Observing Report/Scope Rec... Used ETX 90 (OTA only) VS New ES Firstlight 114?
So I had my best observing session with the TS-80. I paused shopping scopes to look through the one I have. Best seeing so far. Unquestionably recognizable bands on Jupiter, good view of Orion Nebula, good moon views. All viewable with a 3X Barlow and a Zoom ep set to 7mm. All very clear compared to all other sessions I've had and all despite street and porch lights all around. I would have gone after Saturn if trees/buildings weren't obstructing. Even a tripple star group in the Orion Nebula could be picked out. It looks like 1 star to me otherwise. It really helped me appreciate how much seeing affects observations and appreciate that such a basic scope can give decent views within its limits, given the chance.
Bigger scopes have more light to work with so should be less affected by a given set of seeing conditions, correct?
My telescope shopping has brought me to these two options...
Which is a better deal? A used ETX 90 OTA at $80 (I have a heavy duty 2nd hand photo tripod already for my TS80? Or a new Explore Scientific Firstlight 114 at $100?
The ES states it has a parabolic mirror. It comes on an Alt-AZ mount. The aperture and that mirror are the draw for me as well as its price. I've been looking at the F/8 Powerseeker and some 76mm reflectors and only the Orion Space Probe 3 is cheaper at about $70. The ES's bulk is a negative for me. Is the mount/tripod stable with it?
The ETX 90 is tempting because it's so compact. I'm spoiled by the compactness of my TS80 because I can just throw it in the backpack it came in with its accessories (sans tripod) and throw the admittedly large tripod in the car with it. Same for taking it out back, the tripod is by far the more labor intensive part of the setup but it's so stable. The ETX is a slow scope so finding stuff may be a challenge but I guess a RACI could greatly help. I've heard there are wide angle eyepieces that also may help. Any decent budget (<$50) ones out there if I get this scope?
Thanks
