    This one has been sitting around for quite a while... usual thing where I only post when it's not been tweaked for a while! This is a 2 pane mosaic with a couple of new things to me..... The FOV is small and so when you look at it in comparison with the complete Heart nebula complex it really puts my differing FOV's into context. I have processed this one differently to my usual as I felt that when I did my more normal colours it looked a little flat. Leaving some green and cyan seemed to give it a depth that was otherwise lost. This is 50 hours worth of total exposure. Details: Mount: mesu 200 Scope: TMB 152/1200 Camera: QSI690 ws-g with 3nm Chroma narrowband filters. Each pane had the following data.... 20x1800s Ha, 15x1800s OIII and 15x1800s SII. It was pre processed, calibrated and also stitched together in APP. You can see a larger version and information about how it fits in with IC1805 here

    My youngest decided to take a look through my scope while it was cooling this evening. “My see the stars” were her words! I think she thought it was a frac though!

    After a week of cloud, tonight clear skies appeared and I was able to have a play with my new scope and mount. SW London is not exactly the best place to use a scope like this but I had fun anyway. Set up was quick and within about 15 mins the tec was aligned on the panther mount ready for goto and tracking. My sky surfer v finder comfortably cleared the ‘wheel’ handle so that means it will stay in place. First up was M42 and in particular the trapezium. Seeing must have been ok since E and F were obvious. With my oiii filter in place, there were lovely long tendrils of nebula emerging from the ‘mouth’. Sigma orionis was fantastic with all 4 stars very ball like and obvious. Then onto NGC 2169. Lovely 37 with a cheeky double at the top of the 3 (thanks Stu). Auriga clusters of m36, 37 and 38 were nice but I think the poor skies didn’t bring out the stars so they looked a bit sparse. I then followed Nick’s early winter gems suggestions. Ngc2301 was very much like a dragon with wings and a really nice selection of coloured stars. One to revisit again - liked it a lot. Beta monocerotis was a new one for me and a very straight clear split. The tec is clearly well suited to doubles/triples etc. Hind’s crimson star was another new one for me and boy was it crimson - real surprise this one. Again the tec showed the colour and tight star shape very well. Tegmine needed a good level of magnification to split it into 3 - trickier than double double by a margin I would say. Then I had another look at m42 before finishing with the moon. I’m don’t observe the moon very often but with the 4mm DeLite giving 280x it was a delight!! I suffer to some extent with floaters but it’s clear the tec soaks up magnification easier than any other scope I’ve had. In fact I was surprised how often I used the 4mm this evening since I rarely go over 200x. The tec was at ease with this - decent seeing I guess. The panther mount is amazing. Easy to align, holds the tec comfortably and the goto and tracking particularly using sky safari and skyfi are very easy. I could cover a lot if I wanted but could also concentrate on an object for an extended period due to the very accurate tracking. Of this new setup it’s the mount that has made the leap forward in ability compared to my other setups. In respect of the Tec, the build quality is excellent - very close to my AP. The 3.5 inch feathertouch focuser is brilliant, better in my opinion than the AP focuser. The feathertouch makes fine focusing such an easy task. So I think I’ve found my dream visual setup. I’m looking forward to try my night vision monoculars with it (still waiting for the adapters from the US) The only slight negative is the weight and length. The 12kg weight means I have to be very careful when mounting it particularly as the mounting point is quite high on the panther. Also the extra length does mean that the viewing height can change markedly- I’m pleased I got the pier extension for viewing those objects near the zenith (rather than be laying on the ground!) Howver, thsee issues come with all bigger fracs. In summary, a great first light and I’m looking forward to taking it to a dark site to get it to strut it’s stuff more

    Another widefield I took on 25th/26th Nov using my Baader modded 350d and Canon 85mm EF f1.8 USM (working at f4.5). This is 21x5min, so 1h45m total taken at ISO400 using an IDAS P2 filter from here in Oxfordshire. I'm sure the region doesn't need too much introduction. To be honest, it needs a lot more exposure, and arguably taking with something more sensitive with less read noise! Being a bit further south would help me too...there was a heavy dose of DBE to sort the gradients out here. Barnard's Loop, the Bogeyman, M42/3, Flame and Horsehead all relatively easy, and the dusty stuff (part of The Orion Molecular Cloud Complex) that extends between them passing by M78 is reasonably obvious, though the fainter stuff is all a bit noisy still. There's also the bluish nebulosity LBN 915 *just* on the limit of visibility to the right of Sh2-278 that extends around the right of eta Orionis. As I said though, it all needs much greater SNR, and less need to resort to MMT for noise reduction... (any more and it started to adversely affect the image). Both images reduced to 2048px width here for convenience. Thanks for looking.

