  1. Wonderful image! May I ask: The camera, is it fullframe or DX format? Asking this because I might want to try the same region with a DX 35mm F.18 I have to my Nikon D5300 (aps-c), and trying to figure out what the fov would be.
  2. Hi, Generally zoomlenses doesn't really have that "oumpf" when it comes to clarity and sharpness, however this zoomlens has gotten consistently good reviews. Also I think that the higher FR contributed further to the sharpness . It is just a slight tad softer fully wide open at F3.5, so it was lucky I forgot to open the aperture fully. I've tried the 35mm F1.8 fixed lens also and even though it is a fantastic lens in all aspects, Miky Way is imho not the right target for that lens. In general I like it when MW shots are very dense and 35mm tend to open it up way too much for my liking. 18mm being on the border of too high IMHO, I'd like to try some of the rokinon / tokina 14mm and 12mm, I am sure that would be a real blast And yes, the camera seems to be quite sensitive to Ha even unmodified. And that's good because I like to use it as a daytime camera too
  3. And here is the final image including flats. Made the image a little cooler overall also.
  4. Hi guys! As the weather has been clear. I have taken the opportunity to do some shooting Wanted to shoot another object, but since my AVX mount didn't behave well at 300mm FL (usually tracks well but could hear some strange glitches from the drivetrain tonight), I decided to go widefield instead. I just love shooting the Milkyway and since I had to change plans and rethink, I decided, just for the fun of it, to try with 240 seconds at 1600 iso, just to see what I would be able to pull out. And the result is very promising. Will shoot some flats tomorrow to complete the set, but I couldn't help to try a stack tonight and some postprocessing in PS. And let me tell you guys, it didn't require much postprocessing at all, just some enhancements here and there and also did some evening out on lightpollution. Even on the TIF that Deepskystacker spat out, I could see clearly the nebulosity areas. Will do another complete stack tomorrow after shooting a bunch of stacks, but just wanted to share this spectacular image. Image data: Nikon D5300 unmodified Nikkor 18-300 @ 18mm F5.6 (forgot to change to lower fr) ISO 1600 22 lights @ 240 seconds each 15 darks 15 bias And the image..
  5. Hi folks! For various reasons I managed to get only slightly over an hour imaging time. Pretty pleased with the result nontheless. Equipment: Nikon D5300 Celestron AVX mount Nikkor 18-300 @ 135mm F6 Exposuretime 240 secs / image 20 lights out of which 15 got stacked 20 darks 20 bias 30 flats Aaaaaaand... the image
  6. Very nice especially for a first attempt! Looks crisp and natural!
  7. What can I say. Not only is it a beautiful capture of the Milky Way, but you also nailed the composition as such. Thanks for sharing
  8. Thank you I just felt I maybe processed it too hard and since it's always fun to go back and reprocess the data with new learned insights and ideas, I might do just that some day. But overall happy Thank you! Always nice to get an opinion from another set of eyes. May I ask which version you prefer the most?
  9. Yeah do so Maybe you cannot go 240 or above seconds with 50mm but you don't know until you try, you can just try with an exposure for say 240 or 320 seconds and then analyze that frame and see how the stars look, if they look okay just fire away I generally tend to not think "I cannot do this" but rather "What if I can?" which tend to open up much more possibilities So give it a go and see what the result is. We're going to have clear weather in Sweden Sunday night so if the prognosis is true, I will probably go out and do another sequence
  10. I don't see why you couldn't That mount is the predecessor of the AVX iirc? Should have similar capabilities, and also that low fl is very forgiving I even forgot to do a proper polaralign for this shot, just sighted in Polaris over the mount saddle.
  11. Both images are absolutely fantastic. Composition, background, just everything is brilliant. Beautiful!
  12. Forgot to take flats, but shot some 20 darks and 20 bias. 10 x 240 seconds unguided Nikon D5300 Celestron AVX mount 18-300mm lens @ 18mm F 3.5 ISO 400 Can see some vignetting due to no flats but overall nice picture. 1st one more or less straight out off DSS, other one postprocessed in PS. In retrospect I should not have shrinked the stars so much, because I like how "explosive" the image feels when the stars are so visible. Might try another postprocess somewhere in between these two. Taken 2 weeks ago. Pretty dark. Have a nice day
  13. 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..
  14. Yes, dew heater solutions will be amongst my future purchases
  15. 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.
  16. 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.
  17. 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.
  18. To be honest, I think this is a very good image
  19. 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.
  20. 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!
  21. 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.
  22. 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
  23. 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.
  24. 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
