  1. Hi Just ordered a QHY PoleMaster for my HEQ5, Modern Astronomy has sold out so they are proving popular I think. Should get mine towards the end of the month according to Bernard. Thanks Sent from my iPad using Tapatalk
  2. Hi Does the Atik Infinity software work with other cameras such as the Titan or 414ex? I researched this a bit and thought it didn't. Would be great if it did. Thanks Stuart Sent from my iPad using Tapatalk
  3. Hi I use the adapter plate from FLO and it works well. I use 4 bolts to attach this plate to the dovetail and its rock solid. It's a good little unit., I bought the ADM mini guider thinking it would be a step up from the SW unit and its not, if anything it's a step down. The ADM unit is really well made but has some design issues. I now use the SW one all the time. Thanks Sent from my iPad using Tapatalk
  4. Looks really good. ST80s are great. Just out of interest how do you find the 2 cell variable polarisers at high mag? I have the Celestron ones and they produce horrible astigmatism at high magnification. I assume that the single axis polarisers are based on some form of aligned polymers chains and this produces the astigmatism?? Thanks Sent from my iPad using Tapatalk
  5. Hi I think the Civil Aviation Authority also have laws about using any lasers within a certain distance of an airfield. I live very close to a army base that run regular Chinook manoeuvres right above my house. Using a laser would be a bad idea I think..... Thanks Sent from my iPad using Tapatalk
  6. HiBoth great pictures, the top one is the Sony I guess, lots more detail to my old eyes. Also the diffraction spikes in the lower image gives a bit of a clue.... Thanks Sent from my iPad using Tapatalk
  7. Hi Not tempted by the 414 instead of the 314, it's not much more money but the new sensor seems great with increased sensitivity over the 314. Thanks Sent from my iPad using Tapatalk
  8. Hi I had something similar on my Titan and it was the USB cable, the image was grainy and noisy and also had bands. I changed the cable and it was fine. Try using it during the day and focus on a tree or something in the distant, you need to turn the exposure right down to its minimum but you can see things. It's much easier to see things in the day. Thanks Sent from my iPad using Tapatalk
  9. I'm wondering the same, my 414 / Titan downloads it's data pretty quickly so it wouldn't take long for a real time stacked image to build up. I hope Atik don't restrict the new software to just the New Infinity...... Stuart Sent from my iPad using Tapatalk
  10. Hi I have an old True Technology filter wheel that takes various filter carousels including an 8 way 1.25" and 5 way 2". The one I have can be operated via a PC or via a standalone hand controller. Not everyone liked the True Tech wheels, they were quite expensive and had some quality issues but mine has always worked fine. One nice feature is that the unit is hinged so you can change carousels without taking the filter unit off the telescope. You can't buy them anymore (I think) but one might come up second hand.