    Just as I was going to bed, I spotted that the skies had suddenly cleared. I set up the 80mm APM triplet, with ASI178MM and rattled off 4000 frames. This is the result of stacking 1000 of them and sharpening in ImPPG. Needs to be seen at full resolution.

    Hi, Asteroid (3200) Phaethon has been in the news lately. It's a 5 km-wide PHA, the source of the Geminid meteors and currently at its closest for a long time. It passes just 0.069 astronomical units (10.3 million kilometres) from Earth at 23 UT (11pm GMT) on 16 December. Then there’s a 76-year wait when it will attain magnitude +9.4 on 14 December 2093, at 0.0198 astronomical units (2.96 million kilometres or 7.7 lunar distances) from our planet. It's got a highly eccentric orbit with a period of 523½ days that brings it closer to the Sun than any other named asteroid. For ten nights starting 8 December, it is 12th-magnitude or brighter and well placed in the Northern Hemisphere as it speeds up through Auriga, Perseus, Andromeda, Pisces and Pegasus at a rate of up to 15 degrees/day. I had a go at capturing it last night, with intention of producing a light curve to show its rotation. Unfortunately gusty winds and passing clouds messed the imaging up a bit, but I did manage to get some captures of it. It was moving at a rate of 5.5 arcseconds a minute, and its motion was very noticeable in only 30 second exposures. Here's 16 minutes of 30s exposures, stacked in DSS. Field of view about 33' x 24': And here's an animation. 7 frames, each consisting of 5 stacked 30s exposures. It really speeds up over the next few days (from Astronomy Now):

    Tonight, three pints down, I came home and the wind had dropped a bit, sky had clear patches, and I had new EP sitting in the kitchen. I received a 16mm 82deg Nirvana in the post yesterday from an SGL member - my first 82deg EP. I was itching to try it out in the 12". After my typical three - Double Cluster, M37 and M42 - I figured I'd try for M33. M31 on the way, never impressed me yet, as if it doesn't really count. The moon was up and bright but further away than last time. I knew, by gross proportions, where to find it. So I red-dotted to somewhere and began a spiral search. It didn't take that long until a patch, in seemingly otherwise empty space, presented itself - most easily discernible while actually moving the scope. I tried flicking my eyes around, looking elsewhere, tried the other eye, closed both eyes for a moment and tried to surprise it, etc... but I figure both the beer and the moon were against me. I had no doubts at all that I was looking directly towards M33, confirmed since by the adjacent star patterns. It's not that long since I imaged M33 in my 4", since sold - that was my first ever self-sight of another galaxy (other than M31) - but tonight, I got my first galactic visual (other than M31). I didn't try any other EP, I only had the 16mm outside with me. No structure, no extent, no core, just a presence, but still a first. I don't know what I've got against M31, but I'll be back to M33 again.

    Trying to utilise the dual rig to the full this is 24x300s from 414ex-osc plus 12x180s of LRGB followed by 10x600s of Ha from 428ex-mono. Pre-processed in PI plus initial noise reduction and stretch; colour processed in PS. Would value any comments or suggestions on improving the end result. Thank you for looking.

    I shot last night an Oxygen featureless panel around Orion mainly for the stars. However, I didn't immediately take the camera and the lens off so I shot also the moon through the O3 filter (I was too lazy to refocus for another filter). This is at ~300mm focal length with an ASI1600. Not bad for such a short lens.

