    Hi everyone I saw a cheap 'Russian' -it says USSR on the lens ring- 300mm lens on eBay for €50. Just for curiosity I took this snap, never expecting anything like. I was surprised at the colour and corner correction it gave. It would be a great way to make a start in ap with a dslr; my Canon kit lens comes nowhere close. Interesting... 700d: 90 minutes @ ISO800

    This is one of my favorite regions of the moon, every time i keep imaging this region over and over again. This is an old image was taken last year.

    Heya, It was raining all morning with total cloud cover. Went to town and ran errands instead. But, to my surprise, around noon, the sky cleared up and seeing was pretty good. Managed to get some data on AR2733, it's starting to calm down and the umbra are fading, but the plage is still large and there's activity going on. There's some rather nice prominences around the limb, but one particularly interesting one making a show.

    Composition of 3 exposures to recover Highlights and shadow, not really the best source files as I was not planning on doing HDR but just finding the wright exposure time, thanks to LR I was able to recover some detail in Highlights and Shadows. Moon-HDR version by Yves, on Flickr

    Its been a pretty barren last month, what with the weather and the festive duties. Captured at 09:00 low over the roof tops. Not the best conditions, not helped imaging through a neighbour's boiler smoke, very little detail visible. C9.25/Asi290mm & Baader UV filter.

    fighting loads of cloud here today so only short vids to work with, theres ooodels of photoshop with the AR shot. kit starwave 102, quark, asi120mc. wishing you all better skys than me. thanks for looking. charl. AR2733. don't know if this is any better. ive restaxed after removing most of the frames with cloud in that's got rid of most of the artifacts but ive lost some detail, I think its one of those shot which is a none win .

    I made a decision to do some financial investment with FLO after noting recommendations and advice from your goodselves. The major one was the mount a HEQ5 pro with the Rowen Belt Mod and learning EQMOD I got a EOS 450D modded by the astronomiser and invested in a polemaster Previously i used a Wifi Discovery mount Anyway for me it all came together this week this is the difference about £1500 has got me and 4 months of effort The ST120 and 450D are common only will try the ED72 next Its been a frustrating journey what with our weather and gear that works in the house but then decides to act up when taken outside Anyway here is proof of my efforts

    Hi. Managed a short session on M1 the other night.This is an RGB image,as the moon was too bright for a Luminance. Taken with a ED80 and a Atik 314L+. The sum of 12 x600 secs for the R/B and 12x 500 secs for the green. Calibrated with darks/bias and flats. Cheers. Mick.

    Have you ever wondered what a hi-resolution image of a volatile star like the red super-giant star Betelgeuse looks like? Well you don't have to wonder anymore...here you go...> https://www.inverse.com/article/33408-supergiant-star-betelgeuse-is-bulging Your comments are welcome.... P.S.

    Unfortunately, the January cold snap and its freezing transparent skies coincided with the full moon. Fortunately, Orion is filled with double star beauties, which kept me enthralled for three consecutive nights. Everyone knows the biggest attraction- the Trapezium. I quickly reaquainted myself with the E star and had a long look for the elusive F. On the second night my head jolted a couple of times as I seemed to catch it for a moment and the next night I had it for sure. I found it interesting how your brain seems to have a memory for sights that makes it so much easier to see a faint target subsequent times. Once I've seen something, it's often waiting for me the next time, conditions allowing. Rigel was wonderful. Sigma Ori gave up its fourth star easily as I'd done the hard work last year. Iota Ori, Meissa and Alnitak are wonderful too (Alnitak showing a difference in colour). I was given some advice on new ones (for me) and I find the first time more thrilling and more of a challenge. Eta Ori was a surprise as I expected a tight double but the companion wasn't close at x112.5 but it was very faint. Psi Ori was another fine one which looked single at x90 but was split at x112 (I might have it confused with 32 Ori. And one or two failures such as 52 Ori. On the second day I was so awestruck by the transparency that I spent about 20 minutes trying to split Sirius at x90. Later research revealed that I was wasting my energy although I enjoyed it so much I can't say I was wasting my time. Anyway, on a less than dark night, Sirius is a good place to hop from to find Beta Mon, which is another beauty. All in all, a wonderful night leaving me with a sense of accomplishment and a peace, which has helped a lot in what has been a trying week. If I could take one piece of stargazing wisdom from these sessions it would be- a blanket for your knees can be more important than an extra eyepiece. Thanks for reading. Dominic

    Some really colourful red carbon stars around just now. I was lucky enough to get a gap in the clouds , very surprised at how bright and red UU Aurigae looked . Some of these are greatly variable , reports of "Hind's crimson " ( aka "Vampire "star) for example ,depend on catching them bright. I've shown these as show stoppers from being a "wow !" to "where is it ?" Small aperture helps in seeing colour as does , clear skies ! Nick.

