    NGC 6441 ZWO ASI 071 Pro

    Hi Adam The purple star comes from the ASI 071. Its how the bayer pattern detects it. Not much I can do about.

    NGC 6441 ZWO ASI 071 Pro

    NGC 6441 NGC 6441 is a globular cluster in the southern constellation of Scorpius. The cluster is located 5 arc minutes east-northeast of the star G Scorpii, and is some 44,000 light years from the Sun. G Scorpii also named Fuyue has an apparent magnitude of +3.19. It is approximately 126 light-years from the Sun. G Scorpii is an orange K-type giant which is about 16x bigger than our sun. GSO RC 6 ZWO ASI 071 Pro HEQ5 Pro Belt mod 4min x 31

    M 83 Zwo ASI 071 Pro

    Version 2, I did this object last year. So I decided to revisit and put in more data with my upgraded version of this camera. Messier 83 also known as the Southern Pinwheel Galaxy is a barred spiral galaxy approximately 15 million light-years away in the constellation Hydra. It is one of the closest and brightest barred spiral galaxies in the sky, making it visible with binoculars. GSO 6" RC HEQ5 Pro Belt mod ZWO ASI 071 Pro 57 x 4 min = 3.8 hrs

    NGC 3603 ZWO ASI 071

    NGC 3603 is a nebula situated in the Carina spiral arm of the Milky Way around 20,000 light-years away from the Solar System. It is a massive HII region containing a very compact open cluster. NGC 3603 is the most massive visible cloud of glowing gas and plasma, known as a H II region, in the Milky Way. The central star cluster is the densest concentration of very massive stars known in the galaxy. Strong ultraviolet radiation and stellar winds have cleared the gas and dust, giving an unobscured view of the cluster. NGC 3603 is visible in the telescope as a small rather insignificant nebulosity with a yellowish tinge due to the effects of interstellar absorption. In the mid-1960s, optical studies combined with radio astronomical observations showed it to be an extremely strong thermal radio source. Later observations of other galaxies introduced the concept of starburst regions, in some cases whole galaxies, of extremely rapid star formation. NGC 3603 is now considered to be such a region.

    HEQ5 Pro Belt mod issue

    Bit of an update. I think I have sorted out the mechanical issues. Doing a quick test run last night over 3 hrs. I did to objects The 1st object was around 70 deg alt guiding was good. I got it down to around 0.6 RMS. Doing 5min exp at 2 sec guiding. The 2nd object was at 87 deg so almost straight overhead this is when problems started to show. Every so and then something moved, I think I have narrowed it down to my guide scope. I heard it creaking and saw the Ra shutter. Don't know if this is the problem or not. I will really tighten up my guide scope now. Doing 2min exp at 2sec. For those you say I should go to OAG, I haven't had any issues on the worm gears and I'm waiting for my new guide cam and OAG to arrive.

    HEQ5 Pro Belt mod issue

    Thanks Hallingskies, My total weight is around 8kg. Still under the 12kg for imaging. I shoot at 1370mm FL, Polar alignment is good as I can get it. I can get upto 15min guiding with round stars, but im hoping to see if I can get the graph more flatline like a belt drive should be.
  7. I just recently got a belt mod conversion for my HEQ5 Pro, the guiding is much smoother then it is. But I was expecting a flatter line. I don't have much mount experience or using PHD2, but can someone point me in the right direction to get this issue fixed? The 2 sec graph shows bad RA oscillation while the 1 sec the RA is more smoothed out. PHD2 has the correct focal length and pixel size. EQmod pulse guide is at 0.30 same in PHD2. The mount is balanced using the 90 deg angle method. I am using a guide scope. Is it a PHD2/software issue, or is it a mount/motor issue? Ben

    M 104 ZWO ASI 071 Pro

    Hi, Yeah the HEQ5 pro handles the 6" well, It could even handle a 8" carbon fiber if a go with OAG.

