  2. Between work/family/really poor cloud cover when I might have gotten out, the sad fact is that this was my 1st night out this year with my 15"! It has been eating me to see the darkness eroding away and we have the daylight saving time change coming up next weekend... so I was like a kid getting out last night - it was a beautifully clear blue sky all evening. With my recently washed mirrors, I threw the scope in the car and headed for a little spot on the coast 10mins from my house. Hmmm... "ceilings" of fog were appearing in my headlights as I drove down - I feared this but kept g

  3. Here is my completed image of NGC 2403, captured in LRGBHa. It's taken some time to get all the data together and process. In fact, I think this is the first image I've managed to produce at all this year due to some circumstances. Strangely, you don't seem to see NGC 2403 as frequently as it deserves - it's actually quite a decent size in the sky and is visible all year round from the UK, albeit a little low in the summer. It's part of the M81/M82 group and, being face on, it does look somewhat like M33's little sister! The Ha really adds a lot to the galaxy, there's lots of interes

  4. Welcome to the new electronically enhanced visual astronomy or, EEVA section on SGL Over the past few years, a number of new avenues of amateur astronomy have developed: video astronomy, live stacking, night vision and others. There has been lots of debate and discussion on what to call these, where they belong and how they are defined. Unfortunately this has often led to conflict, disagreements and entrenchment. SGL wants to encourage these new forms of astronomy, we believe they are going to be hugely important areas and want to help foster and grow the techniques, methods and equ

  6. Hi all. Martin aka Grumpy Martian recently started a thread to help him decide between buying a 6" f/5 Newtonian and a 4" f/7 Refractor. I've often thought either of these could be all the scope you ever need. Both scopes can be used effectively for many areas of astronomy including; DSO imaging and observing, planetary imaging and observing, solar, and EAA. so I decided to put together a video singing their merits....not literally singing their merits, you don't want to hear that I really do think either of these could be all the scope you ever need, but what do you guys thi

  9. My 12" Dob has been outside for several days. I made the decision to view DSOs in Leo last night but before starting I wanted another go at the Medusa Nebula. My various observing guides recommend a wide FOV EP + an O-III filter. So I used my 30mm Revelation + 2" Castell O-III. Using my 80mm finderscope it was easy to find the location using the Interstellarum atlas. Did I see it? Well I could make out a very faint 'glow' not totally certain but it was in the right place. Over to Leo and these are the Galaxies that I observed over several hours - NGC 3193, 3190, 3226, 3227, M95, M96, M105

  10. A very generous gentleman on the forum (I’m sure you can guess who) has leant me his Photonis NV monocular to try for a little while. Fortunately I have had a couple of clear nights this week and the opportunity to give it a spin, so, here is my report on what happened and my thoughts so far. The Kit I have borrowed consists of the Photonis NV monocular, a 55mm Plossl, a 32mm Plossl, an adaptor to connect the monocular to the eyepieces and one to connect 2” filters to the monocular for x1 viewing. Finally, there are two Astronomik filters, an Ha 6nm for viewing nebulae and a 642nm ProPlan

  11. I welcome this development and hope that it will see NV and other electronically-assisted observers getting together to discuss DSO observations. And I also hope that traditional visual observers will feel welcome to chime in with their observations too! Perhaps we can set up some monthly challenge objects and compare notes. Just for clarification: I'm assuming that the Discussion sub-forum (this one) will be the place for discussion of equipment, software, observing techniques etc, and the Reports sub-forum will be limited to observational reports (as opposed to reports on say a new bit

  12. To put this in perspective, I bought my first SCT nearly ten years ago. And in all that time, there has been one word that has scared me witless (no, that's not a spelling mistake ) ... collimation!!!! There are so many horror strories around of people scratching corrector plates and simply messing it up completely and making a scope unusable, that I have always avoided it like the plague ... once even preferring to sell the scope I had and buy another one to avoid having to do it [don't you just love the logic of that one?particularly when there is no guarantee they will arrive collimate

  15. Observing Report 25/3/19 A clear sky and a free evening coincide at last! First up was setting up the 200p for an imaging run on M101 (still stacking!) and then a nice little session with my son and the 8 inch Dob. Betelgeuse was first up and discussing how if it was where the Sun was we’d be in it! The Orion Nebula at 48x was a nice site, with the 4 brighter trapezium stars quite distinct. We then moved onto the Double Cluster which filled the eyepiece at the same magnification- so many stars! Finally we had a look at M65 and M66 in the Leo Triplet. A bit of family t

  16. Hi everyone I didn't realise this was possible with basic stuff and now wish I'd started with a longer FL. Several galaxies emerged surprisingly bright. Just hoping for the urge to start over again with something bigger... Oh and not a good background. Linked with my poor processing, maybe a limitation of dslrs over long exposures? Thanks for looking; gotta love that 's' shaped galaxy:) 700d on pn208 20x8min @ ISO800

  17. Just an update, below is the final list I discussed with Steve at FLO: Steve is kindly letting me keep each scope for a period of two months, plenty of time to get some quality time under the stars, and to formulate a balanced review. First up is the Skymax 102 AZ Pronto outfit, ETA around Monday @ Steve and Team FLO ?

  19. QHY183M arrived earlier In the box: Pretty much bare bones but no interesting extras! Standard 12V cable (bottom right) is redundant. USB 3 cable (middle) is a bit short but will probably do for now. ST4 cable (top) is redundant. Desiccant and tube (top right) pretty much redundant - if you don't undo the screw for the desiccant tube, you probably won't need to! T2 to 1.25" adapter (top) might possibly get used but not necessary at the moment. The 12V power mtof lead (top left) with screw connector could get used but probably isn't necessary.

