... The Jr. Gearhead isn't a bad choice for an alt-az mount, but if you plan to use one, I recommend mounting your scope with the the attitude axis... notice I...
Jim, I'm Larry. I followed up Whitney's comment recommending a Jr. Gearhead with my inherited bit of wisdom about turning the Jr. Gearhead attitude axis 90...
Hi Larry - I realized that was your post after I had already replied to it. I ordered a Microstar Deluxe (used) for my 3021 tripod and was wondering what to do...
It seems that when I bought my Skywatcher 80st, I had received the "terrestrial" OTA and not the "astronomical" OTA. The "terrestrial" OTA being the one that...
Hey there. I replaced the stock focuser with a two speed crayford manufactured by Antares. Definitely an improvement. Easy to install. I will try to upload...
Very slight vignetting (and I mean SLIGHT) using my Orion Q70 2" eyepieces (26mm, 32mm and 38mm). I really prefer to use my 1.25" Radians, which have a 60...
I'd like to replace my Orion Short Tube 80 1.25" visual back, which has a set screw, with a 1.25" back with compression ring. I know Mercury Systems and...
Hi David, Yes, I knew from looking at the scopestuff website that backs were from Mercury Systems. I was hoping someone knew of another source. Mike...
One of my first asteroid observations was made with my Orion Shorttube 80. The nice wide field of view allowed me to follow the asteroid over several nights...
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...
