I now too have a Radian Triad filter and I want to try to use my rasa 11" and qhy600 on the Rosette Nebula to the left of Orion and want to obtain the blue on the inside and orange on the outside-look. Also ps: I do have a lifetime subscription to PixInsight now...and am new to that but have a little experience with photoshop. So if anyone can do TeamViewer with me for PI that'd be neat or know of a Christian person who can that'd be neat...also I know we're basically off by 12 hours...so as long as we agree to figure that out...thanks for all you guys help. What do you think about a 12 arcsecond offset PA on my cem120ec2? is that good enough for the 620mm fl of my rasa? however I might include a 8" edge hd sct later once I buy it and RedCat...and know the edge would push the fl and slowness of optics and would be better for 'small' things in the sky through my qhy178 (which I already have that camera too) plan to piggy back all 3 or 4 of these scopes...don't worry the mount is such a behemouth that I think it can hopefully handle it...ps my email is
davewilliamstar@live.com and phone number (269)625-3560 I'm from the states from northern Indiana so if you have a way of calling long distance...God bless take care clear skies. David
