  3. I wasn't very impressed with my first attempt at IC1805 with my colour Trius SX26C camera (see my gallery if your interested), I decided it was a bit "flat". So, here's my second attempt, this time with H alpha on a different camera (Trius SX814) and a bit more post processing knowledge. Since the Ha is strong, I decided to blend via PS screen a small proportion of this into both the Luminescence and RED channels. I quite like the variety of star colours within the nebula, so I decided not to push them into the background too much. The final LRGB +Ha image represents about 10

  4. So, you can blame me for any poor weather in Beds/Herts/Bucks area!!! Just ordered an Esprit 100ED to live in the observatory! Spent hours researching, checking FoV, CCD suitability and bombarding people with questions (Thanks FLO, Steve!) Dead excited now!!! COME ON SKYWATCHER - IS IT HERE YET???!

  6. Good morning the fine people of sgl.... as a good handful of you know I'm rather new to astronomy.... unfortunatly for the past two weeks my health hasn't been too good so on them brief nights between being cloudy and clear I haven't been able to enjoy viewing with my scope. the past few days I haven't been hitting my pillow until 9am and I have been viewing Jupiter out the window wishing I was well enough to go out to the garden and take a more magnified peek. I'm pleased to say this morning was the morning! my first view of Jupiter and its moons!!! i didn't need

  9. This thread was not posted to start a rift or a pasting for either discipline, honest. Being fair I don't think it has. What it has shown is that these are multiple strands of the astronomy hobby, all valid, all enjoyable. No one is right or wrong, they are astronomers with differing interests, just like all things in life.

  10. Well, here's early sight of my integration of the Ha images. I only managed 34 x 30s and 22 x 60s, all taken at 300 gain, 50 offset and -20C. I haven't inspected them, rejected any images, or applied any calibration. This is uncropped and only stretched with levels and curves. I have to say, Ha data is so much cleaner to work with than LRGB! I'll be taking flats tomorrow and doing a proper integration of this, and my LRGB data (not that I got much before it went behind the steam vent). I also took a quick peek at M81 and it's a breath taking galaxy (but that one really does need calibrating!).

  11. Hi Well it’s been almost 6 years since I joined as a member of this community and this is my 1000th post - not a lot in 6 years really but I hope that my contribution has helped, especially here in the Video Astronomy section. I still think of this section as my baby, although there are those who are now much more active than me. Back in 2011 there was no Video Astronomy section and at the time the Mods did not think that there was enough demand for one so Video Astronomy or Electronically Assisted Astronomy got lumped in with the Astro Photographers. So I set up a social group

  13. Had a bash at some minor planet spotting on Friday night/Saturday morning. Pointed the scope at a fairly nondescript bit of space between Gemini and Cancer and started taking pictures. The star in the middle of the field is (I believe!) asteroid 4 Vesta at a distance of some 227 million kilometres. I took five frames over a period of twenty-five minutes before the clouds came over to see what I was doing, but even over this short a period, you can see some elongation of Vesta as it drifts relative to the fixed background stars. Interesting way to spend some time since the weather wa

  14. Hi all, I know this has been done to death but just had to do it again. M 42 was the first DSO i ever did when I started this game and I blame it for all the expense and frustration! Anyway its been 2 years since I last did it with the poor seeing here its the only thing that I could image so here it is! 12 x 4 mins, 3 x 2 mins, 12 x 1 mins and a little bit from 2 years ago all at 800 iso. And a close up! Hints and tips welcome.

  15. Well this is probably going to be the most disappointing first light report you ever read but I'm writing it mainly to demonstrate to beginners that this wonderful hobby of ours can be frustrating and hard work. A break in the clouds last night meant I could get first light on my newly acquired Meade 10" SCT which I've lovingly fitted out with a 2" Moonlite focuser and a nice SW 32mm 2" EP for lowish (by SCT standards at least) viewing. Stat celestial delights awaited me. After a half hour fight just trying to mount the damned thing I went through my mounts alignment process. Here

  16. The first thing I ever wanted to take an image of was Andromeda. Several years later - OK, only three but still.... - a goodly amount of money invested, a major disaster rendering half of my gear defunct, and tada!!!!.... this monstrosity 50 x 60x ISO 800, flats and bias applied (Nebulosity 4). Processing in N4. Skywatcher ED80, Canon 600D, unguided. noisy, badly processed, noise, stretch within inches of it's life.

