    As the subject states; a 6 pane mosaic of a part of the Orion constellation. 2x3 Mosaic 3h per pane for 18h total This is not complete as the goal is to finish the entire constellation in Ha and Lum (cover the Witch Head). As always please comment on where you think improvements could be made and if you know how, please state how to do so. It not only benefits me, but the entire community. Thank you very much for looking. Small: Large: Of course I catch a couple of errors after uploading and typing this out ... ack. Ah well

    My collection of targets over three imaging sessions getting to grips with the Atik & Frac etc. I seem to have the correct spacing now for the flattener, maybe a little tweak in one corner, guiding is now a joy going through the handset instead of the ST-4, tweaked balancing & fathomed out where to place the weight depending on where i am imaging. Most of these test images to see how things went & i appreciate they are not that good, most need a lot more data, it would seem my rig is now tamed. The Lunar shot was a stack of 80 x 0.001 sec subs from 300 using the Atik & AA, i was waiting for the Horsehead to come into view & was curious to see what would happen, filters were Ha 7 & UHC (don't ask ) Thanks for looking

    6x120s and 6x20s (core) luminance and 6x60s RGB with 6x20s for the core. Processing with Pixinsight using bias and flats but no darks. This target was almost an afterthought whilst thinking about packing up for the night, I saw orion and thought, heck, why not! Tony

    I was a bit poorly last night and it was quite misty / lightly clouded, but I thought I'd pop out briefly with my grab-and-go undriven kit to nab this image of the moon with my ED80. Please click image for (slightly) higher res. I used my 7nm H-a filter to try to cut through the light cloud/mist and stacked about 1100 out of 1700 frames, which seemed like a high percentage, but the quality graph looked good in Autostakkert, as it normally seems to do with the H-a filter shots. And here's my attempt at an inversion: Please click image for (slightly) higher res. --- 15/11/2013 Celestron Onyx 80mm / Grasshopper 3 (ICX687) / 7nm H-a filter

    Would've just edited the other thread's title to let folks know I'd posted an upscaled image (a repro - for better or for worse ) but once you make an initial edit to any first-post like I did beforehand for some typos, I can't seem to find an edit button..?!? Anyway, here it is.....I must load my spare copy of CS4 onto this laptop...but then again I must stop using it for processing full-stop - but it's a tad difficult not to when you're 6000km from home!

    Using HA and OIII filter on a Atik 314L+ 15x600s subs of each i got this image last tuesday as myself and my friend tried out her new scope a Pentax 75mm. any comments welcome as i'm just getting into bi-colour imaging. thanks for looking glen

    Morning all, Luckily my two weeks holidays have coincided with at least a couple of moonless clear nights, and I've spent that time dedicated to the tadpoles. Last nights clear spell was meant to break double figures in exposure time, but wasn't as good as predicted with milky cloudy spoiling things. Exposure time stands at 8 hours so far, imaged using my Altair Astro 6" RC, Astrondon narrowband filters and Atik 314l+. Processed in Pixinsight and CS5. The colour version has a standard colour map of Ha to Red, and OIII to Blue and Green. Hope you like them, here is the colour version........ And the Ha mono......... Thanks for looking

    We've had a couple of clear nights over the past week here in Oxfordshire and I've spent the time getting some data on Sh2-171 in Cepheus. I've had real trouble with this. After a[nother] strip down and rebuild of my mount, my guiding has got worse - still working on that - so I've been strict and tossed have the subs. And then the processing. Seems a tough target because there is Ha right across the frame but I've found the [OIII] and [sII] to be really faint. I've tried this in the HST palette but it doesn't really do it for me - the Ha in the background is responsible for the 'orrible brown everywhere. Ditto the CHFT (which I'm not even bothering to post) and I think I prefer the bicolour version. Scope: Takahashi FSQ85EDX Mount: CGEM DX Camera: Atik 490ex Guiding: Atik OAG; PHD; IMG0H Data: Ha - 11 x 1200s; [OIII] - 11 x 1200s [sII] - 9 x 1200s

    Going through my data on M44 I thought I would try and label some of the interesting stuff. As well as doubles, multiples, variables there is a Blue Straggler. Anyway here is a cropped image of the Beehive with hopefully the right labels. I pulled data from the Aladin app/Simbad and WDS so if anything is amiss thats where it originated. Data from SW 80ED Pro+reducer+Hutech LP filter........Canon 60Da........1x 16secs@ISO 800

    Honestly, I can't believe the mentality of some people. cry and throw a wobbly when s@n might get canned then when it's declared safe for another year or two it's straight back to moaning about the format and presenters. just curious....why did you want it saved? I sometimes wonder if they are waiting for spm2 to come along and buy the house so all can "get back to normal". It ain't gonna happen so get over it. And Paul, did your mother also tell you to make so many insinuations that there is no doubt what-so-ever that you are casting aspersions about John C. without actually having the courage to name names? Dave-T, Sorry, but if approx. 3-4 mins impersonations in 12 mths is too much (impersonations endorsed by spm), then perhaps it's time to change the channel. As an enthusiastic amateur, I wish him all the best.

