  1. Forecast on CO for tonight wasn't great, but when I got home from visiting my folks, the sky was clear so I took a chance and set up the ED120 on the AZ Pro. Tonight was the first time that I'd used the ED120 on the AZ Pro and I was pleased to find that the mount was perfectly happy with it mounted, though it took a couple of seconds to settle after focusing. After leaving the mount to do its auto setup and doing a 1 star align on Rigel I was ready to go and connected the phone to the wifi, fired up SkySafari and found an observing list for objects in Orion and off I went. I st

  2. Hello, This nebula has many numbers and names - Westerhout 5, Sharpless 2-199, LBN 667, IC 1848, Soul Nebula or Embryo Nebula. It is a big object that gives spectacular show of light, colors and shapes, no matter what scope and camera are used. The emissions in various wavelengths combined with dark nebulae, pillars and bubbles of creation are almost hypnotizing at least for me The pillars which are so many here and are very beautiful, but the small bubbles floating in the blue light are like gems. The processing is pretty conservative – no hard push and no noise reduction in order to pr

  3. I’ve finally got the hang of my 16 inch Skyvision goto dob (been a bit of a journey with some initial disappointment but now it’s working really well). A rare clear sky last night so I couldn’t resist seeing what the dob and night vision monoculars could do on the horse head. Here is a phone pic of the eyepiece views (the actual live view was virtually identical to this). The 55mm plossl does show astigmatism with my f4 dob but visually I don’t really notice. Quite intoxicating to observe... A great end to a very successful year of observing for me. PS I also looked at some

  5. Dec 27 offered a much different level of transparency than today with the 18" of snow that fell (is falling). The 27'th was a super night of dark transparent skies so out went the 24". I finally received the 8mm Delos and also a Baader pushfix and the TV in travel adapter. Both work very well. I had a good view of NGC 891 a while back so I figured to try again with it at zenith. This galaxy gives up a massive central lane and the 17.3 Delos gives a great bright view in the dob, with the central large "core" showing well. As the mag was upped a truly unique view appeared and with the 8 Del

  8. Not sure why but this image has given me more trouble than most. There is a balance between brightness and subtlety in the star field saturation and brightness that has eluded me through countless versions. I processed for days before I realized my screen brightness was set at 100%--not good! I then realized I had forgotten to insert the Lum! I think I have reached a point where I can be content. I prefer RGB nebula, but the starfield was too dark without the lum. As such, the nebulae in this image are mostly RGB, while the starfield and surrounding clouds are LRGB. I think the image

  9. Hi everyone, I just wanted to share my latest image; which is a narrowband, Hubble palette (SHO) composite of the Lion Nebula (Sh2-132) in Cepheus. I acquired this image using my Takahashi FSQ-85EDX, EQ6-R Pro mount and Atik 383L. Guiding was done using an Altair GPCAM2 AR0130 mono camera and TS Optics 2" off-axis guider. The total exposure time was around 14 hours and processing was carried out in PixInsight, Photoshop and Lightroom. More details about the image can be found here: https://astrob.in/zw2517/0/. Thanks for looking. Any feedback would be welcomed. Ch

  10. I'll try to throttle the "Oh it's nothing really", but it really WAS supposed to just be a test of my mount's repairs. Pleased to report that between the repairs and running PHD2's Guiding Assistant, I was guiding down around 1-1.2" RMS in RA and 0.8" in DEC, which sadly is WAY better than I was getting before. Hope I can get better still. But since I had to point it at something, I pointed it at the Bubble and the M52 cluster. This is maybe a 50% crop of the FOV from the Stellarvue at 368mm and the 183; plate solving was cranky on the second night when I was collecting OIII data so there

  11. Further progress made over the festive season, the circular rack made up of 6 lengths joined together, has been installed using adjustable brackets so that it can be made reasonably level and circular so that the drive motor does not have to be spring loaded. The rack sections were purchased from Poland as a one off on eBay, but I have had a quick look on the net, a lot of powered gate fabricators can supply something very similar, around £22 for a metre length. The motor and drive gear is almost complete, a rotary encoder has been fitted, to enable precise positioning of the dome apertur

  13. Out to catch the Moon again late afternoon. There was a strikingly red and hazy sky after sunset,. It made the sky look rather strange, almost like a painting. Took some pics with the SW80ED and Olympus camera. All pics taken between 4.16 and 4.25 pm. Moon 3.47 days old and 12.1% Illuminated.

Of course also review the optical performance, to the best of my ability, when this damn lid of clouds that has been covering the south of Sweden, clears up.

