Skywatcher 100 ED Pro Esprit - Great Performance

Recommended Posts

Hi Guys,

I thought I would share with you my first hand experience of the Skywatcher ED100 Pro Esprit Telescope, I have only had it a few months, but so far I am extremely happy with the results, it is so sharp and the contrast is very high.

I live in a small town, Stowmarket, Suffolk, UK, where the light pollution is not to bad, but still I have to be cautious with the direction I choose to point the telescope.   All my astrophotography is done from the back garden on my patio.

I have had a few different telescopes over the years, but I always found myself moving more and more into astrophotography, so after some research I selected the Skywatcher ED100 Pro Esprit, as many of the other users had commented on the sharpness and contrast.  As I wanted to focus on more wide field astrophotography the F5.5 speed giving 550mm seemed the right choice, I also use an ED50 Skywatcher Guide Scope with an Altair Astro ASI130mm camera for the guiding and of course PHD2 software, all mounted on my Skywatcher HEQ6 mount.

Here is a shot of the Andromeda Galaxy, 20 x 30s stills at ISO 800 on my Sony A7Rii, no filters just RAW images processed with Photoshop, Stacked Mean option.  I used the Trevor Jones video on his BackyardAstro You Tube page for processing DSO's and it seems to work very well.  What you will see from the image is just how sharp it is, something that really surprised me when I processed the images.

This has inspired me to spend more time outside in the garden to photograph more objects, plus I have recently purchased an Astronomic CLS Filter for my Sony A7Rii, so I am looking forward to using this to see if it improve the contrast.  I will keep you informed.

Also I am looking forwarded to trying my Olympus EM1 MK2 camera, yes I know it does not have the capabilities of the Sony A7Rii for light gathering, but it does have a really clever mode where it can stack the images in camera to reduce noise, so I will also let you know how this went as well.

Best Regards

Jamie

Good stuff Jamie. It's always helpful to share experiences of equipment whether positive or negative. As Daz, I am a signed up life member of the Esprit 100 club, love it and look forward to putting it back on the mount very soon! Happy snapping and clear skies.

P.S. Good to see Trevor Jones and his AstroBackyard YouTube channel getting a mention on here - I too enjoy his entertaining and informative videos.

Very nice image and post. I was very close to getting one of these myself but then a William optics flt98 came up at a cheaper price and temptation got the best of me.

Although I'm extremely happy with my flt98,  still can't help but wonder which scope would come out on top in performance for astrophotography.

Be prepared for a Canadian youff you tuber experience, with hints of sponsor driven plugging, but he has a lovely sense of humour and is very passionate about the subject. I don’t think you’ll really learn anything from him, but it is good entertainment!

I had a chance to get out in the garden last evening, had a go at capturing NGC 7023 - Iris Nebula, only managed to get 12 good shots, 240sec x 12, combined in Photoshop with Mean Stacking.  The dew was super heavy and currently I do not have any dew heaters (next purchase) so lost the battle after around 2 hours. 

One interesting point is I captured these shots with the long exposure noise reduction switched on with the Sony A7Rii, so each shot took 8 mins to take and save, but as a result the noise levels were next to zero at 800 ISO, and at the end of the day the noise is always our enemy.

I am very happy with the final shot,

thanks

Jamie

I just ordered one from FLO.....  

You will not be disappointed, it is very sharp.  Make sure you have a Bahtinov mask for focus, as it is critical with this scope, the 10:1 focuser does help.

lets see your results once you have the little beauty 🙂

I stated the name of Trevor Jones' You Tube page incorrectly, it is 'AstroBackYard', he takes a very light hearted view of the hobby and helps with the more basic things that we all having trouble with when first starting, plus the videos are quite entertaining with his dog Rudy 🙂

Sorry Nikolas, no recommendations for auto focus systems, something I do not use.   I focus between each set of frames with the bahtinov mask, lock the focus and shoot.  Once the scope is down to ambient temperature, it does not seem to change much.

Here is another shot to show just how sharp the Skywatcher 100 ED Pro Esprit Scope really is.  This is 3 x 30s Sony A7Rii Frames, stacked in Photoshop of the Hercules M13 Great Globular Cluster.  I think I have found my forever scope 🙂 

thanks

Jamie

I use the Lakeside motor focus system with SGP for autofocus and can highly recommend it.

