    I needed something big and bright to image last night with a 50% moon so this seemed the obvious choice. Probably not the best night to try and chase the feint nebulosity surrounding Andromeda but i think i caught a little. Takahashi Epsilon 130d Zwo Asi 071 pro Osc 130 * 150 second subs gain 50 Az Eq6.

    M101 has been challenging to say the least, particularly because of the high LP around here causing my luminance frames to have all sorts of funky gradients and banding and also issues with colour balance. I think I'm relatively happy with this result for now, although I'll definitely aim for more data (at least 10 hours of luminance) to get better SNR, and maybe add some Ha.

    Hello all,as a totak noobie and not just green behind thr ears but all over ?. Ive had my first scope for 7 days now a 2nd hand skywatcher 200p dob, i only have the 2 eye pieces that came with it. I decided to go out in the communal garden again tonight asbthe sky looked good,i got out at 8.30 to give the scope time to cool down and get muself comfy. It was a lovely fairly clear night.And for the first time i managed to get Saturn in my finder scope after finally sorting out its alignment on friday, i started off with tue 25mm eyepiece saturn was tiny but i could cleary make out the rings i was gob smacked so happy and excited i quickly fumbled for the 10mm eye piece and slipped that in a slight adjustment of the scope and saturn was slightly larger and the rings alot more visible wow wow wow i am still on cloud nine it was amazing,i looked at it and followed it for what felt like half an hour.my wife bought me a cup of tea and she had a look to and a couple of my neighbours were very impressed. I then waited for mars to move round and quickly focused on it and i started with the 25mm and then moved on to the 10mm. Before tonight i wasnt very impressed with the 10mm but it did a good job tonight. Im still buzzing and im off to bed now. Just thought i would share with all you wonderful people. Many thanks and best wishes From me Dave ?

    From last night... 15 X 12.5 min, iso 400, DSS and PS. I used a CLS filter that enabled long exposures but it also (helped by high cloud) prevented any colour, especially those blues. Perhaps I'll try very low iso (100) next time without the CLS and see how long I can get to without over exposing.

    After the opposition the diameter diameter display is quite fast as well as the phase increase. In this photo we can see Olympus Mons as an orange spot near 01:00 hs and at exactly 9:00 there is a clear line that at first I thought it was a defect in the photograph but then when I went to check I realized it was Aeolis Mensae which has a network of Valleys in that location. It is interesting to note how some formations changed their appearance due to the storm. https://www.astrobin.com/364789/0/?nc=user

    My first attempt at imaging and processing a dark nebula, and probably my first really good run at the Atik 383L+ in some proper darkness. I imaged last night from 10pm so I had to content with the moon after midnight. I haven't used darks because I hadn't built a library of darks past 600s. Currently doing them now, takes a while at only 4 per hour! 18 x 900s L with Atik 383L+ 38 x 300s RBG with Canon 40d ED80 FF0.85x EQ6 It was nice to see some detail come through. Please feel free to offer advice. Processing with DSS and PS. I hadn't really a clue on how to process this, and it does look a bit harsh. The DSLR image was quite horrible too ?

    Was just mooching on FLO and noticed the BST Starguiders have an offer for multiple purchases. So I did the only thing that made sense, I bought the full range! I'm blaming you lot on here for constantly saying they're good value for money and worth having. ? Going to need a new case for them all now, curses.......

    Astrodarkness is getting back up here. This is the first decently large data set I got with my new ASI071mcc pro, almost 6 hours over the last two nights, but with a half moon. First night I managed to get 29 x 3 min of RGB data (gain 150 offset 20) and the second night I put on a Ha fliter and got 52 x 5 min Ha data (gain 200 offset 20). So Ha through a OSC.... yes I know it is not optimal but it has 16 megapixels and is quite sensitive with low noise and what do you do if they do not sell APS-C sized mono CMOS cameras (yet). Chip at -15°C. Stacked and calibrated in PI. Processed in PS. This is a fairly faint object so obviously more data would be nice. But I think it is a very promising camera. Comments and suggestions most welcome!