  17. From the album: Ken's images

    This is my first attempt at taking and using narrowband within my LRGB images. This builds on a little LRGB data already taken (version) combined with additional Ha and RGB data taken last night. There is still very little data here as I have a limited window of visibility before it goes behind the house. Using the Skywatcher Esprit 80 with the ZWO ASI1600MM-C, the ZWO LRGB filters and the Astrodon 3nm Ha filter. All images taken at -20C, 300 gain and 50 offset. During processing I discarded all L data as it was weak in comparison to the Ha data, even when blended. I have also blende

  18. What a lot of the naive perpetrators don't seem to know is that the experienced imagers do know that they are doing it. Since this is a good, life affirming and friendly community it is often best to say nothing and let them get on with it. They are not breaking our telescopes, after all. We do e-mail each other, though. I could give plenty of examples, such as Cigar galaxies passed off as LRGB when anyone with a month's experience knows it's an HaLRGB image - and so on. But, should any of these characters be reading this, you might be surprised by how well known you are! I don't sell im

  20. Now in it's 5th year This event is a non profit event and in previous years all profits went towards us working with young people disengaged from education. This year all profits will go towards astronomy outreach in the North West of England and the profits will be divided up between all clubs and societies who participate at the festival by way of a stall/outreach.

  21. So, at the simple click of the wrong button, I have just captured an exquisitely well tracked and centred 1200 second image of my focus star - Doh! On a more positive note, it gave me an opportunity to check out the flatness of the field of view with my larger (APS C) imaging sensor and I have no complaints there: - Esprit 150 ED/SXVF-M25C Field Curvature Plot

  22. Another good early evening session before a meal and a relaxing evening indoors. Love this time of year! I haven't really gone for many doubles, tending to go for clusters by preference, but Orion was peeping up over some houses in the SE, so I went for his key components. GPS and one-star alignment on Aldebaran worked a treat, putting all targets almost dead centre. RIGEL: Low at first, misty conditions, and a heating flue in a roof underneath, so it was fuzzy and couldn't be split. Later however at x113 and with AV, I spotted a close, faint companion star.

  23. Leslie.C.Peltier was an avid amateur observer for the AAVSO and mentioned many of his reports in his book starlight nights. He contributed for many years with his reports (more than 100,000 of them) using a 2", 6" and 12" refractor. A true observing giant and one that is remembered with an award. He also had other interests one of which was photography.

  28. There’s room for everyone in the hobby and make of it what you will. Do whatever makes you happy or happiest, that might be more than one aspect. Technically although I am strictly visual, I do try to sketch the new things that I see, as well as planets and solar features (soon the moon as well if I can) and then compare what I think I was seeing. Without the imagers, it would be more difficult to make online comparisons and therefore I am grateful to them for taking the trouble to use their skills. In sketching, I suppose I am ‘imaging’ albeit in a very basic way and undoubtedly wit

  29. Yes the DC does take 2" eyepieces, but the 2" adapter is needed. When I ordered mine, I spoke with the vendor who very kindly included the Tak 2" adapter and a Tak Mewlon dovetail plate in with the package free of charge. I've rarely used the 2" fit option though, as I generally use a 1.25" Pentax 20mm XW as my lowest power. Mike

  31. Sounds like an excellent session Nathan, glad you got good views. Don't ever think of Jupiter as something to be ticked off the list. For many of us it is a regular companion over the years, and shows an ever changing view. The Great Red Spot can be seen moving across the surface when it is in view, and more belts, festoons and barges (darker spots) can be seen. As for the Galilean moons, they are always in different positions, and regularly go into eclipse behind or transit the surface of Jupiter. You can even see the shadows cast by the moons on the surface. It's an amazing planet

  32. Personally I'd firstly be investigating the capabilities of your current set-up. The shot you posted is not at all shabby for 10 secs. You have a capable tracking mount so why not try tracking and stacking to see what can be achieved with the gear you already have.