I have the 100 and the 80 Esprits, both of them I simply love the quality and images.

The dew shield unscrews IIRC.

The standard focuser is good so order from Ian King a Lakeside Motor and controllers, dead easy to fit and works superbly.

I have the Moonlite on my 100 and the lakeside on the 80, both are now controlled by my Pegasus's control boxes which are brilliant.

If you notice your stars a little odd shaped then make sure your back focus is correct, @RayD helped me out tremendously to ensure that I got the correct back focus of 55mm which made an immense difference to my star shapes.

Yep I can't see my changing either of these scopes as they are just superb within my abilities.

Enjoy and good luck.

Certainly an impressive review , Jamie . I am kicking myself . I bought a flex tube 250 Sky-Watcher dob only 10 days ago and I’m already regretting that I didn’t go for another refractor . Don’t get me wrong , the dob is great , but it’s huge and to be honest I was swayed by the large aperture. In reality I want to get into astrophotography and I should have bought either the model you have or even the 80 mm version . My wife’s gonna kill me when she knows i want to change lol. A great image too , of the Andromeda galaxy . 

Clear skies .

Anybody can confirm that the backfocus distance using the dedicated flatterer is 63mm or 55mm (i  am using as camera the Atik 383L) ?

I am a little confused..

If you are using the m48 adapter on the back of the flattener, then it's 55m. Without, it's 63mm.

Sorry guys, quick question. I've read previously that the 100 is the only Esprit size which doesn't have provision for mounting a 2" filter inside the adapter/FF. Is that correct?

and also, i can see that the size of the box that the newer Esprit 100 comes in is significantly smaller than the older version. Is that correct?

Older version Esprit Box:

      Hey guys!i need to make this quick! I want to get a new 6mm eyepiece.I have a 8" f6 dob and i want to get a nice 200 mag and put the telescope to its limits at 400x
      The most i ve seen with is 240x for Jupiter and Saturn .i ve heard they looked stunning at 400x and i am keen on trying it.Ive got my eyes on a 6mm Skywatcher UWA eyepiece.and i have a Bst Starguider 2z Barlow lens.And i seem to be having problems with my 8mm Bst Starguider (300x in total).the bst has a 16mm eye relief and a 21mm lens diameter,but when i barlowed it and look at the moon yesterday,it was hard finding the right spot to look through the eyepiece and when i moved the image disappeared.I dont know if it will have that effect on planets,when I looked at mars it was fine but i definitely want to avoid that from happening again.Will it happen?
      The Skywatcher eyepiece i want to buy has a 16mm eye relief too.I dont want to make the same mistake now , i want a 6mm eyepiece at the price range of 50-70 euro either from flo or amazonuk.If the Skywatcher will have similar results,can you suggest another one?

      I bought this second hand, but it was almost untouched, and a relative bargain to boot.  New it costs 1199 EUR from TS (approx. £1035 as of 08/03/2019 but who has any idea how this might fluctuate).
       
      Highlights:
      Apo air-spaced triplet with FPL53 Multiple focus positions thanks to removable tube segments 2.5” rack and pinion focuser, rotatable, dual speed controls, 6kg payload, with printed scale CNC tube rings and dovetail supplied Retractable dew shield  
      First impressions:
      It’s a really nice box.  Whilst it’s described as a ‘transport case’ the supplied storage box is sturdy and well made.  Inside, the foam fit is precise bordering on tight.  It’s actually mildly difficult to get the scope out of the box.  Things get a little easier if you loosen the tube rights slightly, allowing for some tube rotation, and a longer term fix will be some straps to aid lifting the scope out vertically.
      The scope itself feels very well made, and is what I’m choosing to refer to as ‘reassuringly weighty’.  At just over 4kg (without diagonal, eyepiece, or finder) there are definitely lighter options available, but it’s hardly a heavyweight.  The finish is powered coat white, which looks and feels very nice.
      The focuser is very smooth (compared to my SW ED80) and feels pleasingly solid.  I’m not going to be testing the stated 6kg payload any time soon, but I can easily believe it will be able to handle it.
      The dew shield is held in  position with a single thumbscrew, and whilst it’s retractable credentials are clearly warranted, it only seems to extend a couple of centimetres.  As it happens, this takes the overall length down to 450mm which was the very top end of my acceptable range in order to meet my ‘travel’ requirement.  The focuser body also incorporates a finder shoe, but if you wanna  finder then you have to supply your own as there’s nothing included.
      The idea of having additional tube segments is that you don’t have to rack out the focuser so far, and so improves stability.  This also allows for multiple reducer/flattener options for imaging use.  The TS website details the specific configurations using their recommended equipment which provide a faster f/4.9 option for sensors up to 36mm, or a full frame flat image at the standard f/6.6.  I might be exploring these options later, but for now, this is going to be for visual use.
       
