  1. I understand you can store different calibrations for different scopes in SS so adding a standard Vixen foot to your C6 would provide a solution, and the duel foot to your refractor if you need an RDF as well.
  2. You may already have seen Steve Tonkin's site but if not have a look here http://binocularsky.com A lot of very good advice and some reviews as well.
  3. You could try a double finder scope bracket like this https://www.telescopehouse.com/orion-dual-finder-scope-mounting-bracket.html or a similar one that sits flush to the scope. But that means you will still need to use the other smaller fixing bracket that comes with SS and no gaurantee there is enough real estate around your scope for them to live side by side ,could be tight. Yes it's a pain going from one bracket type to the other but you could add a standard holder to the C6 tube instead of using the bigger Celestron one to hold your SS in place. That would bring some compatibility across the two scopes assuming there is enough room for the duel holder on your refractor.
  4. You can practice alignments indoors ,doesn't have to be accurate just use a star and point to the general position followed by whichever auto 2nd star you choose, it helps to get a feel for things. Was looking at my notes so input is Longitude W ( or east depending) followed by latitude N in degrees minutes and seconds. UTC 0 and yes to daylight savings until the clocks shift back next month. Your coordinates will be sound for about a 50 mile radius but I admit I change mine even if I go 5 miles up the road! Just ensue your date format is correct US format and time is accurate. Put a decent distance between your 2 stars and choose ones above 30° and below 70° and preferably not at the same altitude. There is an android app called map coordinates that gives accurate info as well as the aforementioned Synscaninit. Skyalign needs 3 bright stars,I believe the first two are the main alignment and the 3rd verifies the other 2 are correct. So yes you do not need the names of the stars but it only works if the stars chosen are actually in the computers database. I found Skyaligns success rate to be about 40% whereas auto 2 star about 95% , further to that Skyalign is no more accurate than auto 2 star once aligned.
  5. Or this http://www.latlong.net/ You want decimal degrees I personally found auto 2 star the most reliable.
  6. recommeded eyepieces for 150pds

    My instinct also is coma at the edges of the mirror rather than astigmatism in the EP so your suggestion is probably on the right track. I just haven't been able to test enough or compare to other EPs. I have a SW coma corrector also to test plus a bunch of ES EPs, and a Nexus DSC and AYOII all waiting to get out the door! Interesting your experience of the 8mm, my one does better than the ES82 6.7mm unless seeing conditions are very good then the ES pulls away.

    Andy, I have been using BSTs in my 6 inch F5 reflector and the performance is pretty decent. Have 8, 12, 18 , 25 and of those in all my scopes the 18 is the best performer. On mine the view does show oval stars about 10/15% around the edge of view but I don't know if this is coma or astigmatism. It wasn't to me objectionable as the centre view was really quite good. The 8 mm on Jupiter was better than I expected, nice bright contrasty views with good detail. The 18 is a lovely EP for general DSO and big globs. The reflector is fairly new so not fully tested yet but my initial thoughts are for the money the BST are punching above their weight. They do very well in my C9.25 so obviously in F5 it's more demanding but as mentioned from what I have seen so far I doubt you will be disappointed . You could do a lot worse! They seem to me to be one of the top performers in this price bracket. Am in the process of upgrading to ES as I now have my scopes of choice but that's not a reflection on the BST, more about having a more suitable range usable across 3 scopes.
  8. Full Frame APS-C "crop factors" etc.

