  1. After a few months hiatus, weather, work and holiday, I finally got back into imaging mode last Sunday night into early hours - it was a cracking night for astronomy ,cold, clear and dry. I am still using my Samyang 135mm paired with ASI1600MC - its a compelling combination as it is a very light combo and the camera sensitivity allows me to use my AZ-EQ6 mount unguided with 30s or 60s subs. So I took 60 x 60s subs in Ha(7nm), Baader, I used my flat,dark and bias from last session as nothing had changed in the setup (its in a obsy) and DSS stacked 54 of them This is 54minutes capture

  2. Finally managed to get started with my imaging againg. This is the first image of the season for me. 57*5 minutes on the Cocoon Nebula using my modded EOS 550D and Skywatcher 150-PDS. Now for the season is my garden pier. Seems stable enough Tried to keep the editing on the shy side to keep a more subtle look than what I could have done.

  3. Smashing night last night ey? No moon, and a perfect sky - just right for grabbing OIII. So I managed to get in three 2hr panels - enough to put colour into the image. And for a change I've gone for a bit of star colour as well being as it is not a cannistra process image (though I might try one of those later this week). Ideally, I'd like to take the Ha luminance up to 8 hours per panel in order to beat down the noise a bit more for the pixel peepers - but for now 6 hours per panel in Ha will be enough to get the general gist of what the image is about. Tons of layer masks went int

  4. I set off well wrapped up wondering if this would be my last session without a building to warm up in until late March. I had planned well and was ready on a clear and crisp evening. Firstly, I wanted to see if I could see M30 in Capricorn for the first time. It's pretty low and it would be my last chance before next Autumn. Unfortunately the sky was too bright down there so it was a no go. Then to the Trapezium galaxy- M33. I was pretty confident and tried first with binoculars (unsuccessfully) and then with the scope (unsuccessfully). Some clouds started moving about so I moved to Arie

  7. Hi again! Last time I imaged IC5070 for approx 3 hours, then as Orion rose up I decide to use up the last of the clear skies imaging B33/NGC2024. 15 x 600s at ISO1600 with Canon 1000d, ED80 FFx0.85, darks and bias. Looking any advise on detail etc, how does guiding look, focus, etc. I'd like to try to progress so feedback welcome. It is still noisy, so definitely need more subs. I've also lost the plot somewhere with it somewhere during processing as there is artefacts all over the show! Thanks in advance Adam.

  8. I went out on Monday morning with the intention of capturing the Venus / Jupiter conjunction ; just a simple prime focus image with the DSLR. As they were less than a third of a degree apart, they would sit nicely in my refractor. I went out early at 06:45, but had forgotten the clocks had gone back a couple of weeks ago : it was no longer dark and morning twilight was rapidly advancing. So i quickly set the mount up, and went into my shed to get my refractor. Uh-oh...its not there. Doh, i realised i'd left it in my garage overnight after making a few adjustments. In my 20

  9. I got hooked on clusters last full moon and found this. A double cluster to rival the Perseo example. In anticipation of galaxy season and so as to get practise at long focal lengths I did 2 shots; 750mm-f5 and 1200mm-f8. A lot of the smaller clusters are tiny at short focal lengths. As usual, the colour sent me crazy. I think in this case, I'm missing blue. All comments most welcome. 700d: 20x120s and 20x180s

  11. The sky cleared right up tonight and a nice relaxing sky cruise was had, no difficult targets were chosen. Sometimes looking at the same object(s) over and over helps certain features stand out and tonight a really nice star cluster, NGC 6997 grabbed my attention every time the 15" dob was swung on the North American nebula. The UHC gave a fantastic view of this cluster buried in the grey glow of the nebula riveting my attention. Thinking things were pretty good sky wise I popped up to the Scorpion and one of the Claws was contrasted nicely and the Bubble nebula was "bright" with a bit of smal

  13. This year has been the most fun I've had stargazing (only been 4 years mind!). Joining a local astro club, meeting more experienced observers and enjoying some really dark skies have shown me a whole new side to the hobby. My first scope was a Celestron 6se and although I did have some decent times with it, I found the goto a bit challenging to get working well. So I moved onto alt az slo mo mounts such as the porta 2 with the relatively small tv85 and Tak fc100df. I got on better with these and began to learn the skies and be able to star hop to new objects reasonably easy. The

  14. Probably not the best target for my unmodded 550D and with half the moon lit up, but i wanted to give it a go anyway. Image is 42x 600s exposures at ISO 800 with the Explorer 200. Stacked in DSS and processed in PS. I used the CLS filter when imaging this and it helped a lot on the light pollution from the nearby city, but it did affect the star color quite a bit. 7 hours of exposure did help a bit bringing out the nebula and i'm quite happy with it. It's still a bit noisy and not very deep though, but i'm sure i'll get back to it at a later point with a better/modded camera and no

  16. Have now added 3 hours of OIII from last night to my 5 hours of Ha, all 20 min subs, ISO800. Equipment as per my signature block. I am not finished with this yet, but could not resist posting it to get opinions on it as a work in progress. Not sure my pallet is very conventional but I like it, hopefully not pushed it too far as I often tend to do. This was my first time imaging this target and I was a little shocked by how faint the OIII signal was. Edit: So I got my flats working and toned the whole thing down a little. Also decided I like it better standing upright.

