    No match for Olly's 400hr piccy but I've been following the progress of Barnard's Star for over 7years - below. It has the highest known stellar proper motion of 10.3"-arc per annum due north. Interest tweaked via Burnham's Cel Hdk [anyone use these now or in the past?] with it 1960 epoch position marked. Data on image with shots from 2008 July 29 and recently 2015 June 18 [main image]. range 6ly age ~9BY mv 9.5 red dwarf = BY Dra type annual PM = 10.3"-arc due north Hope its of interest. Nytecam

    My first post, so be gentle. I am not sure of the convention, do you post one big'un in all its glory, or a couple of tiddlers to give more of a feel for the shoot - anyway, I have gone for the lil’ option I took another 4 photographers up to the iconic Daymark Beacon close to Kingswear. The basic plan was to try to get good views to the south, but be aware of the light pollution of Paignton & Torbay. We arrived on site at 12:30, parking in the carpark and a short walk down the road brings you to the tower. Background - built in 1863 the Daymark is a hollow, octagonal tower built of limestone and rises to 80ft into the air, it was used to mark the entrance to Dartmouth harbour. Conditions were great, the waxing gibbous moon was to the west giving a nice light onto the tower. Milky Way was very prominent, only obscured on the horizon with a small bank of cloud. A couple of ships in the bay added to the view, the Start Point lighthouse was a small problem, but was to the South West. I find wide field astrophotography highly frustrating, using all the tools & apps you can visualise what you want/expect and there is normally a very big reality gap when you get on site. Thankfully last night exceeded expectations, a great night with amazing light. Having 5 photographers at one location at night is always a bit of a trial – but we got there in the end, they had fun & hopefully went away knowing a bit more about the process. All images on my Canon 1Dx, shot on my 15mm f2.8 fisheye, exposures ranged from ISO 3,200 to 12,800, shutter was either 30” or 25” and I did try fiddling with the aperture, most were at either f2.8 or f4 – images de-fished by hand in Photoshop. The Milky Ways have had some work on their structure with the Viveza, Nik Plug-in, plus a final de-noise with Dfine 2 again from Nik. I am more than happy to hear thoughts and suggestions or answer any questions. Some of the shots were compromised by having a field full of light waving newbies, but I am more than happy with the results…

    I'm working towards a HST image and, with a bit of luck with the weather, may have collected enough data by the end of July (fingers crossed!). I processed as I was getting concerned about gradients from the moon and also the limited 'darkness', the results were good enough to post as I haven't posted an image for some weeks - work, life etc - all the normal distractions preventing image capture.

    After my first ever run with saturn here is some photos that I have got from processing a few videos! This is without any tweaking in photoshop and I still have about 10 more videos to look at. I may be able to get more detail yet! I want a bigger image but not sure what to buy that is best for my scope! The images are on average 60% of frames first stacked in as2 and then wavelets in registax. Seeing was not too bad last night but there were a lot of small clouds coming past during recording. Thanks for looking. [emoji92] Astromaster130

    Sorry for the late post I forgot I had these on file so thought I would do them to clear my drive. Sadly this one's on the way out but maybe she will make a journey & survive so we can grab it again. As soon as setting up heavy cloud came in so I waited 90 mins just to get one.

    Two more experimental shots 1) 15 frame stitch 2) 35 frame stitch, however, there is a lot of overlap so probably not as perfect as it sounds. Both have been processed identically so comparison is valid, I think the detail in no.2 is a touch sharper. Shot through very thin high cloud 26/6/2015

    I saw some work other people had been doing in the forum capturing the Elephant's trunk nebula & thought this would be a good target for my RASA. I started the HA capture last night & obtained 27 reasonable subs. The conditions were a bit hazy so I know detail is lost & the light skies don't help but I think the result is encoraging. Let me know what you think. I only have the HA at present. This is 27 4 minutes subs using the 2" Baader fast HA filter & the RASA (Astrodon) LPR Filter. Guiding is done using direct guide on the Paramount/SkyX & the processing is done in Ccdstack & Photoshop. The image looks much better if you open it up full size. I've presented the full field as captured with no cropping.

    Captured out of the front door at 5:45am this morning before work! The usual set up PST/DMK21au618 2,000 frames stacked approx 300 in Registax 6, lightly sharpened in CS2. Should make for some decent proms next week judging on its activity recently, looking forward to next week there should be some new AR's if the proms in the east are anything to go by.

    No offense - as it seems to be a popular design – but opted for the owl’s nest instead. Took nearly a month and half to receive the AVX adapter from Dan’s pier plates – then another week and a half for the machine shop to make and weld the baseplate. Still fighting the weather – seems like rain every other day – and there’s always the 40 hr. a week job to slow you down - but the wheels of progress are slowly beginning to turn. The goal of this pier is stability - with minimal deflection – but also adaptability since I’m hoping the AVX won’t be the last mount I ever own. The ½” steel baseplate is welded to the 8” dia. - 3/8” wall - steel pier and the holes are the same as the ones in Dan’s 8” aluminum baseplates. With this set-up –if I ever upgrade the mount – I just get the adapter plate from Dan, then bolt it on and done – no further mods required. This is a surface to surface interface with no vertical bolts to induce deflection and all the fastening is done through the owl’s nest. The cables from the warm room (USB, etc.) will be routed through a conduit inside the pier and then exit through the hole to keep them off the floor. Still need to cut a small hole near the bottom for the power cord which will be routed down through the pier to a 110v receptacle beneath a small "trap door" in the floor. Cutting that hole should be easy compared to the owl’s nest which I cut by hand with an oxygen/acetylene torch. Here’s a good article on pier design and although I’m not a member of that particular forum – it’s the best research material I could find. http://www.cloudynights.com/page/articles/cat/articles/how-to/pier-design-fundamentals-r1236 Starting to get excited now...

