  2. Solar Max Coronado 70mm Scope

    Sorry just read Shanes post again with my eyes open this time . So it's NOT 70mm at all then!!!
  3. Solar Max Coronado 70mm Scope

    Is it at all possible they have done it in a similar way to a PST mod using internal erf a 1/3 way down the ota. Why have a front double stack with the expense when you could fit an internal ? I assume you get the same desired effect? Of the top of my head I'm sure lunt do a similar thing with their 80mm don't they??
  4. Berlebach spreader stopper

    I've learned to take astroboot listings with a pinch of salt John. Sorry to hear the tripod didn't come with an EP tray Dave but at least they got in touch first to check if that was OK. Was it a Berlebach tripod in the end ??
  5. skymax 127 eyepieces

    BTW the aperture is restricted to 26.4mm (don't quote me on this but it isn't far off) or so on the visual back so you may experience vignetting in 2" ep's over a certain afov and focal length. There is argued to being some gain for using 2" diagonals though. This is put down to the larger mirror not suffering edge drop off like a 1.25" would. I'd like to bet you'd be hard pushed to notice any advantage though.

    In such a slow scope I doubt you would get your monies worth out of the TV tbh Jules
  7. Did you not recently have issues with your quark? Maybe this is a result of your erf combination ?? As you say thought if your happy.
  8. @DRT in my mind the fact Daystar had a configuration wizard http://www.daystarfilters.com/Wizard/ would strongly suggest to me there is an upper limit to the use of a 2" UV/IR filter before an ERF is required. If you do contact them it would be interesting to get some clarification on this.
  9. To some degree I agree but we all have an obligation to offer safe and informed advice when it comes to looking at the sun. Solar observing is dangerous and SGL is an open forum. While your KG3 may work fine it is best to point out the pros and con's of absorption filters over rejection filters as someone may not buy one that rattles in its cell and it goes pop. In the same way I questioned your point about never removing ITF filters in case moonshane had overlooked something and I was going to give him the heads up before he damaged his eyesight. I think when it comes to solar observing and if not done with respect the damage it could bring to your life, not just your eyesight, I don't always think "people can do what ever they want" is the best advice!
  10. I know its one competitor against another but Baader's site says the trouble with the kg3 filters are they can fail due to absorbing the heat and expansion where Baader UV/IR reflects the heat.
  11. I don't want to doubt you Derek but I would immediately cease using your combo until you have contacted Daystar directly.
  12. I think moonshane has removed his rusty itf and replaced it with a 2" 35nm. As said before though I'm unsure how it all works as he already has an internal 80mm d-erf which I believe have IR rejection and pass 45nm ??
  13. So from what I gather from Altair's site apertures of115mm and over you need a front mounted erf ? So you are correct DRT it's not 75mm ?
