  1. The Moon, 21 Apr 2018

    hi guys All my lunar imaging has usually been done with DSLR camera and telephoto lenses, usually the Canon 100-400mm and a x2 teleconverter Last nite I finally fired up the new scope and did some imaging Skywatcher 120mm x 1000mm fl EVOSTAR Black Diamond The mount is a HEQ5 PRO so for the first lunar image through that scope with a ASI1600MM camera and Sharpcap capture software Dave
  2. NEQ6 polar scope

    NEQ6 polar scope, may also fit the HEQ5 according to several retailers. I'd like £20 for this plus £2.95 for RM Second Class postage. Payment by paypal only. This is also advertised on astrobuysell.
  3. As per the title I am looking for a Skywatcher Startravel 80mm or 102mm optical tube assembly, needed for a project. Cash waiting for a sensibly priced example in good order.
  4. Hi, I bougth a skywatcher skyliner 200p (a newtonian dobsonian telescope) and I should receive it in 2 weeks. Since I know nothing yet of the practicalities of astronomy I wonder what accessories I should get initially for it if any. I would love to hear your advice. Collimation : From what I gathered, collimation seems a necessary thing to perform, even with new telescope, right? I read a lot of good and bad thing about laser and only good thing about cheshire. Since I ll be alone operating the telescope, which one should I get if any ? a cheshire like this one https://www.ebay.co.uk/itm/Ascension-1-25-Short-Cheshire-Collimation-Eyepiece-UK/322431518490?hash=item4b126a871a:g:VYkAAOSwWxNYrXEi or a laser (in which case which one would you recommend )? Any resources on how to perform collimation. That sounds a bit scary Finders: I heard a lot about telrad and I am considering one is a rigel quickfinder similar or better ? (https://www.firstlightoptics.com/finders/rigel-quikfinder-compact-reflex-sight.html) Can these be installed without hassle on my skywatcher ? I also heard that the default straight finder installed on the skywatcher is not very nice to use as you need to bend yourself (and the image is inverted) Should I get a right angle one like : https://www.firstlightoptics.com/finders/skywatcher-9x50-right-angled-erecting-finderscope.html How would I install it? Is it as simple as replacing the straight one ? precise finding In order to find objects in the sky, I though first to buy a push to telescope like the orion xt8i but because of the price, I decided to go with the simple skywatcher skyliner 200p. This now means I have to learn to navigate in the sky, which is probably a good thing anyway. Finders helps here but to be precise, I thought about "setting circles" and inclinationmeters but these would require some time to built it and attach it. What do you think? Any good resources ? Probably something I can reconsider later? I might instead try the "skeye" app (https://play.google.com/store/apps/details?id=com.lavadip.skeye) but I ll need to find a way to fix my phone on the telescope. Protection / care: Is there any precaution I should take when storing my telescope (while not in use)? Any useful accessories ? Filters: Since the moon is such easy target and fascinating on its own. should I get a moon filter ? What about planetary filter, are they worth it ? Any other thing I should consider getting ? Any recommended books ? Cheers Ronan
  5. Hello, This is my first astrophotography with my own scope (and first light for this scope). I've always been fascinated with this galaxy, and it was my childhood dream to capture it. It finally happened ;-) You'll find all the technical details on the description on flickr. Overall it's the first light of my skywatcher Quattro 250mm/1000mm f4, NEQ6, with an unmodded Canon 6D. Integration time: 1h59 Processed with PixInsight. link to flickr for the full resolution and description:

Powertank was bought at christmas and has only been charged once The star diagonal got dropped and the silver insert (the bit that you put the eyepiece into) that screws into it became slightly loose in the threads so I repaired it by putting superglue on the threads and screwing it back in. It is held solid now and no glue is visible and all the eyepieces fit perfectly. All instruction manuals and tools still in bag. Non Smoking Household £400 ono reduced Location Bolton, North West England. Collection or I can do local delivery in person. I would prefer this as postage would be expensive also the risk of damage in transit. If needed then I estimate around £15 due to size and amount of items if sent by courier.
  7. skywatcher 127 mak

    Hello there! If someone has a 127 mak, in great condition (and reasonable price), that doesn't use/want anymore, (and he's/she's willing to post to Europe, at buyer's cost) can surely drop me a message! thanks!!!
  8. Hello! i am being offered this 100ED at a price which is hard to resist by an acquaintance who inherited it and doesn't plan on "checking out galaxies" as he put it LOL, it looks like a well built scope and a good frac is a scope for life, anyone have/had this scope? thx!

