  1. I would like to hear from people who use their Optolong L-Enhance and L-Extreme filters with dslr cameras please. How do you find using them, your results and compared to other filters available. Should I just stick with my IDAS LP4 Filter and see not much difference? I know the L-Extreme has a narrower bands. Thanks.
  2. The images are very deep, this I would want to image with my EVO62, just dealing with stupid problems atm. Its nice to see people imaging with affordable equipment.
  3. I have not claimed the weight to be 2.5kg, unless your reading from the official spec sheet. Actually the scope does feel just over 2kg even without the reducer added, that's for sure.
  4. I do fully understand, ideally you want something you will not need to fiddle with too much. I used Ekos quite a while on Ubuntu on a Mele PC, it worked well until recent upgrade with ekos then after that everything started to go wrong. I will look into NINA or go back and use Stellarium and backyardeos again. Maybe @RolandKol look into the TS range of premium newts or move onto ed refractors. However I will update this thread as I progress.
  5. I can tell you the Quattro is focuser heavy 2 locking knobs and zero shift or at least I have not noticed. I would say they are better than the standard dual speed skywatcher focusers, but if you want creme de la creme expect to pay more. I am currently using a DSLR, I cannot comment on if you were using a filter wheel as well and nor does the draw tube intrude into the light path as the 130PDS is prone to do. I was out last night dealing with the Ekos problems I was having after I updated the program. I do seriously love how Ekos is setup, but there seems always a problem with it after you update it, I think I will just defer back to windows - even though I do not want to. I have managed the balance better of the scope by using a 11" ADM Dovetail, but due to the above problems could not get any images off. @RolandKol What focusers would you expect on Skywatcher Offerings on 8" and 10" Newts? If you follow that path.
  6. Well, let's start with the appearance first. I was initially thinking to invest in one of those GSO variants but did not take a liking to the primary mirror collimation design at the rear of the scope. I did notice this scope at the time when I was buying my Evolux 62ED but held back a little bit. As, I was also wanting to replace the 130PDS with something faster than f5 but with a similar focal length. I also do own a Celestron OMNIXLT150 f5 Reflector and the StarBright XLT coatings are wonderful. What appealed to me was a Modified Aplanatic Coma Corrector was included with a reducing factor of x0.9, f/4 becomes f/3.5 at the focal length from 600mm to 518mm and one element is of an ED element. I have in the past owned a couple of f4 Quattro's one being the Carbon Fibre 8" which is no longer available. The scope being F4 you would expect the mechanics of the telescope and the mirror cells to be well made and stable, especially when temperature changes happen throughout the night. Also, I had read from the Skywatcher USA website the mirrors offer "Parabolic borosilicate mirrors utilizing Sky-Watcher’s proprietary Radiant ™ Aluminum Quartz (RAQ™) coatings designed for imaging with 94% reflectivity". What is that I do not know? Is it better than the coatings of my previous 130PDS? or better then StarBright XLT coatings on my XLT reflector I don't know. My collimation tools are a TS 2" Concenter sight tube and flo's premium chesire. Unfortunately, a laser does not cut it nor has it for a long time for me. I have found this method of collimation to be reliable then buying laser tech. The secondary size is 64mm wide and central obstruction is 42% or 18% of area. The rear of the primary mirror is exposed, if you find the need you need to cover it, a simple black showering covering cap from the local pound shop would do the trick. On the European models the stock quattro dual speed focusers are included with the two locking knobs without any eyepieces. On the USA versions they are equipped with stock Dual Speed focusers with an eyepiece from what I am hearing. In relation to some mods needed, would be a slightly longer dovetail for better balancing, replacing the focuser collar as it introduces tilt (as seen in image) with just having two thumbscrews and a black covering cap for the rear of the primary mirror. The scope itself is shorter than the 130PDS and stubbier weighing around 6kg with tube rings and dovetail fitted. Overall, it is a nice finish and made well. Now for the eye candy.... I did manage to get a short session last night, seeing was good initially then turned fair, after spending over 1 hour fixing an issue I had with my capturing software, I only managed to grab 30mins worth of data on double cluster, I can say for sure I found the tightness of the stars a lot better and cleaner compared to my 130PDS and just with a short amount of data, the star colour is looking good and better defined. The following shot was taken without calibration files on a 600D.
