That the range goes red white blue ? You can call it red yellow white bluish if you prefer : )davenn said:not sure where you get that from ?

wabbit said:Yes but good ones have a flat transmission curve. See for instance http://www.alpineastro.com/Solar_Observation/Images/DERF_Curve_Lg.jpg
Try Baader they ain't baddavenn said:I haven't seen one yet that doesn't change the colour of what is being viewed
Very nice! especially the view from apogalacticonliometopum said:Dr. William Harris, and his Ph.D. student, Jeremy Webb, of McMaster University, wrote an article for Astronomy magazine, July 2014, titled "Life Inside A Globular Cluster".
cool link and nice artistic impressions thankyouliometopum said:You can see the view from different locations within a globular cluster at Jeremy Webb's page,

Three images:
1. View from the center
2. View from near the half-light radius of the cluster
3. View from apogalacticon

even if you are in remote suburbs you will be able to see the MW only for half of the year . can you see how ?wabbit said:You'd need to be in its remote suburbs though, otherwise I suspect the sky would be so bright from all the nearby stars surrounding you that you wouldn't see the milky way at all. Which would be quite a sight in its own right...
Oh it's even worse than that : you also need your star to be on the right part of its orbit around the center of the cluster lest the cluster blocks the view. Lots of geometric constraints to combine...vrmuth said:even if you are in remote suburbs you will be able to see the MW only for half of the year . can you see how ?