  16. Another dataset from 18m ago using @Petergoodhew 's rig when it was at ICA. This is 52x600s luminance and 20x300s for each of the RGB channels. The outer ring was barely above the noise level in single L subs, hence the volume. which definitely helped in processing. Taken with a 1200/152 TMB and QSI6120. Thanks for looking.

  19. Having recently improved the collimation on my Tal100RS (mainly by blind fumbling) I thought I’d make use of clear skies to test the scope on some doubles. Having waited for it to cool I popped in the 5mm BST giving 200x and slewed to a brightish star - the results looked promising, with some nice even diffraction rings which were were slightly broken by the average to good seeing conditions. Buoyed by this result, I slewed to the Trapezium. A beautiful sight as always, the E component was immediately visible but the F was hiding from me, despite looking for a good 20 minutes. Next was Rige

  20. Hi all, after several weeks of rain, cloud, circumstances I'd thought I'd have a good chance of imaging the sun today. Not so, waited patiently while I expected the sun to pass the trees on my horizon only to find it setting before it cleared all obstacles. Last time I imaged from my new home was several weeks ago and the sun cleared everything by 2pm. Looks like I'll have to wait to Feb/March unless I travel. Here is my attempt today, quite disappointed. +.

  21. I'm a amateur astronomer with a special interest in spectroscopy. I'm also the designer of the 3d printed 'LOWSPEC' spectrometer. At the moment I'm working on the new manual for the new version of the LOWSPEC which will have a new grating holder that can easily be swapped with a different grating without opening the instrument. I hope to upload the files just before the new year. Regards, Paul Gerlach

  24. Welcome to Astronomy and this very friendly and helpful forum. I'd spend a little time using your new scope and finding your way around the skies before trying to start astrophotography, it's quite a big learning curve needing rather expensive equipment. Things to enjoy at the moment. The planets are fairly low, but depending on you horizons, Venus is currently to the right of the Moon in the twilight sky. Both are worth looking at, Venus will not appear completely round as it has phases like the Moon. The Moon will be bigger in the next few days and is best viewed at around ha

  25. It's a lovely day out there today, so I put the mount out to have a bit of a solar session, and to check whether I could align the scopes easily. The setup looks fabulous I must say, and I love the Planet tripod. I had a play around for a while, loosening each saddle and tweaking the position to align the views vertically. It is a little fiddly but I've got it pretty close now, a bit more work needed to get them exact though. Despite the low altitude and poor seeing, I had some good views, one quite active prom to look at which showed changes over a relatively short period. White lig

  26. Not had a good session with my 12" Dob for many weeks so with a clear sky forecast I decided to have a session. To be honest the sky was not the best but I felt I needed to have a go with certain objects. I started with Vesta having never observed it before. Vesta is high in Cetus fairly close to 87 Cetus. Cross referenced to Stellarium and found it - need to check if it moves to confirm I was observing Vesta. Now a few DSOs - started with M74 - not the easiest object but very clear in the 12" Dob. Moved down to M77 and also took in NGC1055 but this object was difficult and I could

  28. Compared to some of the previous posts, the history of my telescopes is rather simple and short! My first telescope was a Celestron 114mm f8 bought in 1998. I observed with that instrument for about 4 years. Due to moving to a new house, then university, then moving to a new country, I didn't observe for years, until early 2014. At the time I visited an observatory in Northumberland and regain interest in astronomy. I decided to get a 15x70 bins first and then a TV-60. The latter served me for a few years until I decided to get a Tak 100. This year, i finally bought a 12" dobson. In

  29. This thread brings back some happy memories. As I have thought about my own history, it seems I don't like getting rid of telescopes! C8 - To see Comet Halley and fulfill a childhood dream of having a telescope. 8" Homemade Dob - Fulfilling another childhood dream of grinding a mirror and building a telescope. Still use this one. Sold C8. Sad to see it go, but the 8" Dob has better optics. 20" f/5 Dob - Built by Tectron (USA) and eventually rebuilt by me. Excellent views but ultimately too heavy and required a ladder (which my knees did not like). Fujinon 16x70 bi

  30. My Arp journey began back in February 2019. I hoped to be able to complete the challenge using EAA in a year. Last night (actually this morning) I visited the final few. There are 8 of them I cannot see from my site in GB. I plan to re-visit a few and no doubt when others post their results I will be prompted to take another look. Some of my results have been rubbish. It has been a wonderful journey. What next. I quite fancy the Thin Flat galaxies. About 140 are within reach of my site. Dare I start the VV galaxies - well over a thousand are doable for me. Thanks to Martin for the inspira

