  1. Hi all, my second attempt at imaging over multiple nights, captured 60 mins Ha and a couple of 5 mins on Oiii and Sii on Christmas evening, then added more Oii and Sii on the 30th Total of 60 mins Ha 25 mins Sii and 30 mins Oiii Hubble mapped - SII,Ha,OIII = R,G,B. The Oiii data was very noisy but I'm fairly happy overall, also the ZWO Oiii filter caused a massive ring around Alnitak when stretched ! Comments welcome, I know it needs more data and I will need to learn to be more patient but the year is running out Thanks for looking and have a good 2020.
  2. Here is the North American Nebula in the Hubble pallet and HA. I'm still a relative novice to the Hubble pallet adjustment and didn't want to overcook it? Most probably it can be pushed a little further? The image was capture using the trusty ST10 and the BabyQ FSQ85 over the course of this month. I have been battling with the weather to complete this before my holidays start tomorrow!!! 12x 800sec HA 17x 600sec OIII (2x2binned) 15x 600sec SII (2x2binned) I binned the OIII and SII since these are very weak in the nebula and don't contribute much in the way of detail. The HA data has been used as the GREEN channel and also a Luminance channel for the final image. The HA data is a little wider since I have had some small alignment issues between sessions, still setting up and tearing down my kit each night / session This is the alternative colour schema, I suppose that there is no wrong or right colour schema its just down to your personal preference? Which one do you like?

  4. Now this has probally bin done and if not i already know why but its just a brainwave Basically you know how the hubble telescope looked at a single patch of sky for 11 days straight and brung back a spectacular image well i was thinking could we do that from earth could we setup a global observation of people all around the globe starring at the same patch of sky and gather all that information together and see what image we could create i mean this is just a idea if anyone could help speculate on this and if its even possible to do somethimg this big again im new to all of this and this idea migh not even be possible but if it is and any1 out there could give insight on just how possible it is then please say or if its a bad idea then just say i wont be disshearted but there you go 8 mean i dont even onow how the information would be put together or gatherd but surely theres a way and if not then ao be it would be amazing if this was possible though

  6. We were quite pleased with our snap of the Bat Nebula https://stargazerslounge.com/topic/280222-bat-nebula-eastern-veil-bicolour/ until, that is, we saw this masterpiece from Bill Snyder http://billsnyderastrophotography.com/wp-content/uploads/2013/11/Eastern-Veil-CFHT-Ha-OIII-SII-PS1-V4-CR.jpg Mr Snyder had used all three NB filters, but it was not at all clear to us how he achieved the final result. We captured a couple of SII frames and tried doing multiple different combinations and blends but got nowhere near. So eventually @MrsGnomus e-mailed Bill. He got back to her fairly quickly and said that he started off with a reasonably conventional SHO (Hubble) mix. He then started by following Bob Franke's method - http://www.bf-astro.com/hubbleP.htm I got the SII - last night with a ludicrously bright 'supermoon' looking on. It was noticeable just how much brighter our 'black' level was with the moon around even with the 3nm Astrodon filter. Also the Veil is really getting a bit too low in the sky I think. All told we got around 3 hours of SII last night to go with the 5 hours of Ha and 3 hours 40 mins of OIII. I did a SHO combination - followed by the Franke method and then I got decidedly trigger-happy with the Selective Colour tool in PS. I don't think I would be able to reproduce what I did. I didn't get anywhere near the Snyder image, but the result was 'interesting'. Our bicolour shot is better. Nevertheless, I might try to get some better SII next year when conditions are more favourable. The main lesson we learned was not to try imaging during a near full moon even with 3nm filters. (We simultaneously tried getting some 3nm OIII through our widefield rig - the individual subs looked OK but once processed, it was clear that there was a massive gradient running across the frame which DBE only partially eliminated.) Comments and criticism welcomed as always - this is certainly more of a work-in-progress than a finished effort ....
  7. Spent another cloudy night looking at the iconic HST images and I wondered has anyone tried to make their own version of the Hubble Deepfield image, i.e. Imaging the same piece of apparently empty sky and logging up some serious exposure time to see how deep they can go? I suppose it would be a criminal waste of precious imaging time in the UK but maybe some SGL members around the world blessed with better skies might have given it a try? I get a real buzz from imaging a well known object and finding tiny faint galaxies emerging from the background, I would love to know how far back and distant we can go.......
  8. Recently I decided to open up my wallet widely and go Narrowband... And before my set up comes, I decided to check how to process NB images. Plus, The last half a year was mostly cloudy so I started playing around with Hubble TelescopeRaw Images If someone will decide to kill some cloudy evenings in the same manner, Hubble Telescope raw images are freely available on Hubble Legacy Archive https://hla.stsci.edu And please also share your results on this forum. My first pancake below - "Pilar of Creation" (part of it) combined in Pixinsight. (M16-P1 - [Used Images: hst_10393_13_acs_wfc_f658n_sci & f502n_sci]) P.S. Raw Hubble Images are sooooo ugly... I was very, VERY pessimistic about my experiment initially
  9. Last night I was able to get an unbroken run and get hold of 5 hours of SII to go with the 5 hours of Ha and OIII I had already got for my bicolour Pacman - https://stargazerslounge.com/topic/278251-ngc-281-pacman-nebula-bicolour/ The SII signal was pretty faint in comparison to the Ha and OIII. I also have no real idea how to go about processing these things so a great deal of trial and error was required. Bob Franke's method was sort of what I followed - http://www.bf-astro.com/hubbleP.htm I don't know how 'wild' I should go with the colours in these things. I tried for a colourful but 'semi-realistic' effect. I don't know if I achieved that. The background is a bit darker than is usually recommended. I tried it with a 'lighter' background but, for some reason, I kept coming back to the version I've posted. I am open to any suggestions - well clean ones anyway.....
