  1. Hi all seeing was not not great but needed my moon fix,x2 barlow dmk21 mono average 1000 frames at 30fps average 400 stacked .forgot to name some craters because i forgot there names seeing rubbish but another not bad night pat
  2. Hi. i haven just purchased my first telescope (Celestron Nexstar 8SE) and I'm trying to source the correct AC adapter for use in the UK. Does any know which is the correct one - 3 pin version and where I can get one. Many thanks nick
  3. Hi Folks My 6 month old (used 4 times) Celestron Nexstar SLT 127 Matsukov Cassegrain has always given alignment problems. It is difficult to align and once aligned, quickly goes out of alignment. Just this evening after using the Solar system align using Venus, I selected Mars (which is very close to Venus these days). The scope went about 5 degrees south of Mars. When I sent it back to Venus, it didn't go there either. I have had problems with the two star align as well. Once aligned, it held Saturn for about 15 minutes before going out of the field of view, but when asked to go to a different star, it gets quite lost. Sometimes it goes below the horizon looking for things ! I don't know what to do. Returning is not easy given that I am not in US regards Rajeev Kingston Jamaica
  4. I recently got a Celestron Astromaster 130EQ Telescope for my birthday and have been having loads of fun looking at and taking photos of the Moon over the last few days. One issue I had with the scope was that I couldn't angle the Red Dot Finder down enough to align it with the object I could see in the Telescope. I have been using it by taking note of the distance the red dot was out and trying to direct the telescope taking this difference into account. It occurred to me (before I looked at this forum) that if I could only raise the tail of the red dot finder higher (I could see that to bring the dot down the LED at the back was raised), I could get the alignment accurate. I took the mounting bracket apart and looked at the design of the plates. I then designed some new ones in Sketchup widened the back dimension and, as I have a 3D printer, printed the new ones out. The new bracket plates are 2mm wider at the back hence raising the back of the finder higher by 2mm, which in turn lowers the red dot down to it's correct alignment point. I thought I'd post on here to say how I resolved this issue as I notice that others had also suffered from this problem. I have posted the STL (design) files for the 3D parts up onto Thingiverse should anyone want to download and print some for themselves, I will also put out an offer to print some for others should they not have access to a 3D printer (just PM me). Here is a picture of the new mount plates in place. Terry.
  5. Hail esteemed astropeeps I set up the Celestron wifi module on my Nexstar 6SE (good wifi signal, no problems connecting), opened Skysafari 4 onth' IPad, but all I got after I had been into skysafari settings and put in the IP address was connection failed. I have the settings on direct input (it is like that on the actual wifi module too) alt-az go to, selected my telescope, but always connection failed. Tried it on sky portal on IPhone 6, and whilst it did connect and slew the telescope, the alignment procedure failed every time. Does anyone one have any advice, please? Why won't Skysafari 4 connect (actually 4.5.3) and why won't sky portal align? I've checked other forums and other posts and all the settings seem to be correct. What button have I failed to check? If you have screen shots of any settings, that would be helpful.
  6. Hi there. I finally decided to replace my old Orion Starshoot with a nice new Neximage 5, and at the same time got a laptop sporting Windows 10. The camera came with iCap software, version 2.2, and installation proceeded without incident. I got to the point where iCap was recognising the camera, but when I clicked on 'OK' iCap stopped almost immediately, at which point an error message came up announcing that iCap had closed and Windows was (allegedly) looking for a solution. I repeated the 'launch' exercise several times, always with the same result. It's really frustrating, as I just can't get on with imaging at all. Does anyone have an idea what I could try to get my Neximage up & running properly? Thanks Alan Stewart
  7. Hello, Does anyone have any experience or knowledge about whether it's possible to mount alternative OTAs with a dovetail or rings to the mount that comes with a Celestron Nexstar 80GT? In particular I am wondering about attaching a SW Heritage 130P? I know that Celestron did a 130mm reflecting 'scope on his mount, but it looks to also have that plastic tube clamp, seen on the 80mm image below. Thanks, Gavin
  8. Hello , I am physics student in Turkey . I have used telescopes but they were manual mount because of that I do not have any experiences with GO TO mounts . I upload photos and I pressed alignment button before finding 3 or 2 stars . Still ı did not find any stars from catalog . I really watched many videos but I did not do it well my process still not continue . 12 photos I upload , first photo teleskop , last photo is the my last step , which button should I have press?
