  1. Well, although I'm not as experienced as all of you I too have a problem with the OIII vignetting and the respective flats. and as some of you know, I'm working with the Luis Campos monoMod monochrome and TEC cooled 450d camera. My 1st Bicolor image (HA + OIII) and my 1st Tricolor (HA + OIII + SII) images done a few days ago - M1 and the rosette - had issues with the vignetting shower on the OIII session. I've tried the flats underexposed, normal and ovewrexposed at 1/10s, 1/20s and 1/40s (Histogram lump lower, at level and higher) than the OIII lights lump. and on Pixinsight I was unable to remove the vignetting completely. I've done over 40 sessions with the monochrome and RGB cooled 450d cameras in HA and RGB and no vignetting issues. I did one session only with the SII and no vignetting. I did two sessions with the OIII...and vignetting. Something has to be wrong! cheers Paulo I talked to Luis Campos about my problem...and he complains of the same issue. I'm sure there is some issue with the Baader OIII. btw, I use the Gerd Newman Aurora Flats panel and Luis, I believe, uses an entirely diferent flats gear.
  2. Hi there, Luis had told e you were doing some attempts on the debayering ( I didn't dare do it since it's so damn difficult). Even the Central DS people have given up on the process after destroying inumerous sensors. as far as I know Luis only destroyed one sensor right in the beginning up to now, and he's already made about a dozen MonoMods. And their cooling mod is equally very complex due to Luis' refinement of the TEC cooling combined with the original (and secret) anti dew system. I go down to -5ºC and don't get any dew :-) I confess I'm very lazy and I'm very happy with the results I've obtaned in the past year with the B&W 450d...giving me the opportunity to stay clear of the more ellaborate CCD imaging without the LiveView function that the 450d offers me with Backyard EOS. best of luck with your attemps :-) cheers paulo
  3. Thanks Paddy for the tip I will follow it on my next processings...and I have a lot of them :-) cheers Paulo
  4. Paddy, I did use that combination as the main one, amongst others. Actually one of my examples is also a Bicolor process (no SII). I just got lost in the midst of all the "save as" and honestly I can't figure out wihich...hehehe. I also did the SCNR on green (not sure what you mean by "Ave", however). Can you clarify, please? The entire process was done following probably the best PI tutorial I've ever seen (and I have almost all of them, including Warren's and Harry's): the Light Vortex Astronomy one on the Rosette processing. Simply brilliant! cheers Paulo
  5. Mick, in fact the brightness is Ok on my laptop, but the truth is that the result varies quite a lot from screen to screen. That's why, a long time a ago, I decided not to process on my full HD laptop. The images looked damn pretty there but on the regular 1400x700 (and similar screen sized) laptops ithe result was Rubbish :-). This is just the 1st Tricolor I've ever done... we always get carried away with 1st attempts, experimenting on new techniques...hehe...I'm no exception. cheers paulo

