    I spent the evening up on Hergest Ridge in Kington Herefordshire again last night as the weather was good. I knew that it had been raining up there earlier in the week and I was hopeful that there were going to be some pools of water to catch some reflections from the stars during the time lapse. I found one pool which is where I set my Sony A7Sii and Tamron 15-30mm f2.8 zoom lens on my Rhino Camera Gear Evo Carbon slider with motion and arc. I shot two short time lapse videos during the night shooting a total of over 700x30 second exposures with the zoom lens at the 15mm setting and f2.8 and at ISO 25600. Although it was quite breezy the water in the pool remained calm allowing for some nice reflections. In the second clip the very bright areas are from the light pollution in Leominster and Kington The video can be seen at the link below and is best viewed in at least HD Best wishes Gordon

    Its not easy being an Astronomer here in Australia. Below is a screenshot of the homepage of Australia's new space agency,,,,maybe. Someone went to a lot of trouble building that site. You can view the site by clicking here Pretty good humour IMO. Ray

    Incredible geometrics. An optical illusion on my screen, the shapes can appear inward or outward depending on how you glance at the screen. Ray

    The missus brought these home for dinner. But as they are such a beautiful example of fractals in Nature they had to get macro'd first Here we have the wonderful Romanesco Broccoli. Greg

    Cheers guys. The Hyperstar image is my most ripped-off image as this is the galaxy cluster where Zwicky first worked out there must be dark matter. Greg

    Yep I have used the RGB data as a pseudo Luminance in the past, and as you say Ray, apart from fine detail there is no discernible difference that I could see. Having said that I still shoot Luminance to get the best possible detail in all my shots. Shane

    Thank you. As far as astro presents, none so far. I would gladly be satisfied with a good night of seeing! Have to work all week long and my astronomy adventures are limited to Saturday nights...weather permitting. Thanks again and clear skies to you all. Eric One year closer to the big dirt nap!

    It just doesn't get any better than this for my locale. Almost, got the Enke division. I may try stacking less frames just to see if I can get a little more detail. Same image, just displayed differently. With the ZWO ASI120mm. Tim.

    As a true "unstable" Victorian I will be going for the Tigers but I believe the crows will be way too good for them. We are heading off in the camper trailer tomorrow for a weekend away and will be watching the footy and downing a few (read lots) of beverages with some friends at the little town of Yackandandah.

    You shouldn't have any issues now. Everything is very stable here except for Shane. I'll be watching with my low carb beers, thats for sure. I need a van for super dark sky travel as well I think. Ray

    Thanks fellas...I don't know what it is about me but the passwords keep on getting "lost" after sometimes only a single re-visit - happens here & on CN also & I have to re-load/save them...& it might hold it for a while, but then it happens again... Enough whining...Ray, we were very satisfied with the cloud definition last year in our Mars images - we're really hoping with next year's "super-Mars" at 24 arc-secs that some special nights might pop up: atm trying to do a few jobs around the house so we can leave straight after the Grand Final this Saturday (C'arn the Crows!!! :lol:) because there "might" be a couple of nice nights after that... We'll head off for some fishing R&R also after any imaging we manage to get, because a by-product of not having many decent imaging opportunities in the last few months means we don't get to be out in the van as much as we like...& we get a bit toey staying at home too much!

    Well, this is kinda hard 'cos even though this year has presented poor seeing for a lot of the time we still have oodles of images since I last posted something here...which were 2015 images. Neptune & Uranus were the subjects I posted images of on MAS back then & we had only just commenced imaging Neptune...since then we have been in a couple of pro-am collaborations for Neptune & our (Pat & my) work was presented at the international Planetary Scientists conventions as part of this, one Neptune night's work capturing several storm spots including one that only the Hubble had imaged & which our image accorded with "point by point except for one small artefact" as Prof. Ricardo noted at the time. This year the Keck only recently made a fanfare news release about a very large storm on Neptune's EQ where the winds rage at around 1000km/hr making the storm that was imaged there very unusual: in actual fact Pat & I had discovered this storm first quite a while earlier & our images on June 10th & July 14th were the first & last time it was imaged...this period being quite amazing for such a large storm to stay together in those conditions where they are "normally" never found. Here's the BAA link to our feat as well as the link there to the Keck release: https://britastro.org/node/10860 But I'll kick off with a few Jovian images from 2016/7 then some Saturns of the same vintage & Mars from last year also if I can fit them...apologies for the haphazard array but I have drives coming out of my ears half the time..!

    That's right, I remember reading about this galaxy now. There was a micro quasar predicted but it didn't fit the bill. Awesome galaxy though. Well captured. Ray

    Yep the secondary does dew up pretty easily mate, I might have to look into a strap around the end of the main tube to see if that works. Shane

    Joke right? No such thing as a digital sundial, or is there? Just 3D printed out this little beauty. Shows 10:20 when it was actually 10:23 and shows mid-day when it was spot-on mid-day. Resolution of the sundial is 20-minutes with the printer at its highest resolution of 0.1mm. Greg

    After 47-hours and 56-minutes on the Anet A6 3D printer using Rigid.Ink black pla - this beauty emerged 110mm tall with a 0.2mm resolution - this is the famous MANDELBULB - the 3D equivalent of the 2D Mandelbrot set. Looks way better in the hand than it does in the photo. Greg

    Ooops - maybe this is worthwhile if it fits/works...I haven't loaded the 2017 image yet but it gives another spin to the ring tilt as opposed to the set of still images above. (which do include 2017!)

    Wow mate. I saw an incredible documentary which had a high focus on diabetes and how the food industry lies to us to make money. Its called "What the Health". http://www.whatthehealthfilm.com/ A great watch at the very least. Ray

    "Time flies" for sure Ray - I reckon it might've been your #2 who was very young who I referred to above... I've been a bit slack about my diabetes so hopefully the kick up my pants can help me get it back under control...can do funny things unfortunately. Hi Shane! I'll put a "compendium" together of our images & post 'em in the next day or so...

    First night out and trying the strap out using only the power supply lead with adjuster. Luckily I have the original mount power lead with the 3.5mm jack and cigarette plug to go into the power supply I purchased as I will need to get a longer RCA lead made to reach the controller. It is a rather heavy dew here at the moment and the dew strap is keeping the guide scope wonderfully clear or I would already be done after about 90 minutes imaging. I am rather impressed and quite happy with the budget Prostar strap, without the included lead with independant power control I would definately be buggered. I reccommend them as an alternative to more expensive brands without hesitation. I would say the only down side is the lack of length of the RCA lead, as it is too short to reach the controller which is to be mounted on the pier. I emailed Steve about this as a bit of feedback.
