    M31 - my first attempt

    Thanks VLAV. Well spotted! I check it out. Peter

    M31 - my first attempt

    It was a Teleskop Service Star71 (effectively a clone of a William Optics Star71). F4.9

    Another M81

    Thanks Olly - that's another new tip for me!

    Nice job Rodd. I've never seen M104 in such a wide field setting. It's really striking just how lonely a galaxy can be! Peter

    Thanks Barry - keep the tips and suggestions coming. They are really appreciated. Peter

    I'm a Photoshop man and have never fathomed PI, but I think Photoshop achieves a similar result. It's certainly warmer to my eye!

    I'm interested in how it will work too! There are a few challenges that give me anxiety: getting SGP to know which of 2 identical cameras is which; and avoiding differential flexure being two of them. I'll be using one Lakeside and 2 Optec focusers to avoid the challenge of 3 Lakesides. I'll let you know how it goes. Peter

    A reprocess of data from 2 years ago to (a) see how much my processing has evolved since then, and (b) keep me out of mischief while waiting to set up my ridiculously-ambitious triple rig at e-Eye in Spain at the end of the month. These days I would prefer to have much more data than this (hence the advent of the triple rig) since more data would have enabled me to bring out more detail and some IFN, but this is what I had to play with. 9h15m total integration (39x300s L, 14x300s R, G and B, 5x1800s Ha). Alcalalí, Spain 24-25/1/2017. APM TMB 152 F8 LZOS, 10 Micron GM2000HPS, QSI6120wsg8 Processed in CCDStack2 and Photoshop CS2

    NGC 1333 - high resolution New Year's delight

    Quite magnificent Barry. A beautiful target beautifully processed to a level that would justify an APOD. I have to confess that I've found this one really difficult - and after spending days and days wrestling with processing it I gave up in the end! Well done!

    NGC 1514 - The Crystal Ball Nebula

    Thanks Mark. It's a pretty target, but very small - and I found it quite challenging. It needs a fair bit of data to be able to pull out the structure of the nebula.

    NGC 1514 - The Crystal Ball Nebula

    Thanks Martin. I used the Ha to pull out more structure detail of the nebula in the synthetic luminance, but only used the RGB for colour.
  15. NGC 1514 is a planetary nebula in the constellation Taurus that was discovered by William Herschel on November 13, 1790, describing it "A most singular phaenomenon" and forcing him to rethink his ideas on the construction of the heavens. Up until this point Herschel was convinced that all nebulae consisted of masses of stars too remote to resolve, but now here was a single star "surrounded with a faintly luminous atmosphere." He went on to conclude "Our judgement I may venture to say, will be, that the nebulosity about the star is not of a starry nature". It has since been conjectured that the nebula in fact envelops a tightly orbiting double star with a period of up to 10 days. Gas is presumably expanding away from the larger star of the pair. 15 hours 30 minutes total capture R 20x300s G 20x300s B 20x300s Ha 21x1800s Image captured remotely at Alcalali, Spain 25 Oct 2018 - 4 Nov 2018 APM TMB 152 F8 LZOS, 10 Micron GM2000HPS, QSI6120ws8