  31. The annual Quadrantid Meteor Shower may already be underway, and is expected to peak during the night of 2020 JAN 03-04. Its radiant is in the no longer official constellation Quadrans Muralis, which is now part of Boötes. That is the direction toward which the meteor tails point, but the meteors are equally likely to appear anywhere in your sky. It is conjectured that the Quadrantids are debris from the asteroid 2003 EH1, which in turn may have been a castoff from comet C/1490 Y1. The peak rate of the Quadrantids can be as great as the normally most prolific annual showers at possibly a

  32. The Meade 14 inch LX200, which was kindly bequeathed to us by the late Alan Longstaff, fell foul of the belated 'millenium bug' which has affected lots of GPS-related devices. Before the bug it was sometimes spot on, sometimes not, for setting up the alignment and then 'going-to' objects. Post bug I've just been putting in the time and date and doing a two star alignment. This is so much better than the GPS-based palaver! It takes half as long and gives reliable go-to every time. My previous LX200 10 inch was equally reliable in two-star align mode.

It seems reasonably accurate based on my observing experience and others in the society tended to agree. The darkness of your skies and your observing experience will affect how much you can see.

Here is a good article on that subject: https://www.skyandtelescope.com/astronomy-resources/transparency-and-atmospheric-extinction/ You need to account your altitude above sea level, position of the star but also AOD - aerosol optical depth which is general measure of atmospheric transparency. good AOD forecast can be seen on Copernicus https://atmosphere.copernicus.eu/charts/cams/aerosol-forecasts?facets=undefined&time=2019123000,3,2019123003&projection=classical_global&layer_name=composition_aod550 AOD has impact on light pollution levels as well - but I

He does not like stopping Weather is bad all over from what I have read. We will just have to suck it and see what happens. I hope regular attendees are not put off from booking up at the spring star camp, because as you will appreciate things can change quite quickly and the site dries out fast.

  42. Thanks Stu, the mist and dew came in later here but very suddenly. I came back from my folks yesterday but was determined to get out last night and am glad I made the effort. However, the very strong coffee at 21:00 before I went out meant that I was still trying to sleep at 03:00. Lesson learned. Thanks Mark, I don't recall ever seeing it in the 8" though it is probably a case that I was less aware of it then as I was still starting out. When the dew came in last night it was very quick and very heavy and finding everything suddenly dripping was what prompted me to call it a ni

  43. My interest in all things astro began long before any telescope arrived on the scene. As a small child I was fascinated by programs like Fireball XL5. I remember being woken by my dad and standing in my little striped pyjamas in front of a blazing coal fire, watching the moon landing in 1969 in black & white. I was 7years old. Around that time I remember my first, lone, astro expedition, where after I'd noticed a crescent moon in the south west while looking from my bedroom window, I thought I'd walk down the road until I saw the moon from beneath rather than from the side. It seemed logic

  45. Who the hell comes up with these crackpot projects anyway? The space surrounding Earth is crammed with enough junk without throwing anymore up there. The main aim in my opinion, is to make money for those responsible, and not so much to improve communication planet wide. I'm sure technology in time, will improve sufficiently in order to achieve that goal without the need to litter the night skies with hundreds of pesky fireflies. Is there not a world governing body existing to veto this madness? Ron.

  47. 1) My first scope was a Celestron 6SE, purchased in 2012 after my childhood interest in astronomy had been rekindled after getting some binoculars for a Christmas present. 2) After that (and a fair bit of research on SGL) I soon (in early 2013) purchased a TV85 and got hooked on refractors. I still have the TV85. 3) The 6SE was soon exchanged for a skywatcher Equinox 120 but that got sold quickly once I got... 4) A Tak FC100DF in early 2014 when they were still a pretty unknown scope. I kept this lovely scope until just a few months ago when I sold it to a fellow Walton Austro c

  48. Clouds prevented imaging last night but there is hope for tonight. Meanwhile I have improved (I think) the processing of my first image from here, the Large Magellanic Cloud. I used Olly's @ollypenricetrick to get more Ha visible by using Selective Color in PS, chosing red, and turning cyan all the way down. I al oturned down cyan for the magentas. Both adjustments made quite a difference. Then I brought out more of the fainter parts of the galaxiy using curves, which made the Tarantula nebula more clearly attached to the cloud.

  49. My wife is pretty tolerant of me. I keep 4 scopes in the house, one of which is an assembled 15" truss dob However, there have been a few comments about the amount of kit I have, and it seems like I should compromise a bit. I won't store my 10" in the shed - the mirrors will quickly deteriorate I'd say, and no doubt the structure will accidentally get damaged. I've thought about selling, but just don't like the idea of haggling a price that might leave me feeling empty inside. So I've come around to the idea of just giving it to a good home.
