  1. One of my favourite targets. It is beautiful just as it is, with it's overall composition, but even more interesting when you take a look at the different types of stars in the clusters. We can see white/blue as well as orange/red ones. 25 lights x 90 sec each 20 darks 20 flats 30 bias frames just 'cos they're easy to grab TS Optics 115mm triplet apo Celestron AVX Nikon D5300 And yes, the picture..
  2. Yes, dew heater solutions will be amongst my future purchases
  3. Hello, Was out testing a Nikkor 35mm on a Nikon D5300 mounted to an AVX mount. Aimed at dense region and fired off 29 shots before everything frosted over completely, along with 20 darks. Stacked in DSS and postprocessed on Photoshop. Had the lens wide open at F1.8 and exposed 30 secs/image unguided ofc. I kind of like it. Good lens also.
  4. Agree with you regarding this winter. We've had about 4 clear nights since the end of November in Sweden. I'm not even angry anymore, I just laugh at it. Thanks for sharing the pic. Good one.
  5. TS optics 115mm triplet apo Nikon D5300 in prime focus Single shot 1/125 @ ISO 125 Decreased lightness a bit in Photoshop Sharpened slightly so not entirely as shot but almost.
  6. To be honest, I think this is a very good image
  7. Throws in a link aswell: Was recommended by an observer, regarding solar filters, that glass filters of high quality was the best. I should say though that I have no experience with the Baader solarfilm that was mentioned earlier, so might be a good option as well. I've heard that this line of Astrozap glass filters is good. You have to know the outer diameter of the tube though so not only the aperture. https://www.teleskop-express.de/shop/index.php/cat/c61_Solar-Filters-for-white-light.html Also, if you're in the UK you might want to consider a UK retailer such as FLO because of the shipping cost. Not sure what Teleskop Express would charge for shipping to the UK? But atleast it should give you an idea what to look for.
  8. Rest assured, I would never buy a solarfilter that screws on the eyepiece. I didn't think that such were sold to be honest. No, what I intend is of course the kind that is fastened over the objective. Would not want anything to shatter inside the scope because of intense heat buildup (diagonal, eyepiece) now would I!
  9. The one accessory I could think of, that really would add another dimension in the use of the scope, would be a solar filter. I myself is planning to get one. When observing DSO and planets, one pretty much knows what to expect. The sun is dynamic and a living object that can be different from one time to another. Also it might double the chances to use the scope. It can be a clear day but a cloudy night. So that is my suggestion. The BST Starguider eyepieces as earlier mentioned, are also highly recommended. Very good quality for a good price. Best regards.
  10. Wow that diagonal would really match my 115mm triplet very well. Too bad I already have a high quality 2" 99% diagonal. But it sure would look splashing, and in very good condition too. But can't really justify the purchase. I wish you good look with the sale and I am sure someone else will be happy with the product. Sorry for this (for you nonproductive) post but please consider it as free advertising
  11. Agree about the glare. Tried to photograph it with phone through eyepiece and this is what I got. 100x mag if I remember correctly. Will try with a moonfilter next time observing. I think the the side facing us was almost fully sunlit that time.
  12. Good luck Also, I forgot to mention: Before I start with adjusting the lat/az knobs, I sight in on Polaris over the mount saddle. Kind of like sighting with iron sights on an old rifle. Hope this makes sense? Then I put the scope on and balance in RA/DEC etc. And then I proceed with the process described earlier. I use a 38mm (21x) eyepiece in the beginning when star aligning. And carefully align so that I have align star i center and same with calibration stars. It is not 100% polar aligned but fairly close. The whole process takes some 5-10 mins if you have the routine. And when I slew to objects when done, they're almost in the center up to 100x mag eyepiece. Also good enough for 30 sec exposure time imaging. So all I'm saying is: Don't fork out £300 on a polemaster just yet as I think you don't need it. You would also need to hook up computer with sharpcap etc making it not so spontaneous anymore. Instead get the location and time settings both on handcontrol and alt/az knobs as exact as possible. Check your lat/long coordinates f.ex in google maps. 10 mins and you're up and running. Always try to find ways to make it simple And, most important, have fun and enjoy
  13. Short answer: Eeeh, what? I don't. Sometimes If I know just about what I will be looking at, I adjust the height if the tripod so that the focuser/eyepiece part will come in an okay position. Adjusting the tripod so that the scope when paralell to the ground sits in a chest level position is usually good enough. Yet when doing this, I end up chosing targets that makes me kneel at the eyepiece and thats just how it is sometimes. Usually I can rotate the focuser part to make sure that the eyepiece comes in an okay position anyway. I don't use an observing chair. The more equipment I have to haul out, the more it ruins the grab and go feeling.
  14. I have an AVX mount. ANd living on lat 56 degr north means the polarscope is useless unless I don't want to poke my eye out because of the long handle on the bolt (and how the bleep can they sell a mount like this??) So I do this which is good enough for visual. I find out my lat and long position. This for entering locaton in handset. I set my lat adjustment on the mount as exact as possible. Then I adjust with the azimuth knobs until I have polaris fairly close on the finder. Then I do a two star alignment and add one or two calibration stars. This is good enough for visual. If you just do visual, don't over complicate things with a polemaster. Just adjust with the knobs as close as possible and also enter your position with lat/long coordinates and exact time. This makes my mount slew to chosen targets and put them almost always fairly in the middle of the eyepiece. I believe there should be a polar aligh routine in your mount, not sure about the menu location though. The avx has one that is said to be quite good. The option might be visible only after a star alignment routine has been done. Check the manual.
  15. I suppose a regrease is good, if the mount has a few years on its neck. When old, some grease tend to get chunky/hard. Other than that, it is a good and capable mount, so I would see how it performs first, before taking any decisions. I'm that "use what you have and see how it does kind of guy" It might just do very fine. I am also planning to get into the AP-hole. With an 115/800 triplet and an AVX mount, I'm sure I am in for a real blast. Avx is maybe not the best imaging mount, but found it used for good price, so planning to follow my own advice and see how it works first. I'm sure your mount will perform excellent with a little new lube and a small frac on it.
