  1. Hi, My EQ6 mount is old now. Very stiff RA and DEC axis, it's time to dismantle it and see how bad the inside is. I followed the Astro Baby guide and it was not any big problem to dismantle it. It looks fine inside, I suspect some earlier owner already have done this cleaning and put new grease on. But that must be years ago. When I now have dismantled everything, shall I rebuilt it and install timing belt drives? I feel it's a little to much money to put on this old mount. I have to think about it and see what alternatives there are. Here is my EQ6 dismantling story: http://www.astrofriend.eu/astronomy/projects/project-eq6-dismantling-rebuilding/01-eq6-dismantling-rebuilding.html Only first part, now I'm drawing plans. /Lars
  2. I scrapped all the Oiii and Sii data I previously took during a full moon (about 15 hours worth) and retook it all when the moon was a bit smaller at 76%. Ha was taken during 98% and 67% moon. All the lights were taken on the following nights: 12th, 19th and 20th September 2019. Integration times, all in 600s subs unbinned: Ha = 28.33 hours Oiii= = 5.67 hours Sii = 5.67 hours The Ha data is really nice, and unsurprisingly the Oiii and Sii is not as strong (or nice). I'm missing that (vital) step in my processing routine of getting the Sii and Oiii properly stretched to match the Ha, before combining. I dont really know how to deal with the weaker data properly. Any pointers would be appreciated. What I do currently: All the data is loaded into APP into separate channels/sessions. The data is stacked and registered against the best Ha sub This produces individual stacks of Ha, Sii and Oiii that are all registered Each channel is processed with DPP in APP and then saved as a 16bit TIFF Each is opened in PS Stars removed with AA and any remnants removed and tidied up I then open a blank RGB document in PS I paste Ha into Green, Sii into Red and Oiii into Blue Adjust the selective colour settings to get 'Hubble palette' Adjust levels, curves, saturation until looks ok All the Ha Sii Oiii data is then combined together in a single 'super' stack in APP using quality weighted algorithm to create a 'luminance' That luminance layer is adjusted using levels, curves, and NC tools such as local contrast enhancement and deep space noise reduction (using masks to apply as required) The luminance is pasted onto the above colour layer, and incrementally added using gaussian blur Cropped and saved. Here it is anyway I haven't intended on any more exposure time for this one, but will consider it, if the expert opinion dictates otherwise! CS Adam

  4. Background:Even though I'd really like one, it's not entirely practical or financially viable at the moment for me to have a permanent observatory in my garden.I therefore thought the next best thing is to build a pier - which should offer superior stability than a tripod and not take up much room.This idea was run past the wife and surprisingly approved without much fuss. When not in astronomical use it was agreed that the pier will be topped with a sundial in order to make it blend in a bit better.Since I was looking for a low cost option, I've taken the inspiration for the build from the piers at Todmorden Observatory, which I know a few other SGL members have also implemented.Materials for pier:M10 Stainless Steel A2 Threaded Bar (1m) x2 £10.46 Toolstation http://www.toolstation.com/shop/p79966M10 Stainless Steel A2 Dome nuts x8 £ 1.95 Ebay http://www.ebay.co.uk/itm/160881328576M10 Stainless Steel A2 Nuts x12 £ 4.49 Ebay http://www.ebay.co.uk/itm/181036635594M10 Stainless Steel A2 Washers x16 £ 2.69 Ebay http://www.ebay.co.uk/itm/360543852606440mm x 215mm x 215mm Hollow Concrete Block 7N x2 £ 3.30 MKM.B.S. https://www.mkmbs.co.uk/prodb004313-440mm-x-215mm-x-215mm-hollow-concrete-block-7n/Postcrete 20kg x3 £17.97 Wickes http://www.wickes.co.uk/Blue-Circle-Postcrete-20kg/p/221100Wood off cut (approx 20cm x 20cm) x1 £ 0.00Masonry Paint x1 £ 0.00TOTAL £40.86Tools:PencilRulerSpirit LevelDrillMasonry Drill Bits (5mm, 10mm)Wood Drill bit (10mm)SpannersSpade/TrowelSaw suitable for metalConstruction Instructions:Select a suitable site in your gardenDig a hole approx (30cm x 30cm square) x 40cm deep Cut the M10 threaded bar into 4x 33cm and 4x 10.5cm lengthsBend the M10 threaded bar 33cm lengths at right angles approx 8cm from