    It’s been almost a year since I came here looking for help to buy my wife a scope as a birthday present. At the time I had zero interest in photography or astronomy but a lot has happened since so I though it would be fun to come back and report. So I ended up buying her a small SCT and then using the scope more than her, while trying to help her set it up I happened to see Orion through the eyepiece. Then I tried to photograph it and then I got hooked on this hobby. I’ve since bought a new scope/complete setup and for almost a year now I’ve been out in my back yard all night every night when it’s not cloudy. im now using a 100mm refractor, an EQ Mount, a ZWO astrophotography camera, a guide scope, guide camera and just yesterday I got a auto focuser and I also write my name on my photos now ??? I’ve learnt a hell of a lot in a year but continue to know very little. I spent most of last night trying to get my focuser to work. having said that over the past year, I have managed a few images that I’m proud of. Here is a couple of them as well as my rig and that first dso image from April last year as a comparison.

    I would class this as transportable. Portable , to me, suggests being able to carry the telescope complete. ?

    PM me your address. I'll send you my 8mm BST Starguider that is redundant in my collection (it's kind of new - a customer return from skiesthelimit - I bid on it on ebay a few weeks ago ). I will gladly help you out - nice to see young people getting interest in astronomy! x150 will be well worth it. x300 depends on your telescope - aha I see 8in dob - x300 might be useful sometimes.

    Excerpt from Burnham's Celestial Handbook, with a mention of "a stain of fog" resembling "a breath on a mirror", interesting comparison with breath on an eyepiece lens, but also the fact it can be seen with only 2 inches of aperture. So there's nothing difficult in believing you saw it with your 8-inch dob, Alan. Another interesting point is it disappears when the scope is too large (18-inch Dearborn refractor), surely because glare from the star becomes too strong.

    Have just got myself a TV Powermate to use for planetary imaging - managed to ave a first run on the day after it arrived (!). Typically just after full moon, so had to go skirting down the western limb - Petavius and Langrenus. The seeing deteriorated a bit after Petavius but fairly happy with the result. 350mm f4.53 newt, TV Powermate 2x, ASI-120MM, best 5% of 7000 frames. Petavius Langrenus

    Shane has passed on it bud, so you are welcome to take it. My partner recently got me the 5th Edition as a surprise gift (she hadn't got a clue I already had this) so you are very welcome to it. Great book and I'd rather give to to another Astronomy enthusiast than sell it. Inbox me your address Only issue is I cannot mail until Mon / Tues due to an incredibly busy work schedule this weekend (I work very long unsociable hours). And that's cool, if you want to make a donation to a charity of your choice, then great Cheers Richard

    Hi Richard such a kind offer. My sessions are so time limited (usually an hour or so after school) that I'd probably not make best use of it and tend to use star maps with them like road maps. Let someone else benefit from your kindness this time and thank you again ?

    I had some fun a couple of weeks ago when I had the briefest of clear skies in south Devon and could power-up my home observatory. The following image only comprises 30s and 10s subs and shows that the good old KAF8300 is not quite 'old' technology yet . . . . only having a bit of fun here ? . . . not meaning to start a CCD vs CMOS thread ?. Each LRGB channel - 60 x 30s and 30 x 10s - with the aim to reveal some of the core without too much complication or fuss and straightforward processing. Taken with my WO FLT132 at F7, QSI683 and Astrodon filters. cropped circa 10%. The bright targets do offer some opportunity to keep us sane. CS . . . eventually? Barry

    JOC, I have the Morpheus 6.5mm and I would have to say it is my favourite eyepiece for high power viewing, spectacular views of the planets! Meanwhile, I had a delivery of my own today, and I'm just a little excited, as I'm in the midst of being determined (and thwarted) to see Barnard 33, the HorseHead Nebula, so this little gem should give me my best chance so far..... .....but of course the clear weather of the last 300 or so weeks has now turned to cloud.......?

    I guess I would be totally out of imaging at the moment if I didn´t have my 3 nm Astrodon Ha-filter. First clear nights in over 2 months and of course that darn evil orb is up there, bright as ever! ? Managed to get a total of 76*5 minutes and I guess this is about as good as I can get it considering the full moon. Really can´t wait to get my hands on some O3 and S2 data for this one now! Oh, if only I could afford Astrodons for those as well... The field of view of my Sigma 500mm lens really fits this target! Thanks for watching, hope you like it ?