    M 104 ZWO ASI 071 Pro

    Messier 104 also known as the Sombrero Galaxy, is a majestic unbarred spiral galaxy located in the constellation Virgo. The Sombrero Galaxy has an apparent magnitude of 8.98 and lies at a distance of 29.3 million light years from Earth.The galaxy has a diameter of approximately 50,000 light-years 30% the size of of our own galaxy. Messier 104 has an incredibly bright nucleus, an unusually large central bulge, and a conspicuous dark dust lane in its disk. The appearance of the galactic bulge and the dust lane that crosses in front of it have earned M 104 the name Sombrero. The dust lane has the shape of a symmetrical ring around the bulge. The Sombrero Galaxy’s large bulge and supermassive black hole at its core make the galaxy a popular target for study. Messier 104 has a large population of globular clusters. Observations have yielded estimates in the range from 1,200 to 2,000 globulars. GSO 6" RC HEQ5 PRO ZWO ASI 071 Pro 23 x 5min = 1.9 hrs

    NGC 2467 ZWO ASI 071 Pro

    NGC 2467 is a star-forming region, popularly known as the Skull and Crossbones nebula. Whose appearance has occasionally also been likened to that of a colorful mandrill. It includes areas where large clouds of hydrogen gas incubate new stars. Located in the southern constellation of Puppis, with an age of a few million years at most, it is a very active stellar nursery, where new stars are born continuously from large clouds of dust and gas.

    Hi Andreas I shoot at full focal, on my little 6" you cannot use a focal reducer is it will cause serve vignetting. Ben

    NGC 6362 ZWO ASI 071 Pro

    NGC 6362 is a globular cluster in the constellation Ara, lying close to Apus in the southern sky. Tightly bound by gravity, globular clusters are composed of old stars, which, are around 10 billion years old, and much older than the sun. These clusters are fairly common. there are more than 150 currently known in our galaxy, the Milky Way, and more which have been spotted in other galaxies. All stars are usually around the same age in a given cluster. Most of the stars inside the cluster are thought to have formed at or around the same time and are thought to be of similar age. Most of the stars inside NGC 6362 are red giants that appear yellow and aged, however, you also see a number of so-called blue stragglers, stars that appear younger than their true age. Blue stars are hot and consume their fuel quickly. GSO 6" RC HEQ5 Pro ZWO ASI 071 Pro 17 x 4min = 68min

    UY Scuti ZWO ASI 071 Pro

    Did this Early this morning. Something quick and easy plus a test. UY Scuti is a red supergiant star that can be located in the constellation of Scutum. The star can not be seen by the naked eye, you need a telescope to see it. UY Scuti is one of the largest giant stars in the milky way, to put it in context, if the centre of UY Scuti was where our Sun was, the star's radius would extend out to Jupiter or even as far as Saturn. The diameter is about 2.4 billion Km!!! Or about 1,710x bigger than our sun. UY is a semi-regular variable star in that it expands and contracts on an irregular base. The star roughly pulsates about every 740 days.It will go supernova one day but even though it is a large star, it will not go supernova in the next million years because it has to work through the elements in its core until it gets to Iron. After Iron, it will not be able to continue to fuse elements any further GSO 6" RC HEQ5 Pro ZWO ASI 071 8 x 3min

    NGC 2070 ZWO ASI 071 Pro

    The Tarantula Nebula has an apparent magnitude of 8. Considering its distance of about 160,000 light-years away, this is an extremely luminous non-stellar object. The nebula resides on the leading edge of the Large Magellanic Cloud. The Tarantula Nebula got its name because its glowing filaments of dust resemble the legs of a spider. It is a giant starburst region where the energy from the bright, hot young stars creates huge voids and filaments in the surrounding clouds of gas.

    IC 2948 ZWO ASI 071 Pro

    IC 2944/2948 Known as the Running Chicken Nebula, is an open cluster with an associated emission nebula found in the constellation Centaurus. It features Bok globules, these globules are small dark nebulae that contain molecular hydrogen gas as well as helium and variable amounts of silicate dust (usually around 1-3%). The globules are associated to star birth, and quite frequently (about 40% of the cases.) They provide double or multiple stars. However, no evidence for star formation has been found in any of the globules in IC 2944. IC 2948 is the bright emission and reflection nebulae, while IC 2944 is the cluster of stars and surrounding nebulosity stretching towards λ Centauri. The Running Chicken Nebula, spans about 70 light-years at the nebula's estimated 6,000 light-year distance. GSO 6" RC HEQ5 PRO ZWO ASI 071 Pro 31 x 4min = 2hrs