    Ok, today I was finally able to put the debayered sensor in a test 350D body and test it. I was happily surprised it still worked. I was 100% sure it was dead since I tried almost every trick in my book to try to get it cleaned. After putting back the filter frame I found it not particularly hard to stay away from the fragile gold wires or from the little circuitry on the side of the sensor while I was still able to remove most of the CFA layer at the edges. I had the feeling I could have removed all the visible CFA layer if I had wished... After removing the mini lenses and the CFA layer with my cordon-blue stick using a 2x and 4x magnifying microscope I tried to clean it with demineralized water. This didn't work out well so I tried to get IPA but my local pharmacist doesn't sell it. I bought some denaturalized alcohol (96%) and cleaned the sensor with it repeatedly. still not really clean, after that I threw the sensor in a ultrasonic cleaning bath (I was sure it was toasted after that) and after this treatment the sensor surface still looks awful!!! Also I worked the CFA layer a bit too hard in some area's. I should have let the Commandant 5 polish do its work instead of applying too much pressure on the cleaning stick. By doing so I managed to scratch the golden sensor layer in multiple areas which probably has caused the non working vertical line in the images below. Anyway, I'm still very pleased the camera and the sensor still work and disassembly and assembly of this first 10 euro test body produced a working debayered camera!!! Debayered Flat: Test Image:

    I didn't expect to be updating this so soon but I couldn't resist the chance to acquire a Pan 41mm and Delos 4.5mm when trazor (Terry) posted an ad in Classifieds yesterday. I have been waiting for both to come up for a while so it was great to grab them together Here they are with their smaller cousins that I have picked up in the past three weeks or so... My 32mm TV Plossl has gone as I had bought it for my Lunt 50Ha but they just didn't like one another. My Baader Classic Orthos need a new EP case to live in so are currently squatting in a refractor case.

    I found another "obscure" nebula close to the Cat's Paw Nebula (NGC 6334 - http://stargazerslounge.com/topic/246326-ngc-6334-the-cats-paw-nebula/).There is so much objects out there waiting to be discovered when you are starting out... It's just great! I was going to continue my collection of Messier objects, but then I got side-tracked by something I even hadn't heard before. Anyway, I thought I share this one... it's big, it has a lot of structure and I love it . Clear skies! HJ

    Thanks for the comments Gav, xtreemchaos and Sara, really helps with the motivation! Yes, I'm pleased with the results thus far. I was concerned about the potential loss of contrast with these mid-summer nights and am re-assured. Also, barely any NR too (just to bring a smile to Sara ). The nebula is littered with Bok Globules and dark dust which gives contrast and interest as we know. I was however, pleasantly surprised to see the two tiny Globules to the right of the end of the curled trunk. These are clearly seen in this beautiful image from Eric Coles - big scope and dark sky, http://astrob.in/186073/B/.

    Hi all, This is a work still in it's early stage but I thought I'd share it, it's NGC 6888 the crescent nebula captured with the little SW ED80 with 0.8X reducer and mono & TEC cooled Canon 550D, this is proving to be very hard to get due to neverending bad weather, first day of summer now and it's almost raining here! I'm hoping to at least double the integration time in Ha (3 hours now, 9x20 min. subs @ 1600 ISO) and add the OIII later, si this will be a bicolor image, let's see if I can extract the fain OIII halo of this object from my city backyard, well now all I have to do is wait I guess... https://www.flickr.c...eposted-public/ Crop here: https://www.flickr.c...eposted-public/ Hope you guys enjoy Cheers and clear skies, hope you get better luck then I do.