      First light:
      OK - this barely counts, but I was impatient.  Predictably enough, first evening with a new telescope and it’s raining.  But I did manage a pretty decent look at my neighbours TV aerial and chimney stack.  They need some re-pointing.

      The following evening (9th March 2019) was less rainy, but much the same for cloud, all but for about 30 minutes of relatively clear sky, interrupted regularly by patchy cloud.  So still not great.  However, my ambitious setup to allow for cooling paid off and I did manage a few minutes of actual use with a SW 28mm eyepiece.  The Baader Zoom I also treated myself to for my travel use is frustratingly still not dispatched.  And when I say set-up, I mean just carrying everything outside.  I’m using this on the SW AZ-Gti mount, and a Manfrotto tripod I had already, so it’s very easy to pick up and take outside.
      I was using the scope with one of the two removable sections in place (this is how it is stored in the supplied case) and was able to achieve focus with a 2" diagonal without having to rack out excessively.
      Sirius was an obvious target to the south, and an easy hit.  Brilliantly bright, as expected, and a blue-ish white colour.   The upper half (the rest was below my sightline from home) of Canis Major was easy to see, with several of the background stars also visible.  Despite the less than great seeing, the view was impressive.  Stars were tight and there was no obvious chromatic aberration.   Moving up to Betelgeuse, it’s orange-red brilliance was very pleasing, and again I was able to make out some of the fainter surrounding stars.
      Overall the view was very impressive, and bright.  My only real comparison is with my SW80, and of course I now have over 25% more light, so that’s to be expected.  But still, it makes an obvious difference.  I wasn’t able to note any CA or distortion, and a quick full visible spectrum (no filters) star test reflected spot on collimation and no apparent astigmatism.
      Alas, the break in the patchy clouds did not last long, and I was soon packing up for the night and heading out for a beer.  I’m looking forward to getting some more quality time with this kit, and who knows, I might even align the AZ-Gti next time and write a brief review for that too.

      The Horsehead Nebula in Orion. This is one of the first deep space objects I saw in a book as a child and it captured my imagination - I’ve been intrigued by this incredible Universe ever since. As a small child, I’d have been blown away to think that 40 years later, I’d capture this image from my own backyard. I've only been astroimaging for less than a year so would appreciate any constructive comments/ criticism.  Higher resolution version at: https://astrob.in/393553/0/
      I tried something different with this image  as I was severely restricted by time and conditions - battling last months full moon and a small cloud free window of about two hours each evening where the Horsehead appeared between some large trees and the edge of our house!
      I took mainly Ha because of the moonlight but then blended in some Lum and Blue data to one master image. This brought out more detail in some of the nebulosity.  The resulting Master was then processed through the red channel only in PixInsight and Photoshop:
      Ha 36 x 240s
      Lum 25 x 60s
      Blue 20 x 60s
      Scope: Altair 130ED Triplet
      Mount: Celestron CGX

      Hello,
      I own a Vixen ED-80 refractor which is used with a custom focuser by Telescope Service.
      (pictured below)
      A Celestron f/6 SCT reducer corrector did not provide decent images either because it is not appropriate or because I did not maintain the correct distance. 
      I am thinking of buying the Sky-Watcher .85x Reducer/Flattener instead, as it is made for similar ED80 telescopes. 
      I do not know what is the correct distance of the SkyWatcher reducer for my setup and more important, I do not know if it will focus with the custom TS focuser.
      Do you have any similar setup that you have used successfully?
      Clear Skies!
      Paul
