  1. 2.10am Friday, clear (for a change), very cold, 8SE cooled in Dobhouse, aligned on Capella. (Southern sky poor with light dome from intense "security" lights.) Note to self: Do not breathe on the eyepiece! Struve 718 - perfectly matched 7th mag stars, 7.7" separation. GoTo OK - only did one-star, so target was in the 1.28deg FOV. Easily spotted at x56 in a field of fainter stars. (Nearby 10th mag stars were very faint indeed.) Clear split, very close, lovely equal pair, secondary at 7 o'clock. Struve 736 - 7th and 8th mag pair, 2.6". Much trickier - tighter, mismatched. W

  2. Unfortunately stock availability has not improved. Most factories in China have reopened and are running at full capacity but there are not enough container slots available on cargo ships. The cost of those that are available have increased significantly. We hear container slots are being cancelled without good reason then resold at much higher prices! In these circumstances it is near impossible for importers to provide reliable ETAs unless a ship has been loaded and is already enroute. Even then its arrival is subject to delay because most shipping companies are avoiding Felixstowe, which is

  4. So most of us are supposed to stay within a few miles of home, some of us shielding can't leave the house.Claustrophobic yet ? Well last clear night I was taking photographs of something 205,751,888,000,000,000,000 miles away.So that's one way to think about the lockdown restrictions.

  5. This beautiful thing arrived from RVO by the nice dpd driver, I ordered it during clouds so hoping it'll have the reverse affect and bring on the clear nights now. Its a much more portable setup for me with my skymax 127 and can get everything down the 2 flights of stairs in one trip. It'll be so brilliant to finally get a scope outside as I haven't managed before with my previous set up, I'm looking forward to viewing the early phases of the moon and more westerly and northerly parts of the sky, once 'm outside. On the quick test of setting up in my lounge it certainly works well and a breeze

  6. My goal was to emphasize the foreground nature of this dark structure. Its easy to have this dust cloud appear as background sky with a little clipping of the black point, which is often mistakenly done when the data contains a lot of noise. FSQ 106 with .6x reducer and ASI 1600. This is a center crop of a wider FOV. 9 hours using SHO palette. about evenly distributed exposure times. I would like to shoot this again with more aperture and bigger sensor.

Tonight I landed on them first go and all 3 were visible in a single view. Can't believe I've only been doing this for 9 months now. Feels much longer!

  8. After over a week of heavily clouded nighttime skies, I've been surprised by a clear start to this evening ! In the interests of getting out there fast I've put the Tak FC100-DL out. The seeing is actually quite decent. Mars, though just a 9 arc second disk now, is showing the long northwards projecting snout of the Syrtis Major and the adjacent Mare Tyrrhenum extending to the south west. No sign of the south polar cap. The northern polar limb seems pale and hazy. The phase is 89% illuminated - noticeably gibbous. Uranus, grey / greenish disk quite crisp at 300x. Not in th

  9. So this is sort of first light with the 61EDPH. I say sort of because I had a short window of clear sky previously which I used just for testing - the upshot was that I got unacceptable chromatic aberration so put serious imaging on hold until I could sort it - and I think I have succeeded. First thing to say is that the field is lovely and flat - much better than anything I could achieve with the TS72/reducer combo which I bought previously and returned as unsatisfactory which fortunately 365 Astro were happy to exchange. There is an example image posted with the advertising spiel which

  10. I have a black diamond version of the Skymax 150 mm. I have owned a few Maksutovs in the past including an older champagne colour version of this scope. My understanding of the capabilities and attributes of different telescopes designs has finally come home to me after chopping and changing telescopes over the last few years. I have to admit that I have only recently appreciated that some telescopes can give bright views with very black skies (high contast). Well this Skymax 150 mm does deliver on this. Also there have been times when I have been observing I have seen stars as tight

Busineses as well as the general population have taken awful and tragic blows and the News media broadcasts the figures daily, and pretty demoralising they are. However, perhaps the beginning of the end is about to commence, (Part of a famous phrase Winston Churchill used in the House during WW2).

  13. Just delivered Wednesday. I generally binocular observe with 10x because I like going deeper than a 7x or 8x will allow, but sometimes recognizing starfields when searching for the quarry in my dim light polluted backyard sky can be troublesome with their narrower field. Some recent reviews on Kowa's 6.5x32 prompted me to try the 10° field they offer. Used them last night under clear, but windy conditions, my 10x50s alongside, and I am sufficiently impressed enough that the Kowas will be with me for any observing session. I think of the 6.5s as a "finder" for any higher mag pair I'm

  15. The lens looks perfect, as does the entire telescope. The FS is the right choice in this instance. The real life difference between any of the Tak refractors is quite small, so the price difference means your FS102 is a fantastic bargain. As regards the fluorite element, it is true that the FS uses a front fluorite element, but Takahashi use a super hard coating that protects the lens. The fluorite will be perfect in a hundred years from now if you take care of your scope. All the nonsense that can be read about fluorite being unstable is largely scare mongering from competitors. You have a

  16. Oh, I'll definitely be proudly uploading any images that I'm suitably pleased with. I'm attaching it to my baader zoom so I have high hopes! If I can get shots any better than these, which I got last Year by simply putting my phone up to the stock 25mm & 10mm eyepieces that came with my scope, I'll be a happy man with my initial modest investment….