The scope can be assembled and disassembled in about 10 minutes or so. £1250 Buyer collects. Nottingham Area. Thanks EDIT: Decided to put a reason why I am selling this scope. It's been a fabulous scope (some of you folks may have seen it at the last SGL star party). But fitting this and my 11" sct in the car is a massive squeeze (I did have a 9.25 at SGL and just managed it, with the tents and stuff). So I have decided regrettably to sell. More images can be arranged, and by all means come and view it (no obligation).
  10. Hello, after deciding on getting a dobsonian either a 150p or 200p I was wondering if anyone leaves their dobsonian outside?. Obviously I won’t be leaving it uncovered, I was hoping if there are any special all weather covers? So I can just leave it all assembled.I do have some room left in my garage but might be a tight fit . I was also thinking of getting a bag like this ( something a bit bigger) http://www.ikea.com/gb/en/products/textiles-rugs/outdoor-textiles/tosterö-storage-bag-for-cushions-black-art-20292328/?cid=gb|ps|pla||||. I’d wrap it up in dust sheets or something as well. I really want to get one of those dobs but I’m struggling on where I can store it. And please would someone confirm the weights for me Ive seen the 150p dob is about 7kg is and the 200p is about 9kg and the base being around 10kg for both is this correct?
  11. I have just bought (I bought it in January and the 'scope just arrived today) a Skywatcher Startravel 120mm Refractor together with an AZ5 Mount & Portable Tripod as a Grab & Go Telescope. The problem is that I am really struggling to find a decent quality storage/transport bag or hard case that will fit it. Not to mention the AZ5 and the tripod! I mistakenly bought one of the Geoptik bags for what turned out to be the wrong mount but I'm making it work by putting the mount in its cardboard box together with the extension and the flexible slow mo controls in their boxes to fill out the case and that'll do for now. The telescope however is a chunky beast (to which I added a Finder scope, not fond of red dot sight) and I am desperate for bag or case that will fit it. I cannot leave the telescope set up so it has to be put away each time and good cases/storage bags will make the world of difference to taking the telescope to darker skies and keeping it safe at home. Do any of you own this telescope (and mount)? Have you found a good case that you can recommend? Please let me know!
  12. Anyone pulled the trigger and bought one of the new finder scopes,, deffo like the look of it,, finder scope ,,lol,, more like a nice video astronomy scope..
  13. Hi again after thinking about getting the 130p dob I think I’ve change my mind and have decided to go for the bigger 200p as I’ve realised it’s not that bad to carry after looking at some videos. As I mentioned before I don’t really have a good telescope at the moment and have never seen Galaxies or Nebulae properly before. These are my main interests and objects I’ll be observing the most ( and maybe star clusters) . I was wondering if the 200p is good for this type of thing? I live in a south facing garden ( if that matters) and relatively low light pollution.I’ve also seen filters which you can buy to get the best view out of them but not really sure how they work. Or would I be better off getting a refractor? Thanks for the help.
  14. Hello again, ive done some thinking and I’ve decided that I want to save some funds for getting a good set up for AP as this is what I really want to do. My budget will probably be £1000-£1200 saving £50 or so every month towards the kit. ( better to do that then blow all your money and be bank rupt for the rest of the year ) Even if it takes a year or longer I know it’s going to be worth it in the long run. Anyway, I have been doing some reading on here and using Every Photon Counts ( need to re read it as I still dont understand it properly) people are saying that the HEQ5 is the bare minimum for AP. I’ve seen this on FLO https://www.firstlightoptics.com/pro-series/skywatcher-evostar-80ed-pro-heq5-pro.html which looks like a good set up or is there anything different you would recommend? I still have to get a camera which I’m most likely going to get first so this isn’t included in the budget. My primary targets is DSOs ( obviously ) I was thinking of getting the 130pds on that mount but I would like to hear you suggestions on maybe getting a different Mount or scope. I’m thinking of maybe going second hand if possible. Thanks fo the help Olly.
  15. Hello again, after settling on a dobsonian I think I’ve decided not to get one, and I have come across the Skywatcher Startravel 120. This looks like a good telescope especially for wide FOV,and seems like a good grab n go scope too. However I have a few questions that I would like to ask and no better place then to ask them here 1. People have said that there is noticeable CA when using these types of scopes. How much of a problem is this? and are there any filters that are available that can reduce the CA if I find it a problem? 2. The last question I have for this scope is on FLO they are doing a deal with the 120 on a AZ3 mount.One of the reviews (well the only review ) said that they had found it wobbly on the AZ3 Mount and decided to get an AZ4. Is this necessary or is it capable with the AZ3 Mount if it’s only for visual. here is the link to FLO for the set up I’m looking at https://www.firstlightoptics.com/startravel/skywatcher-startravel-120-az3.html Would also like your feedback on the scope too if possible Thanks in advance
  16. Hello again, After a lot of you gave me some good suggestions for what my first scope should be someone had suggested the Skywatcher a heritage 130p. I just wanted to know if anyone has had this scope and would to share your opinion/experience with it. I was looking something portable and under £200 and this seems to fit. But when scopes are usually this cheap sometimes they don’t perform that well. Also I wanted to ask is having a open tube a problem for dew etc. Many Thanks, Ps (here is the original post if you have anymore suggestions) someone had mentioned