    Hello All, Tonight and hopefully tomorrow night I was planing to see Phobos and/or Deimos. I have two windows of opportunity tonight, at 20:50-21:20 AEST and 00:30-01:00 to see Phobos and tomorrow around 20:00 to see both Phobos and Deimos. I covered half of my Ethos eyepiece opening with electrical tape to put Mars behind and look for Phobos. The shield worked a charm, but still Phobos did not pop into view at all. Visually I was unsuccessful to see Phobos tonight but imaging at 1/15th second exposure I might have not only caught Phobos, but also Deimos coming around from the glare of Mars. The attached image was exposed one for Phobos, 1/15th sec with gain set at max gain and for Mars I exposed a 1/313th sec @ 60fps and no gain than combine both in photoshop. I'm hoping to give it another go at 00:30-01:00. Clear skies, MG

    On Friday last I managed To get 25 x 4 mins subs with my new camera. I was meant to be adding Oiii last night but have picked up man flue so was told not to go out on the pain of death! Here is the results so far, calibrated with darks and flats all at -15. Still seem to be getting a lot of noise but am pleased with the result so far. Hopefully all being well ill add the other filters and get some colour in the images as well as me! lol Framing is a bit poor but my excuse is I want it Now! any hints and tips welcome.

    Hi Dave, Very well done getting those two planets in your first week with the scope and for your excellent report too, thanks for sharing the experience on here. Good on you to share those views with your neighbours (and wife of course); I also had neighbours with their 6 year old daughter and the mum's parents round to look at Saturn last night. The daughter was meant to be in bed, but mum relented (well it is still school hols) and they all had a great time ?. I almost get as big a kick out of sharing the views with others as seeing them myself. Cheers, Geof

    Its absoloutly real! Planet 9 was discovered a lifetime ago. It's just the political paper pushers trying to justify their pointless existance who are in denial. I've attached a quick pic through my i-phone and 30mm finder as evidence, and a more detailed close-up through my 100mm frac. ? IT'S COLD OUT THERE!

    Hi Guys, I thought I would share with you the spoils of last nights observing, it was a very clear and calm night here in Suffolk and I took the opportunity to travel a few miles out from Stowmarket, to and old second world war airfield, were there is next to no light pollution, as a result I thought I would try to capture the Bubble Nebula. This Deep Sky Object has always been a difficult one for me, never really managed to pull it off, however with the aid of my Skywatcher 100 ED Pro Esprit Telescope complete with my Sony A7Rii Camera, atop my Skywatcher NEQ6 mount, using my Skywatcher 50ED Guide Scope, complete with Altair Astro ASI130mm (mono) guide camera and PHD2 Software of course, I was able to capture the picture below. I have to say I am very happy. The images is made up of 10 x 120s frames at ISO5000, no darks, flats or bias frames were used, stacked in Photoshop via the Mean function, levels and curves adjusted to suit. The Sony A7rii camera seems to manage noise very well, even at 5000 ISO. Welcome comments / discussion. Many thanks Jamie