  9. Hi! I am very new to SGL (just signed up a couple of mins earlier) and to astronomy as well, though I have been facinated with celestial bodies since I can remember. I recently purchased a Celestron Powerseeker 127EQ but now I’m having troubles using it and I can’t seem to see anything through it. I also have a Celestron collimating eyepiece but I still can’t seem to make it work. Anyone here who has experience with the same scope? Would appreciate if we could chat a bit as I would be really interested in your experience and how you ultimately made it work!
  10. Unexpectedly i ran into a guy selling a Neximage 5 imager for just $70 canadian so i figured it would be a decent beginners camera and since i'm an imaging noobie i just grabbed it. I am aware it will not be for solar but i figured why not start with small steps in imaging before i buy my good camera, $70 is not a pile to waste should i only use it on limited objects then never touch it again lol. Does anyone out there have any tips and tricks that would be useful in my attempts for first time imaging??.
  11. Hi gang, I have a small issue with my CPC & need some information from other CPC owners. Basically I was having a look at the Fastar connection for Hyperstar but noticed that the whole Secondary assembly was a little loose & could be rotated on its own leaving the corrector plate securely fixed. Here’s where I made my first mistake, I lost track of the original starting position of the assembly but it didn’t end there. The only way to tighten the assembly & stop it rotating freely the corrector plate needs to be removed as the Secondary unit is tightened on the underside of the corrector. Next mistake, I forgot to mark the corrector position to aid refitting, not considering the fact that it’s position would be important on reassembly. Turns out that my corrector has no significant markings on it except in 2 places on the edge, about 45° apart are an arrow pointing to the outer face & the number 4. Through much head scratching & the use of digital calipers I think I have found the correct orientation of the corrector plate in order to reassemble but I am still stuck with not knowing the correct position of the Secondary assembly. I have read various articles that contradict each other stating that one of the 3 collimating screws should be at 12o’clock or 6o’clock. What I have noticed though is that when the outer retaining ring is unscrewed from the Secondary assembly, there is a small locating grub screw that sits within a slot on the assembly housing, see pic: a big ask I know but is it possible for other CPC owners, mine being a 9.25” if it matters, to unscrew the Secondary retaining ring & note the position, on a clock face (top of OTA as 12), of this locating slot. It would be much appreciated. Thanks I know there’s plenty of discussion pertaining to Primary & Correctors as marching sets, although from what I gather this was for earlier SCT models, plus 365 Astronomy lists the corrector as a replacement part: https://www.365astronomy.com/Celestron-C9.25-Replacement-Corrector-Plate-50984-1S.html so I’m hopeful that nowadays the matched pair issue is not relevant & ive got away with my stupid mistake. Regards.., Kirk
  12. Newb here. I have settled on my first telescope being the 4SE or 6SE and I have a Sony Alpha 300 DSLR I would like to be able to connect to play around with AP. I am barely starting to grasp the terminology involved with telescopes in general but it seems connecting a camera to a telescope is a whole different ball game. It seems as though the 4SE has a separate eyepiece and camera attachment? Looks like you can just flip a knob to swap between the viewer and camera? Whereas the 6SE it appears that you have to remove the whole eyepiece to connect the camera. After reading some reviews everyone says they immediately wanted a more powerful telescope so I am thinking the 6SE may be the way to go but I really don't like the idea of having to swap back and forth by removing the eyepiece, is there an after-market accessory that would allow it to work more like the 4SE (flip a switch from viewer to camera and back)? And I guess my other question is are the optics really that much better on the 6SE that it would be worth the hassle when connecting the camera? I see that the light gathering capability and magnification are better but how perceivable is that difference? My goal is to do some moon viewing but it would be great to see some cool deep space objects too. + One final thought, how much does the auto star tracking feature help or hurt the image quality? I mean on a 20 second+ exposure the object is going to move some amount, is the Nexstar tracking system really able to keep the object that precisely still in the optics? Or should I just expect to get blurry spots of light when photographing deep space objects? Thanks
  13. Hey guys this is my first time on this website. I bought a Celestron 50az and I am able to observe the moon very clearly, but I'm having problems observing planets can someone explain to me step by step how to observe planets with this telescope. Also can I view nebulas, galxy, clusters with this? ( I think not, right?) Thanks!!!
