greatly improved with no sign of coma at all. The coma was never that bad but it was noticeable at the corners even on the ST10 chip. I would say that these stars are as perfect as they can be, give the weather conditions. I now have a telescope that I can guide at 2500mm fl, 3000mm fl was impossible!!! Or too frustrating? It can image the smaller DSO with no coma and hence has become most versatile. (Not just a specialised planetary scope). The next test will be M1 the crab at F7 with the new reducer fitted, most probably after I return from my net business trip.
