Hi there! I’m looking forward towards purchasing a new wide FOV eyepiece from FLO (first light Optics ) and I do to know which one to pick!
i will be using it on my f/6 8” Skywatcher dob and hoping to get good views of the Orion’s nebula , (large nebulae in general) andromeda and others.
I ve heard the panaview 32mm is a good choice but I d like to know about the other options as well. I would like the budget to be around 100€
Clear skies, Kronos.

I picked up a copy of Philips' "2020 Stargazing month by month guide to the Night Sky" by Couper & Henbest at a discount & remainder store for £3 (reduced from £6.99)
It looks like a handy little book, especially for novices, and contains a sky map for each month, monthly objects of interest as well as a listing of the year's special events (conjunctions, etc) and a guide to astrophotography.
Sooo after coming back from holidays(have been gone for a month and a half) i discovered that i had forgotten to use the lens caps to protect my Panaview 32mm from dust....
turns out, its dirty.Me having no idea what a "multiple element lens eyepiece " meant , learnt the hard way. I unscrewed the bottom part of the eyepiece and 2 lenses and a tiny ring came out... not knowing in how to put them in, tried a bunch of different ways, and still the eyepiece view was still bad.(couldnt even focus on daylight objects) after messing with it for a bit 3-5 more lenses came out. Now my 100$ eyepiece is totally screwed up and i have No idea how to fix it. I m panicking so much and i have absolutely no idea what to do. I hope i ddnt screw the lens up...
if anyone thinks they can help me, i m gonna make a system in which you can tell me how to put the lenses back
So lets name the first group of parts depending on their place from left to right : A(The first lens ), B(the ring) and C( The Thrid lens) , now, these i have no idea how to place them correctly (have in mind that A Is curved , if it gives you any information)
The next 4 pieces you see are D(The thick ring), E(The big lens) F (the other ring) and G(the final lens)
Here is a picture of each piece from both up side and bottom side
First will be up and second would be down
If anyone could give me instructions to as how i can put everything back together , i would be greatful
(Uploading pictures in a bit)
Hey Everyone. I believe almost everyone of us would be aware about the Bootes Void. If not then I'll explain. Bootes Void is a point in universe of massive volume and almost completely empty space. It's about 750 million light years from us and stretches for about a billion of light years. It definitely is huge but is also just that empty because such large space only contains about sixty galaxies.
Now what's special about this place is that it is more mysterious than black holes, even more than primordial black holes. So there definitely are many possibilities and hypothesis, like expansion caused by alien species or merger of two voids. But I've a different speculation, based on my hypothesis, this void is probably the center of expansion of our universe. What if big bang actually took place there?!!! It probably may have....
What makes me think so is that the void is not empty at all, it probably is full of more dark matter in many parts of the universe and also a centre of Dark energy in universe which makes it expand like that.
I guess almost everyone of us would be knowing of comparison of our universe' expansion with inflation (not the inflation in the beginning of expansion of our universe) of a balloon, then, yes it's true that if we mark any point on the balloon then it would look like it's expanding in every direction and the same is happening with our universe, wherever we observe, we find anything around it to going away from themselves, but we also know that a balloon has the centre of expansion from which we blows in it, similarly universe is also supposed to have an actual point of expansion and it probably is the bootes void!
It is or not?