  17. So out of the box came this Celestron CPC925, a thing of beauty! The boxes got delivered really quickly by FLO and all looked in great condition. Looking visually it all looks undamaged. First impressions of this scope are that it has excellent build quality, I hope the optics match. The tripod is fantastic, I think you could balance a circus elephant on it! I think the tripod is standard for the whole range so I guess it is a bit large for this mid range scope. My Mrs face was a picture as she came into the room. “Gee willikers, what is the killer robot from Robocop doing in

George is a physics Senior Lab Instructor at the University of Northern British Columbia in Canada, where he often gives public outreach talks and demonstrations. A childhood interest in space and astronomy led to his career in physics. Gravitational waves, first observed in 2015, are produced when compact objects such as black holes and neutron stars merge. Just as useful astronomical information can be extracted from light wave signals

  23. You make some interesting points Martin.. In my time I've bought and sold, at a guess, probably 50-75 telescopes., often owning 6-8 scopes at a time! Many of these were older refractors which I bought as I loved long, older achromats (I still do in many ways). But I've also owned a fair few Maks and the odd SCT or reflector too. But if I'm honest, one very good long achromat of 80mm -100mm performs very much the same as another of the same aperture and optical quality..they might look a little different or have a crayford focuser instead of a rack & pinion, or vice versa,

  27. I love your reports Doug. Doubles are really wonderful things to study but can be problematic for someone with Obsessive Compulsive disorder. When i read your adventures i think to myself "I should really invest in a microguide eyepiece"! Stars in general are fascinating and just about as beautiful as any astronomical object gets. It seems ironic that most observers pay little or no attention to them. I'm guilty of being intermittent in this regard myself! Thanks for posting!!

I had unusually goof seeing for me for this shoot as I recall. 17 hours of data (9 hours RGB and 8 hours Lum). TOA 130 and ASI 1600. I regret not capturing Ha. This is a fairly aggressive Crop

  32. This is a question that comes up often, and views are split. Personally, I'm a fan of zooms for medium to high power use. I have a range of fixed focal length eyepieces, but use zooms much more often. I agree that fixed focal length eyepieces may be slightly better corrected when compared with a zoom at the same magnification. But that's not always a fair comparison as that magnification may not be the optimum for a given object. This is because one of the many advantages of a zoom is to be able to dial in precisely the best focal length. For instance, this may be 13mm or eve

  33. After wondering where my delivery was I checked the Hermes tracking portal to find that this was delivered yesterday and left in the rain at the side of my house. No knock on the door, no notification Despite the wet cardboard sloughing off, my new flight case remained undamaged. I've been trying for a while to find a case to hold my complete imaging train (guide scope-'n'-all), but everything I found was either too short in 1 direction or excessively large and expensive. This from Maplin was reasonable at £50. From memory, the internal dimensions are about 30 x 30 x 70

  34. This came today. An old model and used (it's in great condition) , but it cost less than I paid for a chinese takeaway for me, my wife and son on Saturday night! Just waiting for the connectors to arrive, so I can attach it to my scope. A cheap intro to astrophotography, that now worries me that if I get some even half-decent results, will soon become an expensive addition to this hobby!

  38. On 20th Dec we finally had a bit of clear skies. Because it was pretty windy I set up the SW 130dps & set about taking subs of M33. It wasn't the target I had in mind, so during set-up I had the DLSR (Canon 600d astromodified) rotated almost 90 deg to my normal orientation... (and so the Galaxy wasn't framed well). On initial stack of the data, I noticed each of the light frames had a line which looks like some light leakage or reflection, which I haven't seen before. Any ideas what this might be? I had a black shower cap on the primary mirror end of the scope (which blew off half way

  39. Althoguh I can clearly see there's something wrong with the stars(I have enlisted the help of the big brains in the help section) I wanted to share this, since it's still only my third astrophoto to date. Since I noticed the halo effect on the stars, I only did a quick and dirty edit, but star halos aside, it didn't turn out too bad. But about the halos. I focused with a bahtinov mask, rechecked focus twice throught the night and stars seems to be nice and round(and in focus as shown below) across all the individual subs. So my first thoyught was a stacking issue. I've tried stacking o

  44. Hi Doug. I too never used to observe double stars. However since I got my 10" dob three months ago every in the night sky is fair game, and I've found myself becoming addicted to observing double stars. They are indeed breathtaking in their beauty, colours and configurations. Glad you got some clear skies Regards Joe

I'm starting to get astro-withdrawal symptoms Still, it's nice to be reminded that there are still some stars up there if the pesky grey blanket shifts one day !

  46. 13 January 2021 2314 hours Messier 41 Following the star maps from Sky & Telescope, I found M41 below Sirius. ES-102 mm refractor. Started with 14mm and 2X Barlow and then used 32mm X2 and 25 mmX2 and then 12x50 binoculars. Could not find it naked eye. (Bortle 6-7 sky.) Identified: Orange-yellow star in the middle of the visual field. About 25 stars easy to see and maybe another 25 fainter also in the field. FOV = 50/77.5 = 0.66 degrees = 38.6 minutes. 14 Jan 1100 hrs. I put all the equipment away and checked the write-ups online about M-41 and found that my observations align

  48. I'm sure someone will come up with the proper technical description, but basically, the parts of your retina that are very sensitive to low light, do not detect colour. In order to be able to see colour in an object, it must be bright enough. Children / young adults can detect colour in DSOs that we oldies can't see, either!
