  1. Thanks everyone for your suggestions. I guess I now have a solution.
  2. Robin, Thanks so much for your suggestion. I do have a 1.25-2" adapter with threads for a filter. That would indeed work for most of my EPs. However both my 1.25" 18.2mm and 7mm Televu Delites and my 1.25" Televu 2X Barlow extend out of the bottom of my adapter prohibiting the attachment of a filter to the adapter. I suppose a solution here would be to screw in a 2" extension barrel onto the bottom of my adapter and then add the filter to the bottom of the extension barrel. Plenty of room in my diagonal to accommodate the extension. What do you think of this as a solution?
  3. I have an Orion UBlock, a Lumicron Olll, and a Baader Neodymium filter, all 1.25.” The Baader screws on nicely to all my Televue Plossyl and Delite EPs. However, while, both the Orion and the Lumicron fit well to my 32 and 15mm Plossyl, neither screws on tightly to my 25mm Plossyl or my 18.2 or 7mm Delite). All fit nicely to my 2X TeleVu Barlow. From several discussions on Cloudy Nights, it is apparent that that the issue of filter-fit mismatch is common. My main telescope is a Sky Watcher Pro ED100 AP refractor which accommodates my 1.25” EPS via a 1.25 / 2” adapter. My goal, then, is to make all my EP’s compatible with these filter types as well as to make the changing of filters more efficient. I could sell off my Olll and UBlock filters and buy the comparable Baader filters and assuming they fit all my EP, live with the inefficiency of changing filters in the dark. Or, I could acquire a 2” barrel extension to my 1.25/2” adapter and purchase 2” filters that would screw into the bottom of the extension barrel. I could then easily switch back and forth between my 1.25” EPs. In fact, extension barrels are cheap, so that I could even buy three of them, one each 2” filter. Does this solution make sense? Are there more reasonable solutions?
  4. I have just purchased an Orion ultrablock filter to enhance my views of nebulae. However, while the filter screws on nicely to my Plossyl EPs, it fits very loosely on the ends of my Delite EPs to the point that I do not trust using it. Anyone else notice this problem?
  5. Thanks for your comment. So you think the 7mm Delite a better choice than the 5mm Delite for Jupiter watching?
  6. Astro Colleagues, Has anyone had the opportunity to compare the TV Nagler 6 5mm to the Delite 5mm for Jupiter viewing? Just wondering which would perform better with my Sky Watcher Pro ED100. Used the Nagler 5mm with a Baader Neodymium filter last night for some pretty good views of Jupiter. However did experience some distraction by those floaters that are common among my fellow seniors.

  7. I thought parallax, but was looking for the actual report. Thanks, Reggie for that trappist-1 info site which cites the Hipparcos data.
  8. As we all know, seven earth-like planets have been discovered orbiting the low-mass-star TRAPPIST-1. TRAPPIST-1 is reported to be located only 12 parsecs (39 light yrs) from us. Can anyone described how this distance was determined? Thanks.
  9. I use a Telrad spotter on my Orion 6 inch Newtonian reflector telescope. I am considering adding a Sky Watcher ED100 APO 4 inch refractor to my viewing tools and am wondering how well a Tetrad unit would function on this telescope. Does anyone have experience using a Telrad with a SW ED100 or with another 4 inch telescope?
  10. I suppose that is possible, but I am definitely looking SW of Antares using Telrad as my guide. Thanks for the heads up.
  11. Wookie1965, great suggestion. As a fly tier, I use water repellent foam all the time so the cost to me would be even less. Of course, I will have to use grasshopper-green foam.
  12. Has anyone had any experience with the new heated dew shield for the Telrad Finder (#DN18)? Any suggestions as to a small 12V battery pack unit to power the unit? Thanks for help and suggestions.
  13. I want to thank all of you for responding with such helpful responses to my inquiry. Newbies such as me are especially appreciative of your willingness take the time to mentor our sky watching.
  14. Knightly 2112, what program did you use to generate the sky map that you included in this thread? Is in on a PC, IPad or Mac?