    Finally a beautiful night that I didn't have to work! I stepped out of the house and wow! I've never seen my Bortle 4 skies look so nice! Milky Way stretched all the way from the south to North past Cassiopeia. More stars than I've ever seen at this location in the 3 years I've lived here! Even the Andromeda Galaxy was naked eye with averted vision. Just a beautiful sky! I take Copernicus (8" newt) out and set up for the night. Now when I set up I set up! There are marks where I place the mounts legs to quicken my polar alignment. A comfortable chair in case I need one. A small table that holds my EP case and clipboard with log sheets. I even brought Kepler (10x50s) out. I tend to set up for the long haul. Doesn't take long to set up really. Maybe 10 minutes. I had planned my night with a load of targets. M72, m73, Neptune, Uranus, 21p, Juno, Pleiades. I was ready to go! First on my list...m72. I dial in the coordinates and ..... Nothing. Did a slight search and saw a barely perceptible smudge. Averted vision revealed the 4 main stars of m73. Hmmmm something isn't right. This should be quite obvious in the scope with a magnitude of 9.14. I start hop to the location for m72 and search.....and search.......and search until.... What was that? Something occasionally stellaring where it should be...yep that's it. This too should of been obvious. Now I'm getting concerned. I turn to Neptune. This turned into another long search. I found my land marks that lead me to it's location. But where was it? It's not there! Oh wait....what was that? An almost nearly eye squinting stellaring object again! Grrrrr....curses! I've seen Neptune before, so I know Copernicus can handle it. What is the deal?!? My next target, Uranus, won't be in a good position for a bit, so I pick up Kepler and start just scanning and enjoying some gorgeous star fields. I figure I would scan for 21P to see if it's visible in the binos. Nope, just stars. Finally I go back to Copernicus to look for Uranus. Well, once again, no luck! I think to myself "Well fiddlesticks! What is going on tonight!" As I'm thinking this, I notice the sweat pouring down my forehead and my shirt is soaked. Grrrrr, it's the humidity! That's what is killing my viewing session! Tonight's humidity is 81%! The universe was being a big tease!!!! How else could I explain the gorgeous skies and the lousy views! Oh, did I mention all the cars that kept going by? So many cars came thru during my session that I was getting aggravated. Finally I realized I wasn't meant to observe tonight, so I packed everything up. I figured it was the best thing to do. Especially since I hadn't slept since yesterday. Robby is a grumpy boy when he's sleepy sleep . I should of figured earlier that I was getting cantankerous when I hollered at one of the cars "Shouldn't all you people be in bed so you can work in the morning, or does this town just have a ton of slackers!!!!" Well the moral of the story is just because the sky looks great doesn't mean its scope friendly. Oh well, tomorrow night is another night and the humidity is only supposed to be 61%! Goodnight all, Rob AKA the cantankerous one.

    I think the best advice in this thread is to try what comes with the scope a few times before jumping into alternative / additional acessories. There are literally dozens of great things you can add to the scope but a bit of experience under your belt will help a lot to sort out which ones will deliver the best gains for you.

    Hello again, this is the scope I think I will get. A few people on here have mentioned the 127 Maks and I think it will have more chance of getting used as it seems very portable and easy to store when not in use. I know it’s not great for DSOs but I will have fun finding the smudges. https://www.harrisontelescopes.co.uk/acatalog/skywatcher-skymax-127-azgti-telescope.html#tab-3 If im making a mistake or you think there is a better scope for the money please let me know. I’m not buying until December so no rush. Thanks again for your valued help and advice.

    Thanks so much everyone,you guys are amazing and im genuinely touched by the encouragement and advice and tips. Ive been a good boy and resisted buying cheap eye pieces from ebay.decided if ic can get mid range price or good 2nd hand eye pieces thats the way im going to go.But im not going to rush,i still have to get a chesire and turn left at orion. Hoping to get a ppi pay out fingers crossed. I was telling everyone at work today about seeing saturn most of them not impressed but the odd person was quite interested. Yep last night was amazing for me on a personal level.Everyrhing is slowly coming together. Once again thank you all so much ?

    Can't help but see so much misunderstanding here , perhaps the result of too many an eager TV producer with CGI overuse (Chris - aka McCavity may well throw brick bats at Brian Cox) - there is no confusion within the scientific community. The "Big Bang" theory is the populist name for the conditions which cosmologists and particle physics regard as defining the earliest state of the universe. If you look no further than that catchy name then confusion and misinterpretation will certainly prevail. As for evidence, the "Big Bang" / the Lambda CDM model (Standard model) is imho the best supported and most complete model of modern Physics which describe the nature of universe with a remarkable degree of conformity. From the correlation of predicted / measured abundance of light elements, the fine structure of the CMB and recessional velocity of galaxies v distance (Hubble's law), the evidence to support Lemaitre's "primeval atom" model is nothing but compelling. Forget Hoyel's pejorative "Big Bang" - he used that tag with purpose to ridicule a theory he did not support and the confusion he caused appears to have lingered. Lamaitre's model placed the origin of the universe at a single particular state which would later be termed a singularity. There was no "bang" rather something much more exotic "inflation" or exponential expansion of space. Inflation (theorised in the late 1970) explains the large scale structure that is seen in the universe (structure which arose from quantum fluctuations in the pre inflationary period). Evidence for inflation is again well supported: the isotropic observation of our universe (it looks the same no matter where we look), the even distribution of the CMB and the lack of magnetic monopoles (at least not detected ). This utterly bizarre and little understood inflationary period is estimated to have occurred at t minus 1 x 10 ^-33 s following the singularity pitching up and announcing its arrival. It lasted for approximately 1 x 10^-36 s (supported by data drawn from particle collisions at the likes of CERN ) . And therein is the "Big Bang" killer - there was no bang - rather it was a strange "inflation" where the universe went from existence as a singularity to, well I've read different accounts ranging from the size of an orange to a basket ball - but no bang , no explosion. Ok now we turn to matter. Matter was not created at the "Big Bang" - hey let's now call it "the very short and not very well understood period of inflation" - not as catchy as Hoyel's pejorative Big Bang but more accurate Anyway, the universe, while at a state of singularity and during inflation was simply too hot for matter to form - more correctly for it to exist in its baryonic form (atoms and stuff) - it was simply present as energy. Visit CERN and they will tell you (supported by their collision data) that it took some 400, 000 years until the universe had cooled (energy dissipated) until normal (baryonic) matter could form (electrons captured by the nucleus). So, what do we have - no shattering or scattering of matter at the start of the universe in some kind of cosmic fire work but rather " the very short period and not very well understood period of inflation". Oh and a theory that remains intact, and fits remarkably well observations made of the present state of the universe Jim