    Hi everyone. I've been an astronomy nut for ages but finally got a telescope this Christmas just gone. A basic Celestron Astromaster 130eq with the lens kit and a mobile phone mount. I suspect there are a lot of answers to my questions on here so I will do some searches and see what I can find. My main clear photo is of course the moon taken on my Samsung galaxy S8 using a 15mm lens on the celestron. I will attempt more shots of other objects. Currently here in Australia, Jupiter and Venus are up around 4am in the east so there is a lot of light polution coming from Sydney and that's the other photo Jupiter and 4 moons.

    Mark it doesn't surprise me that you see it in the 12" newt- I was observing the Pleiades last night with my 15" f4.8 and the view of the Merope was VG. Your 12" gives image scale to pull the Merope "fan" out- under very clear dark skies the extent of the nebulosity grows and this gives smaller scopes a very nice opportunity like the H130. It is a myth that larger scopes don't work on the Merope, but if the TFOV is too narrow we might "look through it". Under dark transparent skies the H130 is superb on the Pleiades nebulosity complex with a 24 ES 68. For reference my conditions last night was -32c, 21.4 mag skies with a fine high haze of suspended ice crystals. These conditions lowered my sky darkness but also provided "holes" of extremely good transparency. Also of note the the Horse Head was visible with no filter in the 15"/ 30 ES 82, 20mm Lunt but disappeared in the 17 Nikon HW- too dark.

    One interesting aspect of observing faint objects is that they are often so easy to detect after you see them the first time. In my experience, the nebulosity around M45 has always proved impossible. That said, the comment from Burnham above is perhaps important as I generally observe from dark skies with my 16" dob. The only time I felt I was 'seeing something' was with a 100mm f7 ED frac from the same site. Maybe I was! I'll certainly return to this object on a regular basis anyway as it's so lovely.

    Thanks Shane, I always make sure when recording sightings of objects, as you rightly say there is no point in observing otherwise. This hobby isn't a competition but an exploration of the sky and it's treasures. Returning to objects for a second/third or more view has always been part of my routine.

    I've tried for decades to see nebulosity around Merope visually and failed ,and I stay in a fairly dark site. Their has been times I think I've seen it but I think the best practice is that if your unsure about an observation it is to best to discount it.

    In Nov 2014 we went to Iceland hoping to see the northern lights. An utterly amazing country but all we saw was cloud so our first trip was an aurora failure. We returned to Iceland at the end of Nov this year and were greeted by 40mph winds and a resulting wind chill of -18! However, the skies were clear so aurora watch was on. We saw the faintest hint of aurora on night 1 but the wind was brutal so it was impossible to stay out for long. On night 2 the aurora was far more active, the wind slightly lower but there was high level cloud. We still spent hours enduring the wind amazed at the dim, but dancing lights above us. Everything changed on night 3. Night 3 was completely clear and the wind had dropped substantially. The aurora came out to play properly... This is a single 6s exposure on a 6D with the Irix 15mm @F4 and ISO 3200. Almost no processing in Lightroom beyond lens correction and a hint of noise reduction. The Aurora is such a strange phenomenon and so dynamic that normal astro processing doesnt seem to work! I have a load of other images and some timelapse that I will also share when I have managed to process it...

    Hi Alan, If you keep on observing the Pleiades for an extended period, you may notice the nebulosity extend beyond the cluster. Sometimes it becomes more obvious if you gently nudge the scope which may help you to detect subtle nebulosity away from the stars themselves. You might also like to check stars around the pole which you'll likely find do not show the nebulous glow around them. Good dark adaption works wonders, so try to keep stray light from your local surroundings from catching your eye. I use a black blanket to cover my head and focuser, and spend quite some time on each object so I can really study what my little scope is capable of revealing.

    Hey guys! I have just tried out my new dslr camera on my SLT 130 Telescope. This image of the Carina Nebula consists of 44x30s subs at iso 1600. This was stacked with 15 dark frames. I might add an extra hour of data and some flats tomorrow to see how it will turn out. I tried my best in processing with gimp as this is my first ever dslr exposure of a dso and I plan to take some better images in the future.

    Yep, the Japanese made version (the Series 4000) was the one to get. It goes for over $100 used here in the states. Notice the difference in the eyecup. Besides the Japan label, it's the easiest way to distinguish it from the Chinese made version.

    I've just unpacked this: I couldn't resist. The trouble is the 'collection' now looks like this: I kind of now feel the need to continue until it's complete ("Ouch!" says the bank balance), perhaps if I do so I'll sell off some of the other 'old friends'. Possibly, maybe.......