  17. Hi everyone , Have just joined the forum as i am looking to buy my first scope ( well second ). About two years ago i got a National Geographic 76/350 compact scope as a gift. After using it alot i've decided to upgrade as i would like to see more. im still relatively a beginner knowing my way round the sky have bought a few books so hopefully that will help Turn Left At Orion being one. As you can tell by the title i'm looking for something for £200 or less. I'm not looking to do photography with it, i just would like something better than the scope i have at the moment. Easy to use and to set up would be a plus as well. I don't need anything extremely portable but i do have to use stairs so that might be something to think about. Looking forward to reading your suggestions.
  18. Hello, ive still haven’t made a decision on what telescope to buy yet ( been very hard to decide what to get ) My Max budget is £400 if I know it’s worth the price.I’m looking for something that’s relatively simple and easy to set up. I was thinking about the 200p but I think that maybe a bit awkward for me and was looking to do some sketching so a goto Mount or something similar would help. I’ve found this scope https://www.firstlightoptics.com/az-goto/skywatcher-startravel-102-synscan-az-goto.html I was wondering if anyone has used this scope or knows more information about it than I do. Was wondering how “portable” it is and what the weight is for it. I’m looking to look at most things through the telescope but not setting my expectations too high. My skies are quite good 4/3 bortle scale. And will be storing it in a garage also will be stairs so need something easy for me to carry. And I’ll be going to a field opposite my house for better viewing. Sorry for keep asking what scope to get as you can see I’m not very good at sticking to a scope . Cheers Olly
  19. (Sorry for double posting hopefully one of the mods can delete my original post) Hello all, hope you’ve all had a good week, been a few clear skies this week . In the next couple of months I’m going to be purchasing the 200p Dobsonian. And doing some research people seem to struggle carrying the ota because of how awkward it is.I was wondering if anyone has successfully put handles on it to make it easier to carry or other solutions I have found this on eBay https://www.ebay.co.uk/itm/Awning-Pole-Storage-Bag-Deluxe-Hardwearing-Holdall-/142422407055?_trksid=p2385738.m4383.l4275.c10 not sure if it’s the right dimensions I’ve also seen people suggest heavy duty trolleys. But I have to use stairs to get to the garden so that’s kind of out the question ( and might need to make a 2 minute walk to a field). Any help would be appreciated and also if possible to post me some images of what you’ve done. I don’t really want to drill in the ota to make holes for a handle.
  20. Hello again, After many hours of researching and asking on forums I’ve decided not to go down the imaging road as I’ve come to realise it’s way out of my budget. Now after realising this I’ve narrowed down to three telescopes that I’m considering on getting purely for visual use.. Skywatcher 150p 150pl or the dobsonian 200p. What is the difference between the 150p and the pl? I’m after something that can let me see enough detail on planets that I’ll enjoy and also allows me to get views of deep sky objects. I have been talking to Martin from FLO as well and still can’t decide. I’m hoping you can help me make my decision. I’d also like to know how comefortable these three are as I’ll be most likely doing long sessions for sketching. My budget is £400 max. Thanks for for the help (again).
  21. I've been getting started with an EQ3-2 GOTO / Skymax 127 combo, and had a couple of queries / concerns about the mount; advice would be greatly appreciated. With the clutch released, rotating on the RA axis the mount meets resistance when the counterweight bar approaches horizontal. It's enough that sometimes the motor drive can get stuck; there's no clicking from gears skipping, but movement stops. If I undo the RA setting circle screw the resistance is gone so I thought that was my error as the manual says to unscrew when locating, but as tracking is on the RA axis and the screw would normally be tightened at that point, is this an issue with the mount? I'm not expecting to use the circle so I can leave the screw loose and it seems that it'll be fine, but I'm wondering what the issue is. I've looked at badger's teardown, but I really don't want to take it apart yet as it's new and there isn't much backlash and no slop (if I understand the term correctly). I'm also wondering whether the DEC circle is set incorrectly at the factory and needs adjusting, or is this a misunderstanding on my part. After polar aligning, I assumed that having the arrow on the side of the mount head point to 90 on the DEC circle would have the telescope pointing correctly home positioned, however with a 1 star alignment my home position was clearly incorrect, and after doing a 3 star alignment (and getting good tracking after that) and returning home the DEC circle was around 78. Using a spirit level on the head, if the edge of the mount head that's parallel to the scope mounting plate when it's tightened and horizontal , the DEC circle is around 12 (or 78 if vertical), however if the edge of the head that has the two screws that secure the plate is horizontal, the DEC circle is 0. So it seems as if the DEC circle was set based on the orientation of the side of the head that has the screws, which doesn't lie parallel to the scope mounting plate, rather than the edge that lies snug against the mounting plate. Does that sound plausible or should the DEC circle be at 12/78 when the scope is horizontal or vertical?

