  1. I find it's the loosening after say all day mounted for solar that can be an issue ! I'm looking at trying different saddle options as i,m not entirely satisfied with my ADMs ... I'm thinking about Geoptik or even that Farpoint one looks good. Brian
  2. Just catching up with this post John on the Rowan saddle you could presumably just use an Allen key if space was tight ?
  3. Nice for a first attempt, and yes this can only and will improve ☀️ Brian
  4. Great looking Mount there John 👍 and as the saying goes “everything comes to he who waits” .... well most things 😀 Brian
  5. I think that is about the daftest thing I’ve ever seen with regard to solar astronomy 😂 Brian
  6. It’s a non-critical part not sure of its purpose either apart from perhaps being able to mount another finder ? Rem to have the tuning white line mark at an directly opposite centre position to the LED and then try 1 or 2 clicks anti or clockwise from there / in experimentation. Brian
  7. Externally mounted ERFs normally have a 5 degree tilt , internal 🤷‍♂️ none at the the diagonal however 🌚 Brian
  8. I think I'll be spending some time tinkering with my skytee II this winter as it needs some attention , but would much prefer one of the AZ100s. Brian
  9. The best option is to go for an externally mounted ERF though Mark as on the better days you will experience some turbulence within the OTA using an internal ERF. The Quarks by themselves up to about 100mm are fine as the highly polished mirror finish of their BF reflects most of the energy , a member on another forum managed to partially melt a plastic drainpipe via this process. I think most importantly though they are best not used with triplets , cemented or oil spaced lenses without an external ERF imho. Brian
  10. The 35nms are mini Baader D-ERFs Exactly the same coatings so no probs Brian
  11. It all comes down to experience & trying as many different set ups as possible. I 've 14 years of HA experience and I'm still experimenting , so could write a book on it The Scout like the quark but unlike all other configurations has its BF to the front and the etalon to the rear giving a 16mm window at the diagonal , it is a very convenient package as is almost grab n go , however like the quark is quite seeing dependant , EP selection , tuning and focusing are critical also. If going down the Quark route then a 2" Baader 35nm filter is all the ERF you'll ever need well up to 150mm and is much more effective than a standard ur/ir cut. But for your first foray into the HA world it's hard to beat the PST ! a common misconception is that it has a 5mm BF it's actually a 6mm and from memory only the very first were 5mm (2004) , i 've had numerous PSTs and discussed them at length but reckon that the best ever were from the beginning of the 2nd gen 2006/7. In conclusion a modern second-hand one would be a great investment imho. Brian
  12. So many variables , I guess it’s ultimately personal choice ... (which scope , bf size) My vote on a budget would be for the Hype Zoom but if you can stretch to the Pentax or even a Leica Zoom then great. My personal fav at the mo is a 15mm Pan which I find astonishingly good but have no idea why ? Actually Johns advice is sound , I’d opt for the Pentax at that price 👍 Brian
  13. At 11mm it would just fall into my favoured FL range (11 to 15) for solar viewing .... but then I’d be looking at the sun and not the moon .... mmmm Brian
  14. Hi Folks Can anyone please tell me if the addition of the zoom Barlow will require refocusing or is it parfocal. Thanks .... Brian
  15. Truth be told it actually does take your brain (seriously) some time to get used to this single wavelength 656.28nm ... from memory Coronado reckoned it could be up to 6months (California) so UK ... my estimate was always about 2yrs ... again no joke 🌞 Brian
  16. Lunt have released an LS130 Clever move as it's a triplet (night time if you must) and is much more manageable than the LS152 it replaces. Brian
  17. I would highly recommend you look into the air spaced etalon options as you've clearly gotten the solid ones covered , the beauty of air spaced is they merely require mounting and that's it ! ... no faffing around. In my experience (like everything) it's quality over quantity that counts so the ultimate imho was produced in the isle of man. Brian
  18. Probably best wait for a used one.
  19. Probably best wait for a used one.
  20. Welly nice indeedy but would have expected no less ? I've had a 5gt & berle for over a year unused (in anger) ? But looks like the weathers not on the up unfortunately Brian
  21. Why not put a wanted ad out for a used SM90 .... I reckon the best ones were gen 1 & USA made and used to cost a small fortune !!! but they do exhibit real finesse , so you needn’t necessarily require an SMII one , but I’d also recommend collecting such as you really don’t want one de-contacting while in transit. Brian
  22. Talking about LS152s I see that ones back up for grabs on Astro Buy & Sell ? My apologies Garry , I’m sure you eluded somewhere some time ago about how bright your SM 60DS image was and I’m always striving toward the ideal set up , looking out for something new and affordable to try but I do have nearing the ideal mount situation as having a pier outside does save a lot on set up times. Hows about SGL have a Solar event , that would be great for trying various weather permitting ? Brian
  23. It’s all very subjective Garry and perhaps I’ve clarified the reason why your DS SMll 60 views were so bright , the Lunt 60s offer the same set up with one internal and one external etalon , however the SMIIIs offer the superior configuration of 2 externally stacked etalons. For the ultimate “Air Spaced” HA views one can look no further than the Isle of Man Solarscope etalons ! I do respect Stephens reviews but I’ve actually been using HA scopes a little longer than he , and as always there is no substitute for trying the real thing. Brian
  24. Mark you can replicate a similar view for less than 2k (new) using a Quark , 2” 35nm and an ST152 , I know that I do ? well the odd time that the seeings up to it ? In my experience you can’t really get to the bottom of what your really after until you try a set up for yourself , you can read all you wish but they’re usually filled with reviews by Lunt newbs , I’ve owned and tried numerous Lunts since their inception in 2007 / 8 and I’m afraid that I still do not rate them , so in summary it’s best if you can try before you buy. Brian
  25. I disagree to an extent as in my experience the lower the bandwidth and etalon / s with the greater finesse have offered me the best and most interesting views (again quality over ....... ) I’ve been using a DS SM11 60 for a season now and it displays a surprisingly bright DS image the reason being is that the set up only utilises 1 ERF (on the external stack) , whilst my DS PST uses 2 ERFs and the image given the aperture is a lot darker but having said that the etalon finesse appears to be superior. Anyway to answer your question I definately do think it’s worth trying a DS. Brian