  11. Hi Did you take apart the objective lens? I think the inside lens looks symmetrical buts it's not, if it's the wrong way round the convex surface of the inside lens can just about touch the concave surface of the outer lens and this can produce funny effects. Just a thought. My ST80 is a bit like yours with an upgraded GSO Crayford. I have a flip mirror as well. Thanks Sent from my iPad using Tapatalk
  12. Hi Personally I think the prices are reasonable. Don't forget that Atik etc are very small companies with tiny volumes. They make niche products for a very small market. Yes I suspect the bill of materials to RRP ratio is high but that's no different from other niche consumer products. Luxury watches are really bad, the companies make them for nothing (10s of €s) and sell them for hundreds or thousands. People have to make a living and I bet if went to the Atik factory the car park wouldn't be full of expensive cars.... I don't feel ripped off when I buy Atik products and I will continue to buy their cameras......now do I buy a mono or colour Infinity this weekend??? Thanks
  13. I used to go to HK on a regular basis. Fantastic city with fantastic people but I must admit it wouldn't be my first choice location for housing a scope like this. The pollution, both light and smog is quite significant at times. Hong Kong Island and Kowloon are particularly bad for light pollution. It might be better in parts of the New Territories but then the smog rolls in from Shenzhen..... Stuart Sent from my iPad using Tapatalk
  14. Hi I have ADM Mini guider which is similar but a bit smaller. It's ok but not fantastic. I bought it thinking it would be a step up from the Skywatcher guide unit but it's not. I have to say that in my view the Skywatcher unit is better. I have made some minor mods to my Skywatcher unit and I'm very happy with it. I use it in preference to the ADM unit. The ADM unit feels robust and looks well made but actually it seems to have play in it even when locked down. The tolerances on some of the machined parts seem a bit poor (particularly on the up/down) so it can move a bit even when locked. The origin of the slack seems to come from steel pivot pins that fit into some drilled aluminium supports. The slack is counteracted with some big springs which effectively push to remove any slack if that makes sense. I suspect I'm being very picky about this as the springs that push everything together (and remove any play) are quite powerful so I suspect in reality it won't move at all but the engineer in me doesn't like the fact that even when locked it can still move. I did buy an early / ex-demo from FLO at a reduced price so maybe the later units have improved a bit on QC. Serves me right for trying to save a few quid I guess. I think I will do a little design mod to remove the slack at some point. Thanks Sent from my iPad using Tapatalk
  15. Hi Yes it's the F7 one, I like it. Altair triplets (i.e. GSO) seem good, The Sky at Night magazine liked it about a year ago. To be honest it's not that new!! Too many distractions for me with work and a young family. This season I will find more time. One day I will buy a Tak as well. Thanks Sent from my iPad using Tapatalk
  16. Hi I have the Altair Astro 60 mm triplet, I like it. Well made and visual very good. I've not done any imaging with it yet but will this season. With the Altair reducer it's a good wide field scope on paper. Let's see. A lot cheaper than a Tak...... Thanks Sent from my iPad using Tapatalk
  17. Or the Titan? At least the Titan has an ST4 port as well. Also doesn't the 314l+ have an ST4 port? This new camera will make a great guide camera with that CCD. Not sure I would buy it just for guiding but as a video camera sometimes used as a guider?? I'm interested. I'm guessing it will cost around the £600-700 region.

  18. Looking good, I've recently bought a 414 mono so a nice OSC camera with the same great sensor like this will match perfectly! Just need to find the money now...... Stuart Sent from my iPad using Tapatalk
  19. Hi I have one and they are ok, as already said made of plastic but they feel solid enough. One thing to remember is that you need to align it such that you don't breathe over the other eyepieces, if you don't then when you come to use them they are all misted up. Apart from that it works well enough. Stuart Sent from my iPad using Tapatalk
  20. Thanks Nigel, The last time I did any real plastics was in my degree and that was a long long time ago. I've been a metallurgist for the last 25 years. I do remember that all plastics undergo visco-elastic deformation but couldn't remember which ones were good / bad etc. I assumed that HDPE would be good as that used to be the material of choice for hip implants etc. Thanks for the clarification. I think I'm coming to the conclusion that I replace the existing nylon ball bearings with new nylon ones. Stuart Sent from my iPad using Tapatalk
  21. Thanks Alan I tend to agree, the mount has done well for a quite a few years and is only just starting to go a bit notchy so I'm tempted to replace like for like. I think I can source some HDPE ball bearings and these will be a bit better than the Nylon ones - I think!. The Skywatcher grease is good, very sticky but does its job well and it stays in place which is important. The use of this grease is design intent and not cost saving in my view.

  22. I agree Olly - and I am one of those people with a degree (and PhD) in Materials Science, although I'm firmly a metallurgist. Plastics are some weird non engineering cheap material to me!! When I see astro adapters made on plastic 3D printers I just cringe, they look weak and flexible and not at all suitable for the job. In my old job I was asked about a material designation on a drawing as the engineer had defined the material as SFP. When questioned about the acronym the first word was "Some" and the last word was "Plastic". The word in the middle can't be published on here..... In general this sums up my views of plastics. However, I think in this case Celestron used these Nylon ball bearings to ensure that the aluminium race wasn't ever damaged during use. I don't think it was a cost saving measure I think it was genuine design intent hence my original question. Thanks Sent from my iPad using Tapatalk
  23. I suspect it will be a high silicon casting alloy so something like ADC12 or A380. It won't be heat treated either so it will be very soft I suspect. I could analyse it at work if I really felt the need...... Thanks Sent from my iPad using Tapatalk
  24. Thanks, good info.. Any sign of wear at all on the aluminium race? Do you run the mount as standard or on a wedge? I'm not too concerned about the standard operation as the load on the individual bearings will be even and will be very small. It's the wedge operation that I'm concerned about when the uneven loading might causing the denting I'm worried about?? Stuart Sent from my iPad using Tapatalk