    Some of you already know this, having followed my threads on the indi-forum and maybe the zwo users group. A while ago I started testing INDI on a 64 bit Rock64 sbc, to replace my Raspberry Pi. The advantage of using a Rock64 computer is that it is a faster machine and it has USB3. ZWO recommends using their cameras on USB3 machines to reduce amp-glow. Amp-glow in their cameras is (partially?) caused by the slow read out when using USB2. Installing the indi library and getting that to work wasn't much of an issue, but I never got the zwo efw to work. After some discussions on the zwo forum, the bug was identified (cross compiler problem) and solved. Jasem Mutlaq of INDI updated the library, and now it all works. Here's a write up of how I installed everything: -------------------start of write up------------------------- Rock64 ubuntu installation Installation downloads to my windows machine: download xenial-mate-rock64-0.5.10-118-arm64 from https://github.com/ayufan-rock64/linux-build/releases This is a stable release extracted using 7zip written to sd-card using win32diskimager (Btw, this is not the final release, see below) Booted the Rock64: this starts the mate desktop (default login is rock64/rock64, but yo might want to change the password at least) connected to hdmi, tplink usb device connects to wifi. in the network manager for the wifi network (that's where you've set the SSID, passkey), allow the network (wifi) connection for all users Installation of indi: installed indilib full and kstars bleeding, see the ubuntu instructions on the indilib website. Next is to install the indi web manager: Installed pip: sudo apt-get install python-pip This installed an older version. However, upgrading did install the newest. Tried installing indi web manager, but got a compilation error: Python.h - no such file or directory. Solution: install Python-dev $ sudo apt-get install python-dev // this is for python 2.7 (for Python 3.x use:) $ sudo apt-get install python3-dev 171104: installed latest pre-release 0.6.x in order to get access to usb3 patches EFW doesn't work with rock64. Tried a lot. Among other things, building indi from source. Reinstalled SD card several times, trying several pre-releases. The Ubuntu release I use now is: Ubuntu 16.04.3 LTS (GNU/Linux 4.4.77-rockchip-ayufan-136 aarch64) ... project on hold, waiting for ZWO fix and work getting in the way ... 171208: after communicating with ZWO (zwoug forum) and on the indi forum, the filter wheel issue is solved. It turned out to be a cross compiler bug in the asi driver for the wheel. ZWO issued a fix that was implemented by Jasem Mutlaq of INDI. All I had to do was update and upgrade the system. Now it works fine. -------------------end of write up--------------------------- Image download seems faster than on the Raspberry Pi. So far I've only tested it with a USB2 cable in the USB3 connector (the USB3 cable has a kink). But setting the bandwidth in the indi control panel of Ekos to 100, I seem to get a substantially faster download of captured images to my computer. No first light yet, due to clouds (isn't there a "sudo apt-get upgrade" for that?) For those of you willing to try this, installation should be trouble free if you use Ubuntu and connect to the indi repository. Just install and upgrade should get you a workable solution. And what about the amp-glow? Well, so far the only test I've been able to do is indoors with an uncooled camera, using a USB2 cable in a USB3 port. As I mentioned, I set bandwidth in the indi control panel of the camera to 100, and seem to get a fast download time to my laptop (camera --> usb3-ish --> Rock64 --> wifi --> laptop). But there's still amp-glow. This isn't a magic bullet; all I hope for is an improvement. And even if it doesn't reduce the amp glow, I still can squeeze out a few more exposures per session if download time is shorter. And with short exposures, that makes a difference. Hope this can be of use to someone.

    There's a lunar occultation of Regulus around 10.15 - you'll need a clear north east horizon as it will be quite low in the sky. It's been a mix of snow showers and crisp skies here, but could be worth catching, along with some early Geminids. I think the goose down underwear might be required though ! andrew

    And there you have the problem. It isn't that cars can't evolve, but that we can't. To fit into that imaginary car, people would need to be shrunk to the size where 1 000 fit into the palm of your hand. The economics and physics of car manufacturing is completely different from electronics. And astro gear manufacturing is completely different still. Plus, as mentioned before, the market is different. A former ceo of IBM once said that the entire computer market was limited to about four units. Boy, was he wrong. As for glass not changing, that's physics. Even the material used for computers hasn't changed. It's still silicon, aluminium and gold, mostly. But unlike electronics, you can't really miniaturise scopes. We want aperture and focal length. Actually, now I come to think of it, a lot has happened. Who would have thought 10 years ago that excellent astro images could be produced by cmos and ordinary lenses. Yet, that's where we're headed with cooled cmos from the likes of zwo, qhy and atik. And computerised goto telescopes are available to the masses, thanks to skywatcher and others. Direct drive, super accurate mounts that don't need guiding are being developed and affordable to more and more people. But again, the market is too small for direct product development on the same scale as for computers and cars. One indicator of this is the lack of large size mono cmos. Since the market is in consumer cameras, there's no incentive for the manufacturers to move from osc to mono.

