    Here's my 2nd image of 2020, mostly captured later on the same recent run of clear nights that I was imaging IC342, though I did capture the Ha earlier in Dec when the Moon was up. The image comprises L=21x600s; Ha=9x900s; RGB(each)=24x300s, all captured through my C14 XLT plus Optec x0.67 telecompressor, with my QSI583wsg-5 camera using Astronomic filters . I would have liked more Ha, but since the forecast for the next few days is not good, I thought I'd take a look at what I already had, so here it is... Thanks for looking.

    This Ikea Molte chair was an eye-watering £9 or so seven years ago when I bought it. My wife disliked it, so it's been outside for well over six years with no protection and was looking sad. I needed a simple, light adjustable observation chair for my new 300p flextube which is really low for me except near zenith, so decided with a few very easy mods, this would fit the bill. I drilled extra adjustment holes in both the post and base to gain as much height as I could. The lowest setting was already adequate. To lock the height in place I now use a phillips screwdriver with a 6mm shaft in place of the original small adjustment key (easy to lose), so height changes are fast and easy in the dark, as the chair now has a decent-sized plastic handle (and a built in screwdriver!). I then took the plastic seat off, quickly scuff-sanded the base and post, and then sprayed it with leftover red zinc oxide primer from a car repair, dried that with a hot air gun in a few minutes, then laid on a heavy coat of clear lacquer (also leftover stuff). One last touch today - a Harris Tweed seat cushion my wife made from a £5 remnants bag from the outlet at Tarbert, Harris a few years ago. Posh eh?! Final touch later this week, but not an absolute necessity, is to add some 2-3 cm tall furniture feet on the bottom of the legs to gain an extra few cm height, and a roll of black closed-cell foam is coming tomorrow for my DIY flextube dewshield, (sorry Astrozap, you are too dear!). I'll cut the foam to fit the seat and glue two layers on, with the tweed cushion thrown on top that should be pretty comfy for some relaxed observing I also have glow in the dark tape, might put a few bands of that on the feet. NB - If you want to try something similar, note I'm fairly tall so didn't need a ton of height, so you might want to take measurements to determine what your min/max seat height is. Fortunately no one was home to see me do squats while measuring how far off the deck my gluts were, a disturbing scene, no doubt What DIY observing chairs do others use?

    Hi. I had a go at imaging NGC1977 or The Running Man Nebulae.You often see this Nebulae combined with M42 when imaging a wider field. It was taken last night with my ED80 and Atik 314L+ ccd camera. I shot 18x600 second subs for the Luminance,and 12x600 second subs for the RGB.This is an LRGB image.The centre stars are very bright and nearly overwhelm the image.They showed up quite bloated in the L and B Frames,and were difficult to control in processing.I don't think I have done a great job with this. Full calibration frames were applied. Cheers. Mick.

    I had seen this on offer, including Cheshire EP, AstroZap dew shield, and Bahtinov mask on a Dutch website, with the asking price dropping steadily. On my birthday (January 21) it hit €165, and my restraint gave way. I collected it today, and it is in perfect condition, with upgraded dual-speed focuser. It should fit neatly between the APM 80 mm F/6 triplet, and the Celestron C8. I intend to use it for wide field viewing, and imaging of smaller DSOs. The GP-DX mount should easily handle both the weight and focal length of this scope.

    Venus is now at a very respectable altitude, plus some lovely clear skies. Perfect conditions (hopefully) to begin imaging it again. Both images with Celestron C9.25, Asi290mm, Televue x1.8 Barlow and Baader UV filter. 25,000 frames captured, stacked 10%. Last image is with a Astronomik 807 filter. Some nice detail visible on both days, particularly Saturday afternoon. It looks clearly like rotation visible to me over the 2 days?

    Here is my 3rd and final pic from Monday nights wide field imaging test session. IC410 the tadpole Nebula and IC405 the flaming star nebula, really pleased with the field of view on this as its the perfect size to just capture both. 12 X 10 mins in Hydrogen Alpha with my Atik 460EX CCD & Altair Starwave ED70 refractor + Lightwave 0.6 reducer bringing it down to F3.6 @ 250mm FL. Guided, captured, stacked & stretched in MaximDL, processed in Photoshop. Lee

    First image off the dual ED 150 rig with the ASI 178 cameras on board. The image is unfortunately very heavily cropped, mainly because I had a really hard time getting the two cameras aligned. Over two hours had elapsed of clear sky trying to get them close and I was determined to get an image from the session. NGC 2336 is a spiral galaxy in Camelopardalis some 100 million light years from Earth, discovered by Wilhelm Tempel in 1876. Capture Details: Lum 106 x 60 sec ASI 178 with retro fitted Peltier cooler, captured with Sharpcap. RGB each 25 x 60 sec ASI 178 with retro fitted Peltier cooler, captured with SGP. Dual Esprit 150 refractors on Mesu 200 Mk 1 mount Calibrated and stacked in APP, processed in APP and GIMP. Thanks for looking.

