  1. I have recently bought an iOptron GEM45 (from FLO) and I am a bit mystified by the Zero Position. The hand control gives you the options of "Goto Zero Position" and also "Search Zero Position", but they appear to do the same thing! Does the mount have sensors like the Home position of a Paramount, which sets the axes to an exact hardware position, or is it something else? I guess this is the same for other iOptron EQ mounts so maybe a skilled user can enligten me. Many thanks Chris
  2. I have decided to sell my Cem-120 mount as i got a second hand AP 1100 GTO from my friend who got a new AP 1600 with encoders its just under a year old bought from Altair Astro so still under two year warranty is in mint cont i couldn't miss the opportunity to get AP 1100 GTO and let it go still waiting for pier plate for mount. So theirs no point in keeping two large mounts after i got my dream final mount buyer will pay shipping price is 2150 pounds. Altair Astro price without Ipolar Camera is 3250 pounds without Ipolar Camera which is 200 pounds total 3450 pounds
  3. Hi everyone, I decided to sell my iOptron iPolar, that is currently mounted on my SkyGuider Pro. I only used it a couple times so it's like new. Since I'm now using another mount, and will probably sell my SkyGuider eventually, I no longer need the iPolar. Please note that it isn't compatible with other mounts, mainly because the USB slot is on the back of the camera, not on its side. Price is £150, including shipping from Munich, Germany. Payment via Paypal or bank transfer. Please let me know if you have any question or if you need pictures! Thanks!
  4. Hey all, I'm considering and tempted by an iOptron CEM25P. Just wondering if there's any owners (current or former - for any reason) who can share their experiences with this? I intend on buying it new, so a substantial wedge to drop. Many thanks
  5. The postman was kind to me today and dropped off a William Optics Zenithstar 61 and Flat61A flattener and the gods smiled on me with clear skies for 30 minutes. It would be a shame not to christen the new toys I only managed 10 lights so I didn't even consider darks or flats. The 10 lights from the Canon 5D MkIV, shot at iso 1600 x 60 seconds, were stacked and aligned in PS, median filtered for some noise reduction and then a few layer/curves tweaks to pull out some basic detail so I could look at the star profiles and and any vignetting. Overall impression is extremely good build quality and the focusing through the mask is ok on very bright stars but quite a challenge on lesser star magnitudes. Very little vignetting through the imaging train so the image circle cover the full frame sensor and it will be simple to either remove the gradients in PS or use flats and sharp stars corner to corner with no obvious colour aberrations. I do need to check where the weird smudges are in the imaging train because they weren't on the camera sensor yesterday, hopefully I'll find them pretty quickly because they are nasty! Screenshots are also included of APT focusing, Stellarium for the imaging area after plate solving in APT and then PHD2 for the guiding with the ZWO ASI120mm-mini camera on a ZWO 30mm f/4 scope (I've no idea if the guiding is good or bad but the polar alignment was achieved with the iPolar camera in the SkyGuider Pro mount I think at some point I'll add an 2" IDAS D2 filter into the imaging train and see if I can counter some local light pollution we have around here.
