  1. This is my first try at M33 - the Triangulum Galaxy - taken on bonfire night, 2012. It was a bit misty (maybe thanks to the fireworks!) and so the subs were rather noisy - disappointingly so... but actually given that it wasn't particularly clear I am not unhappy with this so far. I had the narrowband filters loaded in the filter wheel and so only took Lum data. This is 5 1/2 hours of data in 10 minute subs, TS90 APO triplet f/6.7 taken with an Atik 460ex, guided with IMG0H and PHD. This lot mounted on my CG-5. Stacked and stretched in AstroArt 5.0 with a gentle low pass filter applied to try to calm the noise in the background. I think I'd do much better on a clearer night but given the weather this year I am taking everything I can get... I will add RGB when I get the chance and I am actually not sure if this data will be good enough to form the Lum layer...
  2. I've reprocessed the data of IC410 that I captured earlier in the year. This is 24 x 600s Ha and 22 x 600s OIII - the OIII was captured using my FSQ-85 and the Ha combination of the Baby-Q and my TS90APO. I had somehow manged to combine the data using DSS earlier but couldn't get it to work reliably and so I ended up buying RegiStar to get the different field of views to combine properly. Scopes: FSQ-85 and TS90APOc Camera: Atik 460ex mono with Baader 2" filters Guiding: Atik OAG, IMG0H, PHD Mount: CG-5 Registered in RegiStar, stacked in DSS, and processed in PhotoPLus X4. I've had trouble getting the colour balance right as there is a fair of mount of nebulosity in the background; I'd be really interested in comments as to which of the following looks best. Thanks for looking!
  3. I had an unexpectedly clear night last night - the best for ages... I managed to get some SII subs for IC 410 but when that disappeared below my horizon I pointed the scope at M105 to see what I could get. Now the focal length of the scope I was using (Tak FSQ-85) is less than ideal and I had the narrowband filters loaded up, so this was just a bit of fun. 30 x 300s subs, L only. The pull out is obviously a crop from the main image.
  4. I've had another go at processing the M33 data that I captured earlier this month... I really liked the understated colours in the image posted by Betelgeuze last month and while I haven't done anywhere near as good a job as him I think I've managed to sharpen it up quite a bit over my previous effort. Still learning how to process, but I think I'm getting better so thanks for all the feedback. This with my standard DSO kit: Atik 460ex, TS 90 APO on a CG-5, guided by an IMG0H and PHD. Lum 30 x 600s & 4 x 1200s; R 5 x 600s; G 3 x 600; B 3 x 900 Stacked in AstroArt 5, processed with PhotoPlus X4. Hope you like it!

  7. I have a Celestron 8" with CG-5 Mount that I purchase about 14 years go. I have not really used it much since due to family and work pressures but as I am close to retirement I am re kindling my interest in Astronomy. Over the years I have lost the polar scope an have been attempting to purchase a new one. My local astronomy shop had what looks to be the correct one in stock bit it would not fit. I Tried both the CG4 and CG5 polar scopes but the tube is too wide. The polar scope for my old mount must be thinner than the later ones. I have contacted Celestron but they can't help. Does anyone know what the problem is or where I might obtain one for the older mount. If not are there any other methods for performing polar alignment without using the polar scope. I have heard of some software that does this but only with GT mounts. I would eventually like to do some astrophotography but it appears that polar alignment is critical for good results.
  8. Clear and cold here so I decided to get some RGB to add to the luminance data of M33 that I capture last week. This taken on 5th and 10th November 2012 from South Oxfordshire, UK - sky not improved by firework displays on both nights! TS90 APO scope @ f/6.9; CG-5 mount; Atik 460ex camera guided with QHY IMG0H and PHD. Exposures (all binned 1x1); stacked in AstroArt 5.0 and processed in PhotoPlus X4: L - 4 x 1200 sec & 25 x 600 sec R - 5 x 600 sec G - 5 x 600 sec B - 5 x 900 sec I'm not sure if I've overdone this so would welcome any comments. Also when posted on here the sky looks a bit too blue to me, but I haven't been able to solve that without impacting on the galaxy itself. I seem to recall reading something (I think by Olly Penrice) about learning what targets respond to best - I totally get what he means having processed this and I think I will try again from the very beginning with this data at some point. Thanks for looking!
  9. Hi all, I've previously posted a bicolour version of IC 410 but the other night I managed to captured some SII data so what follows is a Ha / OIII / SII narrowband rendition of the Tadpoles. Usual set-up for this kind of thing (CG-5 mount, Atik 460ex, Atik OAG / IMGOH / PHD), but the Ha was captured with both my TS90APO and FSQ-85. Ha 25 x 600s OIII 23 x 600s SII 29 x 600s The different fields of view from the twio scopes were reconclied in RegiStar, stacked in DSS and processed in AstroArt 5 and PhotoPlus X4. The first of these is what dropped out of the processing, the socond has had the stars tamed by blending in a layer that has had teh AA erosion routine applied. Then followed endless tinkering to try to get the result to look okay on SGL! I've no idea why but images that look fine on my desk top take on a green or magenta hue when posted on here. Maybe part of thr problem is that I don't really like to leave the sky really black as I don't think it looks natural... but on this one I've gone pretty dark! Hope you like it! I feel like I've got some good data here; in fact I think that this is the first time I've had decent data for all three channels. It probably has more to give but I am pleased with this . Thanks for looking. Higher quality version of the above here. Higher quality version of the above here.
  10. Hi all, Long time since I've managed to capture any data - mostly due to weather but also work commitments. Anyway, inspired by LDUNN1 and this thread http://stargazerslounge.com/topic/154380-m27-and-first-light-atik-460ex-mono/page__st__20 I decided to nip out last night and make the most of an hour or two of clears skies (quite remarkable given the weather elsewhere in the UK!). I've been having trouble with my OAG, so spent much of the clear spell setting that up again. Then pointed at M27 and snapped away. Unfortunately the clouds rolled in before I could get any G or B data so this is L only. Hopefully I will grab the other channels but my imaging has been frustrated by the weather and objects disappearing at my location before I can get the colour data! So this is another B&W - a shame with such a pretty target - but hope to add the colour and some Ha at some point. Do love the star field though. TS 90mm APO CG-5 Atik 383L+ mono / Atik OAG / Atik EFW2 w/ 2" filters Autoguided wirth PHD and a QHY IMG0H 4 x 300s subs, no darks, no flats, no processing (just a straight stack this morning before heading to work). So lots more work with this one, but just wanted to post something because it's been so long! Full frame image is, by the way, exactly where the GoTo landed. Had a good guidestar in view and knew the cloud was coming!

