100ED frac

[nightfisher]

On the back of my other recent thread (tempted to call it a day) the decision to downsize to just one scope has been made and i have some one coming this morning to take a look at the 150 Mak, and after a PM exchange with a valued friend on here last night, has me looking at the 100ED as my only scope, yes i am still strongly considering the 120ED, but as pointed out last night, to have just one scope and for it to sit dormant for 345 days a year maybe the 100 will be the better choice, i dont need huge aperture for DSO`s as i only view a small handful, my main use is for Luna imaging

So how good is the 100ED?

Aperture is not just relevant for deepsky Jules, it gets you resolution too.

The 100ED is a lovely scope, but ultimately will just be a better corrected version of the TAL say. The 120ED gives you the same focal length, so the same image scale as the 100ED but with greater resolution so your lunar imaging will be better and planetary views nicer.

Jules. One reason I keep banging on about this is that you keep going round in circles with different scopes, successfully avoiding the one which hopefully fits the brief.

This can't be about money, as you have the necessary funds tied up in other scopes currently. I would bet that the 120ED would give views that rival the 150 without the cool down. The 100ED won't do that.

Why don't you try Shane's? I'm sure he would let you have a look through it to make sure?

Hello Jules,

I  bought a Celestron 100ED to use as a holiday scope in France - It had the same optics as the Skywatcher 100ED.

I compared it to my Takahashi TSA102 triplet.

The 100ED was slightly dimmer and not quite as sharp on the planets and did not quite have the contrast the Tak did.

But for the price I was VERY impressed with the 100ED.

The 120ED would be a better all-rounder in my opinion though - giving more brightness and resolution on the moon and planets to see smaller details.

Julian, I have found my C100ED, quite a versatile scope. With a long focal length with excellent correction. No Chromatic Aberration. It makes a nice planetary scope, splitting double stars, a nice visual scope and also coupled with a reducer, a nice imaging scope. A lens with a high strehl value.

The image below of M13 was taken with my C100ED with a skywatcher 0.85x reducer with a DSLR. If only Celestron would have made a same colour job 120ED to complete the family.

Stu, you are of course right to bang on about the 120, and i am just exhausting options, as we speak a 120ED is top of the list and makes perfect sense just the issue of shelling out £600 ish to have it sit and gather dust for most of the year, you are right my other kit will cover the eventual outlay and now i have had time to think about it the 120 might just have the practical edge over the mak, problem is i have seen a 100ED that could be mine for a stupidly cheap price

It would be very tempting to take a look through Shanes, he did offer to loan it for a while but by time i have driven over, i could be holding onto it for a good while with out getting chance to observe with it to then have to drive over again, also if any thing happened to it i would be hard pressed to replace it for him as they donr come up to often

Well you are certainly exhausting me too Jules  

As I said, this is not about money. You are spending loads on drones so you can afford it, especially by selling your other kit.

The point is that if you want a scope that is not going to disappoint, then it has to be the right scope. You love the 150 Mak when you have time to use it. If you buy a 100ED then I guarantee you that at some stage you will be back on here saying that you miss the resolution of the Mak and wish you had not sold it.

This is all dead money at the moment anyway, so carry on treating it like that. If you are carrying on in astronomy, give yourself the gear you need to do it properly then stop thinking about it as money and just be glad you have it there for when you want to image or observe.

[nightfisher]

I dont want to go into any detail about it but i might buy the 100ED for resale purpose as i can see over £100 clear profit in it like i said a true bargain

I recently down sized from a 150 reflector to a 100ed and don't regret it for a minute,

yes a very slight drop in resolution, but I mean very slight. I am sure the 120ed as others say would be better but at a lot more money for 18mm of aperture.

I wander all over the sky when observing on a manual mount and I really do not regret the downsize for a minute.

Lunar observing is one of my passions and the 100 works very well for that.

Jules, the 100ED is a truly fine refractor which could provide a lifetime of trouble free enjoyment. I've owned a 100ED and loved it, but I've had three 120 EDs and they are far better! The SW 120ED  Pro is a lightweight powerhouse and if you had one you'd need to look no further. 

Mike ☺

I love these threads. For entertainment value, I only wish we could publish the sound effects produced by our brains.

Whatever would we do if Jules ever acquired a 120ED? Bless.

Told you not to get rid of the Mak180 ...

Its more than likely that i will get the 120ED, i might just get the 100ED as a stop gap investment

The 180 was a lovely scope but i could not go back to one of those, i would be lucky to use it one night a year

We would rest easy in the knowledge that the ying and yang of the astro world were at last in balance

Gonna put my neck on the line here, I will get an ED120, but as said i might get the 100ED as a stop over and profit maker, this could put £100 into the 120 pot and i might get to use it a few times

Sounds like a no brainer. Good catch if you can get a ED100 for a great price and then make profit on it later on. I just got a Celestron Omni 120mm XLT for a great price. After a little TLC it came up like new, with the lens especially. If I were to ever sell it I would make a small profit on it for sure, but not something I am contemplating at the moment. 

[nightfisher]

sob sob I no longer have a Mak 150 pro, it has left home to live in south Yorkshire, but has gone to a kind new owner, end of an era as i have owned Maks for a long time, but one step closer to a 120

[iPeace]

If things go as they surely must, you'll have a complete set of 80ED, 100ED and 120ED from which to make your final selection.

Larks!

No this wont happen as the ED80 is next to get listed for sale, if i get the 100 then when a 120 comes up this will go for sale, another good reason for the 100 is investing my pennies to stop me buying more flying machines 

[Highburymark]

The 100 is no slouch though - I love my Equinox 80 but have often thought what an excellent package the 100ED pro offers with its extra 400mm focal length.

Looks like the 100ED wont be happening now since its where abouts has been posted in the astro lounge (not by me) more people will be tempted to bid now and it will go for a higher price

To be fair Jules, it was on eBay and most of us have searches set up to highlight these things anyway. I don't think the post makes any difference, it was always in the public domain.

Yep, it is listed on a public auction site, i was just hoping for that rare thing, a real bargain, but at least the astro Ying and Yang will fall into equilibrium as i will just have to keep looking for a 120

Maybe the 100ed was not to be . And could be a blessing in disguise. As i think you really wanted a 120ed all along. The 120ed is the scope to go for if it's only one scope you will be having. And now fate has intervened. Go for the 120ed and have done with it IMO☺

Just keep thinking Sharper Star Images and Faster Cool Down!

Whichever size ED you end up with, you'll have a top class, rapid set-up scope that can be used to advantage for those 20 minute sessions through gaps in the clouds.