    Dom, Have you tried using this tool to work out the effect of different eyepieces on what you can see through a particular scope? http://www.12dstring.me.uk/fovcalc.php I find it very useful in terms of determining the field of view v magnification you will get for a particular combination, particularly if you use a very familiar object such as the Moon, Jupiter or the Orion Nebula as the selected object. Your Skyliner 200P is a great scope and at f5.9 is at the slow end of what would be considered a "fast scope". This means that you don't have to break the bank on eyepieces to get great views through it. When I had my 200P I used a set of Celestron X-Cell LXs that were fantastic with it and available 2nd hand for £40-£50 each. From what I have read on SGL your BSTs are at least as good as the X-Cells. As Alan mentioned above the Maxvisions are very good but they are also very heavy. You are also introducing the complication of having a mixture of 1.25" and 2" eyepieces, which some people find annoying during an observing session as you have to switch a reducer in and out when swapping from low to high power. It's something you get used to, but I remember not liking it when I first ventured into 2" EPs. If you want to slowly build yourself a set of very high quality EPs for your current scope and that would be future proof for stepping up to something more demanding I would recommend the Explore Scientific 82° range. If you are getting the 6.7mm (which is fantastic!) for your birthday you could drop some hints about an 11mm for Christmas As for filling other gaps I would recommend sticking to lower cost, good quality eyepieces as a temporary measure. I found the 32mm Celestron Omni Plossl to be an excellent low power EP in the 200P and you can usually pick those up on Ebay second hand. In all honesty, you will mostly use EPs of this sort of focal length as finders so spending tons of money doesn't make sense until you start to step up into more demanding scopes that will allow you to see more. Given your age that is for another time, but you can have some fantastic fun with the kit you have and start to build a great collection of EPs slowly over the next couple of years and you will be ready to rock One final piece of advice - buy second hand if you can (Ebay or, preferably ABS) - Astronomers treat their eyepieces more carefully than babies so you can normally be assured that they are in good condition. Always ask for photographs and never buy anything that has a "stock" photograph from the manufacturers website. Be wary of using the Wanted option as it sometimes attracts scammers. If in doubt contact someone here to ask for advice. Good luck! Derek

    Yes, I think I am getting close to having all the eyepieces I need, Stu I will post some thought on the P41mm in due course but what I will say now is that ( a ) I blame Alan Potts for telling me some time ago I needed one and ( b ) having just had it in my Baader Wedge in the ED100 I completely agree with Alan that I needed one! More granulation than I have seen through any other eyepiece and the sunspots are as crisp as a really crispy thing. Lovely. I have had the E8 and D10 for quite a while and both perform excellently. I thought about selling one but find that having the option can be very useful when the skies aren't perfect (i.e. all the time) so plan to part with the D10 and buy an E10 instead. The thing at the bottom is a prototype of the DRT65 Automagic Cloud Blaster - still needs some tweaking but look out for them on ABS & Ebay soon ...or it might be an LCD torch with white, red, blue and green filters

    Seeing conditions were fair to good on the 22nd during the late afternoon in North Somerset. Had a chance at leaving work early so I made the most of it and got set up and was pleasantly surprised by pretty steady conditions for around 30 mins or so. After this it started to go downhill but luckily I got a shot of the very nice active region 2371 plus some prom action whilst the going was good!! A few more to go though but these are probably the best I think. Regards, Pete

Conditions: Pluto around 20 degrees above horizon on each occasion, skies SQM 19.7, 19.5, 19.3 (moon!), temps 18, 20, 24C at 00.30 (hot!). Seeing or focus or collimation or all three a lot poorer on the third night. cheers Martin

    You mention 6.7mm as very high power. I chose a 6mm William Optic, only because there is no 6mm Starguider available (yet) ? Using the scope numbers, 1200-200-f/6 any 6mm will match the technical aspect of this telescope, giving 200x power, which the telescope is easily capable of. I even go as far as 375x on the Moon, but useless on Jupiter at this power. Theory suggests twice the aperture is my maximum, therefore a 3mm EP 400x. The 3.2mm I have gets used on the Moon to impress folk, if they can keep up with the tracking? But its use is limited, but is part of what is now, my EP kit. A 12mm BST Starguider would be a good option. The 12mm hits the so called sweet-spot on this scope, and if Barlowed, gives you 6mm/200x. My choice for my wider EP stemmed from the fact that the stock 25mm works ok, but is pants from my observatory, especially looking at M31. But from a darker site, its a good EP, although my BST gives me a slightly wider fov at 60° , but the Panaview at 70° now satisfies my needs. EP selection is very subjective. Only you will know whats right after using them. Whats good for some folk, wont work for others. I'm very happy with my present setup, but we all know, there is better out there? I would love to see through the 10" 12" or maybe a 16" scope, aside my 8" under the same sky. I know on paper, technically, there will be some improvement, but under the same identical conditions, if the result is not alarmingly different, I think this 8" will last me a lot longer. If/when I upgrade, i know that my EP kit will possibly change to accept the faster focal ratio, but whoever is fortunate enough to buy my system will be getting a very good system from the start.

    Good idea to find out how well yourself and the RACI get on, and you have the thing now as well. Unlike most here I cannot get on with a Telrad, I would be better with 2 pins pushed into chewing gum to act as a sight. :eek: I have no idea why the apparent incompatability but having tried one before considering buying I at least know the situation. I find RDF's good for myself however. :rolleyes: As said a bit of a strange world. :grin:

    My other half loves the hobby as much as I do - but in a different way. She likes me to find stuff so she can have a wow moment looking at it or imaging it. But she has no interest in comparing, buying, and talking about gear or researching objects - she leaves all that to me. She encourages me to buy any gear that I suggest would be useful - including bigger/better scopes, eyepieces, and mounts. Some would say I'm lucky - they'd be right lol. Equally - I'm supportive with anything she wants to do - fortunately she doesn't have any expensive hobbies like astronomy - mostly cooking, buying the odd kitchen gadget, and keeping current with computer technology and devices. lol.
