    I think this is only about my third go at LRGB - Managed to finally get my guiding sorted the other night as well, the first few subs still had trailing, so I offset the balance and voila! Perfect subs for the rest of the night. This time I followed the Light Vortex stacking guide, and did drizzle stack, so apologies for the size of the image! This is 11X5min L and 7X5min each of RGB. I think I will revisit sometime as I don't think the red channel is properly aligned - as the RGB was not drizzle aligned I could not get Pixinsight to register the RGB data against the L until I rescaled the RGB to the size of the L, thought it would just have done this itself? Anyway, any comments etc always taken, have I gone to far/not far enough with any of it....

    The fourth and final stargazing report from my summer vacation on Benguerra Island in Mozambique. Starting at 1:30am and finishing at sunrise, I covered a lot of the central Milky Way favourites as well as exploring the galaxies of Fornax and Sculptor, as well as numerous globular clusters and nebulae. (and a mid July view of M42!) I finished with an attempt to spot some structure in the HST. The report is on the link: http://alpha-lyrae.co.uk/2019/10/27/an-early-morning-stargazing-session-on-benguerra-island/ I set up the camera taking a lot of pics while I stargazed. Guess I was switching eyepieces at this moment! Feedback always appreciated. Hope you enjoy it.

    Most deep sky objects are just smudges of light even with a 9.25 inch scope. Filters such as the O-III and UHC type do help make some nebulae stand out more. The views with a scope don't generally look anything like the images you see of deep sky objects because those are captured by highly sensative CDDs and are the results of many minutes or hours of culmulative exposures. Light pollution and moonlight can make even the brighter deep sky objects difficult to see. They will seem more impressive if viewed under really dark skies but still won't rival the images I'm afraid. Practice does help the eye to pick out deep sky objects. M81 and M82 are a couple of the best galaxies. M101 and M51 are somewhat fainter because they are face on to us.

    Had about 3 hours with wonderful clear skies last night to try out the Morpheus. Everyone was right it is a stunning eyepiece. I particularly liked the neutral tone of the eyepiece. I also liked the M43 extender which really helped with the eye position. I assume the extender can be bought for the other Morpheus in the range? I was surprised just how well it worked with the Sharpstar 61 EDPH. At F/5.5 it's a steep light cone. I see other Morpheus coming this year. More money to FLO Well impressed. Glen.

    I was out at night on holiday at the Isle of Wight enjoying the dark sky when a big grunting badger came past me, oblivious to my presence it seemed. Scared the socks off me though! I`ve got a bat detector which comes in handy to help decide if I am being buzzed by a bat instead of some kind of giant flying nocturnal insect with fangs. The worst thing for me back home is when the cat decides to jump in the observatory half way through a crucial observation and takes great delight walking on the laptop and tripping over the cables.

    Here's my not very good image, with the identifiable blobs marked. This image is the 'right' way up, non-reversed. Note that with a SCT if the camera is not looking through a diagonal the image will not be mirror-reversed. Some of the objects in Stevewanstall's image are stars, others are moons.

    Hi all, Ok ok, I know this seems like a silly thing to ask, but I'm willing to bet that many on are wondering the same thing. Basically, Ive lived in central London my entire life up until 2 years ago when I moved to the sticks. Far enough out to get B5 skies. Now I know that there is pretty much nothing in the UK that will pose any danger to me In my garden. But even so, yes, I get spooked by rustling noises and movement in the nearby bushes. Stupid I know. I tend to make regular loud noises to scare anything off (stop sniggering)... That's all well and good, but my question is what's it's like being alone in a garden at, say 1am in the middle of nowhere at a dark site in Wales? The wife and I have found a B&B to book when the weather is going to be clear and the plan is for her to stay in the cosy room while I am outside. As I said, I know that there isn't anything that will attack me, but from people's experiences, is nature noisy, brave spooky etc in a situation like this? As a side note, one anmial I do love having around me at the start of my sessions is the tiny, acrobatic bat that swoops a few feet above me for hours...amazing to watch. He come pretty low over my head sometimes but I never flinch. He's my little friend. Haha.