    Took this the other night/morning,first time I've imaged this and really pleased with it.Taken with a 200P on an EQ5/AstroEQ,modified Canon350D with a 1.25" Castell UHC filter(for the light pollution)21 x 120 sec subs at ISO1600,processed through CS5 by Mark,cheers once again. Didn't realise how bright the core was so had to 'borrow' a few subs off QM to get some detail in the core

    Really interesting thread, thank you for asking that question! Purely by coincidence I was trying to manually track a few aircraft today with my refractor, purely practice, to get ready at capturing the ISS or for that matter anything else in close orbit. Today has been clear and bright and I had some success, might have to get around to trying to photo capture some of the planes in detail, perfect practice, and sounds quite a challenge. They are in close orbit after all What would cruising altitude be btw? Is there a way to determine this with any accuracy?

    the only rule is the one you set yourself. this will be based on budget really. if you can afford to buy the very best eyepieces and want them then go for it. I have a couple of eyepieces each worth more than three of my four scopes. I have a range of eyepieces from very cheap (<£50) to very expensive (£400+) and enjoy them all.

    Later on last night the skies cleared so I decided to have a go at M42 unguided. Being low in the sky, and without finished PA, longer subs produced star trailing so I limited it to one minute subs. In the end the cloud came back and I only managed about 10 subs each of Ha, OIII and SII. Here's the result then of 11 x 1m Ha, 10 x 1m OIII, 10 x 1m SII all unbinned. Stacked in DSS, stretched in Ps, aligned with Registar and the rest in Ps. SII -> Red, Ha -> Green, OIII -> Blue. Histograms balanced and Selective Colour applied to give the Hubble palette. Noel's Actions were used profusely to reduce the stars, enhance the DSO, sharpen and reduce noise. Selective Colour used to kill the magental in the stars as far as possible. The image was cropped to just the centre part with just under 1200 pixels wide for uploading here - there was no resizing so it's pixel for pixel. Saved as PNG for optimum results. Considering the defective telescope, short exposures only - no long ones to catch the fainter stuff etc. I don't think this is too bad. Bright moon too. EDIT... Well it looked a lot better in Ps

    I find that like the moon if you just allow your eyes time to adjust then the detail starts to appear as your pupil shrinks. to start to see real detail I find about half an hour of continued viewing works best on Jupiter.

    you have an f13 scope which means it doesn't need the more expensive and better corrected eyepieces that faster scopes need to get the best out of them. Pretty much all eyepieces are good on axis what you pay for is for them to be good off axis as well. the wider the view the more you pay for that view to be sharp to the edge and the faster the scope the more you need expensive eye pieces to be sharp to the edge. the 127 isn't a particularly wide fov anyway so expensive wide angle eyepieces would be a bit of a waste a good eyepiece like the bst starguiders or baader hyperions will be great in those. Unless I was looking to upgrade my scope I wouldn't be looking at any eyepiece above the £100 mark as I wouldn't see the need there are plenty of eyepieces between 50 and £100 that will perform brilliantly in that scope and should be sharp to the edge

    I have just bought one on ebay (a CF-29 which is the fully ruggidised version) for £99 delivered, which is a lot cheaper than most netbooks.

    You need to match your eyepiece to the capability of the scope. Some people advise getting some decent eyepieces now for beginer scopes, then you can use them later on when you upgrade. I prefer to take the weakest link out of my current gear to make it usable. I don't need to future proof it. The Revelation Plossls I am using at the moment have come down to £22 each, and they work fine in both scopes. I have £60 Maxvisions which are well suited to the 200P, but would be wasted on the 700/76 3"beginers scope. It's hourses for courses. A £250 to £500 TeleVue Eyepiece would be of very limited value to me. I am a recreational observer, and I would struggle to justify the cost. Of course I am free to change my mind if the equipment, my free time, or my obseving habits change.

    Good decision. Still thinking aloud, what about defective edge blackening of the lenses? Like you I like to get to the bottom of these things. Olly

    Findings from my testing and observations :- There are no reflecting surfaces within the light path. There are no intrusions into the light path. The filter wheel and adapters with 460EX camera have been used with other scopes and also with lenses and apart from irises in the lenses when stopped down, there's no problem. When the scope is stopped down from 80mm to 60mm with an aperture mask in front of the lens assembly the problem disappears.The conclusion from 1. 2. and 3. is that the problem lies with the telescope. No. 4 indicates that this is probably caused by some problem with the lens system. Without actually dismantling the lens unit there is no way of telling what. I could mess about with aperture masks and find out how much aperture reduction is required to cure the problem. But what help would that information really be? I guess if it were to turn out that a 79mm aperture mask cures it, that would be very little change in focal ratio and would render this particular telescope useable. But would even a slight stopping down at that position upset the optical design? I think it could well do. The bottom line is "Am I happy to go on messing about, spending time and effort on a long shot?" No I am not. The conclusion then after weighing up all the probabilities is that I will ask FLO for a replacement telescope. I am satisfied - quite happy in fact - that this model of scope will provide what I want and therefore a replacement is my choice. I would like to thank Steve for his patience in this matter