    I am just trying to remember the last time I saw a flying teapot and the circumstances that led up to it
  9. Nexus DSC First Light

    That's encouraging Clem, nice set up. There is a clear sky threatened tonight so hopefully might get first light with mine, might give the Equinox 80 a run out. Need to test some new EPs as well!
  10. I know ,was hoping someone found a way around it! AZ132 specifically mentions Evolution from what I can see 😁
  11. Hi Janet, The Astrozap gear is pretty good you won't go far wrong with that it's also what I use. I made my own dew shield and then attach a heater tape around the scope and plug it into a dew controller box. That does need power so you will also need some kind of battery as dew controllers cannot be powered from the Evo mount. ( Please someone prove me wrong! ) I think your peace of mind plan with Amazon is a good idea, the returns is one thing they are very good. Yes what a pain about Photobucket, many ruined forum threads thanks to them. I will attempt to log in tomorrow and see if I can retrieve the pics and if so send them to you!
  12. Hi Janet, Welcome to SGL! Thank you for your kind words I am pleased the review helped you in your decision. I think we have all been there when buying scopes trying to find the right one at the right price and also one that can be versatile and will get used. That last point is so important as observing for me at home is not really practical but I have a few dark sites nearby I can use and taking the Evo out to them is not too much trouble at all. It is certainly a scope you can grow into and there is no end of help on here if you get any issues. Of course there will be a learning curve but once mastered the big Evo will open up the heavens and show you some spectacular sights. After a while you will gain an idea of what objects you like looking at and then tailor things to suit your interests. So this moves it onto your question about eyepieces. Personally it may seem tempting to pick up a complete set for the extra 220 dollars or so but for that money you could get 2 or 3 intermediate and better quality EPs. I am no expert on EPs and watch very carefully on here for other peoples advice especially as I am about to upgrade mine so it might be worth asking the question here or doing a search. Certainly the set will get you on the way for a time but as you hone your interest you will aim for EPs to complement them. One thing to consider is a dew shield and maybe some heater tapes or indeed a dew shield that is heated, These SCTs are dew magnets!. No one is going to flame you for jumping in like this, if it does not work out you can sell and adapt to something that will work for you so do not get bogged down by your choices. Read as much as you can, sometimes between the lines as well and remember just about everyone here has bought and sold a scope after finding it was not quite right! This hobby is great fun, sometimes frustrating, usually always expensive but very addictive and rewarding. The Evo 9.25 took my own astronomy to a whole new level and although I have smaller scopes for different situations usually time related when the right moment presents itself it is the 9.25 that comes out for the very memorable evenings. Look forward to hearing about your adventures.
  13. If it's an Edge on the Evo then optically it might be better than the standard one on the CPC as Edge optics apparently show sharp stars to the edge, plus it should cool quicker thanks to the vents. It may not be an overall large difference however. Consider if you might want to add a focal reducer to the Edge as I think they are a lot more expensive than the standard ones for a normal 8 inch SCT. The edge scopes are more geared up for imaging so if imaging is not your thing then the CPC might be the way to go. Also if you go the Evo route and you want to offload Starsense then the HC goes with it as Celestron do not put the standard HC in those packages as well as the Starsense one. Mount wise the double fork of the CPC is likely to be more stable although I have never used one. I have used Evo 9 and 8 and can tell you stability is not really an issue, damping times are pretty good for single fork. The CPC has built in GPS which may be useful to you as it will set your coordinates and time. The Evo has the luxury of a built in battery and WiFi plus a dimmable red light for the tray. Motor wise I would not expect them to be vastly different in operation, the Evos I have used have tracked objects wonderfully well and Starsense gives very good GOTOs and saves time aligning. The other thing about the mounts is that with the CPC I'm not sure how easy it is to separate the scope from the forks, it seems people mostly leave them attached so you would be heaving the scope and mount together. The Evo comes apart very easily and also takes my 80 mm refractor, something the CPC probably can't do without a few mods. So not a great deal in it between the 2 you list, but for me if I was choosing between those two and considering that your trying to max out observing time with easy to lump kit and short set up and tear down times then overall the Evo with the Starsense just starts to edge it ( no pun intended! ) It takes about a minute to tap in coordinates and time and if your observing from the same place then you can save your coordinates into the custom site of the HC.
  14. Brilliant ,thank you Clem , yes your about 15 minutes away and I would like to see that set up. Let me know when you have it all set up and we can arrange something.
  15. Looks good. I have Nexus DSC, but where in UK can you get an M2?