one end (may need to heat them up to do this)Drill 4 holes into one of the concrete blocks using the 5mm drill bit, then go through again with the 10mm bitPlace the other block on top and mark through the holes with a pencil, then drill the second blockUse the 4x 10.5cm lengths of M10 threaded bar to attach the two blocks together using washers, nuts and the dome nuts on topDrill 4 holes in the base of one blockPut an off cut of wood on the block and mark through the holes with the pencilDrill the holes in the woodAttach the 4x 33cm lengths of M10 threaded bar using nuts. This is only temporary, since this is effectively a 'former' in order to ensure that the bars line up with your block holes when they've been set in the concrete Mix most of the concrete and pour into the holeInsert the 'former' ensuring that the underside nuts are not submerged, that approx 50mm of bar is above the concrete, and most importantly the 'former' is level Add more concrete if necssary & tamp down to make the top smoothWait until the concrete is set & remove the wooden 'former' Smooth out any unevenness in the concrete, ensure it is approx level and that the block fits onto the exposed threaded barsAdd a small amount of concrete & place the block on top, adding more concrete around the sides as necessaryMake sure the block is as level as possibleWait until the concrete is set and fix it into position using washers and dome nutsPaint the whole thingOther notes:You could use cheaper zinc plated threaded bar and nuts/washers, I selected A2 stainless steel for longevity and anti-rusting.Stainless steel comes in A2 and A4. A4 is generally more expensive and is mainly for marine use.Another option for the base is bolting it to some freestanding paving slabsAnother option for attaching the blocks and base together is using specialist glue
  5. I'm trying to update my v3 handset prior to selling the mount. I need to update the bootloader from v1.0 to v1.7 before I can upgrade the firmware from 3.12 to the newest version. I've tried following the instructions in the bootloader download but the upgrade loader refuses to install anything. Before I realised I needed to update the bootloader, the synscan loader v3.3 just showed 255 255 255 where it should display the handset software, ie 3.12. Can anyone advise what I'm doing wrong? The handset won't run the mount probably because I had a replacement motor control board a few years ago., I'm guessing. It worked fine before that. I've been using eqMod for years. Thanks. Anne
  6. I am going to upgrade to the skywatcher 250/1200 pds telescope and i can't decide which mount i should get. The main (only) purpose is astrophtography and i am considering either the eq6-r- pro or the cem60 The cem60 can carry more weight but is also more expensive, my inner debate now is about if it is worth it What's you take on it?

  8. Hi, I was looking at YouTube today and came across an upgrade for a Skywatcher EQ6/NEQ6 that makes setting the latitude setting easier.... See... http://www.modernastronomy.com/shop/mount-accessories/mkii-eq6wedge/ Has anybody done this upgrade? Cheers Adrian
  9. A very lightly used AZ EQ6-GT mount and tripod for sale. The mount is approx 3 years old and I am the second owner. It is in exceptional condition and as stated has been very lightly used by myself and previous owner. Reason I am selling, due to a change of job and working away significant parts of the week / month I have no time to indulge in the hobby at the moment. The mount comes with all the usual items, Mount and tripod, hand controller, cigarette power lead, eqmod usb lead, manual. Also included in the sale is the ADM losmandy / Vixen saddle and the regulated power supply - this one as per FLO website - Nevada PS-08 PSU Price is £995 ovno for everything. I have the box for the mount with original packaging but not the tripod, hence this is pick up only or can travel and meet half way by arrangement - I travel extensively so I'm sure something can be arranged. I accept cash, cheques and bank transfer (which is easiest to be honest). Paypal if the buyer pays the fees. The mount is currently in my observatory and can be seen working if you wish. The ES102 pictured is also for sale in the next ad! Thanks for reading and if you have questions please PM me and we can discuss in more detail. Neil.