    The 732-member WBL catalogue of galaxy groupings tend to have relatively sparsely-distributed members and differ in this sense from the more compact groups such as the Hicksons (although some Hicksons are also members of the WBL catalogue, I think). Armed with nothing more than RA/Dec, I often like to dip in to the WBLs just to see what is there, as these are under-appreciated objects and don't appear on (m)any charts. The results can be quite varied, but typically consist of 3-7 galaxies that fit on my small sensor. Here are 4 from last night. WBL 676 is very close to the bright star o AQR and consists of 5 main galaxies, though a sixth mag 18.6 galaxy is also visible as a fuzzy blob just N of a star. The lowest galaxy is NGC 7182. I'd say this is a fairly typical (not particularly exciting) WBL object type, with the galaxies strung out across the field. Seeing was quite good through most of the session but seems to have deteriorated for this object. Nearby is Shakhbazian 81, a very challenging compact group of about 11 faint galaxies. Also in Aquarius is WBL 669, a 3-member group. Again, nothing particularly spectacular. Aquila contains just one WBL group, again a triplet. I enjoy looking for WBLs in star-rich constellations as the combination of a dense star field with galaxies in the distance is appealing and unusual. The 3 galaxies form a near equilateral triangle with the base composed of mag 14.2 Sc type UGC 11524 and mag 14.7 SBc UGC 11522 which are at a distance of around 250 M Lyrs and may well be interacting. Finally, back to Aquarius for WBL 666, one of the six WBLs in that constellation. This is a real beauty, with 7 individually-interesting galaxies in the field, and it is finding configurations like this that motivates me to explore the WBLs. I reckon this would make a good AP target. Interestingly, these galaxies are all at a similar distance of 180-200 M Lyrs so may be a physical grouping. On the inverted shot I've marked the 5 NGC galaxies and a couple of quasars. Q1 is mag 19.5 with a redshift of 2.06 (8-9 billion LYs?), while Q2 is mag 19.6 but much closer, with a redshift of 0.18 (around 2 billion). The non-inverted shot is an LRGB as I decided to add a little colour (although it is mainly luminosity so the effect is subtle). Thanks for looking Martin

    As John says M101 and M51 are quite a bit fainter I've never seen them from home I was lucky enough see M51 in a 22" dob in Buxton what a site that was.

    Wanting to show a fantastic view of something is a nice idea, sometimes this desire can put extra pressure on, but really we (well me) are only observing for ourselves and if someone else likes it great. A neighbors grown children from far away expressed honest desire to see my equipment and outdoor obs, which I showed them. Next year they are invited to come over to look up and they are excited! In truth the only jaw dropped on the ground I care about is mine lol! if someone elses does bonus!

    Based on the forecast I have now commited to not bringing the imaging setup, but will stick with the LX10. I'll be learning how to use it pretty much from scratch so if anyone is free and able to offer any tips on aligning and using the Magellan unit I would appreciate picking your brains.

    The cricket field is ok if Reading still use it and you want to join, but access to the field is a bit tricky from the road especially with a lot of gear. When I used it a few years ago, you need to contact someone who then contacts the owner and then they have to text you back, and then Reading would advertise that on the FB page, so anyone whom you don't know might turn up. They seemed to want to turn any visit into a group visit. I did manage to secure independent permission for use but never bothered in the end. As mentioned Swallowfield and the area between Reading and Basingstoke might turn something up, skies are a bit darker there although at the Reading end of things the LEDs on the M4 have made things worse. One of our dark sites are there, permission from an angling club I use with a gated car park, but I am only visual so the occasional angler turning up with lights on is not really an issue, think it might be for imaging. I recommend looking at the OS Explorer maps for the areas and going out in the daytime to identify safe places, see them at night as well then draft a letter up asking for permission for anything that is suitable. Car parks, farms, small holdings, allotments, church car parks, etc. Its worth the effort to find somewhere.

