  1. 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
  2. Hi, this is my first time using my new Esprit 100ED, my first time processing using Pixinsight, and it's my first image using a Mono + filters. I loved them, can't wait to try on more targets. here's the result: Equipments: SkyWatcher Esprit 100ED SkyWatcher EQ6-R SkyWatcher EvoGuide 50ED Guidescope Imaging cam ZWO ASI1600MM Cool Pro ZWO EFW ZWO LRGB+NB 36mm filters Guiding cam ZWO ASI290MM Mini Seeing was avarage Location was in a Green Zone Exposures: Ha 11x1800sec L 39x300sec R 13x300sec G 15x300sec B 15x300sec Darks: 24x300sec 10x1800sec Bias: 70 Thanks
  3. How good is this scope for rich/ flat field and reducing FC & CA? Much cheaper than Tele Vue equivalent.
  4. Hi Guys/Girls 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 need to try a real pro level 'cooled' astro camera just to see how much better it could be, as the Sony A7Rii is just stellar ! I am very happy with the final shot, taken with my Skywatcher 100 ED Pro Esprit Scope on my NEQ6 mount, Skywatcher ED50 Guide Scope and Altair Astro ASI130mm camera, PHD2 of course. The sky was nice and clear with low light pollution, as around 5 miles from major town. I do not take darks or flats or use Deep Sky Stacker, and I do not use filters, plus the camera has not been modified, so I am always delighted with the results I get from my set-up, as I have a deep level of respect for the hard work that most Astrophotographers go through to get the incredible images that we see here in Stargazers. I have read that some people believe that the Sony Alpha cameras have a tendency to 'eat the stars' and not show everything captured, to be honest, I always used a Canon 60Da for many years for my astrophotography, until one day I though, what if my Sony A7Rii could be used, the first time I did this I released that it was time to sell the Canon 60Da, the 'Remote' (free) Sony software is almost as good as BackYardEOS, but the cameras are a decade apart in performance, the noise levels on the Sony are at least 4 maybe even 5 stops better than the Canon, that is the Sony A7Rii at 3200 iso equal to the Canon 60Da at 200 iso, so at 800 iso it is just so impressive. As you can see from the picture only 12 frames, stacked in Photoshop (Mean). Open to comments and welcome a discussion/debate, thanks Jamie
  5. Hi all, Any help and advice you can provide me on this subject would be greatly appreciated. I'm not new to Astronomy but very new to Astrophotography and currently in the process of researching the equipment to start capturing photo's using my skills of being able to find already, Currently I have a Skywatcher EvoStar 80ED and looking at upgrading to the Esprit 80 more personal preference but I am unsure if my Current EQ1 would do the Job for this I've been searching around but can't find too much info. I've looked at the Weighs of the Esprit and if I've looked correctly I think my EQ1 would struggle to support the weigh. Kind regards Sharkey
  6. Those good people at FLO have kindly sent me my new baby... an Esprit 100ED! OK, I had to swap it for some of the 'money' stuff but it was certainly worth it!! Just need the custom CCD adapter and some clear skies and then we're good to go! Here's a couple of pics - there'll be more when it's installed in the obsy!
  7. After a bit of a false start, I finally got a real first-light test image on 7th April, with my new Esprit - the false start was one of those annoying 1D 10 T errors!!! Anyway, 21 subs managed before the clouds stopped playtime. I think I need to re-shoot the calibration library - so as the clouds look like they're here for a few days, seems like an opportune time! And of course, I need to re-read Warren's Inside PI book. Again!
