I just bought a used XT10 and I would like to get a couple of good eyepieces that will work with this scope (4.7). I thought about a Hyperion 17. Any advice...
We have the same scope you do. The two most often used eye pieces we have are the Televue Nagler 12mm, type 4, and the 17mm, type 4. We also have the Televue...
... 10mm Pentax XW gets my vote, followed by a 10.5mm Pentax XL. If you really want a slightly lower power, closer to the 17mm, then I'd vote 14mm Pentax XW or...
Pentax XWs are great EP with 70 degree view and run around $260 used on Astomart. Bob ________________________________ From: RapidEye <RapidEye.US@...> ...
... The group was put together befoe Orion had designed the Starblasts so no thought was ever given to the issue. Try your question and judge for yourself...
Hello Group! I've only used refractors and SCTs, BUT now I'm going to start mentoring a youngster that received an Orion Starblast 4.5 reflector for Christmas....
Get yourself a collimation eyepiece and it will come with some instructions that are worth it's weight in gold!!! The first thing you will want to do though...
Thomas, Thanks for the tip! Reading the manual's methos of using the focuser cap with a hole in it, looking for the reflection of my "eyeball" overlayed...
... That narrows your choices, quite a bit. For observing with glasses on, you need eye relief - 20mm is the recommended. That really gives you 3 good series...
... The TeleVue Type 4 Naglers that Carol mentions have very generous eye relief and are quite usable with glasses on. I am another believer in the 12mm Type 4...
FYI the Ethos 13 works great on the XT10. I had TV 12mm type 4 before and Ethos measures up well. Bob ________________________________ From: Phil Lefever...
Absolutely! Both my son and I wear glasses, and I have glaucoma. Someone on the list also mentioned recently the idea of buying a cheap eye patch to cover ...
... mentoring ... Christmas. ... Hi Bob, I own an Orion 4.5 and it is a great telescope. But it is a bit finicky about being collimated properly. My first...

Hello, I'm new to the group - BUT - can provide experience to this particular issue. The Nagler Type 4s have an interesting capability. Once the EP is secured...
I've had an Orion Classic 8 for about two years, and just purchased a HOTECH laser collimator with 2 inch adaptor. I think you can do a very respectable job of...
... Bob, A slight correction, the adjustable eye guard doesn't have any effect on actual eye relief. Eye relief is the distance from the top eye lens to the ...
Phil, I did indeed get it reversed - HOWEVER - the instruction sheet DOES specifically "state" the "maximum eye relief is achieved in the barrel fully down...
... Indeed their statement is correct, in this case they are speaking of effective or usable eye relief. Of course if the eye lens is recessed into the...
... The most significant difference between the 4.5" and 6" Starblasts and the XT lineup are the F/ ratios for the same sized XT's - I'd call them fair game...
... I have a couple of thoughts on this. I struggled with collimation for quite a while until I watched the tutorial on Andy's Shot Glass page here: ...
