Hello all, I was recently gifted an LH50THa solar telescope from a friend. It didn't come with a manual and I'm unsure if I'm missing pieces. I have experience with night time telescopes, as you can see I included a photo of my Orion 130St Reflector that came with an equatorial mount. I contacted Lunt (who were VERY helpful) who suggested purchasing a dovetail to use to mount my solar telescope to my nighttime telescope's mount. I felt bad pestering them with further questions, and I'm sure there are several ways to do what I'm asking, so that's why I joined this discussion forum. My question is, once I purchase this dovetail accessory (if someone could suggest specifically WHICH dovetail I need, that would be super helpful) how do I attach it to my equatorial mount? Which pieces do I dissassemble and then how do I reassemble it for solar viewing? Links to a site where I can purchase this dovetail accessory would be greatly appreciated. Question 2: It comes with a 20mm eyepiece. Would a different eyepiece help me get better views of the sun? Since it was a gift I'd be more than happy to splurge on some extra goodies. Any and all suggestions are welcome. Thanks! Jim 20160726_161913.jpg.crdownload 20160726_161938.jpg.crdownload
I was doing some solar observing and was puzzled by the haze i was getting in the eyepiece especially as my white light scope was showing clear. After some checking found that the entry lens on my B600 blocking filter has something on it, see picture. Tried cleaning it off with an optical cloth but it remains. Has anyone got any ideas what is the problem and what to do about it, is it something that I can do myself or will it require sending to Lunt for fixing.
Just ordered a Lunt LS50THa scope from FLO I had been undecided about going for the 50 or the 60 but in the end decided the 50 was the better buy. I mean yes I would have liked the 60 with PT and Feather Touch but my wallet said otherwise. Have also ordered the Feather Touch focuser, Sol-Searcher and a short dovetail bar. Still works out hundreds less than the cheapest 60 but has the pressure tuning and Feather Touch that I wanted and can be double stacked in the future if I want to. Got my old Manfrotto 475 tripod with modified 405 geared head down from the loft and dusted off. A bit overkill for such a small scope perhaps but you can't have too stable a mount. Have used a C8 on this mount so it won't even notice the Lunt. Will still be light enough to carry the full set-up outside one handed though. I appologise in advance for the cloudy and rainy weather to come in the next couple of weeks. John
I have been asked a few questions and seen a few discussions online regarding the double stack (LS50c) for the Lunt50THa. So I thought it might be interesting to post a couple of images without and with the Double stack. Both these "RAW" images are 2 pane mosaics taken with my DMK21au618 with no sharpening at all, as I didn't want to influence the comparison. Both are also stacked in Reg6 and combined ICE. Double-stacking reduces the bandwidth from <0.7 to <0.5 Angstroms. I am no Solar imaging expert and more skilled imagers would maybe get more out of both set ups, but the difference is clear to me. Whether it says more about the single stack than the double I will others to decide Just to add the conditions were far from suitable to be honest, with high haze around all the time and the seeing pretty average as well. This accounts for a loss of contrast in both images, but I guess its still a valid comparison. As for the cost? Obviously a very personal thing, for me it transforms the Lunt50THa and I am delighted with its performance.