    As always this is a wip (work in progress) and is actually a violation of a simple rule a former member on here SteveL gave me when I was starting out with imaging and he was assisting with the processing. He got me to promise to never capture less than an hour on any object. Well, this one breaks that rule (just), sorry... but circumstances in the shape of excessive cumulus clouds keep getting in the way. This is 11x 5 minute exposures of the Rosette Nebula through a little Borg 55FL... one of the reasons I wanted to try a little Borg was for the wide fields one can get.. Unfortunately with this image I've found myself wanting a slightly wider field of view - I didn't know there was so much to capture around the Rosette rather than just the object itself... Anyway, here it is. Very much a WIP and I'll hopefully be adding a lot more data to it weather permitting as I'd like more data to better bring out the fainter nebulosity that extends to the left and lower left in the picture. I really don't want to do a mosaic but I wonder how far those 'plumes' for a lack of a better word go to the left Detaily stuff: 11x 5 minute subs in Ha (Baader 3.5nm enforced filter) Borg 55FL @ f/3.6 with a ZWO ASI1600mm-cooled Captured, guided, controlled through the SkyX, processed in Pixinsight, all on a Mac I've gone heavier on the noise reduction than I'd like but more data will remove the need for that!

A big shout out to the Myriad 100°, I don't use it much as I have an F10 SCT, but when I do its great (on brighter objects like the moon, planets > if you can ever see 'em, and brighter planetary nebulae and Globs ), and especially good on my friends 14" Dob. Clear skies!

    Jim A is pretty good and programmes like this were made as primers for the Open University I think so they're a bit above the Brian Cox level. I sometimes wonder whether it is more confusing to use analogies to try and explain things like quantum mechanics than it would be to actually teach people some physics. I discussed the programme afterwards with my OH, who is not daft by any means, but she doesn't have a scientific background. She found the analogies too muddled and convoluted. So I explained about photons and polarisation and the supposition of states and the creation of entanglement in simple terms and she said yes I get all that, why didn't Jim A say that instead of muddling it up with coins and gloves and whatnot.

    Make sure you don't confuse white light with Ha observing. Absolutely no need for a front filter and a Herschel wedge. They both do a job of reducing the intensity of light and heat reaching the eyepiece and your eye. Doubling up on the reduction would, I imagine, result in a view so dim it would not be worthwhile. Not sure why such worry about techniques and equipment which is well established and used safely by so many people without any problems. I use a Herschel Wedge with an expensive refractor (Takahashi FC-100DC) and have never had any problems at all. If the Wedge falls off the only risk is a hot leg!

    Just after midnight there were some decent size holes in the cloud so I setup the Mak. There was no time to wait for cooling so I should have used the refractor really but it was too windy for a long tube. The clouds were moving fast but I did manage to grab 20 frames and stack them. The IQ was terrible due to the warm scope no doubt but here's the result.

    Ok. I can only speak for the 450D though. Turn the camera on. Press menu (top left) Along the top row there is seven icons. Arrow across to the sixth icon (yellowish) using the butttons that surround SET. Click on Custom Functions (top one) Press SET Again using the left and right buttons scroll through untill you see long exposure noise reduction. TURN OFF. Scroll to next which is High ISO noise reduction. TURN OFF. I,m not saying this is correct, but it is what i have done, need to to test out. Cheers. Mick.

    Hi all. I've been very lucky to have some so many clear nights recently. For the first time since i began imaging i actually have a backlog of data. The ha version is 10 hrs in 150 second subs at unity gain captured over 2 nights. I used data i had from the Star 71 to add some detail to Orion and the Horsehead. The Ha Rgb version is 20 hrs combined. The rgb is 10 hrs in 150 second subs at 0 gain. Along with the ha captured over 2 nights. I blended the ha as a red layer and a little as a luminance layer. Thanks for looking and hope you like it. Richard.

    I shot some short Ha subs at 0.9"PP in the TEC/Atik 460 with a view to blending them into some widefield Ha data. However, the fish mouth looked remarkably like a fish mouth in the incoming subs so I thought it would be fun to process a version which accentuated this feature. It's a mixture of one minute and two minute stacks, layer masked together in Ps. Then I added this Ha to a lower resolution LRGB M42 taken at 1.8"PP. I'll use this to enhance my existing TEC M42 but here it is anyway. It's the Ha which is the really fishy one for me... One of these days I must try to catch 6 Trapezium stars by using the planetary camera in the 14 inch Meade. Olly

    I have had real problems getting anything like a nice image with this one. Part of the problem was that the framing shifted during imaging and the left half of the image was only half of the subs stacked and I just could not get a decent colour balance. It was also imaged during 'mushy' skies. So I decided to just concentrate on the centre part of the image, that at least stacked all the lights. Ha was used as luminence and added to the red channel. there was 11 X 10 min, iso 1600 Ha subs and 29 X 5 min, iso 1600 RGB subs. Total 4 hrs 25 min integration time. This is the best I can do, better than my first effort. It's not a very photogenic nebula, to my eyes. I don't want to hurt its feelings but it has none of the artistic merit of Orion, Horse and Flame, Elephant etc...