  11. Took the bull by the horns and done the power modification on my Eq6 pro to connect via the 2pin connector , bit nerve racking haven’t really done much soldering before ,managed to do soldering without frying anything, used Blu-tac to isolate surrounding area so I didn’t solder anything I shouldn’t have , mount powered up checked slewing with handset , steady red light voltage reading 14v dropping to 13.9v slewing phew ?

  13. M13 - Great Globular Cluster in Hercules from 06/09/2018 22,180 light years away, 145 light years wide Quite a close crop on this due to its scale in my scope, but happy nonetheless. Looks like better flats are definately helping me out now when it comes to processing. The only thing I couldn't work out is the faint fuzzy at around 2 o'clock. With a bit more research it looks like it is the spiral galaxy NGC6207 (distance 30 million light years) - and VERY faintly you can just make out IC4617 (489 million light years away) TS65Q / Modded 1200D / EQ6 Guided - 83x30s

  14. I am looking for a pre-goto EQ6 for a project. Looking to spend up to £300 depending on condition. Phil
  15. Dear All! Please read everything!!! I have a big DEC backlash on my EQ3 mount near to 8000ms, and the pulse guide correction is slow and the 2000ms doesnt enough to correct this issue. So I decided to correct it with this great EQMOD project to add some new code in the backlash correction The plan was to use the slew direction to correct the backlash! WARNING!!!! this code works like the slew controls so its minimally override the DEC coordinates. Installation from zip file: 1. install AQESCOM - final version\EQASCOM_V200j_Setup.exe 2. Copy files from final version\common files\eqcontrl.dll to C:\Program Files (x86)\Common Files\ASCOM\Telescope or C:\Program Files\Common Files\ASCOM\Telescope, but make BACKUP first! 3. run EQMOD's toolbox and register eqmod.exe 4. Happy testing. In my case the correction ratio is 800 and duration is 290ms PS. Thank You for the developers to this great project!!! final version.zip
  16. Hi I recently bought a new Skywatcher EQ6 Mount, I found that the RA axis the movement of the mount is not free, i had completely unlocked the RA Lever lock and I have not connected it to any power, as i am located in San Jose, CA the Latitude is not too low for the Pole Star. I found the astro-baby site recommends the stripping down of the EQ6 mount and greasing it, but however want to know if i need to really do it for a new mount. I used to own Sirius mount for over 3 years and never had this issue. thanks BK
  17. hi i am looking for same parts for my neq6 3 yeas old , the part is : RA & DEC clutch locking bolt & bolt Screw ( i Loss it in Strip Down ) motor worm-gear ( Damage ) RA & DEC stepper motors please help me where can i find the parts?? best regards sam
  18. Sometime last year after completing a long session on the Crab Nebula, I turned my C9.25 to it and took a 20 minute Ha exposure at F10. The little bit of detail that came through made a big impression on me, and so I planned a kit upgrade to get a proper image done at that scale. One C11 EdgeHD and Atik428ex later, here's the result. My EQ6 is working at its limit, but performing admirably under the pressure of providing a stable platform for a rig running at 2800mm focal length. The resolution is really pushing it too, 0.67 arcsec/pixel, but I wanted to see what the scope could do, so any time there was a clear hour or two, another few subs were added to the total mix. I've really enjoyed this one, it has kind of made up for a dreadful year of weather and cloudy skies. I have a new reducer on the way for the scope, and possibly a new camera too, so will be looking for some new challenges in 2013. Full details below, thanks for looking.