    I got my 1st scope, an heritage 130p and today the weather finally cleared up for a quick out. I live in a major city and after a short 20min stroll I arrived a big park where I planned to observe (the heritage can be carried without too much trouble, but I need to figure out a backpack solution). Conditions where I think as good as they were going to get for my inexperienced star gazing. I had planned to focus my attention on Orion but I was fouled by trees blocking most of the constellation. My so saved the session by suggesting we look "over there", I wasn't sure what it was but it was the Pleiades and what a beautiful sight it was on the 25mm. I had fun poking around the sky, looking at venus (trying 130x I could actually see a crescent shadow) and at some of the brighter stars, vega and pollux mostly. Towards the end I decided to revisit the Pleiades again trough my binos and sorely miss a support but good views nonetheless. All in all I would say it was a great, albeit short, first session. It was getting a bit cold but it was immensely pleasurable to be out learning the night sky. Cant wait to go back out again, especially in more favorable skies.

    Here's a capture this evening of the Eskimo planetary nebula in Gemini (NGC 2392, Caldwell 39). It's easy to see and find, being bright at magnitude 10, but rather small and difficult to capture the very odd fine details. It's also in a very sparse star field, so there's not much else to see here! Omegon RC8 (1600mm FL), Atik 428ex, 15 x 180s exposures each of Ha and Oiii. Synthetic green. Field of view: 14 x 18.6 arc mins.

    On Dec 28 I had a nice view and took some photos of a thin crescent Moon. As it happened I managed to continue this every day until Jan 2nd. I then decided I may as well try and get in as many days photographing the lunar phase and observing the Moon during the current lunation. That is starting from the date of the last new Moon (Dec 26th) until the next one on January 24th. It became rather addictive and to extend the sequence of days my behaviour became rather extreme at times - and strange to my non-astronomical neighbours. Frequently out in cloudy skies just waiting for a break, and walking up the road with my setup if I couldn't see the Moon from my backyard. On a couple of occasions I was actually out taking pics when rain was falling. One of these was whilst trying to hold an umbrella over myself and the telescope/camera as the rain became more persistent. Well, how did I get on? Dec 26th. New Moon. Dec 28th to January 8th. A sequence of 12 days in a row. Jan 9th cloudy, not looking good for the penumbral eclipse on Jan 10th. Jan 10th Managed to see about the first 40 mts of the penumbral eclipse in difficult conditions. Jan 11th to 12th, clouded out both days. Jan 13th to Jan 22. A sequence of 10 days in a row. Jan 23rd. The Moon will be too close to the Sun for me to catch it apart from in daylight hours. Jan 24th New Moon. So, in summary I photographed the Moon and observed it on a total of 23 days during the period. I'm very pleased with this, especially considering that on the day of new moon and the day after/before it's not practical to observe. From the start I decided I wasn't going to observe during the daytime. I really had a great time and enjoyed it tremendously, though toward the end when I was getting up in the early hours it was hard going. The only reason I had the time to spend on my Moon Marathon was because I am recovering from an op and didn't have to go to work, every cloud has a silver lining! For all sessions I used either my SW 80ED on an AZ5 or my SW 120ED on an Ercole mount. All pics are single frames taken with an Olympus E-M5 Mk11. Below are a some of the numerous pics I took. There are included because I like them for various reason, rather than any particular merit they might otherwise have.

    Just starting out on this journey...NGC 3184. Believe it or not, but this galaxy is over a full magnitude dimmer than IC-342, which came as a real surprise to me. Conditions have been quite bad--despite having been forecasted to be pristine (never understood why a live forecast would read "clear" when the sky is like pea soup). Despite the conditions I was pleasantly surprised by the data. I have collected over 100 subs, but have thrown out more than half due to elevated FWHM values. This is 45 300 sec Lum subs. taken with TOA 130 and ASI 1600. I know I need many more--and better conditions I think will tighten things up and bring down the FWHM. Warning...This image has not been processed for full resolution viewing. I know the bright stars are showing signs of the dreaded ASI 1600 diffraction pattern--but you should have seen them before I knocked them down a bit. created this stack using two versions--one stretched for the galaxy and one stretched for the background and stars. Not perfect, I know, but I think in the end, when I am fully committed to processing a full data set, the artifacts around the brighter stars won't ruin the image. As always CC and/or suggestions welcomed! Thanks, Rodd