  6. I had bought this in the hope that i will do astro trips more often. Hasn't happened and i use my avx at home. So this is not finding much use. An extremely portable setup, the mount with weight and tripod leg spreader fits in a shoe box. The stock nuts have been replaced by winged nuts for easy grip in the dark. One of the tripod's legs suffered a slight damage, but I've taped it well and does not affect its performance. I will include the computer connecting cable as well as polemaster adapter. You can read its review here: http://www.altairastro.com/public/ioptron/Skyatnight_95_april2013_ioptron_smartEQPRO-review.pdf Will prefer pickup from London as the postage may be tricky due to the tripod £250.00
  7. Hi. Has anyone used this mount. Sky at night magazine gave it very good review, but elsewhere I read stories of tracking issues. How would you rate it compared to an heq5? If have an 80 mm Ed scope most likely to be used for AP, but I would like option to observe visually with an 8" newt. I Suspect the latter would overload it? Thanks Mark
  8. I’ve been having issues with platesolving using Platesolve2 and my Ioptron IEQ30PRO Mount, I’m connecting using the Ioptron Commander Ascom driver. I’m using Maxim DL5 to locate and image via the Planetarium section. When the Maxim platesolving fails, especially when I’ve just started in a new location, I need to use Platesolve2, which is installed as an add on. Unfortunately I can never sync once it’s finished platesolving as the telescope disconnects at some point in the process. I only use the above setup at Star parties. At home I have an observatory with Eqmod running an eq6. I don’t have any problem using Platesolve2 in a Maxim. I was wondering if I should be connecting using POTH in between Maxim and the telescope driver. I don’t generally connect a planetarium programme now I use platesolving but I want to use The Sky6 to help with camera orientation in the future. As I understand it Eqmod will act as a hub allowing this but Ioptron Commander won’t. This may be why I have issues when using my Ioptron Mount. Can someone confirm that I’ve understood the process correctly, please? Anne
  9. Hello to all, I have got a chance of going for a IOptron CEM25P that I want to use in my back garden. I also would like to take it on my travels around the UK and possibly abroad. I have organised a deal for this mount together with an 80 mm triplet refractor and guide scope. I can order the mount with 1.5” or 2” legs; weight difference is about 3kg for the heavier version, extra cost about £100. I just wondered if anyone could advise if the 1.5” legs would be good enough and stay stable in the wind? Does anyone own this mount and have either of the two sizes of legs? I would love to hear your experiences before I finally put in the order. May I thank you in advance if you can offer any help. Cheers!
  10. I bought a new CEM25P and just spend two nights trying to get it to track. I've had many GEM mounts over the last 30 years, so I thought this would easy. But it seems that either I have a problem with the mount, or I am getting old. I leveled, balanced, and polar aligned the mount well. Then I attached a guide scope. I did NOT attach the cable from the guidescope to mount. I also did not attach the mount to my computer. This way I could watch stars drift and get an idea of was going on with just the mount. I checked the CEM25's tracking rate, and it is set to sidereal. LAT/LONG and perfect. Time accurate. Next, I watched stars drift on my laptop using PHD. When the mount is turned on, and tracking turned ON - the stars move somewhat quickly in RA. Like they are slewing slowly. When I turn OFF the tracking (zero key) they still drift, but a little slower. When I turn off the power to the mount, of course the stars drift, but at slower rate still - normal sidereal rate. When I turn the power back on the stars drift a little faster. Turn the tracking back on, and they drift faster still. But when I set the slew speed to 2x, and press and hold down the left arrow key, and the stars STOP drifting. Perfect tracking. Thanks for any advice! CF
  11. This is the original iOptron Sky Tracker. Comes with the polarscope, case and manual. In excellent condition. Please note this is NOT the v2 version which has the azimuth adjustment - I used a panoramic head to adjust the azimuth. Although this model has been superseded by the v2 and now the pro versions it still tracks extremely well provided you get it polar aligned (just the same can be said for the newer models). However as this is the older model I'm selling it at for just £95 including postage within the UK Payment via paypal (sorry, you pay the fee or send as gift) or bank transfer.
  12. iOptron has improved what was already my favorite portable AP mount. The CEM25P now actually guarantees a periodic error of less than +/- 10 arc sec, which guarantee, as far as I know, is unprecedented for this category/price (£799 currently at Altair Astro). You can read my full review here, although with the winter weather I have only managed a couple of decent sessions. Overall, it includes some improvements over its predecessors ZEQ25 and CEM25, while retaining the amazing lift/weight ratio it is known for and my unit does actually show a PE that is well bellow the specified +/- 10" (less than 2 cycles were recorded, so if I record more to remove non-PE noise it might be even less):
  13. This very useful upgrade kit will give you full Goto when added to an EQ5 or Vixen GP type mount. This is an extract from the instructions: The GoToNova® dual axis GOTO upgrading kit is available for the EQ5-like mounts (144 teeth). The kit is compatible with the following mounts: EQ5, Vixen Great Polaris (GP), Orion SkyView Pro, Celestron CG-5, Meade LDX55/LDX75 and Astro-5. The kit may also be used on the older Vixen Super Polaris (SP) with some more modification to the housing. I am selling it because I now have an AZEQ5 so do not need it any more. It is in good condition, fully functional and works very well. It is easy to fit to a Vixen GP mount (I have done this), and should be similar on an EQ5. The others I have no experience of. The hand controller has a nice clear display showing good detail of what is going on and making it easy to use. It will connect to SkyFi type systems to allow control from a smartphone/iPad via SkySafari for instance. Full instructions here: https://www.altairastro.com/public/ioptron/GoToNovaKitV20.pdf Looking for £200 Plus postage via PayPal fees paid or bank transfer. Photos at the weekend! Cheers, Stu NB Now also on ABS. Will resort to eBay at some point too!
