  1. Thank you Scott. I will certainly look at basing my PHD settings on your suggestions. Certainly sounds like significant differences, gives me hope on improving my guiding. Just need some clear skies...
  2. Hi Scott., I managed to get out last night and test the mount. Other than a few niggles such as new SGP profiles needing filter wheels re-adding (my fault) then things pretty well. Following my usual routine I Polar Aligned though the Elevation bolts namely the spring loaded one is interesting. When I wanted to come further down in degrees I loosened it off but found I needed to manually move the mount forward to actually bring the elevation down if that makes sense. I should re-read the manual as I didn't spend a lot of time on this, anyway I got good PA. After focusing I used the handset and typed in dates and time (having to keep remember putting handset into EQ Direct mode!) Elevation was already there just entered through Polar Alignment section. Said No to align. Plate Solved at Polaris area. Then opened SGP and used a Slew now to get to rough area. Then used Center Now. First plate solve was out as normal, Second attempt was spot on, I think it was a single pixel out! Normally on AVX I had a max of 28 pixels so that was encouraging. BTW I am using Plate Solve 2 (no Internet access) and I have ANSVR setup with local copy as you describe. I find Plate Solve 2 always works. Began PHD and configured guiding. Despite changing the PHD profile to the new mount some of the settings were clearly not correct compared to the old AVX. Namely calibration steps. After I received "Star not move enough" I checked the Brain icon and noted this was recommending a way high value than previously, 6100 whereas it would have been around 700. Re-ran and this time it worked. Guiding started off woeful. Kept changing settings and by the end of the night I was around 0.90RMS. However much of the evening was way, way above this. My payload is only 16 pounds. The values I ended up with were as below. I suspect I will need to fine tune these but if you have any suggestions on value then that would be much appreciated. Not had to play around with PHD2 values for a while and I now remember how challenging it can be to get the best results. All in all a good night. Everything worked but needs fine tuning.
  3. Hi Scott, Thanks for your post. that's given me great reassurance. Last night I ran some tests to simulate my current routine and the mount appeared to behave exactly as I wanted it to. Obviously I cannot perform a plate solve inside but it gave confidence that I am on the right path. A couple of questions though. I will be buying the EQ Direct cable soon but even with the handset /cable how do you tell the mount the date and time? I guess this is what I have entered into EQ Mod already? The handset knows my latitude /longitude is that also passed to the mount itself? Secondly the handset keeps asking me about Polar co-ordinates which I have just entered through, is that okay as I will be Polar aligning with my Polemaster? Lastly the manual keeps referring to Alignment points. But I see no alignment points in the Alignment Point List Editor window. Is this simply because I have not added any and I wont need to add any as I will be using Plate Solving? That RMS figure sounds great. My current setup is way below half the weight of yours so hopefully I will be able to achieve the same sort of values. Hopefully will post results when I get some clear skies. Thanks
  4. Thanks Micky. Yes will be getting cable very soon (next week I suspect) but just wanted to get a idea of what to expect as things can get confusing when in the dark trying to sort this. Also cannot fully test plate solving until outside. So if I Pole Align with my Polemaster. Then use SGP to Plate Solve at Polaris as a means of creating an alignment point in EQ Mod then this would the same as performing a 1 Star Alignment? I would then set this as the Park point as well. This is what I did with the AVX before doing the Quick Alignment option on the AVX handset. After this I would then perform a solve and synch plate solve in SGP for the target image, preloaded by me. Also do I need the other ASCOM SkyWatcher SynScan Mount Controller (6.0.6262, June 2017) , is this as well as the EQ Mod EQASCOM driver? Thanks
  5. Hi. I have just received my new Sky Watcher EQ6-R Pro mount. Being new to Sky Watcher mounts means I am having to learn a few extra things but hopefully I can get up to speed quickly. Since receiving the mount I have updated ASCOM to the latest version, installed the EQ Mod EQASCOM driver successfully. I am currently using the Syn Scan to connect to the mount and laptop so using PC Direct Mode. Will get the EQ Direct cable soon.. I have managed to get everything to connected up correctly, so far so go. With my old Celestron AVX mount I would use my Polemaster to Polar Align then use the Celestron Handset to perform a ‘Quick Alignment’ after having inputted time and date. No need to actually line stars up in reticules just literally press Quick Alignment I could then use my Plate Solving in SGP to go to the target and begin imaging. I will of course still be using my Polemaster. But with the Syn Scan there does not seem to be any sort of Quick Alignment option. There is a 1 Star, 2 Star and 3 Star alignment options. How do I use EQ Mod without having to aligned any stars up? Surely it needs some sort of map built up even if it is not accurate. I am sure this can be done but not sure what I am missing? Note. I have not installed the ASCOM SkyWatcher SynScan Mount Controller (6.0.6262, June 2017) . Do I need this as well as the EQ Mod EQASCOM driver? Thanks.
  6. Very nice. Lovely colours. What exposures? Not long if it was in one night which is even more impressive!
  7. Nice image with some good structure, personally I would lighten the background a little but just my preference. It also states "Eastern Veil Nebula 2019" is that intentional?
  8. Thanks will revisit TIFFS for PS. Certainly a challenging hobby!
  9. Thanks again Graem. I do some final work in PS and occasionally drop back into PI though I realise I am out of the XSIF file format. My skills in PS are limited so what you describe is daunting but certainly makes senses. Will start off with basics and work from there. Out of interest what file format do you use in PS. If I use TIFF then the image brightens up considerably so I use PNG.
  10. Couldn't resist having a quick go! (Added to my first post) Not much brighter but if I push it too far it becomes too apparent. Anyway I will consider the effects of HDR more scrupulously in the future.
  11. Hi Graem, Thanks for the comments. No problem with pointing out suggestions and I really appreciate the feedback. I agree with you that I have over done the HDR. The original output was very bright with little detail and so was aiming to reveal the columns / pillars of gas located within the nebula, the end result does however lack depth. I did ponder this at the time as I really wanted to obtain that detail, looks like I went too far. I will see if I can edit it to a better result or come back to this when I have obtained some O3. Thanks you everyone's comments.
  12. Thanks Rodd. Yes the mono look can really bring out the detail. Still would like to add more Ha but at least with O3 I can produce a colour version. I will get an SII filter at some point but the Chroma 3nm are £485 and having barely had chance to get O3 it will have to wait a while.
  13. Whilst waiting for the California Nebula to rise to a decent altitude I thought I would try out NGC7822. This is a 6 hour Hydrogen Alpha image. I would like to add some O3 to the image but will have to see if the weather allows this. Please click the image as the preview loses a lot of detail..