    The new scope has arrived.... I have to say it’s a lovely bit of kit. Only a slight dink in the tube but otherwise flawless. Collimation was way off, but as @Lockie told me, it actually was easy to collimate. I set it up on the Skytee 2 and, with the tripod legs mostly collapsed, the eyepiece is at the perfect height, with the slow motion controls (the azimuth with a cable and the altitude with a knob) easily to hand without any stretching - seems very promising from a comfort point of view. The tube does hit the tripod legs (I’ve put padding on the legs to prevent damage to the ota) - I don’t know how annoying this is going to be, I’m expecting to work around it by just picking up the whole thing and moving round to the right areas of sky, this will also ensure the slo mo controls are always in the right position and easily to hand for high power viewing (I bought the scope specifically for doubles). I replaced the 6x30 finder with my Altair Astro 60mm finder to help finding those fainter doubles - this may end up being overkill. My only criticism is the focuser is quite stiff, but is nice and smooth - I can’t complain after the helical focuser of the Heritage 130P! I’ve yet to have first light with it, but I’m planning on posting my experiences with the scope over the next few months in this thread.

    Tommorrow is my b'day and with the huuuuge Coronado sale on now I decided to upgrade my Coronado 60mm solarmax 11 with bf10 to the 90mm solarmax 3 with bf15. This should be a big difference going to 90mm from 60 and saving about $1000 us is about $1300 then plus the taxes I save is closer to $1500 which is alot. I remember when I started in this hobby a 90mm Coronado would have been $8000 to $9000. Back then I'll probably sell the 60 when spring comes and most people start to think of the sun. Joejaguar

    TOA 130 with ASI 1600, 3nm Astrodon filter, 61 300 sec subs I would have liked to collect more data for the Ha channel, but that appears not to be possible in the foreseable future. Conditions were pretty bad throught the collection of this data--a full Moon (and poor seeing) for half of it, and very poor seeing for the other half. I obtained a smaller pixl guide cam in hopes to increase my guiding resolution in efforts to reduce my over FWHM values of my subs. But I have yet to use it--iy was -10C last night and I just could bring myself to fiddle with changing my guidecam--I don't think the Altair Astro 178 is the same diameter as the Lodestar 2x, so I will need to fiddle with connection tubes and cables and focus and probably grmelins in teh divers, etc. It wasa brutal night...so I stuck with the Lodestar. I am not sure in the 3 arsec/pix FWHM value of this image is due to poor seeing or too low of a guide cam resolution, but its the best I could manage (and I threw out almost half the subs). I probably should have software binned this data, but I want the image scale--in fact I had hoped to crop so that it was larger for viewing--but at this point the data can't support it.

    Nice!. I moon watched on the way into work.. which was on the M27 Motorway (AKA the car park) roughly crawling at 10 mph for 8 miles.. at 7am it looked stunning showing nice earth shine too.. Rob P.s the 10 mph on beloved M27 (Grrrrr) is a daily thing. seeing the Moon like today really helps pass the time.