  14. Hiya, I recently treated myself to the iOptron SkyTracker and tried it out for the first the the other night. I kept getting star trails (which I later realised may have been due to the fact that I had it set to half speed! Silly me!) But I also had a lot of trouble with the polar alignment and I feel that, even if I had had it set to the correct speed, I still would have been getting star trails... These are the steps I went through, can anyone tell me if I am doing something wrong? I levelled my tripod and faced the tracker towards North I set my latitude to around 56 for the UK (Perth)... am I right in thinking that Polaris should then be within the field of view if I just pan my tripod around? This is where I think I messed up, as I couldn't find Polaris anywhere and had to significantly increase the latitude to find (what I thought) was Polaris. Did I maybe not level my tripod properly at the beginning? I was in such a rush to start imaging, that I probably didn't pay enough attention when I was setting it up! I used a polar alignment app and placed 'Polaris' (in hindsight I think it might have just been a random star that I thought looked decent enough ) where it was meant to be... but I just got rubbish pictures... So if anyone has any advice, I'd be very grateful!! Also, if anyone has any images taken with the iOptron SkyTracker and wouldn't mind sharing them, I'd love to have a look! I live in a fairly light polluted area and my first target was Andromeda... not the best combination, but is it still possible to get a semi-decent picture? Thanks!
  15. Hi, having recently upgraded to a telescope I no longer require my iOptron SkyTracker 3302W. I purchased it from WEX Photographic & to be honest, I have only used it in anger 3 or 4 times because of time constraints. It is in perfect working order in original packaging & box as seen in the pic below. A word of warning that I found out through trial and error is that unless you use exceptional quality batteries, tracking time & accuracy will be compromised. The unit does however have a 12v input & I used a Celestron Car Battery Adapter cable to power the Tracker but any 12v supply that ends with a male 2.1mm center positive cable will do. Full specs are available here: http://www.ioptron.com/product-p/3302w.htm Due to the weight 1.7kg I would have to post the item via Royal Mail Special Delivery - Guaranteed by 1pm next day, this is reflected in the post price. So, price: £190.00 collected £200.00 posted (UK only: UK services cover the Highlands and Islands, Scilly Isles and the Isle of Man but not the Channel Islands) Sensible offers may be considered. Payment via Bank Transfer prior to posting or cash if collecting in person , (finer details to be discussed via PM after sale agreed, as per forum rules). LISTED FOR SALE ELSEWHERE Any questions I'll try to answer as quickly as possible. Thanks
  16. Due to to a combination of a change of shift pattern at work&a shoulder opI had last year Im reluctantly putting up my imaging setup for sale.It comprises of the following: 1. Ioptron ZEQ25GT with custom made CWs and extendable shaft,custom made pier head adapter with materials to make a DIY pier 2. SW 200PDS with rotating ring and secondary dew heater 3. Optistar AR80S Dual Speed 4. Modified Canon 350D with charger and battery 5. Astronomic CLS CCD 2" filter 6. SW Coma Corrector 7. Astronomiser 10m cable(for camera control) 8. QHY 5-II camera with guide scope adapter 9. Hotech Laser Collimator 10. Phillips SPC900(not in original casing) 11.DIY dew heaters and control unit 12.Bahtinov masks for both scopes Comes in a flight case and a few other bits and pieces that you see in the photos.I've attached a photo of The Witches Broom which i took with this setup,photoshop not being of of my best skills £1300 ovno
  17. Finally received my QHY5l-II from Astronomia so had a go at setting up PHD2 last night/this morning.Finding stars with this camera was easy compare to the SPC900! Equipment used: iOptron ZEQ25GT,SW 200PDS with an Optistar AR80/QHY5l-II piggy backed,default settings in PHD2.Once locked onto a star it all then went pete tongue,the graph below tells the story of my 1st attempt,the RA just dropped off the scale! So after this I altered the counter weight on the mount which gave me this graph,maybe get the balance better on the mount? Then the dec went 'off course' for some reason? Managed a 5 minute sub with this but compared to some graphs I've seen this isn't right! Any tips etc much appreciated!