    I'm not immune to 'equipment fever' but do try to keep a check on my actions. Obviously, if one has the wage to spend, and isn't compromising their family, or growing debt etc, then it's a different ball game but for myself I try to keep to a few general rules. If I want something, I will save for it whether I have the money in the bank or not. That way, I avoid impulse buying and have plenty of time to build up my expectations. It often occurs that a few months down the line, I no longer desire that something, or now realise a better plan of action.I avoid using credit cards and putting myself in debt. A credit card does not mean free money. You have to pay back what you spend and you will be charged interest on any outstanding balance. For numerous normative reasons, I feel we ought to adapt ourselves to the mental and emotional effort required to get to the point where we can buy something debt-free, rather than the aggravation of dealing with debt and financial stress. A little put by each month and you're a freer woman or man than the other at the whip and call of financial institutions.I try to work with my gear before 'upgrading' on it. I figure each session of astronomy is an arbitrary €1.50 on everything I use. If my EP costs €300, for example, I will need about 200 astro sessions with that given EP (regardless of the time used with it) before I even contemplate an upgrade.Finally, once the money is saved I will try to sit out and wait to see if that something crops up secondhand. I may have to wait a month or two before it does. Other times nothing appears and I will have to buy new.These are just some ideas, but they may help.

    Hi guys, Here's another of the Kalahari Desert fruit, which has been awaiting processing since our travel to Namibia in May. I am time and again astonished at the delicacy of details that the Veloce RH 200 and STL 11K bring about, in both dark and bright nebulae alike. The overall view reminded me about the Biblical story about Jacob's ladder - hence the name. The full verse is on my site :-) I have posted two versions: A non-annotated version: http://www.pbase.com/boren/image/153191210/original and an annotated version: http://www.pbase.com/boren/image/153191208/original I hope you like it, and as always, any comments are more than welcome. Best, Harel

    I can't believe it's been a week since i first arrived at the star camp.... It was a brilliant weekend!! Wish I'd arrived on the Wednesday now looking at you image of the Zodiacal Light Mike... absolutely stunning!! Thanks to Steve for organising the event and to Lesely & Ralph for all they do and for the use of their amazing campsite!! As others have said it was great to catch up with all the regulars and to meet a fair few new attendee's, there's too many to mention by name as I'd be here all night...... but this event just gets better every time and it's down to all the folks that attend!! I thought I'd post up my Jupiter shot from the early hours of the Sunday morning, I managed to capture 4 10k frame AVI's with the colour DFK, unfortunately the one with the best 'seeing' was badly overexposed so I ended up having to chop it to 3k frames - this is the best 1k frames stacked. Not my best effort but I'm fairly pleased and I did say I'd post up the results.... Jupiter from Galloway Star Camp by stev74, on Flickr Re-size Jupiter from Galloway Star Camp by stev74, on Flickr

    Okeydokey good to know that I won't be an outcast here . Usually cruising altitude is about 8-10 kilometers. I use www.flightradar24.com - well known site for most airplane's tracking. You can even see private and military craft - thanks to that I was able to spot and photo two italian air force's 767 and I seen one later at RIAT If you manage to take any pictures, please feel free to share them with me .

    I live at a very dark site. M33 is easier in a sense. I can straightforwardly see it in a little 50mm finderscope. (I cannot see it naked eye, personally, though I believe some can do so.) However, moving from finder to 20 inch I have to say I'm disappointed. It becomes bigger, obviously, but remains 'soft.' Nothing much happens. Now M101's nucleus can be 'sensed' in th 50mm finder. I know it's true because when I 'sense' it and go to the main scope it's bang in the middle. However, when it is high in the sky M101 is far from disappointing. Spiral structure shows pretty well and, best of all, the bright patches at the ends of two spiral arms really pop at a great distance from the core. So my take is: M33 easier to detect but far harder to see well enough for real excitement to set in. M101 is harder at first but more exciting once you get your eye in. Olly

    agreed - my post was suposed to be a bit tongue in cheek. Hyperstar looks to be a nightmare even for experieced people. as a beginner scope it would not be funny i would imagine. Gene, do what Olly says and look at the signatures of peoples kit in the imaging forum. BIG accurate mounts and little expensive triplets with whizz-bang guiding. But at least with a big mount, you can then hang a decent aperture sct off it for visual stuff when you;re bored of staring at laptops.