  18. Yep, that's exactly my experience too. I have 4,5,6,7,8,9,10mm for planets. For other targets I'm happy with 70% jumps but tweaking the image on planets is a very different matter. Though of course since the planets are now on holiday in Australia for the foreseeable future, it's all somehwat moot

I can't believe that it is over 12 months that i was given the go-ahead to sort out a observatory\shed for my nocturnal activity, where does the time go Anyway i have finally made a start, not the best time of year for doing it i know but hey ho! I did have a 9x7 shed already in the garden, that however has now gone,upon close examination it really was not suitable, This does mean though that all my equipment is currently in storage, My pier is already concreted in place so i am having to work around this for siting new observatory\shed, I did get some quotes for having th

  22. Not quite a review - yet - but more of a just-after-unboxing session. Having ordered a Borg 71FL from our friends at FLO, I was gleefully contemplating using it in tandem with my TV-60. Having passed on both the Ercole and the Ercole Mini, both having honorably served but having been superseded by the Losmandy AZ8, I was left with the AZ8 as the only option which is somewhat less mobile (I know of and respect those of you who have no qualms hauling around much heavier, bulkier mounts, but just bear with me). So, as perhaps something of an implulse buy, the Castor was ordered directly from

  23. My only clear night for ages was on the 12th November. The wind was very strong and I had neighbours insecurity lights going off all evening. Guiding was being upset by the wind and I lost a lot of subs but managed to get this. Any comments are welcome as usual and thanks for looking. Taken with ED80 and Canon 750d (unmodded). 28 lights of 300 secs at 1600 iso and processed in APP with some input of PI and PSP. Peter

  24. ....what all the fuss is about. Last night I was up in the Brecon Beacons again taking advantage of the clear skies and last quarter late rising moon. When I was there two weeks ago, I failed to find the Helix Nebula in the constellation Aquarius. I had gone to it quite late in my session on that occasion and lost a battle to observe it with a tree low down in the south west. Tonight I went to it early, star hopping my way from Skat (δ Aqr) via 66/68 Aqr and finally υ Aqr from where it is very close. First I put in my UHC filter and at 59x magnification using my 17.3mm eyepiece a large circula

  25. Captured this over the course of several nights in October. Can't say as I enjoyed imaging it much, it's an untidy nebula and an even untidier image! Scope: Tak FSQ 106 Camera: QSI 532 wsg Filters: Ha and OIII Baader 7nm Ha 22x30 mins OIII 13x30 mins Captured, calibrated and combined with Maxim and processed in PS Ha mapped to green and OIII red and blue It was a bit of a slog to process and in the end I think it looks best with quite muted colour. I think it should be called the Pavement Pizza Nebula!

  26. Cracking work Eric. I was going to comment that it was too large to be Uranus, but you beat me to it and edited that it was Capella. Loving your flame, horsehead and running man nebula images. Great capture of the Venus and Jupiter conjunction Ben. I'd completely forgotten about it until Terry texted me at 7am to ask what the bright "stars" were. Managed to dash out with the DSLR and grab a couple of quick images before they were lost to the dawn. It was a beautiful sight and a gorgeous sunrise

  27. Evening everyone I managed to grab what could have been my best run of the year last night. After a minor equipment issue (the arduino board running my focuser died) I managed to get a good few hours of imaging done. M33 - 12x300s @ ISO800 Iris Nebula - 15x300s @ ISO800 Elephants Trunk Nebula - 25x30s @ ISO800 These are far from perfect and I will be reprocessing these once I finally save enough for PI, I also intend to add more data to these as well

  28. On Friday my third used Canon 60D arrived from Amazon and Saturday night the sky cleared and I finally got my triple rig together consisting of a 60D on a Samyang 135 f/2, a 60D on a Canon 300mm f/4 and a 60Da (the factory modded version of 60D) sitting on my ES 127 ED apo, all on an EQ8 mount in my obsy. I went for two targets, starting shooting at NGC7000 around 7 pm and then at midnight it was getting too low so I shifted to IC348. I was of course asking for triple trouble but I got some useful data to process. All was supposed to be at ISO1600 but after a meridian flip at 01.30 I forg

  29. Well there have been some great threads on here, loving the one regarding the neatest/untidiest workstation. Many people are really OCD about tidying up their cables for imaging. I on the other hand couldn't give a stuff as I am always derigging for astro camps and changing kit around I'd be forever unravelling cable ties. So I just let it all hang out, but just make sure nothing is snagging. I wonder who could beat me. This is not the best shot as I didn't take one specially for this thread. But this is what I get with a dual rig. Cables just tied back initially.