  18. I have been loving my Celestron Nexstar 8SE scope for viewing the night sky and am starting to think about getting my next scope to use for imaging. I bought a copy of 'Making Every Photon Count' a week or two back and have just finished reading it (very well written book ) and I am now thinking about what my options are. I have already ordered an INOVA PLB-MX Mono planetary camera to have a play with on my Nexstar to see how things go with imaging the Moon / Jupiter / Saturn & Mars. This camera should arrive tomorrow. I have also ordered and received a set of LRGBC Baader filters and filter wheel. I am hoping that these items will give me a good indication to if I am going to enjoy doing this sort of thing, or if it just going to irritate me that I can't get the computer software to work . I spent over the odds on this camera as if I do enjoy doing this sort of imaging, this camera should be a reasonable starting point for some DSO with my new scope (see later), and if I get really serious about things, it should hopefully proved to be a good investment as a auto-guiding camera. So, on to what I need to get; the mount and scope. First thing is I want some thing which is portable and pretty quick and easy to set-up. As I have already got a filter wheel and a decent set of LRGBC Baader filters, the scope must accept a 1.25" adaptor, as I do not want to re-buy this sort of thing in 2". My idea of a good night would be to spend 30 minutes setting up the imaging scope / camera / laptop and leave it taking some photos while I set up the 8SE next to it and spend 2 - 3 hours viewing the night sky. I then pack up the lot and spend the next five cloudy / wet nights processing the images I have taken. With all this in mind, this is what I have though of as being a good option which should (hopefully) keep me going for a fair while:- Mount - iOptron ZEQ25GT. This seems to have got some good reviews, fits the portable bracket and is not too expensive (in the grand scheme of things). The one thing which concerns me is not all that many people seem to have one, which could be because it is fairly new and not all that well known, or it could be because it is not that good? What do people think of this mount, and what else should I be considering? Scope - 80mm F6 Super ED Triplet Apo 80/480 Altair Wave Series 2014. I have seen some nice images taken with this scope, and logic would say that it was a good match for the iOptron mount. Again, it fits the portable criteria, but I am sure that there are lots of other scopes which also do this. Does this seem like a reasonable choice and what else should I be considering. So, these are my thoughts. I am in no real rush as as I have said, I want to see how I get on with some planetary / luna imaging over the next few weeks before I take the next step; assuming we get some breaks in the clouds that is. Do my initial choices seem reasonable and how would you do this different, assuming a max budget of £2k (looking to buy new, not second hand). All views / comments welcomed. Cheers, Dave
  19. Now this is the way to ring in the New Year. I took advantage of our unseasonal like crystal clear skies we are enjoying and forgo the traditional festivities and spend it under the stars. I was finally able to make another dream come true and at last image the Orion Nebula with my iOptron Zmount and AT65EDQ. With an amazing 5 hour session that wrapped up at about 3 in the morning here's the results. Let me know what you think of the processing. 15x5 seconds, 15x30 seconds, 15x120 seconds, 15x300 seconds. Each series went thru DSS and then blended together in PS4 and tweeked in LR4. The ORION Nebula by Leveye, on Flickr
