  1. Best solar image I have seen. Feels like you are flying over the Sun!
  2. Never seen a Lunt 60mm for £1150. At least not in the UK. Perhaps I didn't get a good deal second hand after all.
  3. Lunt have a 5 year warranty that they honour even if you are not the original owner. If it's in warranty I would not be concerned about buying secondhand.
  4. The way that prom loops over from the disc is awesome. Looks best on the inverted false colour to me. Very nice work.
  5. Went out for a bit. Looked very clear between the clouds but the seeing wasn't good at all for me. Jupiter was no good at higher power (x150).
  6. Oddsocks that is brilliant. Just what I wanted. Nice one. Thanks Didn't want to go down tube ring route when it already has a clamshell.
  7. Evening all, I need some help attaching my Lunt LS60 to my mount. I have a HEQ5 so I want to use a vixen style dovetail. Lunt offer up this but its a bit pricy: http://astronomia.co.uk/index.php/accessories/solar-accessories/lunt/lun-ls100ps.html I understand I need some specific 1/4"-20 screws but what I am not sure on is whether or not I can use the 15cm skywatcher dovetail: http://www.firstlightoptics.com/dovetail-bars/skywatcher-dovetail-mounting-plates.html It looks like the mounting surface should be flat and the 15cm looks flat. What I ask not sure on is if the hole centres will be the correct distance apart assuming I should use two screws. Any advice on what would work and where to get these screws from would be appreciated.
  8. Thanks for the answers guys. Sounds like the window is 7-12 days then but the spots themselves are very dynamic. I started trying to work it out myself by finding out how fast the sun rotated (27 days at equator - 31 days at poles), including the earth orbit, and then trying to find out if the earth orbit was in the same direction as the suns rotation. It turns out everything should rotate counterclockwise (Venus and Neptune being exceptions). At this point I decided it was too complicated and thought I would ask you guys for some practical experience. I hope this one holds out until next weekend and that it isn't as cloudy as it is here now in Derby. I can see why solar viewing is addictive and I haven't even started!
  9. Yes! New solar scope should arrive Monday to start getting a good look of this. Excuse my ignorance but how long does it take for us to see a sunspot move across the disc face assuming we can't see it at highly tangential angles. Also do they disappear before moving across whole disc (I guess they are very active). I am new to this solar stuff!
  10. They are some nice setups there so plenty of options for me to consider. What I am most confused about is the mount. I was originally thinking az4 but now looking at a giro II deluxe. I can't find what a giro III is. Do you think the giro II / III would be better than a giro mini considering I only have to lug it out the back door. Also the altair sabre looks nice but not sure how that performs. And then there is slo mo controls on the Skytee 2. This is all very confusing....
  11. Hi all, I am after some advice of people's experience on a grab and go mount for a Lunt LS60 (or other small refractors at lowish mag). So far considering vixen porta II, AZ3, AZ4 with aluminium legs (I already have steel ones from my HEQ5). Not sure what will work best in terms of lightness for set up speed, slo mo controls, etc. I was set on a mini porta until I read some reviews about lack of quality. AZ4 seems a safe bet? Any advice greatly appreciated!
  12. That is going to be immense. Can't wait to see the results!
  13. Very nice. I was thinking of getting one of these to get into CCD mono imaging. Did you get the focal reducer? F4.72 sounds good. What camera will you be using with this?
  14. An impact with a planet! It is fascinating and brilliant to see it in this capture. Well done!
  15. This is exactly what the polar realign function on the SynScan controller does and it works wonders for me so I think it is sound logic. One word of caution...adjusting the alt bolts with nearly 20kg extra on the mount could lead to problems.
  16. Had a great night on Saturday at 9pm M31, M57, M27, M13, M92, double double, alberio double...all awesome in 120mm
  17. The Delos 12mm sounds ideal and useful for some wider views if needed
  18. Is this really a contender for one of the best EPs ever made? I am looking for an EP to sit in beyween my 12mm and 35mm Tele Vues. i already have the 12mm T4 which i will say is fantastic but i do not doubt that it would be beaten by the nearest Delos and 13mm Ethos. I was considering either a 20mm nagler, 26mm Nagler or this 22mm nagler. i have heard raving reviews about the 20mm and 26mm. Perhaps the 21mm Ethos would pip them again but that is ludicrous money. I would be interested to know the thought of some that have used a few of these EPs.
  19. I have the 12mm t4 and love it. It's very immersive. However it is very heavy and I can't reach focus using it in my MN190 with extension. Therefore I am considering moving to the 13mm t6 so it's par focal with my 9mm. There was a 1mt4 on ABS recently for a very very good price.
  20. That is a great start. I have found that dropping the ISO down gives a better image with more colour. Try ISO 800 or 400.
  21. The thing that took all the pain away for me was the polar realignment function. If nothing else it tells you how good a job you did of polar aligning. Sometimes I am miles off and sometimes it's just a tweak. Also if you set up in a similar position each night just mark all the leg heights and feet positions (even by eye) and then you will never need to adjust much. A word of warning on the polar realignment...you now have the scope and counterweights attached so need to be careful with those bendy altitude bolts.
  22. I do use a higher power eyepiece (Nagler 3-6mm zoom) when using my mounts polar re-alignment function. A trick I use is to defocus the star so that most of the FOV is taken up. I can then use the sharp edges to align against the edge of the eyepiece FOV. Not sure if this is more accurate but it works for me.
  23. Skywatcher 120ED either Pro or Equinox is a good all rounder. It's a reasonable aperture with nice optics for visual, relatively low budget and ok for AP. I love mine! However for AP you need at least the HEQ5 and this set up is not light. Tried to carry it set up all at once and nearly had a disaster. Most of your ideal requirements are trade offs unfortunately.