  23. Hey guys, following on from my last thread regarding drift alignment issues, I finally (after a year and a half of trying) managed to get what seemed to be precise polar alignment using the drift method. The goal of this is to get long(ish) unguided subs. My setup is a Skywatcher NEQ6, SW 80ED Refractor, Canon 100D DSLR and i'm using BackyardEOS to control the camera. I don't yet have a focal reducer or any form of autoguiding. Here is an image of my altitude alignment (using the D.A.R.V method), using a star at around ±10° dec from the celestial equator, as near to the east horizon as possible. (Apologies for the poor image quality - I had to use my phone camera since print screen didn't seem to want to work on the laptop). And here is my alignment for the azimuth (taken near the meridian at ~0° dec). I spent hours trying to get both as precise as possible - I think more precise alignment would have been next to impossible for me to do. Regardless, after finally feeling like i'd got good alignment, I went to take an image and I was pretty disheartened. A 30 second exposure left me with significant star trails. The longest subs I could get without trails were ~15 seconds. After nearly a year and a half of just trying to get good polar alignment, it feels like a bit of an insult, especially given that people often talk about getting 30-60 second unguided subs. But, i'm determined to eventually get there. So my question is, why is this happening? Could it be that my mount is flawed or damaged from the time I dropped it on my head? Do I just not have enough practice making the small adjustments to the mount required for unguided subs? Could balancing play into this? I've tried to balance my mount as best I can, but the dec axis is still heavily skewed towards the back/camera end of the scope and i'm unable to move the scope any further forward on the dovetail to counter this. Or could this be that i've simply hit the limit of my setup? I was always intending on buying an autoguider once I was familiar with my equipment and able to get good polar alignment, but would it be worth it? I'm a bit worried that if I can't get better alignment, an autoguider really isn't going to make much difference (and at best give me bad field rotation). Alternatively, are there any other methods of polar alignment I could use? I don't really want to use the polar scope method, and would prefer drift alignment if possible. I'm aware that pHd has a drift alignment procedure, and i'm tempted to try it if I do end up getting an auto guider. Any help or discussion is much appreciated! Cheers, Crowmium.
  24. Night 1-first light Took me from 2100 to 2330 to set up all the software. Another Hour to setup scope, USB-2-serial, etc. No direct sight to polaris. Put up only rudimentary polar alignment (with compass), then astrotortilla for plate solving. Problem: as i had a massive polar alignment error, i was on target, but with a severe tracking error- exposures of only 5 seconds already showed star trails. Did a nice shot of M42 (orion nebula) nevertheless. (2 months break due to exceptionally bad weather) Night 2 No astrotorilla available as VM software did not start. Setup only 15 minutes, but another 45 minutes to remember how to connect camera correctly to scope (was out of focus because i had a extension in-between that was unnessessary). Setup again roughly to north with compass. Entered coordinates, date,time. Start three star alignment. 4 out of 5 suggested stars covered by house. Repeated 2 times, always the same invisible stars . Sweared. Tried 2-star align, the same. Tried 1-star align-success, much bigger list to choose from for alignment stars. Wondered why on earth the programmer did these inconsistencies. Selected first star, slewed. Far off target. Finally realized that finder scope not correctly attached. Corrected this. Slew speed way too low- another 10 minutes until realized that "rate" button sets slew speed also during alignment. Success. Slewed to second star, aligned. Back to first star and realigned. Back to second star - directly in the crosshairs, mount tracks perfectly (at first sight). Relief. camera mounted and connected to laptop. Start taking images. Relized that there is still some error, but significantly lower than on first try (Okay up to 10-20 seconds). Shot images for hours until Orion reached trees. Happy Next up: the mystery of tracking with second cam+PHD.... If i live to see the day that we have good weather again.
  25. Having ordered an altitude mod plate from Gunnar, I took the opportunity to do the work today. You can read my write-up at http://darrenjehan.me.uk/blog/skywatcher-eq6-altitude-mod/ Nice and simple and worked a treat. Need a clear night now to re-align and see how it well it works in practice, but have high hopes!
