  1. SOLD Selling the filter for 70€ . Original price around 230$ (including shipping, vat and customs). The filter is in excellent condition, used only 3 times. No fingerprints, no scratches no dust (image attached). I will also handle the shipping through my post office without cost. If another shipping method is requested, then we'll have to to discuss the price. Contact me if interested. Clear Skies, Anthony
  2. Hello, I'm selling these 2 filters since I'm getting a mono astro cam. The filters are barely used and in perfect condition, no scratches, no fingerprints, not even dust. They are both amazing filters, probably the best investment I've made. I've attached some images taken with these filters, using a 100$ celestron newtonian, a 250$ Canon 500D and the infamous AVX. Also attached are images of the filters showing their perfect condition. Astronomik CLS-CCD Canon Clip in Filter: https://www.astronomik.com/en/filter-gegen-lichtverschmtzung-filters-against-lightpollution-lpr/cls-ccd-filter/clip-filter-eos-mit-astronomik-cls-ccd.html Original price including VAT is 155 Euros (around USD 182). I got it for around USD230 including VAT, shipping and custom taxes. Selling for USD 100. Astronomik Ha 12nm Canon Clip in Filter: https://www.astronomik.com/en/clip-filter/clip-filter-canon-aps-c/clip-filter-eos-mit-astronomik-h-alpha-ccd-12nm.html Original price including VAT 194 Euros (around USD 228). Got it for around USD 270 including VAT, shipping and custom taxes. Selling for USD 150 I am willing to ship them on my own expense using LibanPost (from Lebanon). Shipping might take time; if you would like to use some other shipment method please contact me to discuss the price. Feel free to buy one or both together. Let me know if you have any questions. You can also contact me on <private email address removed> Cheers, Anthony
  3. Selling the Astronomik 12nm clip in Ha filter for 120€. Bought it for 270 usd including vat, customs and shipping so it's a really good price. The filter is still in excellent condition, used only twice. No fingerprints, no scratches not even dust (image attached). I will also handle the shipping through my post office without cost. If another shipping method is requested, then we'll have to to discuss the price. Contact me if interested. Clear Skies, Anthony
  4. Hi I own a Skywatcher SynScan 130P Explorer but I find it does not take good astro images and now I hardly use it which is really sad and with some money coming in the next few months I want to sell it and buy another good scope to support taking pics of the night sky. Well, my question and I need advice : Since I am really enjoying photographing the night sky at the moment, I am using my Canon 70 D on a good tripod with Samyung 14mm or Tokina 11- 14mm. I have got some ok pics from this of the Milky Way but I am not greatly satisfied with the results much. As an upgrade, I am keen on buying a star tracker and a astro modified camera( or something similar to this ). (I want to kick myself as I sold my Canon 450D two years ago for £100) Do you think I should ? Is this useful ? Can I use the Star tracker with my canon 70D? Also, If I get the star tracker will a astro modified camera help me take better pics. I have seen some stuff on You tube , but I am confused. Also , If I buy another scope will I be able to use the modified camera with that ? Sorry for asking so many questions.
  5. I've recently made myself a 12v to 7.4v battery conversion for my Canon 1000D DSLR Camera. This allows you to power it using a 12v source such as a Skywatcher Powertank/Leisure battery, and ensures there's no need for battery swaps mid-imaging run. If you buy a pre-made one then these are ~£40 from Astronomiser etc.Parts, Tools and Instructions are detailed below.Note: I've put Maplin codes, links and prices for some of the parts for reference, but they can probably be obtained elsewhere cheaper. e.g. eBay, Farnell, RS Components etc.Note 2: This is a guide only and I take no responsibility for people breaking their camera!Parts List:Velleman K1823 1A PSU (Maplin VE58N) £9.99Plastic Enclosure 75x51x25 (Maplin KC92A) £2.9912v Switch (Maplin N84JZ) £1.993mm 12v Red LED (Maplin CJ66W) £0.743mm LED holder (Maplin N85AX) £1.3420mm fuseholder (Maplin CT90X) £1.0520mm fuse 1A (Maplin GJ90X) £0.21TO220 Heatsink (Maplin KU50E) £1.14Canon 1000D LP-E5 Battery (eBay) £2.1912v Cigarette Lighter Plug & Lead (eBay) £2.75Wire ~£0Zip ties ~£0TOTAL: £24.39Tools:Soldering ironSolderGlue gunDrillStanley knifeWirecuttersSmall philips screwdriverMultimeterInstructions:Open K1823 kit and complete using enclosed instructions, apart from lying the large capacitor down on its side - so it fits into the case.Place heatsink onto TM317, will have to bend the component back slightly so it fits in the case.Drill one hole in either end of the plastic enclosure for wires in & out.Make holes in enclosure lid for led holder, fuse holder and switch.Fit items into lid.Cut end off cig plug.Measure & cut wires, solder up according to wiring diagram.Carefully open LP-E5 battery case & remove battery, but retain contacts.