    All three you mention are BA-8 type binoculars, and the 70mm types weigh just a little less than the Helios LightQuest 16x80. The Apollo 15x70 I had was a great workhorse, great optics, very nice to use, but the LightQuest is definitely better.

    Being at a truly dark site can be disconcerting trying to find recognizeable constellations because so many more naked eye stars are visible that they can obscure familiar asterisms.

    I just managed to grab a quick first light with the new binoculars, seizing a short gap in the cloud cover. I first went for the Pleiades, and they were beautifully crisp. In Auriga, M36, M37, and M38 were readily picked up, with more stellar detail visible than with the Helios Apollo 15x70, and even the Opticron 16x80, despite some encroaching moonlight. I swung to Orion, and the nebula stood out nicely. Finally, I moved to the moon. It was low in the sky, but I cannot recall ever seeing a better lunar view. Some CA was visible on the limb, especially when near the edge of the field, but nothing disturbing. I must say I am very impressed. I did all these observations without monopod, as clouds were rushing in, but still the binoculars handled very well indeed.

    This has about five hours of total integration- three hours on the luminance and about 30 mins each of RGBHa. This data is from FSQ85 with 0.73 reducer in 5 min exposures on my old NEQ6 mount. Two years old data. Anyway thought I'd give it a reprocess. Struggling to get rid of the slight salmon tint and bring some of the yellow of the stars out. Will play around a bit more tomorrow.

    Matthew, it was reading that you had sprained your wrist lifting your scope that made my decision to stick at 160mm. Although only 15cm longer I think your scope (lovely btw!) is about double the weight, and also more front heavy. Although MikeDNight possibly doesn’t believe me ? I really think (hope) this is the last scope purchase for me for a loooong time. Over the past 18 months I’ve been on a bit of binge and tried out several. I think my current 85mm (for overseas travel), 100mm (for grab and go), 130mm (for easy setup proper views) and 160mm (for serious session views), plus 60mm solar cover my requirements suitably. ?

    A decent 8 - 24mm Zoom eyepiece is a very good thing to invest in. Not only for your omn eyes, but for outreach work in your local park(s), schools, etc. And for kids - as kids (including the one in all of us) will be delighted for "Skydiving on the Moon!" Viewing colourful double-stars is a great nighttime adventure - watching the two colours split wider and wider in the eyepiece as you add more magnification is a treat - for adults and the young ones. Albireo is a show-stopper! Something that's also a very good choice to bring with, if possible, is a good adjustable observing-chair. It's best to have your audience relaxed and comfortable at the eyepiece. This is especially true for kids' whose legs are shorter and often have to stretch upwards and uncomfortably while trying to see the through the eyepiece. Adults too. Being a teacher is fun!

    Cars, on average, still seat the same number of people, still corner about the same, still accelerate about the same, etc. Computers by comparison are running well over 100x faster when accounting for multiple cores and threads and massively faster clock speeds. They have thousands of times more memory, both RAM and hard drive. GPUs are thousands of times more capable. They can now render near life-like 3-D images in real time at 60 fps or better. By comparison, cars would need to be able to reach 10,000 mph, carry thousands of people, and yet fit compactly in the palm of your hand for storage. So yes, cars have essentially the same performance as 20 years ago when compared to computer performance of the mid-90s.

    Having been brought up to believe that you never view the sun through an optical instrument, at first I was a little sceptical about using anything other than full aperture front end solar filters. Having owned and used a Lunt 1.25" Herschel Wedge for a couple of years now I'm much more comfortable about putting my eye to the eyepiece. I use the wedge with my 100mm, 102mm and 120mm refractors including at outreach events and it works very well. I've very recently acquired a Lunt LS50 H-alpha scope (single stacked) and I'm intending to do more Ha observing next year with this. The initial couple of sessions that I've had with it have been pretty impressive but I'll need to wait and see how deep my interest is in Ha observing before I invest in double stacking it. The prospect of sitting in the sun feeling warm while doing astronomy is getting more appealing as I get older !