    2nd & 3rd Imaging Years

    I'm starting now to publish my 1st photos of my 2nd imaging year, with a new setup and techique. This setup is totally different from my 1st year. On my 1st year I had fun - and fell in love with Deep space imaging - with a very fast system: C11 Edge HD + Hyperstar @F2. Out of about 70 photos on my 1st year - and for a rookie - I got half a dozen good ones, a few more so-so decent..and the rest quite weak. NOW IT'S YEAR TWO...AND I HOPE IT RUNS EVEN BETTER
  8. Hi there, This my 100th image since I started AP two years ago, and it's dedicated to my eldest son (30). The M1 has always been a very difficult target for me due to it's characteristics. I was able to nail it in H-Alpha about a year ago (in my 2nd album here on SGL) but I still wanted do do color on it. So on Dec 19 I went bicolor for the 1st time. I did 10x600s in Ha and 10x600s in OIII. I used the Baader line filters in my 450d Luis Campos monochromatic MonoMod and lowered the sensor to -2ºCelcius. I did 10 darks (not needed) 2o flats for each filter (OIII is more sensitive to brightness) and 50 Bias. I post produced in PixInsight and Photoshop CS6 Here is the result. I hope you enjoy it... and a Happy New Year to all Paulo Mesquita Sintra Portugal
  9. Hi all, before going any further...Merry Christmas and a Happy New Year. This is my 3rd M42 (second with the Luis Campos 450d MonoMod Canons. I've blendes H-Alpha with RGB, after going through a painful learning process with PI's HDR Composition, since both RGB and Ha images had to have HDR done with their different exposures to cover M42's huge Dynamic Range. So the method in short was: Ha + Ha RGB + RGB HaHDR + RGBHDR (PI's NBRGB script) SESSION PLACE & TIME: -Local: Sintra, Portugal -Date: 21.12.2014 IMAGING: CAMERA 1 - Luis Campos MonoMod Monochromatic Canon 450d: - modified with monochromatic & TEC Peltier cooled @ minus 15ºC from ambient temperature Lights - Astronomik H-ALPHA 12nm - 10x600s @ +2ºC Lights - Astronomik H-ALPHA 12nm - 3x20s @ +2ºC Flats - x 20 @ 1/5Tv Darks - x 10 (not necessary, but still did them) Bias - x 50 (not necessary, but still did them) CAMERA 2 - Luis Campos MonoMod RGB IR Modded Canon 450d: - modified with Baader IR filter & TEC Peltier cooled @ minus 15ºC from ambient temperature Lights - Hutech IDAS LPS V4 - 25x150s @ -2ºC Lights - Hutech IDAS LPS V4 - 10x5s @ -2ºC Flats - x 20 @ 1/200Tv Darks - x 10 (not necessary, but still did them) Bias - x 50 (not necessary, but still did them) SETUP: Telescope: Orion Optics CF 200/900mm F4.5 1/12 lambda newtonian Field Flattener: Baader MPCC MKIII Filters: Hutech IDAS LPS V4 clip filter ASTRONOMIK 12nm H-Alpha (36mm unmounted) Focuser: Orion Accufocus Motor kit Mount on pillar: Skywatcher AZ-EQ6 Pro Autoguiding: Orion SS AG kit - 9x50 short finder + SS AG CCD Flats: Gerd Newmann Aurora Flat Panel SOFTWARE ON LAPTOP: CAPTURE: Backyard EOS AUTOGUIDING: PHD GUIDING PRE PRODUCTION - PIXINSIGHT PRODUCTION - PIXINSIGHT POST PRODUCTION (very little) - PHOTOSHOP CS6
  10. no chance Michael! the reducer is just totlaly inadequate :-)... cheers paulo
  11. Thanks. The 450d is an exeptional camera once the bayer Matrix is scraped off! Luis has done it with 100% success and the results are starting to show :-)
  12. After some laziness...I processed another one in the oven...:-) It's my 1st attempt on Gamma Cygni, witha great little Borg (now in the UK) but with an inadequate reducer. Still...I almost got away with it :-) I'm posting the lone H-alpha and the combined H-alpha and RGB images.

  13. here is my 2nd H-alpha photo ever attempt, about a year ago with a Monomod and peltier cooled Luis Campos 450d @-15ºC from ambient temperature. this is the result of 8x600s lights with a 12nm astronomik filter on the monochromatic 450d. 20 flats, 50 bias and 8 (not needed) darks The scope is an Orion Optics CT8 on a SW (at the time) NEQ6 mount. I've been waiting for better weather (Portugal feels like England this Winter) to have a got at OIII with the mono cooled 450d and RGB with a baader IR modded...also TEC cooled 450d (yes, I have two cooled 450d's...one mono and one rgb) cheers paulo
  14. I don't know exactly what your issues have been with the SW AZ-EQ6 + Sky safari, but what I can say is that for such a good mount the HC and it'sd firmware is total Rubbish. Since day one (and i'm on my second HC right after purchase) the HC decides to go bezerk on me when it feels like it. It either points L/Years away from target when doing Star Align, (and I have a fixerd pilar...no Polar align done. Just switch on and go), or crashes when "moving to object", or even doens't stop the mout when it's at faster speeds from sidereal rate (whe we're aligning) and goes on and on until i need to swithc everything off and restart. I has been a nightmare sometimes. And I'm not complainging about the mount. It's the HC that is Rubbish.,..or it's firmware. Not sure which. cheers paulo Mesquita
