I am selling my ES 34mm 68* 2" as it has too big exit pupil for my telescope. Optics are pristine and there is not even little mark on the barrel.
The price in total, 140 127 GBP, includes shipping within the EU and PP fees. Thanks for looking!
I'm looking to get a reasonably portable astrophotography set-up, using a 60-100mm refractor, with a suitable goto mount. I spotted the Explore Scientifice exos2-gt with pmc-eight goto system, which looks like quite an elegant solution, and wondered if anybody in the forum owns this mount, and what they think of it's performance & usability?
Hi guys, this is my first post and i apologise in advance if this topic has been discussed before. I am having some issues with my explore scientific iexos 100 mount, i cannot seem to get it to line up with whatever star or other object i am looking for. For example I sent it to look at the moon last night, being December 29th, when it had finished slewing to what the mount thought was the correct coordinates for the moon, the mount was facing far away from it, so i tried to do 3 star alignment and every star i sent it to, it was facing nowhere near where it was meant to be facing. Does anybody use this mount or has used it before, could you please help me out with this issue please.
Bit of a backround: I've been a keen stargazer when in my teenage years, then couldn't pursuit my passion, but recently, in my forties, it hit me again, as I moved and life is good (South facing large garden, obstructed only from the North by our house, but then I just move the scope further and viola!). Started with 90mm refractor, but was always thinking of reflector.
Long story short, I've got my SkyWatcher Star Discovery 150P GOTO a week ago. Bought it second hand, very good condition, and good mirror. Have got two nights stargazing, cought cold and I AM LOVING IT.
Now I would like to get me a nice wide angle ep for DSO spotting.
The scope is 150mm / 750mm f5. I've done some reading obviously, and Explore Scientific 82 degree series have all good reviews and fit within my budget. I can afford only one, and apparently the best for DSOs is the one that gives 2mm exit pupil. Now, for my scope that would be 10mm piece, and that is not within ES 82 degree range, so it's down to 11mm (2.2mm exit pupil) or 8.8mm (1.76mm exit pupil).
My question is: which one would be better for my rediscovered passion? I'm gonna be using that ep for faint mostly.
Thanks to everyone in advance for any kind advise.
Heyyy its meee kronos and i have been wondering about getting a filter...I really want the best contrast and brightness i can on my nebulas(i want to view M42 M57 M27 M31 M81 M82 and lots more) with my future 8" dob. Is this filter really going to help me?
If it just a matter of quality of the filter itself can you suggest a better one in the same price range?
Or will not the uhc filter help me in general .IF so can you reccomend another one?