  6. Hi All, I wonder if someone can please help, I'm fairly new to astrophotography and confused about aperture. Basically I'm looking at a Canon EF-S 55-250mm lens. It has the specs f4-f5.6 does this mean that the lowest point of aperture possible is F5.6 or will it go lower. What I find confusing is that I have a lens that's the EF-S 18-55mm lens which has the specs of f/3.5/5.6 however My camera does allow me to set the aperture at f/8 The reason I ask cause it is advised to use a low aperture of f/8 to capture images of the moon. Any help and guidance would be greatly appreciated!

  13. Low shutter count. Have used this camera only twice. Once for andromeda and then for lunar eclipse. Will supply with 2 or prob 3 batteries, whatever i have and charger £200 pp extra
  14. Hi all, new to astronomy. Have bought a Williams 81, canon D450 had it modified. Celestron advance gt mount. I want to use Eos backyard, (apparently it can only use 32 bit as there are no (canon)drivers for 64bit I need to buy a computer to run the above programmes 32/ 64 bit ?haven't a clue what requirements I need.or if a new computer will run it. I also need to buy a Photoshop programme. Think it needs 64 bit to run it Need all to be compatible any help would be appreciated.
  15. After reading the Sony star eater story I abandoned the brand and looking elsewhere. I used to be a nikonian/touched canon bodies only a handful of times but that should not bias my decision for the future. Any arguments for choosing one or the other? In this quick review they came up more or less even. I would like to monochrome-mod the camera and add a cold-finger-type cooling as well. And I know, there are cheaper mono astrocameras, like the asi1600mm-c arund, but that tiny creature covers only 1/4 of the frame of the 6D/D610. Full Frame CCD's are way too expensive for my budget except a few KAI-11002 based 2nd hand unit, but that piece of hardware has so low QE (H-a: 30%) and so high noise, that a microlens-stripped DSLR might fare better... (and still significantly cheaper) From my side: For canon: - I have a sigma ART 1.4/20 for EOS lens, currently used for videography but could make a great timelapser. - Canon has a somewhat shorter flange distance - in case I have space issues, abovementioned review quotes vignetting, due to the smaller throat diameter (nikon: 44, canon 54mm) - this is a topic in my case, I plan to use a Riccardi reducer on my apo scope. -Canon is broadly supported by the astrophoto community, has magic lantern firmware mods (whatever that means for astro...), etc. For nikon: -I do have and will keep my astro-modded D5100 for the time being. This means two sets of adapters.
  16. Attempt number 2 at processing Jupiter. Finding it incredibly frustrating trying to image with my current set up, so have invested in 'Making Every Photon Count' to help me decide what I should upgrade to! Composite image of Jupiter and 3 of its Galilean moons Canon 70d, 8" Dobsonian (prime focus and manually tracked) 1 x 30 sec video, stacked, for Jupiter I attempted eyepiece projection, but couldn't achieve focus... no doubt I am doing something wrong, but couldn't work out what!
  17. Cloud, cloud and more cloud – but looking on the positive side, this presents an opportunity for a ‘project’. Now, I’ve already done the observatory ‘spring clean’ – I even have the photos to prove it – so I thought I’d tackle a project that has been on the back burner for years; auto-focusing my camera lens(s) for wide-field imaging. Despite two attempts at putting the TS Telefokus 105 microfocuser on my Christmas list so that I could accurately focus my Canon 200L telephoto lens on the stars, there were no takers so the project stalled. However, having bought a second motor for my existing autofocus controller to install on a new telescope got me thinking that maybe this would actually be a better way of controlling focus and might even allow autofocus during a long imaging session to compensate for temperature changes. So, I put a third motor on my birthday list and my two sons clubbed together to buy it for me moving the project forwards! Yesterday, I completed it with the addition of a finder-guider that I had in my ‘goodies’ box that is normally used for guiding short focal length review telescopes. Now, in fairness, it is untested on the night sky (cloud, remember, hence the project!) but what I can tell you is that the focuser moves in invisible increments or quickly as required, is ultra smooth and shows no sign of slipping! Unfortunately, much as I’d love to, I can’t install my mono camera as, with its built in filter wheel and OAG, there is insufficient back-focus. This means that the system will be used with my OSC SXVF-M25C coupled to the Canon 200 L lens using a custom adaptor I had made when Adam was a lad. What could possibly go wrong? Front View The two pictures above show the 72mm lens has been stooped down to 52mm using a step-down ring. This reduces the aperture from f2.8 to f3.8 to improve star shapes at the periphery of the FOV but without adding the diffraction spikes that would be a feature of stopping the lens down using the iris.