Flats & BIAS Processed in PixInsight Revised 14.10.18 - Brighten Core
  14. I have the Chroma Ha & O3 3nm. Purchased them from Bernard at Modern Astronomy. https://www.modernastronomy.com/product-category/filters-wheels/chroma-filters/ Copied this from the Modern Astronmy website: "Try the Astronomy filters professionals use at many major observatories, NASA and JPL – Chroma! In business for 24 years and experienced in many scientific disciplines, Chroma has made filters for several US “famous name” companies, but now operates under its own banner in the Astronomy field." Have been very pleased with them though I have never had Astrodon's to compare against. I went for the Chromas as they offered the ability to placed them into an ASI 1600 filter wheel, whereas (apparently) you could not do this with the Astrodon's? I think they are worth the money no halos and stars are easier to control.
  15. I use PI and after a steep learning curve I am starting to achieve some satisfying results. But be aware my first outputs from PI were terrible. Take you time and save separate project files so you go easily go back and try other settings. I spend a lot long on post processing that capturing the original data. This can range from 5-10 hours in ,most cases. This may seem crazy and maybe down to me to still learning PI but I have found the results very rewarding.
  16. Thanks for the tips, I will have a look into this.
  17. Thanks. I have tried deconvolution in the past but found it offered me no visible benefits. Clearly I am missing something and will have another go at the deconvolution process. When I look at other similar exposed images on similar equipment their images seem a lot sharper. My image above looks like it has lost a lot of detail until you click on it, I suppose that's the forums display method. If anyone have any further tips on sharpening in a Pixinsight then much appreciated.
  18. Manage to add some O3 data to my previous Ha data captured from last year. The Veil Nebula certainly contains a lot of O3 as the pre-processed sub was nearly as bright as the Ha. I seem to struggle with sharpening without introducing more noise, this is true with all of my images. 6 Hours is not especially long so maybe more subs is the answer?

  19. Thanks. I find them to work well with my setup. Stars are quite easy to work with no halos.
  20. Despite the recent good weather we are experiencing in the UK I have not had many opportunities to go out imaging. As the Pelican Nebula is well placed I thought I would give it a go, would be nice to get more subs. Decided on an RGB blend. Scope: William Optics Star 71 Mount: Celestron AVX Camera: Moravian G2-8300 – Mono Filter: Chroma Ha 3nm, OIII 3nm 7x1800s exposures (3.5 hours) at -25c 3x1800s exposures (1.5hours) at -25c Total 5 hours.

  21. Have been watching these videos for a few years. Try and find the videos when they goto the VLT in Chile. Amazing location .
  22. I too tried to use Meta Guide but I failed to improve my guiding. Probably me rather than the program as it sounds like a well thought out idea but sadly not for me.
  23. I also had a great time viewing the moon on Sunday night. I am usually an imager but made a promise to myself earlier in the year to get back to basics and enjoy some visual astronomy again! Had a good look at Posidonius, I could clearing see two rilles running across the crater. Then spent some time at Lacus Mortis observing the rilles within its perimeter. Worked my way up the terminator and took in Rupes Altai and of course the stunning Theophilus crater. Lastly as it was nearby I went over to see if I could spot the Apollo 11 landing site. After many comparisons with various books I am 99% I got the location. The precise location is distant from any significant craters (well in mind it is!) making it more difficult than I had anticipated. You can see why they chose the location for its barren landscape, resulting in a safer landing spot. Though of course in reality I understand that there were many large boulders and craters that had to be negotiated before landing. All in all, a good night.
  24. Love the colours, what blend are you using? Is the reworked image a crop of the original or a new one? If its a crop then it has retained alot of the nice details.
