  1. Interested to hear out you get on with e ink tablet. I was hoping maybe an OLED based tablet would be close to simulating the red led screen of the Nexus….
  2. The joystick removes the need to keep the web front end running to control the AZ100 via a wireless gamepad. The remote however does not have a screen. I would of liked the option to select a target and perform two star alignment via the controller. A bit like the Pegasus controller: At the moment the other option is a Nexus, that has the advantage of less screen light as the red led can be made very faint.
  3. If anyone with an interest in the AZ100 has gone to the Practical Astro Show maybe they could tell us about this upcoming AZ100 remote control. Thanks
  4. Is is still one more thing to do. it's a trade off between compactness for the aperture compared with a Newtonian and adding shield to handle the dew build up.....
  5. Since this thread is so old I would how many who posted have still got there SCT’s?
  6. I sold a Vixem SD103S to fund a C11. Should I have kept the SD103S, probably, however I sold it because I thought it would keep my wife happy and the C11 was actual sold to keep the owners wife happy. Maybe we need a thread title how many scope have you sold or relocated to keep you partner happy?
  7. Quite a good price, that’s cheaper then what is being asked for a Stowaway new at Skypoint.
  8. Plenty of space in the garage…. As far as hiding scopes is this why EP’s are bought so much as so easy to hid? 😃
  9. I would select an AP Riccardi-Honders, https://www.astro-physics.info/index.htm?products/telescopes/305honders/305honders I could then use an NVD @ F3.8 in prime mode which gives a sharper image. Since the above scope is no longer made I'l have to wait for Lockwood's F2 Newt-Cassegrain (best words to describe it) you can read more about it here... http://www.loptics.com/articles/WSP2024/WSP2024.html It looks like a Newt, however has a custom multiple optic corrector as a Paracorr cannot deal with the speed of the scope. I'm sure not really a new design as the military have had scopes like this for some time.
  10. I would go with a LZOS 105 mm, even if it weighs twice as much as a Takahashi and much more than TV85 mm. The unique selling point is the speed for use with an NVD, at F5 using a compressor it makes for a bright image and without the NVD the large exit pupil helps with using a filter with a glass EP. Under a dark sky the boast in contrast is amazing. AP compressor below, fits inside the FT3545. The scope compressors to no more in length then the TV 85 mm and I can use on a AZ75, thats the only part that makes the scope not flyable with. @DirkSteele surely if you need weight reduction a Stowaway 92 mm would fit the bill 😀 in stock here however it’s nearly the same price as a 130 mm LZOS. If I was not needing portable the 130 mm version would be my first choice, but there is something just right in size etc with a 105 mm scope.
  11. I was wondering if the Rowan control box could be extended to host FinderPi plate solving. Seeing as the control box looks like a Raspberry Pi and things has moved on, this open source project allows for plate solving on a RaspPi https://github.com/brickbots/PiFinder I was thinking if the software runs on a Pi and could be hosted in the AZ control box all that is needed is either a hand controller with a screen or maybe the Rowan planetarium software is extended to support plate solving feature. The main trick is a camera and gyroscope needs to be added and connected to the controller box via a cable. The up shot is push to with plate solving and hopefully no need for encoders. On the AZ1100 it could hopefully drive the motors. No need to level the mount precisely or realign at all if the scope/mount is moved around the garden.... Could we have plate solving running on the control box is the question?
  12. Three scopes in total: LZOS 105 mm/ @ 6.25 (Very sharp, folds up very small) A larger LZOS 130 mm @ f6 And a C11 before it was wrapped with insulation. I seem to have a lot less scopes than other people posting in this forum., what scope next? I have a suspicion that any larger than 130 mm APO's cannot really be pushed to their limits due to the seeing that the UK skies support, maybe a slower 130 mm? A 16" DOB, well I could wheel it out the front, however not out the back as no access.
  13. I'd agree 😀 Also older threads on this subject do not take into account advances made. A takahashi DZ or Agema Optics are for effective purposes are giving the performance of a triplet with the cool down properties of a doublet. 125 mm seems to be where most of the action is, also consider this scope which has a Strehl measured in the green of at least 0.95 https://astrograph.net/epages/www_astrograph_net.sf/en_GB/?ObjectPath=/Shops/www_astrograph_net/Products/AGTEC125F78
  14. Yes, you can find more detail here https://telescope-optics.dish-cable.com/eye_intensity_response.htm on a separate note if you’d re looking at planets then a 5” APO would fill a gap, none of your scope would have a MTF to match. A C11 on planets gives a mush view compared to a APO. Just a better light bucket for DSO…
  15. I think the C9.25 and the C11 are the same faff to set up etc, maybe a little weight saved. I have just put some insulation on the C11 to see if that helps with stopping currents forming in the tube, cloud and moisture as stopped any observations so far. If you are using visually I would think of another mount then the AZEQ6, I had a SXP2 which carries more weight and weighs a lot less but was such faff to setup compared with an AltZ I moved to an AZ100. Maybe focusing on the mount might also make you observation a bit easier... Also, C11 has a huge focal length that gives a huge image scale. Thats not a feature you will get with a refractor.
  16. Well I'll put my 2 cent in as an owner of a C11 and various APO's. The last time I went out, although the sky looked like it could support the C11 the moisture content in the air was high. Meaning getting the dew heater out, a C11 should always be used with a dew shield even in summer to keep the correct as clean as possible. I passed on the C11 and instead pulled out a 105 and 130 mm APO.. Again, the previous viewing night I enjoyed was away and I was in a bit of a rush to get to the club night after my daughter had drifted off to sleep. Again I went with a 105 mm APO as that meant transporting less equipment. Don't get me wrong when it's a good night and I'm looking at DSO's the C11 is brilliant, however other nights even when I'm not looking at DSO's or other faint objects then for multiple reasons and APO every time. The C11 is a secondary scope due to it's size...
  17. Has anyone got a AP-Z and a AZ75, any comparison at all. How does the AP-Z handle a 2" diagonal and a heavy EP?
  18. I have a LZOS 105 mm @ f 6.25. As many have stated it provides super sharp, high contrast views when the cloud allows. Does it give up some aperture to a 130 mm version, of course however there is some thing about the sharpness and the brightness of the lens to the eye that makes you not want to give it up, I do not know why the previous owner did…
  19. Did you ever try thermally insulating the C9.25? I have a C11 and use it as a light bucket for low powered views. For high powered views I've never had a none mushy night on planets.
  20. You have a 185 mm finder scope, finally it would get some use! 😃
  21. Well the AZ75 is 4.5 kg and using a carbon tripod around 8 kg in total. The main difference is a 130 mm will work quite well on it. The only reason I did not take the 130 mm was the child seat in the back and I was already late. The boot was full of a dog crate.
  22. You much does the TMB 115 weigh? The 105 mm with a FT3545 is around 7 kg, however compacts to 495 mm long... I took it out to Albury cricket ground last night and although the moon was out managed to see some nebulosity around Orion, with no filter and a APM 100 mm UFF in. Last night was also colder then expected, the Kruppax tube kept the dew away! To be honest it's all about how much mount can be transported, the scope choice then flows from that.