    Friday 16/Jan – Sat 17 Jan 2020, UK The weather forecast had been changeable all day, but looked promising in spite of the considerable amounts of moisture in the air. I set my alarm for 10:30 pm and retired early, hoping to get a few hours observing in before the moon-rise just after 1am. The night was a lot clearer that I expected, so I set up my little Bresser 102s/600 & Exos2 in the back garden and visited a few favourites to check everything out. The Pleiades looked crisp and clear, M42 was a delight with the wings spreading across the field of view. The trapezium was very clear tonight. Surprised with the clarity, I swung over to M1, and there it was and small grey irregular fuzzy patch. Its not often I can see this in my small refractor. A UHC filter helped the dim the background slightly. My Messier list has several gaps from when I started it January 2019. Sirius was just off due south, shining brightly over the fence and the neighbours houses so I attempted some of the low elevation objects. I was very pleased to be able to add a umber of these clusters to my list: M41, M93, M46 and M47. The 15mm eyepiece worked well for all these of these. M79 eluded me, I needed a better view and to be set up earlier around 10pm. Monoceros was now riding high so I started a short tour of this faint constellation that I’ve not really looked at before. Beta Monoceros was not in the goto dictionary, so I went back to old-school star hopping to find it. A modest slightly egg shaped star was visible in the 15mm ep, so I popped in the 8mm and then the 5mm. When the atmosphere settled all 3 of the triple star system were resolved, B and C almost appearing to touch. The 5mm didn’t not really add to the experience apart from being able to see diffraction rings (they were round) and slightly blurry stars. The separation of these stars is about 7.4 and 2.8 arc sec. Since the Rayleigh limit of my refactor is approx. 1.35 arc sec, that was really very good and attests to the unusual (and unexpected) clarity of this evenings sky. NGC 2301 (the bird cluster): well it sort of looked like you might draw a bird in flight with 2 granular patches on my left side. NGC 2264 (Christmas tree cluster): A nice clear pine tree outline. No sign of any nebulosity. I will have to return with the camera. M50: a clear open cluster with a group of well resolved stars, more visible with averted vision. M48: a large cluster easily seen in the 25mm ep with a denser core and an L shaped pattern of brighter stars near the centre. It was now nearly 1 am and I still had a bit of time before the moon rose, so I swung around to Ursa Major near the zenith and grovelled near the floor to see M81 and M82 in the same view with the 25mm ep. The round and elongated shapes were clearly visible, but no detail. Seeking a challenge, I edged down to look for M97 (more grovelling near the floor looking up) not expecting to see anything. Surprise, there was a very faint round grey patch with what I call the 3 ‘locating stars’ to the side. A UHC filter and swapping in the 15mm ep (this is becoming my favourite EP) helped darken the sky to discern a faint fuzzy small tennis ball shape. No ‘eyes’ were visible. Again I was surprised how clear the evening had become as the temperature dropped towards zero and remembered how difficult it had been to find this a year ago even with the aid of a piggy back camera. Trying to make the most of the night, I covered the scope over and retired and dozed for a couple of hours before touring the early morning half (waning) moon terminator and sketching the sun setting over the craters and mountains. Thank you for reading – clear skies.

    Popped out for half an hour before clouds rolled in while getting dinner ready. Helios Stellar II 15x70's. Really nice views around Augria, some pleasing asterisms to be seen and beautiful contrasting colour. In and around Taurus too, Aldebaran a gorgeous red against an empty backdrop. Really lifts the spirit just to get a few minutes observing between this persistent cloud.

    Had some thoughts. There's more to this than the Astroberry Focuser and KStars/Ekos settings. I use a 28BYJ-48 5V Stepper Motor modified to work with an A4988 driver module which is driven from the RPi GPIO. The stepper drives the the focus sleeve with a quadrant gear and pinion on the motor. These are an earlier rig but the latest is similar with a different lens and dew shield. Different filter wheel too, as it happens.

    Several years ago I owned a nice 4" Astro Tech ED frac which eventually was also owned by @paulastro. I also owned a filter slide which held 5 - 1.25" filters. I did a review with a Neodymium filter, various coloured filters and no filter at all. I was able to quickly move the filter slide to obtain an almost instant comparison. I found the Neodymium gave the best view ( I think it was Jupiter) followed by no filter at all. I have no knowledge of the Contrast booster filter but I felt this report is quite interesting. https://www.firstlightoptics.com/reviews/baader-contrast-filters_US-ATT_review_0414.pdf

    It's generally an imager's obsession, John. In the early days the trick was to get it at all and then trying to get it's colour drove us all to distraction! It turns out to be a brownish colour. We think. I've never tried for it visually but why not? Useful pointers from Jetstream. Thanks. Olly

    I've just recieved an adjustment plate from Rowan, having had some chats about making alignment of dual scopes easier as referenced in the AZ100 owners thread. Some of these adjustment devices can be over engineered, and provide way too much adjustment. The requirement here is to provide a few degrees offset to compensate for any differences in scope optical axis or mounting hardware. It is normally altitude which needs adjustment, but I have also had instances where the scopes are out in azimuth. Dave at Rowan said they would try to provide adjustment in both directions, and that is just what has been achieved. What I recieved is a very neat plate, which sits between the alt axis and the saddle, exactly matching its profile so it looks very integrated. You attach the plate first, then attach the saddle to the plate. I understand that additional threaded holes are required in the saddle which are not there on any units supplied already, but Rowan will modify these free of charge if needed. They sent me an already modified saddle so I could try the system out. The back of the new plate has an aluminium block with two grub screws which act against an allen bolt which is fitted to the back of the saddle. This effectively pivots the saddle in the altitude axis. This arrangement is highlighted in red in one of the images. There are four additional grub screws, two each end which can be used to push either end of the saddle out in order to give an amount of azimuth adjustment. This is highlighted in blue in the same image. It is not easy to describe, but hopefully the pictures help explain and once you see it, the functions are obvious. I've yet to try this out but am sure it will give plenty of adjustment in both axes. I said to Dave that I had original envisaged a round plate. The actual plate looks very neat, and the benefit of the rectangular design is that it allows easy adjustment with the scopes fitted. So, yet another example of the responsiveness of the gents at Rowan, and also their ability to design simple but effective kit. I will update the thread when I've had a chance to use the new adjustment plate.

