  1. I decided to try to see if I could capture data from 2 cameras simultaneously. I did try this once before but got flexure in the 2nd camera, so this time I set up using the side by side bar and a more substantially mounted finderguider. Ultimate plan is to image with both Atik cameras, one with Ha and the other doing either RGB or Oiii/Sii. However I wanted to see if it would even work before purchasing another Ha filter (can't remove from my EFW as it's the unmounted type). There was obviously a FOV discrepancy but it won;t be so bad when I use the 2 Atik cameras. It's ages since I im

  2. Since I've had my new 16" I've been glued to the Trapezium and M42, I always think I'll have a quick look and then I can't tear myself away from it. So a few weeks ago I had a clear spell with no moon so decided to sketch the trapezium. It didn't seem right without the nebula so I had a go at this as well, but I'd never drawn a nebula before. I'm painfully slow at sketching so after a while the clouds came in and there were quite a few stars, mostly near the edge, that I'd missed. I really enjoyed doing it, the scene was changeable as I plotted the stars and the incoming cloud near the end cre

  3. It feels like a great target for a beginner, M31 pretty much fills the field of view on my scope and I see promising results as soon as the subs start coming in. I've been at this new hobby for a whole 8 or so weeks now, which I guess equates to a total of around 6 or 7 nights, the rest of the time has been hampered by what seems like one continuous blanket of cloud. I'm fairly confident setting the kit up and the tech side of things (although just started guiding after an arduous 2.5 hrs initial setup) but when it comes to processing my images there always seems to be a standout niggle and it

  4. Bit of an experiment to see if I could get the full sun on one of the cams I have. This ended up being the Atik 314 with a 2x barlow with the top removed (so ~1.7x) as the ASI was too small and showed newton rings and the DMK was way too small (which I knew already). As you can see, it only just fits. Happy enough with how it came out, so is what I will use on 20th, clouds allowing!! 8 fits files stacked and processed in R6 then PS to bring out the proms a little more.

  5. Decided to have a try at another mosaic yesterday and took 25 panels but used 23. Not sure what I did yesterday but I mucked processing up and this morning looked at it again and it is much better.

  6. Last night turned out to be an unexpectedly clear night, so whilst Dave was (unsuccessfully!) trying to sort out the vignetting issues on the FSQ106, I opened up the other observatory and imaged this. It is a stack of 10 x 15 minutes in ha, taken with the Tak FSQ85 + reducer and Atik 460EX, processed in Pixinsight. Just hoping the skies are kind to us so we can grab the colour data before the object disappears till the autumn! Dave and Zoe

  7. Hi, The title is not strictly true, I only got half the sun in Ha for a 12 pane mosaic (cloud and going out stopped play), but did get the whole of the sun in one go with a focal reducer. Sadly my field isn't very flat with a focal reducer so the full disc isn't very even. Still good to get something from this morning's effort even if the gap was small. Robin All pics Lunt 60 DS.

  8. Hi, Taken quickly between the clouds passing and eventually arriving at 11pm. This target is getting very low for me even at 9 pm. A lot went wrong as well so I had to change the camera and then PHD wouldn't play. The image is very noisy as I had to dump 4 subs as the target was well low and in the heavy LP zone, the stars a bit funny too because of the strong gusts tonight. 9 X 600s subs with Bias and Flats stacked in DSS. WO Star 71, Atik 383L+, Baader 7nm Ha Filter on HEQ5 Pro. Processed in PI and tweaked in PS. Thanks for looking. Regards, A.G

  9. Not much chance to do Lunar as trying to practice my planetary imaging, however was out on the 4th, and after filling up the hard drive twice with individual jupiter channels, I decided to head back to more familiar territory. caught Schroteri. not the best time to get it, but was quite pleased with it. usual set-up Edge800HD, AVX, ZWO120mm-s, IR pass. Quite interested to see the LROC height difference, and the view of the Cobra head from another perceptive. I have exaggerated the height difference by x2. Thanks for looking

Skywatcher 150p goto Nikon 3200 dslr 2x barlow lens 1/100sec ISO 200 Love your input on where I went wrong/improve............ But regardless I'm pleased, Enjoyed myself....looking forward to getting out more!!!!

  11. I forgot to add I also took some foucault images. I had the Knife edge on a slant as I attached it to the tester with blu tac. Think I must've had a big smudge on the mirror too? I took these on the 13/02 And these on the 21/02 Quite difficut to get decent image's and to interpretate as to what's going on but the first set show the edge quite well Damian

  12. Taken in 2 sessions on Feb 26th & March 4th a total of 80 images encompassing the full rotation of Jupiter. Unfortunately some long cloud interruptions spoiled the 2nd half causing 1 hour breaks and the seeing at times was very poor.

