  2. This is my first image in over a year, I've nearly forgotten how to do them. This was taken over nine frustrating nights in January and February, some nights only one sub was kept! There was constant cloud fronts passing through, and as soon as I gave up and de-rigged the kit, the sky would clear, very frustrating. So anyway, finally got down to processing it, PI was not playing ball, (I had to get the book out I was so rusty). I kept getting black flecks, especially after sharpening, so in the end I gave up and manually removed them is PS. Kit was my usual, FSQ106 at 380m

  4. Hey ya'll! Hope everyone's having a good week! I started working on Sarah's Galaxy (NGC 3628) last week as my next project. I think I may finish up here with luminance data and move on to RGB on the next clear night. The image below consists of 17.5 hours via 300s subs. The noise is really starting to die down after applying calibration frames, almost to the point where the extra 5 or so hours I WOULD get may not be worth it (thoughts? Still getting used to this camera). Anyways, I plan on getting about 4 hours RGB each totaling 29.5 hrs. iOptron CEM60 Astro-Tech 8RC ASI160

  5. I have one slightly odd corner but I can live with it. Imaging at f2 in narrowband with very bad LP really saved my AP. A hardish one for me was the Spaghetti, only 14x900secs with the moon at 90 degrees and footie floodlights blazing. Never thought I could ever get this one, I want to revisit when it's much darker one evening.

  10. Hi All Well Olly has already posted the First Light Dual TEC, but here is my attempt. Yes I burnt out the core, the background is noisy (And by posting it has got way noisier), its probably over-saturated but I enjoyed playing with this one. I love spiral galaxies, and at 1m imaging you can get close to those spiral arms despite their small size. Tom

  11. Hi, Inspired by Forum Member Xiga, after seeing his fine image of M101 on 22 March 2019, I just couldn't wait to get an image of the Pinwheel Galaxy. My image was taken on 27/03/2019 with my Orion ED80 Refractor and Canon 450D, on my NEQ6Pro mount. ( As usual, at present, my images don't have enough hours put into them yet, because I am still figuring out how to plate-solve with APT ! Once I get plate-solving under my belt, I will start to get more data, hours wise, into my images ). My image below is approx 1 hours worth of light subs, composed of a mixture of mainly 70 sec ligh

  12. Finally I have a Clave telescope to go with my collection of Clave eyepieces. It's a 80mm objective with a 1208mm focal length making it F15. It has a new aluminium tube, fully flocked with at least 5 baffles from what I can see. I have yet to use it due to poor weather but cannot wait to see if my Clave eyepieces work well with it. Clave never made telescopes only objectives so the few scopes that are around are all the do it yourself variety. I need to sort out a way to mount my red dot finder without damaging the tube, but i do have an idea for that. And it needs an handle be

  14. Mars this year gave a real Show. . . That being so, I could not fail to register it. This composition, made with an approximate interval of 10 to 15 days between the photos, starts on July 31 when the planet reaches the largest apparent diameter (24.3 "arc) and ends on December 5 when it was with only 8,9 "of arc. Three things are very evident in such a work: first, the marked reduction of the diameter as the planet departs; secondly, the phase decrease as it approaches the quadrature and, finally, the marked reduction of the South Polar Calota, which, in the last photo, is reduced to a

  15. Hello , As some might know, FLO are very kindly loaning me a series of beginner telescopes to review (one every two months if all goes well!)...what a wonderful thing! Anyway, the first scope arrived last week, and I've decided to try and do two reviews for each scope; an unboxing, setup & initial thoughts review, and a more long term in use review, with pros and cons for the beginner and the more experienced astronomer. A big thank you to FLO and Coffee Link to telescope below: https://www.firstlightoptics.com/sky-watcher-az-pronto/sky-watcher-skymax-102-az-pronto.h

  16. Way back last year I was approached by Professor John Brown OBE - Astronomer Royal for Scotland - asking permission to use some of my astro-images in a book he was writing. The book went to press yesterday and there is an article about it and a review of it in the 'Scotland on Sunday' newspaper this coming Sunday. Anything that puts astro-imaging in front of the public has to be a good thing !! I guess my images will be used to demonstrate all the mistakes that can be made ;-)

  17. Cheers. My small 80ed installed on a eq5 was my companion for 10 hours passed in the backyard during many clear sky night. This is the result my asi1600mm helped me to bring back from the sky. I'm looking around for any suggestion or whatever constructive criticism to get better result. Will you help me? 5+5 hours ha and o3, light of 300" plus dark and flat. Pixinsight and Photoshop as software for elaboration while Apt helped me during the session. Clear sky!

  18. The constellation we know as Orion has significance in many cultures across the globe. For the Maya, Orion is considered the region of creation. The stars Alnitak, Saiph and Rigel form the three hearth stones (prevalent in traditional Mayan homes), and the Orion Nebula (M42) represents the cosmic fire. An apt analogy for this hotbed of stellar creation, one of the closer nebulae to us, a mere 1350 light years away!

  19. Thank you! Don't forget the Epsilon-180ED produces very tiny star images. In the image below I've combined the spot diagrams of the Epsilon-180ED with the FSQ-106 (fluorite version) and scaled them to the equal resolution. Here's a single frame (300s) straight from the camera without any processing (That is: JPEG preview / gamma stretch in the camera). Focusing was done on the LCD screen of the camera (using a magnifying glass) and a Bahtinov mask in front of the aperture. Post-processing took less than 10 minutes.

