  1. Am I a dinosaur?

    How about using narrowband filters and then creating Hubble palette images or bi colour images...... here the colour creativity is endless....... is this not creative? In terrestrial photography it's something of a given that for example the grass is green..... if you mixed the colours so that the grass became a delectable hue of purple I suspect this would not be viewed as creative, but downright madness.... In astrophotography you can make the colours as you see fit (OK there are some 'normal' parameters, but you can think outside the box with colours) - To me this is creativity
  2. LDN1622 - The Bogeyman mosaic in mono

    Sure it is...... but it's not a dark sky in the sense of the word... sure I tend to have more clear than many but not darker
  3. LDN1622 - The Bogeyman mosaic in mono

    About 20.... dark skies I believe are over 21?
  4. LDN1622 - The Bogeyman mosaic in mono

    Many thanks! I'd like to squash the idea that I have dark skies......... I really don't. I live 20km from Spains third largest city
  5. This was my exact reason for moving from the ODK10 to a refractor. I had it for 2 seasons and we have a pretty terrible time over here with yellow pine pollen in the spring. I knew that one day I was going to have to tackle a mirror clean and there was no way I was up for that..... so I sold the scope before the mirrors got that bad and settled on a 152mm refractor.... heaven!!
  6. If you are using a DSLR then you can use the propitiatory software - So for example Canon utilities works really well on the PC and you can control all that you need. The newer Canon's as well can do live view on the OC via this program, so you will have an easier time focusing
  7. Barnard 39 in Monoceros

    Oh very nice...... I like that a lot 👍🏻
  8. LDN1622 - The Bogeyman mosaic in mono

    Thanks Barry - Maybe I will only ever have it in mono!!! Cheers Chris - While I can't comment on anyone elses noise, this one is not ideal for me
  9. LDN1622 - The Bogeyman mosaic in mono

    Thanks Dave! Mono it is!!! Thank you Peter - No plans for colour this year!!! Thanks Steve - The processing was tricky for such short data sets Thanks Pieter - I think it suits mono well .... Or am I just lazy?
  10. LDN1622 - The Bogeyman mosaic in mono

    This is a faint target Carole, so I reckon you'd need quite some exposure length to really get to grips with the potential noise. You should get plate solving, then you need never worry about a coordinate again!!! Thanks Gorann, I don't think there's going to be much more progress this year! It is called the Bogeyman and it isn't a name I made up I don't recommend 2.5h of data per pane!!
  11. The Monkey Head Nebula in Hubble Palette

    I REALLY like that - The SII has really added so much to this image. Despite my monkey thoughts, there's nothing dull and boring here....... Fantastic
  12. LDN1622 - The Bogeyman mosaic in mono

    Thanks Graeme - I looked about the net to find something that I understood then put something on my website about it Thanks Olly - For only 2.5h data per pane I think it's quite noisy I'd have loved more data and made it smoother. Colour you say? Not this year!!!! I'm not sure about colour either!!!
  13. Great top widefield images Well done
  14. LDN1622 - The Bogeyman mosaic in mono

    Thanks Richard - Glad that you like it Thanks Many thanks DP Thanks Graeme - Now that is very interesting! I wouldn't have thought that a reflection nebula would have shown up at all in Ha.......... But you've certainly explained the star that isn't round Just reading about it ....... It is the bright Pre-main-sequence star HBC515 ... Need to do some more reading as I have no idea what that actually means!! If anyone is interested http://iopscience.iop.org/article/10.1088/0004-6256/139/4/1668/pdf
  15. LDN 1622 is located near the galaxy plane in the constellation of Orion. It is close to Barnards loop, a huge cloud that surrounds the emission nebulas found in the Belt and Sword of Orion. It is thought to be much closer to the more famous Orion Nebula, perhaps only 500 light years away. I have wanted to do this for a long time, but various things have conspired against me (as per usual) and so I have stopped at this point for the year. It's a 6 pane mosaic and has so little data compared to what I would normally use..... But I thought that it stood up as a mono image. I was looking closely at the 'nose' as the star looked a little smeared, but it was in all the subs and when I looked more closely at some comparable images out there, it's an area of some light nebulosity in Ha it would seem. ** Thanks to Graeme - He has identified the 'smeared' star in the nose as Parsamian 3 - A pre-main-sequence star - You can read about it here ** Oh my goodness - I've taken a scientific picture perhaps!!!! Details: Mount: Mesu200 Camera: QSI690 with 3nm Ha Chroma filter Scope: TMB 152/1200 6 Panes in total with 5x1800s in each pane totalling 15 hours of total exposure.