    Just invested in a Prima Luce Eagle 3S which I bought through 365 Astro. Arrived within the day, more importantly Zoltan helped me out where the manual failed to do so on the initial set up and connection to the remote PC. 5 star service. Thanks I'll do an unbxing and set up review later. I bought it now as the forecast is rubbish anyway

    Here is my current work so far on IC410 'tadpole nebula' It's a combination of 31x20m ha, 14x20m oiii and 12x20m sii. I intend to collect more data as it passes over my house this winter. A special thanks to Olly Penrice, Vincent from the astro pixel processor forum and Sarah Wager (Swagastro.com) for their help with imaging tips and techniques anyway... here it is!

    I think I'll chuck the Star Adventura in the car with the ASI1600 and one or two Leica Primes. Might have a look at M31. Debating whether to buy a shorter eyepiece than my 9mm Meade 5000 for the Megrez 90 (621 mm fl).

    Hei Sqren, A couple of years ago I gave my HEQ5 Pro the Rowan belt mod, and recently I did the RA overhaul. I never replaced the big bearings, just the two small ones, and I did not touch the DEC department at all. For lubrication I used ("Biltema 36-1861 ") chain lube for bike chains which is very sticky. It works very well now. I would say that with the symptoms you describe, the most important parts to focus on are 1) the two small worm bearings (just a small axial tension after you put in the new ones), 2) the worm belt pulley (do the belt tooths engage perfectly over the whole circumference ?) and 3) too little backlash may cause intermittent binding when temperature falls. Also, the taper bearings - I only tensioned them by hand (without adrenaline =:) Ragnar

    A decent night tonight without a moon. Naked eye limit around mag 5 towards the zenith. Milky way visible faintly through Cygnus and the Andromeda Galaxy just about naked eye visible with a little averted vision. Not the best I get here but not too shabby either. I've been giving my favourite deep sky object, the Veil Nebula, some scrutiny tonight with the help of my 12 inch dobsonian and trusty Lumicon O-III filter. The 21mm Ethos and 31mm Nagler eyepieces show big enough chunks of sky to take in large segments of this complex network of related nebulosity, but not the whole thing of course. To get much out of the Veil Nebula a narrowband (ie: UHC) or even better a line (ie: O-III) filter is required it has to be said. The main segments of the Eastern and Western Veil and Pickerings Triangular Wisp are bright, extensive and well defined tonight. As my eye becomes more fully dark adapted fainter elements have become visible giving 5 NGC objects in total and a few other bits and pieces too. On an even darker and more transparent night I think I could go deeper still but pulling out what I have of this marvellous object has been very satisfying I've marked this chart of the Veil Nebula with my definite sightings so far. Yellow ovals are the easy portions, green ovals are objects that took a little more time to tease out. I have also had fleeting glimpses of other ill-defined patches as well but I've just recorded the stuff I'm sure of currently. My view through the newtonian is inverted with east and west reversed of course. The chart is the normal orientation view that our eyes see. To give an idea of the scale, the chart covers an area about 3.5 degrees by 3.5 degrees. With the 31mm Nagler I can get in the whole of the NCG 6992 / 6995 / IC 1340 segment in the field of view. With the 21mm Ethos it's a touch less. This really is such a complex and rich object - you can easily spend a whole session exploring it (I've spent over 2 hours on it myself this evening). Here are some links to articles which help delve deeper into the Veil Nebula: https://www.skyandtelescope.com/astronomy-blogs/explore-night-bob-king/explore-veil-nebula/ https://www.skyandtelescope.com/observing/beyond-the-familiar-veil/ https://www.astronomy-mall.com/Adventures.In.Deep.Space/Dissecting the Veil Nebula.html