  14. Greetings! I've had my telescope for a couple of months now and I still didn't get the chance to try the sky align option, I watched some video and tried aligning my scope many times but it never seemed to work. I only use it to watch the moon and I have to manually move it every minute or so because it keeps getting out of frame, how can I set it to track the moon on its own? I wanted to see Saturn a month or two back but I couldn't do it, I'm planning on trying again tomorrow as I'll know where it'll be in relation to the moon and mercury. Any tips you can give me? I really want to see Saturn. (Also, will my 25mm eye piece that came with the telescope work to see Saturn?) Thank you
  15. Hi all, I have celestron astromaster 130eq scope ..it is very difficult to view through 20mm eyepiece..is there any other for broader view for both terestrial and astronomical viewing?with good eyerelief as I wear glasses..32mm is good ..please reply
  16. I am a newbie and want to know how to view Jupiter. When I do this myself, when I start focusing it becomes smaller and brighter and I am not able to observe the bands. PowerSeekerAZ.pdf
  17. What should I buy for a Canon 40D (Astrophotography): a Celestron EdgeHD 8" AVX or a Celestron AVX SCT 9.25" since the price differs only for 100EUR? I want to have nice DSO pictures but be able to see planets as well. Been using a 114mm reflector for 6 years. Thanks in advance

  19. Currently I have 25x70 SkyMaster bins but I think they are too high magnification to be gliding the night sky with (I got them for £35 so I didn't mind much). So I'm on the lookout for a set of Skymaster 15x70 or 12x60 bins Thanks, Tom
  20. I tried to use the GoTo function on the Nexstar SLT 130 for the first time last night. I got through all the steps to set in date, time, place etc. But When I have to find 3 objects in the night sky, I have to use the direction buttons on the handset, whenever I press one of those 4 buttons, the handset just dies out. The screen becomes green, it says nothing on it, until 1-2 minutes later, it says something about error 16 or 17. Keep in mind that the whole handset works up until the point I have to use it to align. What this means is that my scope does not move up or down, nor right or left, since it just shuts down. What I've tried: - Change batteries (AA's) - Try to use a power supply - Updated the firmware in the handset to the latest version What could be the problem? - Mehtevas

  22. Hey SGL, So i have purchased a set of Celestron EP's with some filters and upon inspection some of the filters seem to not look overly "clean"? Several of them have what could be best described as water marks whilst another has a piece of something on the filter... Am i able to clean these at all or would it damage them? I haven't got round to checking the EP's but i would hope they are all okay! Celestron Eyepiece and Filter Kit 1.25in (Purchased from here too) If anyone has any advice on cleaning them (if possible without damaging them) or what to do that would be great I am not sure what is considered reasonable and what isn't when it comes to this sort of stuff!
  23. I am selling my Celestron EDGE HD 8 inches, a change of direction has made me realise that I prefer wider field of views than the Celestron currently provides. I purchased this second hand last year and have never looked through it and literally unpacked it to take some pictures today! For sale: Celestron EDGE HD8 (faststar compatible) Double CGE dovetail bars (1 top and bottom) Celestron T adaptor part number 93644 Celestron 9X50 finder part number 51611 Celestron Dovetail for the finder Celestron 0.7 focal reducer specifically for the EDGE HD8 Also comes with Baader 2inch visual back, quick lock - these are fantastic and so easy to use, one of the best upgrades for any scope. I also have the original paperwork, manual and the original packaging. RRP for everything listed is a smidgen under £1500, I'm asking £899! I am willing to haggle but please no silly offers, I would prefer collection or could meet half way depending on location. I don't really want to trust couriers with any optical equipment. Really a great scope, but not using it so please someone buy it and use it for it was designed for! Thanks for reading, and please contact me for any additional information. Neil.
  24. The inability to achieve reliable precise focus when doing AP, whether it be deep sky or planetary has finally taken its toll on my last nerve. 80% of my scope time is spent imaging with a Celestron 8" Edge HD (with .7 reducer for deep sky) attached to a Losmandy G11 mounted to a permanent pier in a roll off roof observatory. So I have come to the decision that its overdue for an autofocuser, preferably one that I can also control from my PC. I have read posts from users of Edge HD systems experiencing problems with backfocus in the image train when using crayford type systems like Moonlite etc. So I have primarily been looking at primary autofocusers like the ones from Rigel systems, (unb stepper) Robofocus and JMI. Frankly there is so much info on the JMI page that it is difficult to see what is needed there, let alone calculate a cost. Plus the Rigel system and Robofocus do seem to fall more into my price range for a remote access system (inside my home). So I am looking for advice, recommendations, warnings etc on either of the systems I have mentioned, plus if you know of another that works with this scope, I would love to hear that to. There is the possibility that I may upgrade the 8 edge to an 11 edge sometime in the future, so a system with a conversion kit would be a great bonus. But for now I just want a reliable precise way to autofocus via hc & pc. Thanks for any advice you can give, Randy
  25. I know it's not an ideal scope for astrophotography and I'm not expecting anything special since I know about EQ mounts etc. If it could get up to 30 second exposures I'd be happy.
