  1. I'm thinking about Seagull nebula and bubble widefield.. waiting for Milky way. But weather this year is terrible!
  2. Hello Tom. H-alpha channel was shoot in La Palma with different scope and OIII shoot recently in Seaford area where I usually have sessions with less polluted sky. I've had difficulties with stacking (manually) as frames were in different angles and different focal lengths. OIII frame stacked:
  3. During recent night I've managed to take only 50 minutes of OIII in narrowband so I could add to previously gathered Hydrogen. This is more like experiment as it is my first bicolor image. Scope: Skywatcher Evostar 80ED DS-Pro with flattener Mount: NEQ6-Pro Camera: QHY168C Filter Baader 7nm H-alpha , Baader O-III CCD Guiding camera: ZWO ASI120MC Guiding scope: finderscope 16x300s exposure at -10°C (80 min total) in H-Alpha 10x300s exposure at -10°C (50 min total) in OIII
  4. Yes, too late.. I'm planning to change the scope maybe next year..
  5. I've just observed reflections pointing the telescope on the bright stars and slightly changing the framing. The beam bounces from the filter, then again on the concaved side of the flattener goes back to the sensor. The "bubble" is slightly smaller than the diameter of the lens in flattener.. Very annoying and I'm just thinking how to remove it. I will try next time without L-PRO filter but I don't have UV filter in my camera..
  6. Thank you guys, the bubble is the internal reflection between the filter and the flattener. Actually the anti-reflection coating on SW field flattener is poor. I'm thinking how to change the arrangements through the light path, maybe placing the filter before the flattener will help?
  7. Thanks guys.. I will try to get more frames..
  8. King of the winter night sky -Orion NebulaAs the part of our galaxy lies around 1340 light years from us and is the closest region of massive star formation to Earth.Only 27 frames as the clouds were covering all sky as soon as I arrived.. Scope: Skywatcher EVOSTAR 80ED DS-ProMount: AZ EQ6-GT Camera: QHY168C Filter Optolong L-PRO MAX Luminosity Guiding camera: ZWO ASI120MC Guiding scope: SW 9x50 finderscope 27x300s exposure at -10°C (135min total) 2h 15min binning 1x1 20xdarks 30xbias 20x flats
  9. Thank you Martin. I was experimenting with colors on the orange version trying to get similar as on Hubble website. I set up new h-alpha layer and blended it with around 50% opacity then slightly change the colors in channel mixer.
  10. NGC7000 (North American nebula)Well known emission nebula in Cygnus constellation.Finally after few weeks I've managed to test my new AZ EQ6 mount under fairly good sky in Firle area.Heavier than HEQ5Pro but more sturdy and well machined mount.Scope: Skywatcher EVOSTAR 80ED DS-Pro Mount: AZ EQ6-GT Camera: QHY168C Filter Optolong L-PRO MAX Luminosity Guiding camera: ZWO ASI120MC Guiding scope: SW 9x50 finderscope 24x300s exposure at -10°C (120min total) binning 1x1 20x darks 30x bias 20x flats Another version with added H-alpha frames in more autumn palette. Colour - 24x300s exposure
  11. Thanks. I really like Ha from color cameras..
  12. My filter is screwed into the camera, just before the AR/AR glass on the adaptor. My optical train is: Evostar/35mm distance M48/flattener/camera adapter/filter+filter adapter/camera. I hope I didn't messed it up..;)))
  13. NGC7000 Mono & BW(North America nebula) in Hydrogen alpha is covering an area of more than four times the size of the full moon.Very bad conditions during shooting, tremendous mist came after 1 hour so instead of 2 hrs it's just one.Scope: Skywatcher EVOSTAR 80ED DS-ProMount: HEQ5Pro Camera: QHY168C Filter Baader 7μm H-alpha Guiding camera: ZWO ASI120MC Guiding scope: Finderscope 9x50 12x300s exposure at -10°C (60 min total) binning 1x1 10xdarks 10xbias 20xflats
  14. Yes..With the brighter objects I have to remove flattener next time.. We're learning constantly..