    And after the Meade bankruptcy fallout, Bresser appears to be JOC/Explore Scientific associated (owned?) while Celestron is owned by Synta and Meade is owned by Ningbo Sunny. Thus, this 14 year old discussion might not mean much in today's marketplace. Regardless, I think this thread would best be put back to rest:

    You were 100% right - guide lens misalignment was the root cause of that. I printed guider lens holder one more time with larger holding ring, put there guiding lens and aligned as good as I was able to, and now all works and looks fine. Stars are round in the FOV centre, so I am able to focus precisely. Star spectrum height is minimal. The star images at the FOV border are still distorted, but PHD handles with it very well. Reflections from brighter stars are still there, but that is not a big issue at all. Images from guider (Meade ACF 10" f/10 + ASI290MM).

    I'm pretty certain that it is the low altitude and poor seeing conditions that are causing the problems for all you poor folk up north. I wouldn't say it was easy, but I rarely failed to spot the pup whenever I tried last year with my 12 inch Dob, with Sirius being quite high in the sky down here. Apart from the glare of Sirius I found the diffraction spikes to be my main obstacle to overcome.

    That is a good point concerning using a large hood, this is something I haven't tried, I know that some on here with stray light situations use this method. I might take my hooded down jacket next time rather than my old down, non hooded, smock. Comfortable posture or seated position and becoming relaxed when at the eyepiece, is definitely beneficial, never forget my astro chair, only problem with it being black, I do from time to time stumble straight into it.

    You guys think it makes not sense because maybe not worthy to buy a coma corrector costing more than twice than the Chinese scope needed to be corrected? I have seen some folks with eyepiece collections costing many times more than the scopes they are used on. But again, I am not sure that this would be like buying the latest generation low noise cold camera to shot mag 14 carbon stars with your ShortTube 80. On the other hand, I have heard this 130PDS is used by some guys here for AP, and I guess some of them plug a CC into this scope for this application.. why wouldn't one plug a CC for visual then? I'm not interested now in obtaining an larger/more worthy Newtonian for the kind of observation I pursue at the moment (visual observation of brighter variable stars ). Probably some day I will get something like am 8" but I don't think that would happen any time soon. Maybe I should consider a fast refractor, but I would be struggling with CA instead of coma (not enough money for an APO). However I m not sure what would be worst (or less bad) for visual variables, coma of the fast reflector or false color (and field curvature) of a fast refractor.

    Well my first scope has been purchased, a great buy from Facebook Marketplace. It's a Skywatcher 200P with EQ5 mount. I'm enjoying building it up, the previous owner had not put the mount together correctly so could never had polar aligned it. Typical that theres been no clear skies for me since picking it up...

    I've gone back to the start with the Oii and Sii, I stacked them using the Ha as a reference so alignment stands up to papixel peep now. I remembered a technique for pulling out faint nebulosity that rescued many of my early images that saved the Oiii layer. I got more defined colours, then used the original Ha as a luminosity layer as it included all the O and S areas. Now, I'm starting to feel happy with this.

    Sketched early morning on 18 Jan 2020 The angle of the sun down the terminator made the Appenines light up like a white scar. So much to see and I don't usually look at the waning moon this early. Fascinating to see the shadows lengthen, whilst I sketched this, as the sun was setting over the mountains. Sketch is reversed L-R due to diagonal. Mixture of graphite pencils and charcoal pencils.

    You could try one of the 7.2 to 21.5mm zoom clones like the OpticStar, coupled with a Baader x2.25 Barlow might be a combo suited to the Heritage in terms of weight and cost? http://www.opticstar.com/Run/Astronomy/Astro-Accessories-Telescopes-Opticstar.asp?p=0_10_5_1_8_330 https://www.harrisontelescopes.co.uk/acatalog/baader-planetarium-2.25x-q-barlow-lens-1.25.html?gclid=EAIaIQobChMI4MjBnNiV5wIVgbTtCh2_WwaiEAQYAiABEgJoF_D_BwE

    Excellent report Neil! Seeing the HH is an accomplishment, congrats! If your obs partner is who I think it is you will be shown much, maybe ask her about seeing the sky "background" texture... a few of us see it on here. I can also say I see the HH in the VX10 no filter and repeated viewing makes it so much easier. Again congrats!
