Hi all, I am new to this group. I recently purchased a Orion ST80 and am interested in find eyepieces that will work well with this scope and that help reduce...
... Hmm tough one Patrick. My suggestion is a nice 32mm eyepiece then avoid pointing the scope at anything too bright ;) The eyepiece really can't reduce...
... and that help reduce chromatic aberration. ... As other have said, the 80/f5 scopes are versatile wide field scopes. High power on planets and the Moon are...
Hi Whitney, Thanks for the links, I would love one of those scopes, but it can't happen right now. I intend to try out those Burgess/TMB Planetaries you...
Hi: No eyepiece will reduce this (or any) telescope's chromatic abberation. That said, I don't find the 80 that bad in that regard. What can help is a minus...
Hi Phil, Thanks for the info. Right now I observe with two scopes. The Orion ST80, and the Orion 4.5" EQ StarBlast. I do use this scope to view the planets...
Hi Leo, Thank you for the response. I have never tried a minus violet filter. Does the color look natural on the Moon when using one? The only filter I have...
Hi Rod, Thanks for the response. What is the effect when using a minus violet filter? Clear Skies, Patrick ... abberation. That said, I don't find the 80 that...
... Hi Patrick, My ST80 is my favorite of my refractors, and the definitely the *most* used because it's so darn handy to just grab and go. I find that the...
I'll second the expanses. I use 'em with all my grab 'n go scopes: the ST80, ETX125, and StarBlast. Not perfect, but a good value, and leaving one in a hotel...
Hi Mary, Thank you for the response. I too have the Expanse series and enjoy using them with this scope. I also have Orion Highlight Plossls, but it seems that...
Hi Rod, Ok, so the filter blocks out at least one range of color. Does that cause any loss in detail? I have noticed that the 6mm and 9mm Expanses have built...
Not too much. Most of the detail that's gonna be lost is lost to chromatic aberration itself. A lot of what you notice depends on you. Usually higher...
... Patrick, Sounds like you are doing right fine with the little scope! Just train your brain to ignore the fringes and you will be golden ;) ... Well I would...
I am thinking about purchasing the Expanse 20mm to fill in the gap between my Nexstar 15mm and Nexstar 32mm. I use these eyepieces for afocal video and would...
... Jim, I don't have either of these eyepieces on hand but I have examined both in the past. Both eyepieces have removable rubber eye guards. The concern that...
Hi Phil, Thanks for the response and the info on the Expanse eyepieces. That does make sense. I really do enjoy using this scope whenever it is clear or...
... and would appreciate any information about them. > Patrick ... Hi Patrick, A lot of good avice here from everyone. Eyepiece preferences can be very...
Hi all, Has anyone here done a side-by-side comparison between the older Orion ST-80's, and the newer ones with the "fully multi-coated optics."? If so,...
Hi: The only differences I've noted have been between the "real" ST80s, the Synta made scopes, and the cheap plastic focuser equipped knockoffs. Peace, Rod...
I have the ST80-A from Orion.It came w/ the tube rings, 8x40 finder, and 90 degree diagonal. It has the fully-muli-coated objective. I don't have an older one...
Hi Mary, Thank you for the info on the Epics. I think that I will give them a try. The 3.7mm sounds right for the Moon. I have only observed two comets in my...
... to "train my brain" as you suggested. It has been awhile since I looked through my Sirius Minus Violet filter. I traded my Orion ST-80 to my wife since it...
Hi Everyone, Another question here, does anyone have any ideas to improve the contrast of the ST80? Any ideas other than blackening objective lense edges or...
... lense edges or tube interior? > Patrick ... Hi Patrick, Get as good a mirror diagonal that your budget allows. I got our first ST80 in 1997--for my then 15...
... Blackening the objective edges is a typical modification and its pretty easy and inexpensive. I often question how useful it really is but even if the...
Hi Mary, Thank you for the good information and the link that you sent. Hale- Bopp was the first and bightest comet that I ever saw. I viewed it with a...
Hi Phil, I agree with you about the eyepiece being connected to improving contrast. I recently took apart my 6mm Expanse and blackened the edges of the frosted...
