  1. No not really. I think I have 180 seconds with a 10 second delay. Then set it to repeat 100 times
  2. I use this one and it works with the 400D and 450D (and many others) when set in bulb mode. https://www.amazon.co.uk/gp/product/B01GHHBNU0 They are all very similar. I can easily get 5 minute+ exposures from it but normally limit it to about 3 minutes.
  3. I have no complaints with my ZWO ASI183MC and ASI183MM with the apertures/focal lengths I use. I too don't like the square format of the 533 despite its promise of zero amp glow. One thing to bear in mind with the 183 is the amp glow but it can be calibrated out completely. Also keep the gain down to default 111 or even 53 and it is more than sensitive enough. The 183's from ZWO also have AR coatings on the aperture windows so you don't get any internal reflections.
  4. I replaced mine with 2 fully threaded M10 x 75 long stainless steel hex bolts as I found that my cable harness would catch on the rear Skywatcher adjuster. I adjust the bolts with a 17mm combination spanner which is kept on the mount legs with a rare earth magnet. I ground the ends of each bolt to a dome as per the originals At my latitude of 53 degrees north the length of bolt is ideal and doesn't protrude too far. No more fouling of cables. Not at all difficult to adjust either.
  5. When we do get longer spells in the UK a lot of people complain they need sleep I used to be like that but now leave the scheduler to do operate the gear while I'm tucked up in bed.
  6. I agree with Kirkster. Observing/imaging nights are few and far between in some areas of the UK so you have to make the most of it. The longest recent spell of imaging I've had was about 12 nights September 2020 (in the period from 13/09/2020 to 27/09/2020). Some nights in that period were poor the rest were great. However it has been poor ever since. I think there was one Saturday night in October so far that has been ok but I wasn't imaging that night. Frustrating for sure but deterred? No chance.
  7. I run Astroberry on the PI4 which is located local to the mount/telescope. It runs the INDI drivers for the gear. It is connected via a gigabit ethernet connection to my main network. I then run EKOS/KStars on a PC or MAC connecting to the PI4 in EKOS remote mode. I have set it to send the pictures both to the PI and the PC. EDIT I've just timed it and a download of a 40MB file from PI to the PC are 0.5 seconds using SFTP.
  8. +1 for ETGuuds and Lindy. Both available from Amazon. However I recommend keeping your cables as short as possible feeding into a powered USB3 hub actually on the mount or pier. Then use a single USB3 repeater cable to feed to your computer if it is remote from the scope. You won’t experience any drops that way.
  9. No idea as the manual on the SW site for updating the firmware says and shows plug 12v into the controller. Mine does not have a 2.1mm socket on the controller. It looks like the manual is out of date. Unless you are having issues I would leave it alone as the firmware only seems to update connection to the GPS module and fix some minor bugs.
  10. I agree entirely with Padraic. A mount like the HEQ5Pro (belt modded if possible) would be a great match for the Espirit 80 and would be well within its imaging load capacity.
  11. Yes it does but if you plan to point in the other direction the IDAS also does a stirling job.
  12. I have the Altair triband and find it is reasonably good both with DSLR and dedicated Astrophotography OSC camera especially in Ha. However it does have issues with OIII band and I find it a touch too wide in bandwidth. It covers the HII band in the same green spectrum. The quadband is for less light polluted skies and may be good for you. I’m in Bortle 7/8 hence the tribander. My favourite filter for OSC or DSLR is without doubt the IDAS D2 which blocks out LED lights as well as traditional light pollution but lets through most of the RGB. It produces far better pictures than the Altair Tribander. However use the Ha from the Altair as a lum layer with the RGB from the IDAS and it really makes images pop. However I also do mono and have Ha, OIII and SII filters in the armoury. UK skies are not ideal for mono due to the multiple filter exposures required, unreliable cloudy skies, rain etc. but when the skies are on form mono is superb.
  13. It increments up by 1 whenever someone likes one of your posts or comments. It's a count of how popular your comments are.
  14. I know what he is talking about Hadyn. I have the scope upside down so the rack is on the top. The focuslock screw does not foul anything then. I also have an autofocuser fitted to mine and that uses the screw hole previously used for the focuslock to secure the bracket to the scope.
  15. I’ve never needed any spacers to enable my WO ZS73 scope to balance when using a DSLR or a dedicated astronomy camera. I’m not sure what you have heard.