  33. Umar, probably not the best plan to get lots of eyepieces just 1mm apart. 10mm in your scope gives 200x 9mm in your scope gives 222x 8mm gives 250x Jumps of 50x are very worthwhile, but a small jump of x22 will be hardly noticeable at the eyepiece. so, buying a 10 and 8 would make more sense. Skip the 9mm would be my advice. Alan

  34. I have the MAK 150 and ED80. Both really portable and sit well on the HEQ5. The ED80 is pin sharp with no colour fringing at all. The first view of Saturn I ever had was on the ED80 and although small in the FoV the fine detail was actually outstanding. The MAK is great on planets and the moon (the latter of which it excels). However, although the CO is smaller that SCTs it still softens the image and on stars i.e. binary doubles etc you can expect a bit of smearing (smudging). To be honest I am impressed more with the Globular's the MAK has shown me. In these types of DSOs it hasn'

  35. Hi Before buying any software or any more equipment, I would recommend getting hold of 'Making Every Photon Count' - a book written by Steve Richards - @steppenwolf on this forum. It is available from FLO. This will answer most (probably all) of your questions. There is quite a bit involved in astrophotography, so much so that Steve had to write a book to explain it to beginners like me. You are clearly enthusiastic. I don't blame you - it can be a rewarding pastime. It can also be very frustrating. Your Flextube GOTO has a long focal length - this is challenging. You will pro

I combined the video with two pictures of the Orion nebula and Rosette, taken through my TS 80mm APO refractor. Enjoy the view :-). https://youtu.be/c9bRlwL4ndQ Wido.

  41. At last - today a chance to test the QHY 5-11m camera I swapped with Bern from Modern Astronomy at Kelling in October last year. I had been plagued with Newtons rings and even a tilt adaptor at extreme angles wouldn't cure them. I tested a few from Bern and finally selected one that minimised the effect, but only today had a chance to test it - complete with my new Moonlite focuser for the LS50. After a bit of messing I found the spot where the rings weren't, the whole disc was in focus and I was finally able to take a mono image of the sun's full disc. It's not a great image as I ha

  42. I had yet another great weekend at Tähtikallio observatory in Finland. First night was clear until sunrise washed out stars. Second night was good until clouds rolled in few hours after sunset. I had a ton of airglow on first night, although seeing was excellent. This limited my observable objects to magnitude 14-15. I usually can see even mag 16 objects with our scope, 36" f/3.5 Astrofox folded Newtonian. Left side dome is for photographic purposes only, housing Alluna 16" RCOS. On the right is dome for Astrofox which barely fits inside the observatory. Shortly after I took that photograph

  44. I enjoy the ultra wide field of view, which applies to each of my three manually driven scopes. I also enjoy 72 wide and 50 degree plossl AFOV when these focal length / optical design are applicably required. The main feature which applies in each case is comfortable eye relief and eye placement.

  46. I'm sort of going in the opposite direction! I have a set of lightweight eyepieces, BGOs, Nag Zoom, 24mm Panoptic and a x2.5 PM which fit in a very small case and don't affect the balance much on a Giro WR. The Delites might well be worth a look in future though (or XWs) I do like a widefield view though, so you may have seen the 20 and 30mm ES and the Burgess Optical 40mm I've got not. Need a dark site for these to really shine though, although 20mm is fine at home. I have a 2" Everbrite for these, or the T2 BBHS with 2" fittings.

  47. Stu - you have to get the optional Tak adapter to fit a 2" diagonal to the DC. I'm using a Baader prism and clicklocks so have both options, but am pretty much going to stick with 1.25" eps. Only problem with the DC is that it makes you reassess your eyepieces. Am slowly getting a lightweight set together - have a Panoptic 24 and Delite 7, on the lookout for a couple more. Either Nagler 16mm or Panoptic 15mm and Delite 4mm or Nagler 3.5mm would be ideal. Depends if anything comes up in the classifieds. But very tempted to go for ES 16mm and 4.7mm - astrofest is looming at the start of Fe

  50. When I make a visual observation, I know that very few people, or more likely nobody, is looking at that object at that moment, especially if it's some small, faint, unsung galaxy that imagers will never bother with as they fall over themselves to image M33 again and again and again. At that instant, no one else is looking at it. My view of that object is MY view. An image cannot be perfectly replicated, but close enough that no one can see the difference. My observation will never be replicated because it's what I saw with my eyes at that moment. For me, it's not, to quote goodricke1 'photons