  22. Here's a link to an article and a list of 12 quasars that are currently visible. I just observed 3C-273 for the first time about a week ago and was looking for others to find then this just comes out. What luck. Seven of them are mag 14.1 or under so these seem to be do-able. The furthest is HS 0624+6907 mag 14.0 in Camelopardalis 4.56 billion light years. That's probably the farthest thing I'll ever be able to see with my Z10. The light from that is from back when our solar system was forming. Pretty amazing. Anyway, here's the link https://www.skyandtelescope.com/observ

  23. I think that the DSLR did more then I expected here. Haze was a little over the limit which made me struggle with the background. A clear sky is only in my dreams. The light gathering pixels still did a fair amount of work. The CLS filter does what it is supposed to do. Yes well here it is :) 13x100, 45x360 ISO 800

  24. So I caught myself in not knowing when I last had out the scope so I went over to look at my sketches and it suddenly hit me. I haven't even posted them on here That's when I decided that I wanted to share it but not only here. Also for other people who stumbles across one of my videos on youtube, so I published a new page on my website with all my sketches. I hope you like it but keep in mind that they were all done with nothing more than a pencil and and eraser. https://myastronomyjourney.wordpress.com/my-astronomy-sketches/

  25. Hi guys, This is the first lights of my ASA 12"N f/3.62 (purchased in 2007) with my Moravian G4-16000 CCD camera using one KAF-16803 chip of 36mm x 36mm (4K x 4K). The adjustments, collimation, ASA OK3-Z pression screws, asked a lot of attention. For a precise collimation, i use the CATSEYE XL & XLKP kit. This is the first 3hrs of exposures taken the last weekend in one night. The second night was too windy unfortunately.

  26. Relatives all left a little earlier than expected today, so I managed to get out to the observatory for a short while. Had a sweep up, then made a load more mess cutting the lower section of ply for the warm room side of the internal wall and cutting a bit more insulation for the top half of the same wall. I could have done more, but it's been a long day. I'm hoping that tomorrow I can completely finish lining the warm room walls, finish off the insulation in the internal wall and get most of the remainder of the scope room side of the wall lined, at which point I'll be ready to start t

  28. Inherited a C6 from my brother, who got the astro-bug a decade or so ago but didn't like the late nights (? ) . Knowing it was a decent piece of kit, it rekindled my dormant interest in astronomy and so nowadays I have a soft spot for it, and trundle it out on occaison. It is a very veratile scope. Solar, lunar, planetary and yes, a bit of Deep sky. The M81 image was subject to a passing shower, one of those that didn't show up on the weather radar. Only a very light speckling on the objective, but alas it smears out all the point sources. Oh well, could have been diffr

  32. I knew my local dark site would be opening up last night but none of the forecasts gave me a huge amount of confidence that the sky would clear. I eventually decided to take a chance, packed up the car and headed out. For the first time in months, it wasn't totally dark when I arrived. After setting up, I noticed some thin cloud around but conditions were good enough for some observing. I started with the open cluster in M67. One benefit of arriving ahead of astronomical darkness was that I didn't feel rushed. I took my time and studied the cluster. I enjoy trying to find red giants among open

  33. Hey, I just got a brand new HEQ5 pro and a little guiding setup to go with my 72ed. Also finally got around to getting a light pollution filter! This is an upgrade from a star adventurer on a fairly cheap mount so for me it’s a massive step. As I have twins on the way in June it was also the last opportunity I had to spend some money on me ? As per usual it’s cloudy but supposedly Sunday will be clear. I’m going to practice with everything prior to that so that I know how some of it works.

  34. More images about comet C/2018 Y1 (Iwamoto): Comet C/2018 Y1 (Iwamoto) photographed on February 26th 2019. Since my previous image two weeks before when was at its maximum with magnitude 6, comet brightness has dropped until magnitude 7.5, decreasing at same time its coma angular size from 20 to 12 arcminutes. Tail also has faded quite, very faint and with only 10 arcminutes lenght toward East (to left). Telescope GSO 8" N f/3.8. Camera Atik 383L+. 167 min. total exposure. From Vallés, Valencia (Spain). http://cometografia.es/2018y1-iwamoto-20190226/

  39. The range to the hills from Stornoway shouldn't give rise to too many issues. The signal propagating from the reflection media will have been refracted and dispersed through the ionosphere and troposphere already. The may be some additional distortion, but the Scottish mountains are generally flat topped rounded hills (and quite wet most of the time too!). It's possible more bifurfication of the signal could occur however. The Icelandic VOR beacon is a very interesting proposition. The beacon at Akureyri is on 113.6MHz which is a nice frequency to use for meteor detection as it will

  41. Olly is absolutely right technically and as he says it is a lot simpler to use an apo. The question for me is do you want to be like all the rest? Same targets, same kit... There is nothing wrong with this it is a personal choice based on how you want to enjoy the hobby. If I wanted to go into imaging I would go for a scope that maximises the data I could collect in my very infrequently clear skies and poor seeing. Very different to Olly's situation. However, this is a complex issue trading off raw capability with failures due to technical problems and also taking account of

  43. For years with when viewing M13 with a 500mm Dob I would spend much time trying to see nearby IC 4617 (mag 15 and tiny) - never did succeed. So I could not resist pointing the C9/Ultrastar mono set up at the area. Just managed to get in the fov NGC 6207 (mag 11) and IC 4617 is just over third of the way from M13 to NGC 6207. On ce I just thought I got a hint of it using AV. Mike

I had to force enough Startools to make them look good. I am very satisfied because I had never gotten so deep. The EEVA is an inexhaustible source of new experiences and this forum a great place to share them This is NGC 4380 in Virgo

Great to see that even if I upgrade to an astro camera, I'll still be able to use the lens with excellent results! All pics were taken with the iOptron SkyGuider Pro (except Orion, I only had a tripod) and a Fujifilm X-T1 camera.
