  1. I started getting better skies , getting my old mount problems are an ongoing thing that I deal with nightly . I ran tests in the frigid temps. on ngc1977 and IC434 and the Flame to get a handle on it and get my Moonlite mini v2 control setup in SGP. I've been reading the Astronomical handbook on imaging and processing and I think my images are making improvements , 1977 is out of focus on my colored channels due to trying to do it by eye. I didn't get sgp to run a sequence until 3 nights later and now I've got rain. This is the 1st time running on these targets, colors aren't correct but, they're improvement. I would add the # of frames but, they're all different and good enough to get my settings set and they're going to pop when I make a run on them . I'm really excited that I could get this and to have a test like this after being beat to death for months trying to get the PO'MAN rig working like this.
  2. stepping beyond

    HH , IC434

    This is the 1st test night for this disabled AA with my new moonlite auto focer mini v2 control ,1st time collecting data on the Horsehead nebula with any camera that I've owned , {30s } 25 frames luminous and 10 red channel combined in AIP4win and PScs2 , astronomy tools . I used an asi 174MM cooled -20c Zwo mini 5 efw , 8 in astrograph , lxd55 mount guided with Orion 50mm mini w/ helical . Captured in Sharpcap live stacking , I'm 0n my way finally got my autofocus set up correctly in Sgp to run a sequence later that week . It's a great feeling when everything is working together.
  3. heyyyyy its meeeee, kronosss and today there is a full moon(i missed out on the eclipse because of clouds... huh i guess i gotta wait another 19 years...)and i went out in the b ackyard with my 3" reflector telescope the celestron firstscope! The seeing was kinda bad... the full moon had less detail than the quarter.... anyway i figured i could see something else then i turned left and i saw orion(book-pun -intended) and the stars were quite faint(bad seeing full moon and light pollution.) i tried locating the orion nebula, after some time i stumbled across a small extremely faint smudge just barely distinguishable, then i turned and zoomed in,(75x) i saw 2 small kind of blurry spots of light (focusing wasnt great andi have the worst 4mm eyepiece in history...) with a very faint dark grey light around them keep in mind i saw that light when not looking directly at the nebula(read that it makes light appear brighter somewhere, it works lol) sooo is what i am seeing indeed it? or are my eyes playing tricks on me? Cheers Kronos
  4. Heyyy its meee kronos and i have been wondering about getting a filter...I really want the best contrast and brightness i can on my nebulas(i want to view M42 M57 M27 M31 M81 M82 and lots more) with my future 8" dob. Is this filter really going to help me? https://www.firstlightoptics.com/uhc-oiii-visual-filters/es_uhc_filter_125.html If it just a matter of quality of the filter itself can you suggest a better one in the same price range? Or will not the uhc filter help me in general .IF so can you reccomend another one? Also is this https://www.firstlightoptics.com/uhc-oiii-visual-filters/uhc-filter.html this https://www.firstlightoptics.com/uhc-oiii-visual-filters/es_uhc_filter_125.html https://www.firstlightoptics.com/uhc-oiii-visual-filters/baader-uhc-s-filter.html this better?
  5. Spent the last three nights imaging these three objects. Managed to get them all in the same frame of my ES 102mm FCD100 scope. Pretty happy with how it turned out. I would have liked to have grabbed a little more SII data. When I originally captured it, I thought I might only have two clear nights, so I imaged it as HA/OIII. Turns out there's almost no OIII. On the third night, clouds were supposed to roll in about 4am, cutting the imaging session short, but it stayed clear the whole night, and I got a full night of data with the exception that I got a late start due to technical issues when I first started imaging. The ASI1600's halos are rearing their ugly heads on the two brightest stars. I tried to tone them down some by desaturating the colors around both stars...it worked a bit. Another 15 hours and I could probably get rid of any remaining grain, but just don't have the clear nights to get it done. 15.8 hours total imaging time.

  8. Hi Guys, I thought I would share with you my first DSO taken with my new Orion 8" Ritchey Chretien F8 Telescope. The frame is made up of 12 x 4min shots, no light or dark frames, using my Sony A7Rii camera. The camera had the long exposure noise reduction switched on, which does help to reduce the total number of stars captured by the camera, as the Sony A7Rii does tend to overdo the number of stars captured. The telescope was mounted on my trusty skywatcher NEQ6 mount and the guiding was via PHD 'of course' via my skywatcher ED50 guide scope. The shots were taken from my back garden in Stowmarket, Suffolk where I believe I am a Bortie 4 location, so the skies are mostly dark, with just a little light pollution from the main town, no filters used. My normal telescope is a Skywatcher ED100 Pro Esprit F5.5, which is an incredibly sharp scope, but with a wide 550mm field of view, great for capturing the whole of Andromeda but a struggle with smaller images like the Iris Nebula. I will say the Orion RC scope did need to be collimated out of the box, which was a little disappointing, and it was not just a little out of collimation, it was a long way out, but with the use of a collimating tool, I soon had it dialled in. First impressions of the Orion Ritchey Chretien 8" Telescope are fair, not super impressed, as it is nowhere near as sharp as my ED100 Esprit, but then this is to be expected based on price and telescope type, however, the pictures it has produced are pretty good, if you downscale the full 42MP from the Sony A7Rii camera, as can be seen in this picture. I purchased this 8" Orion Ritchey Chretien OTA mainly for Planetary work, but as yet I have not had a chance to 'get onto' a planet, fingers crossed some clear nights will arrive soon, so I can try. I welcome comments, many thanks Jamie

