    Hello all, a quick report of a bolide visible over Scotland last night (14th July 2019) at 23:02 local time. I was parked up in a garage forecourt to collect my son from back shift. The car was parked facing almost due north and I was looking towards the northern horizon for noctilucent clouds as the sky was so clear. The lat long location was at 55.7116, -3.8319. The bolide appeared visible through the windscreen of the car. It was travelling a few degrees west of north and was large and relatively slow travelling for a meteor. It had an observable shape, being round and intensely bright, several magnitudes brighter than the nearly full moon behind me. It was yellow-orange with some hint of green at the margins. Towards the southern (lower) portion of the object there appeared to be a partial halo or arc that appeared to shimmer (much like a bright planet low to the horizon through a 'scope). At the tips of this arc there were streams of plasma following the object. The sighting lasted perhaps a second at most before it dissipated in an intense flash. There was no fragmentation that I could see. I first observed it at around 25 degrees above the horizon and lost it at about 10 degrees. The angle of viewing meant it appeared to be heading almost straight "down" towards the horizon. There was no sonic boom that I could hear, even though I had the window of the car wound down. There was passing traffic however, perhaps masking any low rumble. This was very different to the "normal" meteors that one sees, even during the summer months when there are several showers and something that was quite unusual. I've submitted a report to the UK MON this morning and it will be interesting to see if any other lucky amateur astronomers saw the object. Richard

    Not sure If this has been submitted before. but If not, I thought it remarkable anyway. "NASA’s Curiosity Mars rover can be seen in this image taken from space on 31 May 2019, by the High Resolution Imaging Science Experiment (HiRISE) camera aboard the Mars Reconnaissance Orbiter (MRO). In the image, Curiosity appears as a bluish speck. The image shows Curiosity at a location called “Woodland Bay.” It’s just one of many stops the rover has made in an area referred to as the “clay-bearing unit” on the side of Mount Sharp, a 5-kilometre-tall (3-mile-tall) mountain inside of Gale Crater. Look carefully at the inset image (click on the image to zoom in), and you can make out what it is likely Curiosity’s “head,” technically known as the remote sensing mast. A bright spot appears in the upper-left corner of the rover. At the time this image was acquired, the rover was facing 65 degrees counter clockwise from north, which would put the mast in about the right location to produce this bright spot." This descriptive text is not mine, but arrived with the Image from a Nasa source I believe. Ron.

    10.20, sky fairly clear, still light - Jupiter low, east of south - looked good with his entourage in a straight line - aligned the mount bearing the ED80 on Jupiter. Delta Ser (Serpens Caput, the head of the snake/serpent) - a bright binary, close match, 3.9" separation. 10.27, still quite light, but GoTo put me right on it using x24. I split the pair with x96 - still close, a good match, and a fine sight with the slightly brighter star above the other. Goes to show the pleasure you can have with doubles with even a lightish or polluted sky! Couldn't reach the tail because of bamboos, so I had to move the 'scope and re-align. Theta Ser (Serpens Cauda, the tail), a bright, matched binary, and wide at 22". Again, GoTo hit the target (using SAO numbers as usual), and being 11.00, better darkness was welcome. This was a lovely, bright matched pair - still close at just x24 of course, and sitting off the bottom edge of a near-square of fainter stars. Sigma 2375 - still in the tail - (2)+(2) - a matched pair of inseparable binaries, at 2.6". A very good match indeed, split using x120 and AV, still appearing very close. The fourth target, back to the head, was Sigma 1950, a fairly close match of fainter stars at 3.4". The number was not in the handset, so I hopped from Alphecca, but this one eluded me - assuming it was the right star, it was also very faint. I finished with Graff's Cluster, OC IC4756, in the serpent's tail. It was viewed at x24, with the TV Plossl, the Meade 5000 UWA, and the Myriad MWA, in order of increasing TFOV. All three gave sharp images, dropping away only slightly at the edge. The TV perhaps gave a little more contrast. Nothing much in it really, except for the fields. Staying with the Myriad, OC NGC6633 (Oph) was just at the other side of the 4+ degree field - a denser, brighter object. A very pleasing session, hitting most of the planned targets, and ending after two hours. Doug.

    So that's what a £50 note looks like. Glen.

    This is very costly- just ask me. I would heed Johns advice for brands and maybe place the NEW Televue line in there too, which might be top line Astronomiks. I am still leery of Lumicon eventhough I have 2 superb ones... BUT...the 2" Hb I purchased tainted me for the brand possibly forever. Same goes for Kniselys Orion Ultrablock recommendation, I got burned on that one too. Knisely is a fantastic resource and honest- some of these brands can have extreme sample to sample variation though and brand quality can change as well ie Lumicon. Our DGM NPB is very good, the older Astronomik OIII is VG but a bit wide, the older Astronomik Hb of mine is superb, and the older non laminated Lumicon UHC and OIII are the top of the top... these are my good filters. If it were me I'd go Astronomik or NEW Televue. Eagerly waiting @John test results of the new Televue filters.

    Astrodarkness is still almost two months away. This is a reprocess of data I captured in October 2017 with my then new ASI174. 60 x 45 s each of RGB 163 x 30 s L (3.6 hours total.) All captured at -20 C, gain 300 ASI174MM-Cool with ZWO LRGB filters. Telescope SW 150-PDS on a SW AZ-EQ6 mount, no guiding Captured with Ekos/Kstars, processed in PixInsight. And the old version

    Hi, Got my Intes-Micro MN56 into the garden on Tuesday evening of 9th July 2019 to do some Moon and Jupiter imaging. Just as I was about to end my session, I noticed Saturn really low down in the sky, so I took a few shots of it. Glad I did so. This is one of them. Image Info:- Intes-Micro MN56 Telescope with x2 Meade APO Barlow Lens ZWOASI178MC camera 704 frames taken at 3096x2080 resolution. Processed through Autostakkert with a 30% stack. Tweaked in GIMP.

    Another attemp on Jupiter from me, a novice on astrophotography, lol. But this time image is taken using Orion Shorty Plus 2X Barlow. Image is still captured using Canon 60D, prime focus on CPC1100. Stacked and processed using Registax and Instagram as usual Two attemps on Jupiter which produce more or less the same image. Seeing from the image, I think this barlow degrade image quality quite significant. Please advise if any. Thanks Cheers

    Continuing the epic, now a picture at a low angle of illumination of the landing place of Apollo 16. We can see that this place was much more wild than the place where Apollo 11 landed. https://www.astrobin.com/full/414691/0/?nc=user
