I had been reading up on the Explore Scientific 16" truss dob, with the most recent questions in https://www.cloudyni...d/#entry9678584
Last Monday I decided to dive in, added the scope to my cart on the ES site, then cancelled and thought I should try Astronomics first after I deposited a check in the bank. When I got home the price of the scope was $800 higher! I called Astronomics and they said a new price list had come out from ES, I called ES and explained that I had meant to buy one that day after depositing a check. The ES folks let me use the old price ($2400 vs $3200 USD) so I checked out.
Scope arrived yesterday. Box looked very roughed up by FedEx, torn and scratched and dented in several places. Thankfully the whole thing had been packed in a second outer box, and inside it the two large pieces were in their own boxes and styrofoam. ES had done a great job packing, and no pieces were damaged.
Weirdly, the manual that had been packed inside was for ES refractors. Called ES, they emailed me the right one and said they would mail a hard copy as well. I used the youtube video to get it together, and I agree with the comments of other users. For the money the workmanship and part quality seems good. The finder is garbage, and the hockey puck brakes don't seem to do anything. I had got the extra weight so no issues balancing at different altitude.
I couldn't get the shroud to fit properly, so called ES again and they sent me a return postage label to send it back. They said that the way I described the shroud sounded like the original version, not the updated one. Despite the small issues noted above, I think the scope looks great. Just waiting for the clouds to go away now.
So I have a few questions for you big dob / truss dob users :
1. The primary rests in the bottom of the box, and ES suggested keeping the tissue paper that covered it in shipment as a permanent cover during storage. I worry about scratching the mirror, is there some other way to keep it safe in storage and transit? Or do you guys leave the primary uncovered (but enclosed) in the box?
2. I have a 17mm Baader Hyperion, a couple of 2x barlows, some 1.25" Plossls (10mm, 26mm), and an Orion Q70 32mm 2" eyepiece. For filters I have the set of Orion 1.25" planetary filters (orange, blue, etc), an Orion 1.25" Ultrablock filter, and an Orion 2" UV/IR cutoff filter (I used for DSLR photography). With the shroud return I will have a credit at ES and they also carry filters and eyepieces. With a 16" scope, would a Hydrogen Beta filter be better, or an OIII filter, or maybe a different eyepiece. My primary usage for the scope will be hunting the Herschel 400, Caldwell Catalogue, and Globulars.How can I best supplement my above accessories in a way that most improves my viewing of these targets with a 16" scope?
(I will have a shroud so that is not needed, and I hope to replace the finder with an old 9x50 RA finder I already own).
Thanks so much for the input and help!