  14. Greetings everyone. Few months ago I wrote a post about a small refractor to mount on a Star Adventurer, but I'm now considering fast tele lens like the Nikon 80-200 f2.8. My question is: what is the best tele lens to get pictures of Andromeda galaxy, Orion, Soul, Hearth nebula and stuff like these? If I'd pick a 70-200 f2.8 lens, can I plug a teleconverter 2x to get better crop without losing details? I've attached a picture taken with my Nikon D3300 and 18-105 kit lens, as you can see it's quite small (forget about the quality, it was also quite foggy back then). Thanks in advance.
  15. Hi all, As I'm slowly going through my data from July, this time I processed the RGB data of the Swan Nebula. This Nebula can really use a bit more magnification, so now I'm thinking of revisiting it with my SCT next season. At this focal length it's too small, but 1280mm or 2032mm through the 8" SCT should make it more impressive. I still have the narrowband data to process so hopefully the SHO image will turn out more dynamic. The total exposure time on this image is only 55 minutes, 20x60 second, 12x150 second and only 1 of 300 second subs, all at ISO1600. Taken with a modded 40D through a 80mm refractor at 500mm FL. Clear Skies, MG.
  16. Hi Guys/Girls I had a chance to get out in the garden last evening, had a go at capturing NGC 7023 - Iris Nebula, only managed to get 12 good shots, 240sec x 12, combined in Photoshop with Mean Stacking. The dew was super heavy and currently I do not have any dew heaters (next purchase) so lost the battle after around 2 hours. One interesting point is I captured these shots with the long exposure noise reduction switched on with the Sony A7Rii, so each shot took 8 mins to take and save, but as a result the noise levels were next to zero at 800 ISO, and at the end of the day the noise is always our enemy. I need to try a real pro level 'cooled' astro camera just to see how much better it could be, as the Sony A7Rii is just stellar ! I am very happy with the final shot, taken with my Skywatcher 100 ED Pro Esprit Scope on my NEQ6 mount, Skywatcher ED50 Guide Scope and Altair Astro ASI130mm camera, PHD2 of course. The sky was nice and clear with low light pollution, as around 5 miles from major town. I do not take darks or flats or use Deep Sky Stacker, and I do not use filters, plus the camera has not been modified, so I am always delighted with the results I get from my set-up, as I have a deep level of respect for the hard work that most Astrophotographers go through to get the incredible images that we see here in Stargazers. I have read that some people believe that the Sony Alpha cameras have a tendency to 'eat the stars' and not show everything captured, to be honest, I always used a Canon 60Da for many years for my astrophotography, until one day I though, what if my Sony A7Rii could be used, the first time I did this I released that it was time to sell the Canon 60Da, the 'Remote' (free) Sony software is almost as good as BackYardEOS, but the cameras are a decade apart in performance, the noise levels on the Sony are at least 4 maybe even 5 stops better than the Canon, that is the Sony A7Rii at 3200 iso equal to the Canon 60Da at 200 iso, so at 800 iso it is just so impressive. As you can see from the picture only 12 frames, stacked in Photoshop (Mean). Open to comments and welcome a discussion/debate, thanks Jamie

  18. This always seems to be my "go-to" nebula when I am trying to knock the rust off the gear and get back into imaging and processing mode. This is my first time combining Ha and OIII data using the QSI wsg-8 and first time using OAG. It only took troubleshooting the Gemini-2 (new FW) and getting the Gemini.net ASCOM driver to behave with the SkyX but here it is for this year...

    Dumbbell Nebula

    From the album: Astro Collection

    Love this little nebula, always a joy to look at and always a frustration to photograph as it never seems to go well, with either gear failure or weather getting in the way every time I try!
  20. Conditions have been very poor down in Sydney for the last month (rain, clouds or 'darn' moon every night ) so no new images but at least I have plenty of time for lots of reprocessing ... This one was captured back at the beginning of the year and I'm still playing with it. Here I have been trying to get to grips with the HDR composition function in PixInsight. It is built up from four sets of around 20 images each at 4sec, 8sec, 30sec and 120sec all at ISO800 with my unmodified Nikon D5300. And this is the previous attempt. I think I prefer the composition, colours and contrast of the new version.

  22. A couple of weeks ago i aimed my new lens at M81+M82 and had around 30 minutes of imaging time before sunrise started to effect subs. I wan not expecting much, i just wanted to test the lens. Tonight is going to be the clearest and conditions we have had here in a while now and i will be re-visiting the duo. Has anybody got any tips on how to pick up some of that flux nebula that dominates this region? I will be using a Canon 1100D and a EF200L. I have seen a fantastic image of this area with this lens but it totaled in at around 17 hours worth of exposure. Is that what i need, plenty of hours? A high ISO? Longer subs? Or do i need a better camera? Any help would be great! Cheers

    NGC 7635 - The Bubble

    Hi all, Last November I imaged the Bubble on a few occations with my Meade LX200-ACF and Nikon D7000 on SW HEQ5 Pro, guided with a standalone Nexguider. I managed some 10 hours under pretty good skies, plus 2 hours with H-alpha filter from my small town backyard. So almost 12 hours together (after rejecting every sub with just the slightest defect like non-circular or diffuse small stars). Registering (aligning) was done in Registar, and stacking & processing in PS. I also used the Straton software that removes (most of) the stars, after initial stretching, then I put them back using the "lighten" blending mode. C & C most welcome Ragnar
