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.
I purchased a GSO 6" f/4 Newtonian "Astrograph" late last year and eventually found that stars on one corner were egg shaped while taking images. I narrowed it down to improper centering of secondary mirror from the factory and resulting tilt.
Long story short, after numerous iterations, I used the Advanced Newtonian collimation technique by Astro Shed guy and ended up with the below pic of the optics. Does it look ok or do I need to do more? I will be checking with a Howie this weekend too.
Hi guys and gals,
I recently purchased a pair of Nikon Aculon 10-22×50 Zoom binoculars for around $179 and I'm pretty disappointed with them. I live in Semi-rural northeast Texas and was looking for a good pair of binoculars for a casual stargazer like myself. I thought these would be the perfect pair, I was wrong. The field of view is pretty small and the focus is annoying. The view is like tunnel vision at 10× and too dark at 22×.
Do any of you individuals have any helpful suggestions on what exactly I should get that suites my individual needs?
I am looking for something that won't break the bank (under $300), has a large field of view, would allow me to see the moons of Jupiter, the Andromeda Galaxy, starclusters, nebulae, and maybe some of the Messier Objects? Also, without a tripod needed. I would like something that is comfortable on the eye and easy to hold.
Its asking a lot, I know. But I'm hoping some of you who are more knowledgeable on the subject would be able to help me out?
Hello, I'm very new to the practice of astronomy and my interest is with deep sky objects, I very much prefer "goto" type telescopes. Im just looking for a decent set up for visual observations of dso's and I have no idea where to start to look, please help!
( 500$ budget )