    The problem with winter viewing is if it a beautiful clear night you tend to have a lot of high level atmospheric turbulence that can limit seeing. But with that being said, I've had my best sessions in the winter. Usually after a storm front passes through ,if you look at the sky, you'll notice it clear with a very slight hazy look. That's when it's time to get the scope up. The haze is because of a lack of turbulence. The seeing is usually phenomenal and the very slight haze tends to not really affect the scopes ability. Just dress warm and make sure to let the scope cool down enough. Hope this helps. Rob

    I've recently signed up to the Slooh.com astronomer package and while you don't have the control and the option to capture any really long subs that you get with iTelescope, you do have potentially 20 hours per day imaging time, unlimited 'missions' (slots) and they've got some pretty decent gear. Their big scope on El Teide doesn't do well in the wind, so you lose a fair amount of subs but what you do get out of it is pretty good. For 20 quid a month you can't go wrong. While I'm waiting for the big scope to provide some data for a project I'm working on I decided to fill in with this one captured on one of their other rigs. It's 23 mins in 15x50s subs with their 11" Rowe Ackerman Schmidt Astrograph, details below. I did 3 versions - colour, mono and inverted. I stretched the mono and invert a fair bit more than the colour for tail detail. There's vignetting and flicker but for single subs I'm pretty happy. I might run this again and stack pairs to give me a little more processing leeway.

    Since May I have been imaging around the constellation of Cepheus to capture some of the many Sharpless objects and dark dust areas there with my modified Canon DSLR, and my Star Adventurer mount and CG-5 mount. Two clear nights in the past week finally allowed the completion of the project, a 7-pane mosaic stretching from the nebulosity near Mu Cepheii to NGC 7822. To Stephen O’Meara the visual association of IC 1396 and open cluster Trumpler 37 close by Mu Cepheii resembled, “... a large blossoming flower in a moonlit garden covered in frost.” (page 521 of ‘Hidden Treasures’). How very apt. By combining several other Ha images and capturing a wider area reveals not just this flower but the stem, leaves and roots as if rendered in an impressionist painting of over 19 degrees of night sky. Each pane of the mosaic comprised two hours worth of 300 second individual exposures at ISO 400 taken with the modified Canon 700D DSLR, 12nm clip-in Astronomik Ha filter and 135mm Samyang lens at f/2. The light frames were stacked with temperature matching dark frames and with master flat and bias frames from my library. Stacking was done using Deep Sky Stacker and the image further processed with StarTools. Microsoft ICE was then used to stitch the panes together. I also post an image with tones inverted which personally think emphasises the plant analogy best. I hope some members like the mosaic images of the area. Cheers, Steve

    Well decided on going out tonight for a quick scan of the night sky but our dog put an end to that she found a "Herrison" hedgehog and her offsprings in the garden and proceeded to bark to kingdom come(this is my house get out). not good for the neighbours Damn and double Damn. I cannot stop the dog from coming out as she follows me everywhere I go and I have to leave the patio doors open to get to the back garden. wildlife wins tonight not the clouds.... that's life anyone had a similar problem
