  1. At this stage, I'm looking at getting the GM3000, as I will have room to move if I want to upgrade later on.
  2. Hi I had a CEM120EC that gave me the #$#@. It never performed well on my 14" telescope and I did have a SDE of 0.4 arcsec. I spent 6 months trying to get it to work and now its gone from my life, worst mount I have ever used, and its also my first heavy payload mount. Now I'm looking at new mount, does anyone of any reviews on either the 10micron GM2000 or GM3000 and the mesu 2000? Ben
  3. If you read on the cloudnights forums over in the US the CEM120 is pretty good. But its the encoder versions that is causing quite a lot of issues. I just sent mine back for refund.
  4. Messier 8 (Lagoon Nebula) and Messier 20 (Trifid Nebula) This is a 2 panel mosaic and one of my first attempts at doing one. The Lagoon Nebula is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula. The Lagoon Nebula is currently undergoing a period of active star formation and has already formed a sizable cluster of stars. NGC 6530, the extremely young open cluster formed from the material of M8. The Lagoon Nebula is estimated to be between 4,000-6,000 light-years from the Earth. Like many nebula's, it appears pink in time-exposure color photos but is gray to the eye peering through binoculars or a telescope, human vision having poor color sensitivity at low light levels. The Trifid Nebula is also an H II region located in Sagittarius. The name Trifid refers to its three-lobed appearance. Messier 20 consists of several different objects: an emission nebula, a reflection nebula, a dark nebula and an open star cluster. First image is HOO which is just Hydrogen and Oxygen. OSH Oxygen as red, Sulfur as Green and Hydrogen as Blue SHO Sulfur as Red, Hydrogen as Green and Oxygen as Blue HSO Hydrogen as Red, Sulfur as Green and Oxygen as Blue OHS, Oxygen as red, Hydrogen as Green and Sulfur as Blue Skywatcher ED72 HEQ5 Pro Beltmod ZWO 1600 with Filters HA 28 x 10min OIII 34 x 10min SII 28 x 10min Total 90 x 10min Total time 15hrs
  5. The Prawn Nebula is an emission nebula located in the Sagittarius Arm of the Milky Way. It has an apparent magnitude of 7.31 and is around 6,000 light-years from Earth in the constellation Scorpius, the region is about 250 light-years across, spanning over 3-4 full moons in the sky. The nebula was discovered around 1900 and it is a stellar nursery that contains a large number of very hot, luminous, young stars, formed out of the surrounding gas. I also made other versions by switch the colour around, let me know what you think, I don't see many people doing it. HSO OHS OSH Skywatcher 72ED HEQ5 Pro Belt mod ZWO 1600mm with filter wheel HA 3 hrs OIII 3.8 hrs SII 3 hrs Total Time 9.8 hrs
  6. This is my 2nd all NB image NGC 6188 is an emission nebula located about 4,000 light years away in the constellation Ara. The bright open cluster NGC 6193, visible to the naked eye, is responsible for a region of reflection nebulosity within NGC 6188. NGC 6188 is a star forming nebula, and is sculpted by the massive, young stars that have recently formed there. NGC 6164 also created by one of the region's massive O-type stars. Similar in appearance to many planetary nebulae, NGC 6164's striking, symmetric gaseous shroud and faint halo surround its bright central star near the bottom edge. This view spans about 5 Full moons. Skywatcher 72ED HEQ5 Pro Belt Mod ZWO 1600mm with Filter Wheel HA 4.3hrs OIII 4.5hrs SII 3.3hrs Total Time 12.1hrs
  7. I was looking at getting a mesu 200 shipped to Australia. But with the new elbow pier. Shipping costs would be very high. But i'm following the JTW OGEM mount now.
  8. Thanks for the responses. Spent the last few days going though tons of website. Looks like V groove tracks is the why to go. I can get 75mm, 100mm or 150mm wheel size. How much of a difference would there be in ball bearing wheels compared to plain ones? https://www.richmondau.com/wp-content/uploads/2017/05/Track-Wheels-V-Groove.pdf?fbclid=IwAR2DuIo9luUpH32faTf5W9cDmrhruL2_fQ_3pTYvpWD6Pm7pV1nv6GQcbGI
  9. Hi all I'm in the design stages for my backyard obs. I'm going to go with a timber shed with a colour bond roof. It will be 3m x 3m internally. I have attached a diagram which is almost finished of my shed and the diagram of my mount. The idea is to have the pier 700mm high off the floor and with a wall height at 1.6m and peak inside roof height at either 2m or 2.2m. At this stage I'm still deciding on going with a automated roof or push the roof, it has to move a 3mx3m timber roof. For the wheels would ball bearings be better and what sizes should I be looking at? Does anyone of any ideas what to go with? I would like to keep the motor inside if possible. The motor doesn't need computer control, I'm happy to push a button to open the roof. Ben
  10. Its a bit hard to make out in the 72ED as it lacks resolution. The running chicken is just to the left of the dark Bok globules
  11. IC 2944 (Running Chicken Nebula) This is my first Narrow band image IC 2944 is an open cluster with an associated emission nebula found in the constellation Centaurus, near the star Lambda Centauri at a visual magnitude of +3.1 and lies 420 light years away. It features Bok globules, which are frequently a site of active star formation. IC 2944 lies around 6500 light away from Earth and its around 75 lights years in diameter. Skywatcher 72ED HEQ5 Pro Belt mod ZWO 1600mm with Filter Wheel Ha 5.25hrs OIII 3.2hrs SII 3.0hrs Total time = 11.45hrs
  12. Work in progress on NGC 6188 going to do a hubble palette. Ha 6NM 2 hrs stacked only Also done a test 2x drizzle integration. SW 72ED
  13. I have the astronomik Ha 6nm filter. I have produced some great images with them.
  14. I just placed the order to get the complete LRGB and ultra narrow band set for Ha 3.5, OIII 4.5 and SII 4.5 to go with my new G4-16000 camera. But won't get the order until Mid July.
  15. The biggest I could find without spending 1000s$ on a flattener is the TSRCFlat3. Now has anyone used one? https://www.teleskop-express.de/shop/product_info.php/info/p6972_TS-Optics-Full-frame-size-Corrector-for-RC---Ritchey-Chr-tien-Astrographs.html