  7. A smelting new Quattro 150P with the included bespoke coma corrector.
  8. Its phenomenal, especially with a cheap 8" newt which does not break the bank.
  9. Those mirror clips can touch the mirror, but without pressure. They just need to be loose on the mirror. Their usually tight to make sure the mirror does not swing about while the scope is being shipped.
  10. A couple of months ago I got this out with a 2" revelation dielectric diagonal. Just viewing half moon. Sometimes I do visual as I feel lazy getting my gear out. I was using the skywatcher 2" 28mm let Eyepiece. No noticeable colour or fringing of colour was noticed. Seeing was fair. The views to tell the truth were very similar to the SW72ED I use to have, ever so slightly dimmer. I do remember the 72 having a slight better contrast maybe because you have another 10mm of aperture to play with.
  11. I am using the flattener and reducer with a Canon 600D which is a APS-C sensor. I am sorry but I can't comment if your using a sensor size of 35mm. The flattener/reducer yields pinpoint stars when using sensors up to 30mm. Blurb from FLO: "The flattener / reducer illuminates a full frame format and provides pinpoint star imaging over a 30mm image circle (sensor sizes up to APS-C)" Sky-Watcher .9x Reducer/Flattener for Evolux 62ED | First Light Optics
  12. Sorry to pull up this old thread. Can I ask what are the measurements of the concrete base and depth please? Thanks.
  13. Beautiful image, I like the colours and James must have helped as well.😬
  14. Taken with the Evolux 62ED and a 600D. ISO 800 24x300 with calibration files. The body of the nebula reminds me of Water Melon Red. There is a slight tilt issue maybe a cable was slightly snagging or something was tightened properly, shown on the right of the image. The previous night I was imaging the bubble nebula, everything in the image looks good.
  15. Thanks for this. Its a great help. Regarding the case, try the link below as I have migrated the scope to another case which can also fit the autofocuser and handle: https://www.cases-and-enclosures.co.uk/roc-cases-large-silver-flight-case-l680-x-w300-x-h190mmn-with-foam-insert Its illustrated here 7th post down:
  16. With the reducer you can image bright dso images like globs and some bright galaxies, small star clusters and a small amount of nebulas like M27. Unless you have a sensitive camera that's your limit.
  17. The fov is very close to a 130pds, nice images BTW.
  18. I have been meaning to get one for my 62 as well. I am thinking I would have to buy the additional esprit / takahashi bracket as the fitting would be similar.
  19. Never heard of it, but impressive object and image though.
  20. I have a celestron C80ED and C100ED with FPL53 both do not exhibit any blue bloat. The C100ED is a nice scope for imaging galaxies and globs, same similar to the Celestron XLT150 f5 Reflector i have. Couple the 100ED with a reducer brings it down to f7.6 , just add a sensitive camera into the mix and there you go, now you have a scope setup near to the starfield f7. Or couple the Reflector with a sensitive camera and a coma corrector - there you go - No CA, True Star Colour, No Bloat, No worries about what glass the scope has, you have a small central obstruction as the secondary is around 48-50mm how much that would impede on contrast I would think be minimal, compared to some secondaries which are around 63mm. A lighter scope for the mount. Just my 2ps worth.
  21. Another reducer which will work with this scope is a TS Optics : TS279RED.
  22. A 6" F5 Reflector is a formidable choice, be it used with a dslr or a sensitive camera, more buck for your money. The TS ones have a better coating on the mirrors compared to the skywatchers or if you can get hold of a celestron 150xlt Reflector the starbright xlt coatings were very good and nor do I follow the opinion the coatings are the same as the skywatchers. Mind you the TS Optics also get mirrors made by GSO. So I don't see any difference between a TS, Altair or Stellalyra.
  23. My 2ps worth: Fast scope, DSLR Slow scope, Sensitive Camera.