  18. Hi I have a Sky-Watcher telescope, model AC 120/600 Startravel BD AZ-3 that I want to use to take photographies. This one: http://www.astroshop.eu/skywatcher-telescope-ac-120-600-startravel-bd-az-3/p,16710 I have an "old"(2009 model) Nikon D3100 camera and a t-ring, but the thing is that my camera won't read the t-ring. I read online that it's too old to be compatible with a t-ring. So I wondered if anyone knows about any camera models I can use? I'm thinking about getting a new camera because of this and I would like some recommendations. Which cameras do you know are able to "read" a t-ring? I would prefer the cheapest models Thank you for your time
  19. So far in this and many other hobbies I have made the same mistake going entry-level and then lost money in the long run when upgrading. I already subscribed to Nikon a long time ago so have a bag full of Nikon for normal photography but what I think I want (based on support) is a Canon body that I get modified to stick onto the scope. I have seen some amazing photos taken with entry level cameras like the 300d, 450d and 1100d so what I would like to know is, other than megapixel, what would be the gain in going for a better camera than say a used 1100d? Thanks
  20. Hi guys, Just a little advice required please. Wanting to try imaging with a dslr. I have the opportunity to snag a mint Canon 50d for a few hundred pounds, 2 batteries, all leads, and original discs and box. Firstly are these used widely in AP and secondly is this a good deal? Feedback and comments welcome.
  21. COMET C/2014 E2 JACQUES Meets the OPEN CLUSTER NGC 609 23 / 08 / 2014This is my first attempt at a Comet. After having various issues with stacking and a rogue stretched star as a result of a stacking error. I can finally feel proud after relentless hours spent at stacking and re-stacking this image. I feel proud I managed to process this Comet as well as it looks. I think there is a hint of a tail at the 3 O'clock position but who knows... The bonus is the comet is above an Open Cluster NGC 609 which adds more interest. Conditions were good and if I had set-up the Mount better I may have managed longer subs. There is a hint of star trails due to wind and tracking issues.16 x 30 secs Light Frames30 x 30 secs Dark FramesISO 800Skywatcher 200P 8" 1000mm ReflectorEQ5Canon 1100D ModdedBaader MKIII MPCC + Hutech IDAS LPS-D1 FilterHI-RES IMAGE:
  22. Hello everyone, Last wednesday, I tried my first shot with an Astrotrac, which I borrowed from a friend before making the jump and buy one. And I must say that I'm quite amazed by its tracking capabilities, even without an autoguider. I know that the lens I used has only 85mm of focal length, but I only got a 5 pixels drift during 45 minutes of imaging : that's quite impressive Enough chitchat, here are the images : 5DmkII, Astrotrac, 85mm f/4.0, ISO 800, 14 x 60 seconds exposures, 15 darks, 50 bias, no flats, PixInsight for everything except the colors/saturation. From the Southern Cross to Eta Carina 5DmkII, Astrotrac, 85mm f/2.8, ISO 800, 9 x 60 seconds exposures, 15 darks, 50 bias, no flats, PixInsight for everything except the colors/saturation. Pipe, Trifid and Lagon nebulas, with some Barnard 5DmkII, Astrotrac, 85mm f/2.8, ISO 800, 30 x 60 seconds exposures, 15 darks, 50 bias, no flats, PixInsight for everything except the colors/saturation. Rho Ophiuchi A mosaic of the last two images Click on the pictures for a larger version I hope you liked them ! And if you're on the fence to buy an Astrotrac, just do it, it's an excellent piece of gear. Clear Skies
  23. This is a very wide angle image of the Night Sky looking east toward Norwich (hence the orange glow) Unfortunately i forgot to take it in RAW so there is a bit of noise evident I used the wide end of a Sigma 10-20mm EX lens on a Canon EOS 60D
  24. Canon 450D Modified for astrophotography, the IR cut filter has been removed for better response on red emission nebula in deep sky objects. Comes with battery, and charger. Shutter count is (atm) 5914, see picture 4. The camera is in great condition, throughout. No lens, just body. Will post special delivery. message me if you have any questions. Price is £150.