Edit: 24 Jan 2018 - stars a little brighter and tighter with no change to the rest of the image ( NGC 2359 - Thor’s Helmet ) ( please click / tap on image to see larger and without compression artefacts ( and double click on that image if you what to see it as I posted it ! ) ) ................. original: Thor's Helmet ( NGC 2359 ) in the constellation Canis Major Thor’s Helmet ( Duck Nebula, NGC 2359 ) ( please click / tap on image to see larger ) This HDR image shows the bright nebula Thor’s Helmet in a sea of colourful stars against a background of red from dust and HA emissions. The stars in this image range from the brightest ( bottom right, HD 56501 ) at magnitude +7.7 to around +20 or more. HDR capture and processing allows all of the stars to be portrayed in colour without any burnt-out highlights. The colours of the stars and nebula are as close as I can get them to their "true colours" by using a "daylight colour balance" and allowing for the extinction of blue-green due to atmospheric absorption/scattering ( mean altitude during capture ~ 60deg ). The blue star in the centre of the bubble of expanding stellar material is HD 56925 ( WR7 ) - a massive, unstable and short-lived Wolf-Rayet star that one day will detonate in a supernova.

  23. Hi all, Thought I'd share the clip I designed to fit a Right Angle Finder to the polar scope on my Star Adventurer mount. I designed it to work on my Neewer RA Finder but it could possibly work with similar ones (that have the removable adaptor plates for various camera types). My finder came with a few different adaptor plates and I chose the metal screw-together type which was labeled for use with the older Nikon F series cameras. As you can see from the photos, this just screws into the printed clip allowing you to leave it in place on the Polar Scope but remove the RA Finder easily. It is best oriented with the clips at the top and bottom (rather than on the side). I've made it available for download from Thingiverse, there's a printable version of the adaptor plate on there too (along with instructions and pics) should you need it. https://www.thingiverse.com/thing:2762334
  24. Sincere apologies if this has been covered previously in the numerous newbie SA questions. I had a search here and on Google using many different ways of asking but can't quite find the answer. I've just received the SA astro imaging bundle and have been familiarising myself with it before the skies clear. Am I right in assuming that by setting the date/time to October 31st at 00:00 is just to align the polar scope reticule squarely? As I understand it, once polar alignment is completed, it will rotate as the L bracket and camera are positioned. I have the PS Align app on my phone and the reticule set in that matches what I can see through the polar scope (clockwise 0, 3, 6, 9) so I think I'm on the right track and know what I'll need to do there. However, the month markings on my SA have a wider division at the end on the October range, as do all the months with 31 days. You can see them in the attached pic. The only images I've been able to find on-line (and the diagrams in the manual) show equal divisions throughout. So, I guess what I'm really asking is, do I align as per the attached photo with the 0 on the last division mark in October? The reticule looks pretty level to me but I didn't know quite how crucial it was. (I'll try not to have such a rambling question next time.) Simon.
  25. Hi Folks, I have been happily using my new skywatcher skymax 127 on a synscan az goto mount and a question occured to me when going through the alignment procedure. Does the time between centering the first star in the eyepiece and aligning the second star matter. The reason that I ask is that sometimes the accuracy of the goto differs slightly and I am wondering could it be due to me being too slow to find the next star. I am good with constellation identifying but the star names I only know a few of the major ones such as vega, betelgeuse etc., so I have to rely on a star chart to pick a suitable star which takes maybe about an extra minute. I am wondering if the mount does not keep the 1st star centred due to setup not being fully complete at this point and obviously the earth is still rotating so the star will drift and then the reference point of this star is now not centered when aligning to the 2nd star. Everything else is always the same as I have already marked the ground where I put the tripod so it goes in the same place every time and levelled it with a spirit level. The power is supplied with a skywatcher powertank so I know its not a battery power problem and all the information is correct such as time/date, elevation, lat/long etc. It isnt massively out, so far everything I have requested has been in the FOV of my 25mm eyepiece but its just something that I wondered and also whether I could improve things. cheers