Hi I am still about just not done any imaging So I though I would have a go at narrow band imaging ( my first ) This is the Heart nebula in the std hubble pallet ( SHO ) and the first image with my new Tak 106 there is about 3hrs in 10min subs in each channel and off course was processed in Pixinsight , could be better but I am happy with it for a first go Please see here for full res version http://www.harrysastroshed.com/image html/nebula HTML/heartnarrow.html Regards harry

  32. Well it was a good night, weather-wise, last night (12-Nov-2017) in this part of Oxfordshire. Cool (3 degrees) but amazingly dry, really (85%.) And so, for once, everything wasn't covered in dew by the end of the night. After an earlier debacle with coma-corrector spacing, I've shaved off a further 0.5mm to try and tweak it a bit better, but I've also (for my sins) started a trial period with PI. I've so far eschewed this box of tools in favour of simpler, and some home-grown, things. But I'm interested in finding out more about what so many people use... even if only to understand th

  33. I'm still a traditionalist and like a good star chart, although some software out there like sky safari is very good. One of the mob uses a nexus with his phone and it is really good, whilst another uses the ipad as a reference. NGC 7331 is a wonderful galaxy in it's own right but managing to pull even a couple of the members of the quintet out will be challenging but very satisfying. The quintet is also known as Hickson 92 and there are quite a few others you may like to try such as Seyferts sextet, the box and Copelands septet to name a few. Look them up they also fall into t

  35. Boring? Start the run then wondering if the neighbour is going to put the rubbish out and set off his backyard floodlight, will the USB connection drop out? Will the cloud roll in? Will the guide scope dew up? Will the mount throw a wobbly? Will an aircraft or satellite wander into the field of view? Will the run finish before the scope starts to image the roof of the house, trees etc or Mrs Sitech cooly declares “mount approaching meridian limit”? Trust me, there is never a dull moment....

  38. That's where I think a smart phone or tablet with SkySafari can be really useful. You can easily fine tune the display to a certain field of view, orientation and with the limiting magnitude of the stars visible set to match what you are seeing. Makes it much easier to focus in on the particular target. In this instance shown there is a 1 degree fov and stars down to mag 14.0, correct image and the Quintet centre of field.

  41. Hi everybody. As the title says this is a first light with my new setup. Data gathered last night. Usually when i get a new bit of gear it takes some time to get everything working as i would like, but this just seemed to work from the start. No software or hardware issues. In fact the only issue i had was a lack of thumb screws on the rotators which was sorted with the thumb screws from a couple of serial cables. Ngc 1333 is a reflection nebula in the constellation Perseus. At about 1,000 light years from earth the dusty region extends from the California nebula all the way to th

  42. Under the skies you had some of Stephans Quintet will be visible in your scope. Try the 8mm Delos and the 5mm XW, swinging the scope a bit to pick them up. They are faint...and can pop in and out of view, depending on the telescope. Pickerings Wisp is big and likes a wide TFOV- I use a Lunt 20mm HDC these days and it works really well and will illuminate your eye a bit better than the 17.3 Delos. Great report BTW!

  44. Sounds easier than my experience. I thought I'd found it through the finder quite easily with a quick star hop. However I then decided it didn't look planet like enough - not sure what I was expecting, it didn't look very planety in kielder either. I then proceeded to star hop to it twice via different routes. This turned into 20mins of checking and double checking Stellerium on my upside phone (I don't have a raci so this makes it easier) I then pushed the mag to check I got a disk (it seemed very wibbly last night which made it difficult to decide if i was focussed when on the higher mags).

  46. @ollypenrice @wimvb @Rico @Philip R Good evening, Well, I said I would report back with some results after some tampering. From all of your feedback, the prime suspect, and easiest to amend to start off with was omitting the focal reducer from the light train. So, I went through, every thing the same as I did before as best I could. Same number of flats/bias/light/darks and used the same processing and stacking routines in PixInsight as I did before. I used M27 as a target too, so I could get as good a comparison as possible. I'm really pleased that in this instant, the halo

  48. BTW a somewhat quicker method is to visit someone who have some years of practice already. I remember my first visit to a certain Olly Penrice, as he chucked my sub par data of the night into his PC and like a Jedi pulled out colour and detail beyond what I could comprehend. I will never reach his level, but the kick start this visit provided was price less for an amateur like me. /Jesper
