  1. I let the dog out in the garden before bedtime last night only to be confronted by the most stunning Moon Halo. I couldn't resist getting my camera... I then wondered, what is going on here? Good old Wikipedia has the following to say about it: "A 22° halo is an optical phenomenon that belongs to the family of ice crystal halos, in the form of a ring with a radius of approximately 22° around the Sun or Moon. When visible around the moon, it is called a moon ring or winter halo. It forms as the sun- or moonlight is refracted in millions of hexagonal ice crystals suspended in the atmosphere.[1] The halo is large; the radius is roughly the size of an outstretched hand at arm's length.[2] A 22° halo may be visible on as many as 100 days per year—much more frequently than rainbows.[3]" So now I know, ish!

    Registar users - was it worth it?

    Sounds like a very wise plan to me... if you have any questions about using APP, don’t hesitate to ask. There are various tutorials on the APP website which are very helpful.

    Registar users - was it worth it?

    I purchased an Owner License at the time APP was first released in 2017. There have been many updated versions, but I have never had to pay an upgrade fee. About my only criticism of APP is that it is constantly being worked on and improved with better implementations of its functionality and new features added quite regularly. This is wonderful, but it also means that I want to reprocess everything with each new release as it creates a better result!!!

    Registar users - was it worth it?

    Interesting stuff. Though I’m not surprised that neither managed to stitch the top and bottom halves together - there appears to be no overlap between them at all! As regards the Framing & Mosaic Wizard - if you plate solve an image with your setup first in SGP it registers the rotation angle of the camera, then when you use the F&M Wizard it displays the mosaic boxes in the appropriate rotation. So long as you don’t move anything, the mosaic will match up perfectly for stitching.

    Messier 81 and 82 panorama

    Spanish skies are undoubtedly better than market town Wiltshire skies and the clear night count in Wiltshire is struggling to get above one or two per New Moon... However, my system is all primed and ready to image M81 at 0.75”/pixel. Let’s see how the images compare!!! I’ll get my coat...

    Barry, that is very interesting indeed to see your UK version for comparison. It renews my hope for UK skies. It’s a lovely image, but the new Spanish version is significantly improved. However, the Spanish image is 56 hours of total integration compared to 8.5 hours of UK time. I wonder... is the only actual advantage of your Spanish sky the higher number of clear nights? Please say yes, whatever the real answer is!!!

    I will just say: Astro Pixel Processor.... €150 outright or €60 for a year. 30 day trial available. It will combine different filters, nights and cameras with ease. I have Registar too, but never use it these days... APP is a complete calibrate, register and stack solution with great initial processing tools too. I complete my processing in Photoshop, but APP does a brilliant job of all the initial stuff. It will do what you are after with ease. It is also probably the best piece of software available for stitching together mosaics.

    Horsehead and Flame - sunglasses please

    what did Mrs Wilson put in your tea while you were processing this??!! Call me old fashioned, but you’ve found the line and taken a step over it with this one! I would love to see one of the ‘calmer’ versions. The detail is great, but the colours look ‘plastic’ to me. It reminds me of the 3D specs requiring comics!

    Barry, this is exquisite. Your best image yet, imho. Chapeau! or should that be: !

    More lunar lunacy!

    Nice ones Daz. My only thought is were you imaging down under?!! The orientation is a bit antipodean! Very interesting to see results from the Esprit 100 - it is a corking scope isn’t it!?! Gav. P.S. Lovely to bump into you at AstroFest - did you give in to temptation at all?!

    Request for Data - The Headphones Nebula

    I'll pass on your subs then, thanks though Dave!
  12. In my recent attempt at imaging The Headphones Nebula / Jones-Emberson 1 / PK 164+31.1, I discovered that it is an extremely faint and diffuse target. My data set is thin and noisy, so I am on the hunt for similar data sets that you lovely SGLers would be happy to share with me, please. My pixel scale is 0.75"/px, so I am looking for data from set-ups in that ballpark. If you have data that you would like to share with this project, please let me know. I am after calibrated (darks, flats & bias) single subs in filters: R, G, B, Ha & OIII. Thank you and I look forward to a torrent of data....!

    Thank you Sara. Really... OIII in this moonlight?? Or are you on Ha? Whatever, yes, OIII is always a bit shy!

    Under Rated Images

    Likes are nice, but if you like your own image, then that's all that really matters. Unless you are producing the image for somebody else, in which case it doesn't matter if you like it, it only matters that they like it! Don't get hung up on likes. As Michael says - the number of people that see your image will hugely depend on when you post the image and how many other posts are flying about at that time. It also depends on the rarity of the image. If you post another image of the Orion Nebula that is pretty good, but at the time of year when the place is saturated with Orion Nebulae... it's going to take one hell of an image to elicit anything more than a viewer passing on to the next post quickly!!! The best feedback possible is in the comments. If somebody takes the time to write a comment then your image touched them. Even better if it touched them to write a helpful bit of advice on how to make your image (or imaging) that little bit better. I don't think a perfect image has ever been posted, anywhere, ever. We all do our best to get as close as we can with the equipment and skies that we have at our disposal. Even better still, write a comment on somebody else's image and encourage or help them to improve...! I do like your images though, good or bad, they are always interesting and challenging. And, you have improved hyper dramatically since a while back when I used to think that your images were 'over processed' - none of that these days. Always worth looking at a Rodd image! Having said all of the above... I like a like as much as the next person. I don't have stuff on Astrobin (well, I do, I have two images that I put up yonks ago, but for some reason just don't use Astrobin... perhaps I should), but I do find that the SGL viewers are a very discerning bunch. A very useful set of critics that only offer their love when it is appropriate to do so. If an image isn't getting the SGL love, then it generally doesn't deserve it!!! If you've read this far, please now like this post......

    Noisy Headphones...

    Wow, excellent! Fibre broadband and clear skies.... I’m coming to Spain.... oh no I’m not, my freedom of movement is about to be relinquished, for the Greater good of the Kingdom............. sorry, no politics...... let’s have a nob gag instead (memories of Ben Elton and Friday Night Live)... I do hope that the few Headphones subs don’t have to wait for the internet upgrade!!