  14. I picked up an older CG-5 mount and tripod the other day for $50. It's in good shape, just a bit dirty. The Dec axis moves freely with the clutch loosened, and drives very smoothly with the clutch tight. The RA axis drives very smoothly with the clutch tightened (bear in mind this is a totally manual mount), but is stiff to move with the clutch loosened, and has a couple of spots where it is very slightly "notchy" when it is turned. How can I loosen this up, to make hand-skewing to a target easier? It has no polar scope, no big deal, and has provisions to add tracking motors, but I doubt I'll do that. I bought it to have a simple, grab-and-go mount to throw the frac or C6 on to look at the moon, etc. It's usable as-is, it tracks nicely with the worm drive, but I'd like to get it back to its "former nights of glory" condition. I think it may be as simple as re-greasing the bearings, but I'm not sure what I need to do to take it apart. There is a collar that has two small holes for a tool like a circlip plier, located underneath the RA setting circle ring (at the bottom, where you'd insert a polar scope), looks like that has to come out to break the RA bearings apart.

  17. I was very excited to get a couple of hours of clearish skies last night to get first light with my Takahashi FSQ-85. It turned out to be something of a comedy session, however. Firstly, being a cheapskate I hadn't bought the Takahashi clamshell and opted instead for some 95mm tube rings. Trouble was, mounted to a fairly short dovetail I wasn't able to balance the scope properly; it's no biggy but I need a longer dovetail and to raise the rings slightly so that the dovetail clears the focuser... Secondly, my dew strip packed up for some reason. Not sure what's wrong with it or if it can be salvaged, but the wires feeding the strip were getting plenty warm, but the strip itself wasn't. It's barely been used so not sure what to make of it... Anyway, it meant the optics had slight misting for the latter subs. I am hoping that this explains the halo around 19 Auriga in the top left. The final thing was pure stupidity though. I somehow managed to turn off the TEC on my CCD camera so the subs were at ambient temperature and therefore very noisy (in comparison). Combined with high whispy cloud this can't be seen as any kind of test for the new scope. In any case, I expect it to come in to its own dealing with blues... so we'll see. Anyhow 10 x 600 sec subs Baader Ha filter. Mount: CG-5; Scope: Takahashi FSQ-85; Imaging cam: Atik 460ex; Guiding: PHD & IMG0H.
  18. I had a few hours between the clouds last night but the moon meant I had to go for something in narrowband, so given it's almost Halloween I thought I'd have a go at the Witch's Broom. Unfortunately I didn't have my dew band cranked up high enough and failed to notice the optics fogging up so this is a bit soft but I did get just about enough data to produce an image. This is with my TS90 APO triplet, on my CG-5 guided with PHD using an IMG0H as a guidecam and is effectively first light for my new Atik 460ex. Ha 12 x 300s subs OIII 4 x 600s subs SII 4 x 600s subs All binned 1x1, stacked in AstroArt 5 and processed in Serif PhotoPlus X4. Processed them in a few different colours, and I am afraid I may have overdone it a bit - which do you prefer!