  13. with all the images I shot a lot were for the bin conditions were far from great, a lot of random panels were blurry, on the screen you could see the sun wobble then stabilize quite often, enough excuses heres the images 'white light 7/3/15 by sooot22, on Flickr' 'sun 7/3/15 by sooot22, on Flickr' 'sun invert 7/3/15 by sooot22, on Flickr'

  14. Thought I would share this. NGC329 , the Pendant nebula, is found n Carina, in the southern most corner of the Gum 30, hence the nebulosity. As objects go, it gets picked up every so often because the cluster is around 10 million years old, but has a combination of both young blue (sadly bludgeoned to death in processing) along with the odd M type star in orange, so it becomes interesting from the point of view of Cluster evolution. ESA did a thing on this last year with some interesting publicity images coming out. Details This is HaRGB, with Ha at 20 mins subs (4 hours) and RGB at 5 mins

  15. Hi All, thanks to some advice from my uncle, I think I have solved the tight spots people are finding in either or both axis of their EQ6/NEQ6 mounts with the clutch off. I have not known for a year now if my scope to counterweight balance was good enough because of the two tight spots I had on the RA when horizontal. And it has nothing to do with burghs or rough spots in the housings. It is the taper bearing in each axis. My uncle told me that as a long time mechanic the most precise part of putting the front drive of a car together was the taper bearing. It could take hours

  17. I've posted a few general photos of my Istar 150mm F/12 achromat refractor a while back but while I was giving the scope a gentle clean (not the optics !) I thought I'd take some pics of some of the details of it's construction for anyone who might be interested in this sort of instrument. It's a very well engineered scope to my eyes, in a completely different league to my Skywatcher ED120 and Orion Optics 12" dobsonian. It's manufacturered partly in the Czech Republic, Austria and the USA with the objective lens being made in Asia but assembled, tested and installed in the scope in the USA. T

Done with the Canon EF 200 @ f/4 (aperture stopper to avoid spikes) and Moravian G2-8300FW. Ha 23x900s, and 11x300s for R, G and B.

  19. Couldn't resist having a go at catching this..... Comet Lovejoy near to the ET (or Owl) cluster. Unfortunately in my rush to get an few image before the moon lit up the sky I didn't get the focus as good as I would have liked, and the breezy conditions meant my setup was getting buffeted a bit. I might have to have another go at this target later this week if the weather permits. [The image is a single 60s exposure (Canon 650D; f/5.6; ISO1600; 400mm equiv FL) on a Star Adventurer mount.]

  20. After a long wait for the weather to be kind I finally manage to test my Bresser Messie 152s and my autofocuser adaptation (http://stargazerslounge.com/topic/237997-bresser-messier-152r-refractor-auto-focuser/). I used my trusty CG5-GT mount, which some say it's at the limit of its capabilities with 10kg on top. Last night was not the best in terms of seeing but good enough for a short spin. A bit windy and in spite of Saturday 07 March hitting 16.5 Celsius were I live it did get cold by the time I went back in. The targets I chose for this first spin were Polaris, M42 and Jupiter, all using

  26. Use steel wheels on steel rail. 12 per side is way too many. You just need two per side, unless your roof is massive. These are the wheels to use (they can be recessed into the frame) : And this is the track: Steel on steel will give a very low friction solution...literally one finger to move. And they are self-centring. Rubber wheel, wheels that run inside tracks, multiple sets of wheels will give issues with centring, wheel flattening and friction.

  30. Love my super Tak. Holds focus perfect at any angle and is sharp wide open. The adapter ring has a flange that pushes the aperture pin in when you thread it on. Fotodiox makes some of the better ones. Just fyi. Enjoy!

  35. Hello, Did my first ever image today, after starting this hobby about a month ago. I know it's rubbish, but is only a single 30s capture. I was just excited that all the reading and learning meant that when I finally pressed the shutter button, an image actually appeared. This is the positive start I wanted, and has given me the bug to go forward. Indeed it is a steep learning curve, but at least I know I am now on the right track. Thanks to everyone on here who has help me along the way. Better images to come in the future I'm sure Thanks Alistair

  36. It sounds as if you are looking for permission to spend some money. We can award official permits for astro-spending for just 10% of the intended spend. We are part of the International Astrospend Clearance Committee and can also supply stars for private naming at very competitive rates along with first class real estate on the Moon and Mars. Please don't hesitate to supply your email address so we can bombard you with endless BS. Olly

  37. I have been round this loop a few times. Direct Line assured me that would be but only so long as they are in a locked car or at home. I took this up with them as they are listed on an 'all risks' and the answer was basically small objects like iPhones, Cameras are covered but a large object like a telescope would not be eligible (dont ask - no idea why). A few years back I tried some specialist insurers for out and about at star parties etc and none of them would entertain a scope in a field as an insured risk except at a ludicrous premium. They will insure in your house, in an observatory

  39. The Orion 8" Astrograph Newt is F3.9. The shorter the focal ratio, the more pernickity they are about collimation. Some of the above may apply too, so checking that the spider is well centred and nuts tight, likewise on the secondary adjusters, then it really shouldn't move. I'd also add that adding things to the secondary holder with plastic in them (milk bottle washers, Bob's Knobs, etc) may make collimation easier, but the compliance in the plastic will make them a self fulfilling prophecy - You will need to use them more, because you have them. There is nothing like a good metal to metal c

When I first used the Quark I didn't see much of a difference when changing the heat settings. However, today it has made quite a difference, I have been keeping the positional indicator in the centre but today I moved it backward or left 3 places and it made quite a difference and brought out some excellent detail on both the proms and surface features......When moving it back past the centre and 3 places to the front / right there was a slight degra

  43. So after weeks of frustrations with my mount (as some of you will be aware) last night I managed to get 5 hours of Ha data of M81, M82 and some other smaller galaxies ready for combining with RGB data when the moon runs away again. First time I've ever images a galaxy other than the obligatory picture of M31 with my DSLR. The important thing is star shape. Over the last few weeks with the mount throwing a wobbler, the stars have been very eggy across the image. Not so any more Nothing exciting to really see here, interesting the amount of Ha data in these galaxies though!! Just a very quick s
