  1. That's great, many thanks Adrian
  2. Thanks Mike. It was all a bit "last minute" and the battery on the Canon 600D needed charging, but you're right I need to do a comparison. On the whole the 600D works well, but is noisy when the sensor gets warm.
  3. Hope you don't have to go via M42 J3 as the roadworks are causing big delays I didn't perform a stretch, so I'm wondering if that was part of the problem
  4. Mine is 242mm, F/4.8 https://www.firstlightoptics.com/guide-cameras/sky-watcher-evoguide-50ed-guidescope-zwo-asi120mm-bundle.html
  5. Thanks. I only use the ASCOM derived Unity settings (G120, O30) last night, so optimising this would be a good start Many thanks for your detailed reply. I agree, I'd have expected the additional light gather to have compensated for the slower speed of the ED120, which is why I was surprised. There was no dew on the lens and yes the ASI120 was in 8 bit mode. I'm new to APT and it's complex compared with my previous BackyardEOS. I need to do some more reading Thanks, I will. Only just noticed your location. You can't be too far away from me, we probably share the same light pollution!
  6. I’ve recently purchased a ZWO ASI294MC-PRO and last night was first light for this on my SW 120ED. Conditions were not ideal for imaging, but to familiarize mysef with the camera I setup a comparison with the SW 50mm guidescope / ASI 120MM Mini using Sharpcap and APT. I had great hopes for the 294, especially in terms of sensitivity, but I have found that the 294 appears far less sensitive than the 120MM. As an example, M57 using the 120MM with a gain of 54 and an 8 second exposure clearly showed the object and a multitude of stars. Whilst the 294 on the 120ED showed a much fainter M57 with only a few stars present. Only by increasing the gain on the 294 to >500 were the images comparable, but this then resulted in much greater noise. It was a similar situation with M51. Using APT with a 2 minute exposure, there was no sign of the object using the 294, but it could be seen with the guidescope/120MM. I’d be grateful if anyone could provide advice on this or indeed guidance or a link for initial settings to use with a 294. I realise that the migration from DSLR to a CMOS/OSC is a steep learning curve and so I’d like to eliminate user error before contacting FLO about a potentially defective camera. Many thanks Adrian
  7. I tried using a Logitech Gamepad F710, but found that the wireless connection was frequently lost, usually part way through an observing session. I later read a report that buttons on the F710 can be susceptible to moisture. I now use a wired gamepad, which although less convenient never looses a connection. Adrian
  8. I'm in the same dilemma. I came across this insurer, but I have no experience of it https://www.gloverhowe.co.uk/astronomy-insurance/ Adrian
  9. Turnbuckles at an angle too. In use for 4 years and no problems yet Adrian
  10. The ISS can be picked up with very basic equipment. I managed to hear Tim Peake when he was aboard using a handheld Baofeng UV-5RA.
  11. Just found out that Andy "Astronomiser" has stopped doing Canon DSLR mods from 16th Sept. I'd like to get my 600D modified. Does anyone have any recommendations? Microbe
  12. Thanks. Opted for the CR1 in the end, and as it was on offer at FLO I put the saving towards the DC motorised attachment. It works well, apart from failing to reach focus with some eyepieces, so needed to buy a focus extended, but a big improvement on the stock SW focuser.
  13. I would like to replace the stock focuser on my SW 200P and have been looking at the Moonlite options. My aim is also to have this motorised at some stage. With this in mind, is there any advantage in the CR2 over the CR1, particularly as there is a £110 price difference which could be put towards the motorised focuser option. I'd be interested in the thoughts of anyone else who has had this dilemma Thanks in advance Adrian
  14. Fair point and I did think about that, but the supply is via an RCD and the dryer will be in a box until needed. I was put off by the 12v option by the current rating and the PSU/battery needed to supply it.
  15. Another user of the ECO DD122FW. It's only been in use for 2 months but has been very effective in removing post-observing dew and keeping the humidity at at acceptable level. The supplied drain pipe is a bit stiff and so needed some warm water to mould it into shape but is otherwise ideal. I was concerned about the electricity usage, but on its current setting a plug-in monitor has measured between 0.6 and 0.9 KWh per day which is far cheaper than damaged equipment Regards Adrian