  20. I decided last night to try my S.A. with an old 400mm Tokina 400mm f5.6 lens on a Nikon D5100 mono modified body. Although I have the Pro version of the mount I decided to just mount the camera/lens on a ball head rather than the the dec shaft and counter weight. I pointed the lens at M51, focused by zooming the image on the camera's live-view screen. I set the iso at 1600, shutter to bulb, connected a shutter release cable to the 'snap' socket on the mount which gave me circa 100s sub frames. There is a firmware update which allows other variations but I'm using as supplied at present.

  23. Found that thread and read most of it. Seems there is a purist attitude from some visual observers towards NV. But when you guys express the same purist attitude towards the rest of the eaa observators, you just make the visual purist's point even more valid. On the other hand I' ve read some posts on planetary AP, from people like Avani, that are pure observational reports based on the images he gets, and that to my eyes is great observation report.

  24. The older I get, the simpler I like things to be, and as a visual only observer I don't care to fuss about with unnecessary gadgets. So, considering that my Wife and I like travelling to dark destinations, our little kit here would be my one scope choice. .

  26. English not being my native language, perhaps has me confused. I can't understand what the problem is? Do NV users feel they can't post their observations in the general deep sky observation sub-forum? I don't think there is any rule against it, if they feel like doing so. Or do NV users feel there should have been an even more specific subforum devoted completely to NV? Come on now, a refractor owner is not supposed to join in discussions about newtonians, if he has no interest in them, despite all of these are in the "scopes- whole setups" subforum.

  27. Latest iteration. Just sold a pair of 15mm TV Plossls and bought a pair of 15mm Panoptics. Added Lumicon UHC and Deep Sky 1.25" filters too as they came up at a decent used price. Just need to do a bit of observing now!

  28. There is really simple way to deal with any LP if imaging. Just throw more total exposure at the target and at some point you will reach satisfying results. It might take a while, but you will get there. Maybe not this season, but next one ... or one after that

  30. Very interesting to read about your experiences chasing PG 1634+706. Having similarly spotted 3C 273 with my own 10” f/4.7 dob recently I became inspired by you and Stephan. 3C 273 blew me away with the mind boggling characteristics and also the confirmation of my ability to detect faint objects. I have only observed with a telescope since September 2018 and I’m obviously still learning a lot about the capacity of it. I thought mag 13 was about the limit for stellar detection under my circumstances but reading your account got me thinking that it might be possible to go a lot deeper.

  34. Thanks to this thread and the reports / charts posted I've been able to spot PG 1634+706 with my 12 dob tonight. Thanks very much folks It's very, very faint indeed. I've found around 400x magnification and a combination of slightly averted vision and the "1000 yard stare" has helped this dim point of light show against the background sky. 8.6 billion light years - wow !!! Those photons have been travelling for nearly 2/3rds of the age of the universe .....

  36. This was my point earlier Grant. Even as part of a wider EAA section, there are nothing like enough night vision users to support interesting threads/discussions. It will just become a backwater. I sympathise with you to the extent that no solution is going satisfy everyone. But if night vision had always been confined to a little visited corner of SGL, I might never have got into it. It was Gavin posting in the general equipment and observing forums that spiked my interest in the first place.

  40. To me there is no significant difference in calling it EAA, Videoastronomy, NV astronomy or EEVA. The significant part is the addition of the observation sub forum. It will encourage us to post more observation experiences, which were here before but more in context with the "behaviour" of specific equipment as means of comparison. I don't think anyone should feel left out, because they're not. Now get out there and get some observations coming in!?

  41. Obseravtory in action.mp4 Snapped this one last night just before the moon came up 3x600s of Luminance added to some RGB I had from a while back. Its an extreme crop from the full frame just wanted to keep it nice and tight. My AG12 Newtonian and H35 Starlight Xpress. I have also just finished my observatory cam so I can keep an eye on the scope while imaging from the house. This is a little time lapse thrown together with the results from the session shown at the end.

  43. I'm sorry you feel this is an attempt to hide away these new techniques particularly as the aim is the absolute, complete opposite. We genuinely believe these sorts of techniques are a big part of the future of amateur visual astronomy so much so, they deserve their own section and, this is just the start of some of the things we hope to do on SGL to encourage these newer areas of astronomy. I hope that after reflection you reconsider.

  44. An excellent, easy to listen to video Chris. I really can't fault your reasoning in any way and completely agree that if I had either of the scopes you mention, I be a very happy observer. Both scopes are very capable and serious instruments that could provide a lifetime of enjoyment. Of course, I'm of an age where I can remember if someone owned a 4" refractor or a 6" Newtonian, they would be regarded with a measure of awe, and with good reason. After nearly 40 years at the eyepiece I'm still passionate about 4" refractors and rarely imagine using anything else. With regard to Newtonians, I c

My first proper Narrowband image, captured at silly o'clock this morning, 120s x 20 in each Ha, Sii and Oiii, then I added in 9s x 50 in LRGB, Same amount of darks as the filters and exposures, and flats added as well. Not guided via camera only on my mount as my guiding needs tweaking! Any advice / guidance will be highly appreciated Taken with a Esprit 80, with field flattener, and a zwo 1600mm-Pro cooled down to -20. I used APT for capture and stacked and attempted process with AstroArt .
