    Happy New Year Everyone. So finally after 9 months processing, which included a full redo of the RGB blend, I have finished the 2nd Mega Mosaic to complement the 400hr Orion Mosaic myself and Olly made. This mosaic began in 2012 where I collected 30 panes of Luminance. In 2013 I completed 2 rows of RGB. Later in 2015 while taking imaging trips at Ollys in Les Granges, I finished the RGB panels, and I took Ha data to blend into the central rift area. I also took an extra LRGB column on the left hand side of the image. Like the Orion mosaic, this had data at 0.53m with added 1m resolution data for the Eagle, Swan, Lagoon and Trifid nebulae. Again this is the highest resolution image of this area of the sky as far as I am aware of. Thanks Tom.

    Two panels, the lower one from last year. The top one was from this week, with guests, but Tom remembered that he also had a good dose of Shark Nebula data so that went in as well. The lower panel is Ha OIII LRGB for the supernova remnant and planetary nebula while the top is only LRGB. About 50 hours, dual Tak FSQ106N/Atik 11000/SXVH36/Mesu 2000. This time I went for an honest colour, resisting the temptation to try to make the Shark look like an emission nebula! The three VDB objects are, 149, 150 and 152. The PN is G111.0+11.6 (catchy name) and the SNR is ... I've forgotten!!! Olly, Tom and guests.

    First time I have a proper go at some astro with my nifty fifty lens. Canon 600d full spectrum, ISO800, 50mm f1.8 lens stopped at f4, 10x600sec guided on my eq3 pro mount. I love how it came out.

    Almost a month with no clear skies here in the south, but when I open up a little there I am capturing whatever is possible. Even having to get up at 6:00 a.m. did not resist and stayed until midnight to do this capture of Saturn. A photo with almost everything you have right, very visible tracks, Cassini and Encke Division, weak but present Ring C and even the famous polar hexagon. The snag was due to the excessive turbulence that caused the planet to jump too much and caused that edge ring where the north pole is lying in the Cassini Division, but nothing that greatly dismantles this beautiful astrophoto. I suggest to your colleagues to see the image in original size at this link: http://www.astrobin.com/full/298696/0/?nc=astroavani&real=&mod=

    I hope to catch more Lum tomorrow evening with clear skies forecast at the moment - here is a relatively quick process of the Leo Triplet M66/M65 NGC3628 group with 6 hours integration from last night. This is only the second time I have used 600s Lum subs and my skies can just about withstand that duration if I have good transparency and no moon. The tidal tail of NGC3628 is just beginning to reveal itself; it sure is faint. I was inspired to see if I could capture this feature after seeing ShineOn's image and also Olly's magnificant image (amongst other great captures too). Details: William Optics FLT132 at F5.6 QSI683-wsg and Astrodon LRGB filters 18 x 600s Lum 12 x 300s RGB each Avalon Linear Fast Reverse SGP and PI Thanks for looking and fingers crossed for more clear skies .

    I would like to post a big thank you to a trustworthy & fellow astronomer. I recently placed an advert on both SGL and ABS UK to to trade My 17mm Ethos for one of three eyepieces that were of interest to me, and eventually I received response.......... Now if I am honest I did feel a little nervy abut sending my treasured Ethos to someone I didn't know and it did cross my mind if I would ever hear from them again after sending it to them. However, after a few exchanges of e-mails we both agreed on a swap and off I went to the post office. Today I received the eyepiece and I believe this is a wonderful example of something positive happening in a time when doing good seems not so common..... here we have two people sending two very expensive eyepieces across the channel based purely on integrity & trust in one another. In reality either one of us could have pretended that we had sent an eyepiece and thus just keeping the one we received I didn't know Sylvain was a member of SGL until he replied to a post I made about having a Leica zoom in the post..... this just goes to show that SGL is bursting at the seems with great people. I guess this is not really any different to paying someone selling an item and not receiving the goods, and I am sure is an every day event. Anyhow I thought I would post it because it made me feel good about the world. Thank you Sylvain

    Thanks to Knight of Clear Skies for the suggestion that this might be interesting. It was. Firstly I took a lot of persuading that the open cluster-like powder of tiny stars in the centre really was a dwarf galaxy at 81 kiloparsecs.I think it is, though. It was nice, also, to catch a fair amount of patchy IFN including that distinctive streak. I haven't seen this in images I've found but doubtless someone will have caught it before. I really needed good flats for this and finally obtained some for Yves' SXVH36 by shooting them in AstroArt rather than Nebulosity. Flats shot in Nebulosity always over corrected but, at long last, that problem is solved. So this took two nights in the tandem Tak. SQM 21.75 and superb seeing. Atik 11000, 14x10 minutes per colour. SXVH36 19x30 minutes luminance. Total 16.5 hours. Processing in AstroArt, Registar, Pixinsight and Photoshop CS3. For the fullsize (good for fuzzies) click on the image and there should be a button in the bottom left. Olly

    The Milky Way rising in La Palma. I've only just got around to processing this from my trip back in May....so much to do so little time to do it.

    First Jupiter Gif in the 2018 season. There were 12 movies each with 7500 frames. Each film I stacked 3099 frames, I processed and then I made the GIF or AVI using PIPP. March, 08-2018 C14 Edge + ASI 290 + L filter + PM 2X Avani Soares Parsec Observatory

    My friend Alain Paillou offered me for the new year 3D views of some of my high resolution images. The technique used is that of georeferencing from the height data retrieved by stereoscopy by LRO and Kaguya. As Google Earth for Earth. This opens new possibilities in the presentation of our images. It's a big job from specialized software but the results are worth it. I begin to master them and have a lot of exploitable images. If these are caught vertically we can make 3D images from all directions, otherwise we must focus on the angle of the shot because on the other side there will be no filling. Some examples of his work : To compare : If you have glasses for anaglyphs : Clear skies. Luc
