I was not thrilled with the MPCC, which is why I decided to go for the Skywatcher which set me back $285. The collimation and centering of the optical chain is not perfect, but not that far off. For these first images I was also giving my SX M26 it's first run. I want to add an extra picture from the first light with the Quattro. Here is my first light test of the Quattro. 2" DUAL-SPEED LINEAR POWER FOCUSER: The new linear power focuser moves the drawtube using rollers rather than a rack and pinion for smooth precise focus adjustment. Good stuff. The location was a fairly dark spot at my parents summerhouse in Denmark. Thank you for this excellent review. Previously the Baader gave me lots of reflections when shooting bright stars. The Sky-Watcher Quattro series are premium quality imaging Newtonians with a wide field of illumination and fast f4 focal-ratios. So Celestron PowerSeeker 127EQ, while being a cheaper option, tends to get more favorable ⭐ reviews than the $610 SkyWatcher Quattro Imaging, as seen on the chart below. All shots were done using a Nikon D700, EQ6Pro and guided with PHD guiding with the Orion SSAG. The primary was a nightmare to collimate and didn't stay in position. I think this is due to the large pixels. He was surprised of the reduction of the CC and spoke to Skywatcher. I'll post one anyhoo. However, I would recommend collimation prior to every session. A few have reflocked the interior - some remove the baffles completely. The optical center is not far from the physical center. My 8" F4 GSO had one or two outings when I first got it and things didn't run smoothly. They say the CC is not made for the Quattro, and that they are working on releasing a coma corrector specifically made for the Quattro - very interesting indeed. (Nikon lens @20mm). Coco, of course it's ok to play with the data. They say the CC is not made for the Quattro, and that they are working on releasing a coma corrector specifically made for the Quattro - very interesting indeed. Both have received an identical stretch. The Quattro also has the steel tube for £200 less than the carbon. This was almost certainly down to the rings since it never occurs with other scopes. It's easy! But they also deliver a good image quality for observing moon and planets. The bottom left hand corner of the Quattro image shows elongated stars and this is more evident still with the GSO. GSO primary adjustment. Sign up for a new account in our community. I am very happy with the telescope and the first light. About 3 years ago I bought an F4 GSO newtonian with similar design features which I have hardly used and was interested to compare the 2 scopes. Further focal reduction seems to be the coming thing: Boren-Simon 8' f/2,8 Astrograph - für CCD & DSLR Kameras - Carbon Tubus. The focuspoint is also perfect for DSLR cameras. Have invested in Bob's knobs for the secondary, now need to work a LOT on the (rather useless!) Both scopes had smooth 2 speed focusers although I preferred the feel of the Baader on the GSO. Collimation guru, TJ, identified a very small rotational error with the secondary which he corrected. Highly appreciated. By Due to very high humidity I only managed to get 90 minutes of the Veil before the optics drowned in water. I should point out that the later ones had a wider tube, reducing vignetting (though the other specs are still out there. Continued use of SGL indicates your acceptance of our cookie policy. Below I have posted the combined data using both scopes and couldn't resist adding some old Ha taken with my QSI 532 and FSQ. CCD inspector can also be used for live collimation, but I haven't tried that yet. Rotating the laser around the draw tube saw the beam stay within the small centre circle on the primary mirror suggesting that the focuser was accurately mounted on the tube. Are you absolutely sure of that effect? At £399 the steel tubed Quattro is a stunningly good buy but imagers averse to repeated focusing may feel the extra £200 for a carbon tube is worth the extra. I am looking forward to more of your pictures. But OVL (Skywatchers UK distributor) advertise the Skywatcher CC as "Optimised for Sky-Watcher fast-ratio f/4-f/5 Newtonian Reflectors/Dobsonians". If using a dew shield I have been advised that a 10" shield with packing around the end of the tube would be less likely to induce vignetting. The GSO wasn't thrashed at all and optically was the equal of the Quattro. After collimating the telescope I made some test shots on the double cluster in Casiopeia swapping between the two coma correctors. Sign up for a new account in our community. Fortunately there is the moderately priced Baader Multi Purpose Coma Corrector to address this problem. I needed to use some shims to get the 55mm spacing between chip and the back end of the focuser and it still wasn't quite right. Btw. Since this is a fast telescope I was excited to see if my current coma correctors would do the job. Both scopes delivered tight round stars although the differential flexure with the GSO produced a little deterioration in the aspect ratio. The SX M26C is a OSC APS 10mega pixel camera with a pixel size of 6 microns. A 2" dual-speed 10:1 ratio focuser is included for excellent focusing precision. When the collimation is done right you unly need to check and maybe once in a while adjust the primary a bit. This scope is designed primarily for imaging, having a fast parabolic mirror with an enlarged secondary moved down the tube to ensure plenty of back focus and a wide field of illumination. Once learned (either by trial and error or from an experienced fellow astronomer), collimation is not a hard thing to get right. Share TS … There are a couple of fairly tight doubles in the image which are resolved equally well by both scopes. I mainly see the collimation as an advantage, as you can always adjust your scope to make it perform as good as possible. Mine came with a Baader Steeltrack focuser which seems to be of good quality. By using this site, you agree to our Terms of Use. I thought it was the TS that came with the wider tube and monorail focuser (quite a bit more expensive. The Nikon seems to have performed exceptionally well, lovely star colour throughout. The temperature was between 14-12 degrees C and the humidity was very high. Skywatcher Quattro-10S - 250mm f/4 Dual-Speed parabolic imaging Newton telescope Skywatcher Wide Photo Telescope line ... Asterion Primary Mirror Fan for Skywatcher 10" Newtonians and Dobsonians : Cleaning & Collimating: TSBARLA. Amazingly accurate right up to the very corners of the field. Start by squaring the focuser, center the secondary in the sight tube, tilt the secondary to aim at the circle on the primary, adjust the primary to center the dot in the circle - use the scope :-). I was imaging during a warm evening with very little temperature drop. I wanted to try this camera rather than my usual mono camera to see how well the scopes illuminated the APS sized sensor. It's easy! The reduction is expected to be seen with the 8 inch'er as well. The focuspoint is also perfect for DSLR cameras. I am very interested to see that the Skywatcher CC reduces the tube by 0.9. Additionally, the tube length has been slightly shortened to optimize performan Copyright © 2019 Stargazers Lounge Again 10 minutes subs ISO800. Looks like you're getting some lovely shots . The MPCC is a 2-element design that runs about $215 while the Skywatcher is a 4-element … Collimation is particularly critical with a fast scope of this type. The advantage of carbon is weight and thermal stability. I picked up a Aurora Flat-Field Panel recently so I'll be able to post a flat from mine to add to the comparison if ya like The forecast is good for tonight so I should be out with it. It's probably a bit easier to put a heating strip on a lens than on a mirror - but this is a minor thing. Following TJs advice I had a good look at the secondary position and was able to give it a little tweak. Not that the current CC is bad - it seems to work OK, but smaller stars and absolutely zero coma is always welcome. Sky-Watcher 10” f/4 Quattro Imaging Newtonian Telescope The Sky-Watcher Quattro is a fast f/4 Newtonian telescope with extra features that make it a really nice OTA for imaging as well as wide field visual observations with the addition of its dedicated coma corrector (sold separately). I'd love to see how a modded D700 would work. Stacked in DeepSky Stacker using the median method. These stand as an encouragement in themselves.
