  1. I did run some higher ISO shots but I just ended with overexposed sky. I guess I do need to find myself a darker location or a light-pollution filter.
  2. My first try at astro-imaging, just thought i'd post it for some cheers and/or constructive feedback. Canon EOS 1100D, 50mm f1.8 prime lens. 8s non-tracking @ iso 100 from a light polluted city balcony. Contrast enhanced in lightroom. My balcony is southbound (no view of polaris ever) so i've yet to figure out how to do tracking or setting up a GEM without being able to polar align. Thank you for watching
  3. The Samyang 800mm+DSLR+Nano tracker is a really interesting portable set up i had not heard about previously, thank you so much for the tip! The Samyang 800mm seems to be getting mixed reviews, then again it's very cheap compared to other things i'm considering, so it might be a logical next step. I just wished there was one with a motorized focuser that didn't cost the equivalent of a downpayment on a house. What's your experience with the Samyang for AP? The nano tracker looks very interesting and perhaps a lot less of a hassle compared to the AstroTrack or the Polarie. The weather in Sweden in February is treacherous. If you're unlucky the week will be completely overcast and rain mixed with snow. If you're lucky open skies and lots of degrees freezing - bring thermal underwear (2 layers is not overdoing it), cap, warm socks+shoes and extra batteries for your camera and tracker if you expect to spend any extended time outdoors I find gloves with a few fingers cut off are almost madatory if you're operating cameras or equipment outdoors in the winter here. Again, thank you for once again for making me confused as to what kit to buy
  4. @Baggywrinkle - I can achieve 20-30s exposures with my current merlin mount without having to polar align (i do two or three star align with Pointing Error Correction as i keep observing) which is why i'm not yet sold on the EQ mount as my next investment. Thank you for the tips on the app though - i will keep that in mind. I will also consider the Skywatcher and Borg refractor product lines. @rowan - Yes, i use the live view feature of my Eos1100d in combination with Backyard EOS software - it can even do some real time stacking of the live view frames. I think your last comment summarizes the problem well "milky way or planets" - i'm trying to do two things (at least) at the same time. I'm trying to get a feel for "how bad would the mak be for DSO" vs "how bad would the refractor be at everything else than widefield" and "which will give me my next wow moment"? It seems it is leaning towards the refractor both for viewing pleasure and fast optics - i also suspect there might be more long term exitement to find in wide field DSO viewing and imaging (there are only 3 viewable planets after all) - although i would feel bad if it would disqualify me from planetary viewing altogether. Is there some webpage or image that can give me a feel for what i can expect at 160x mag planetwise?
  5. Thanks for the reading tip. I will definetly get the book before i spend on anything else. I have done some research into EQ-mounts (the advanced VX seems best for my needs), and the importance of the mount for quality AP, and i know i might probably want one at one point - Just now however the fuss with polar alignment, and the big hit to portability is not worth it for me. My main observing site is my balcony facing due south, with has no clear view of the northern sky (no stella polaris!), and i will be forced to do meridian flips continoously. I would love to get both OTA's and i might at some point, but which would you buy first? Could you clarify what you mean by small image?
  6. I'm sure this question has been done to death, but my head is reeling from information overload after three weeks of research and i need to vent Some background 2 years ago my girlfriend got me a photographic tripod for my birthday. I used this with my Eos1100D DSLR to shoot the dark night sky at my summer house, and was simply blown away by the pictures that came out. Star streaks aside, the milky way was entrancing. I spent almost a week learning all about the constellations, and did some "manual plate solving" to figure out what i had shot. When i realized that one of those blobs was actually the andromeda galaxy, my mind was blown. For my birthday last year i wanted something bigger, so i wished for and got a small Celestron C70-mak cass spottning scope advertised as 25-70x. I promptly plopped it on the balcony for some nighttime terrestrial viewing, and was sorely dissapointed with the views at anything more than 30x. Blurry and out of focus when light levels were poor. I tried using the C70 on my tripod ball head but the small FoV meant finding and keeping planets or objects in view was a pain. I splurged some money on a small motorized azalt mount (synscan merlin) to screw onto my tripod for tracking of objects, as it would carry either my DSLR with my 270mm Tamron lens and 2x extender, or my C70. I also bought some USB cabling which meant i could control both the mount and the DSLR from my computer and have the equipment outside, which means i don't have to freeze while gazing (Sweden is cold). Being able to shoot jupiters moons was my next big wow. Being sorely dissapointed with the C70, i really want to upgrade my scope, and have been researching different scopes for the last three weeks, but i feel i have reached a dead end as i keep flipping back and forth between alternatives. What i want Optical tube assembly only as i want to use what i already have (quality photographic tripod, and merlin mount)To do both visual and "astrophotography" - I know that you will probably call me on this as this seems to be the #1 beginner mistake - but i really feel that shooting and saving some of the experience is a big chunk of the fun for me. I know the Azalt mount will give me field rotation, at this stage i think i can live with stacking semi short exposures as i do it for my own enjoyment and not beating those people with 24" dobs I want to have the ability to have the scope set up outside and sit at my computer and enjoy the view - but of course the ability to use it for visual as well.Portable - means should be carried by my merlin-mount on my photographic tripod - not more than ~4 kgs total OTA weight including camera body.Want to be able to do both DSO and planetary work (with a slight inclination towards DSO) - i'm a newbie here really looking for my next "wow" moment.Wide field of view seems nice, the C70 has taught me the annoyance of a small FoV.Stowable - not to big OTA as i pack everything up when i use it to not annoy my significant other half.My normal sky is in a pretty light polluted city, but i can get nice dark skies at my summer house.Pricewise i am not super sensitive, but also don't want to spend alot on something which will go into a drawer. I am willing to go to approximately the $1000 range at this point.What i am currently choosing between. - A refractor in the 3.x" inch range, currently the WO Megrez 88 seems enticing. - A 5" mak cass, the Skywatcher Skymax 127 is what i'm currently considering. A refractor seems enticing because of the FoV, the Mak-cass seems enticing because of the increased aperture (but will i be able to live with not fitting the pleiades into my view?) TL;DR: 5" Mak-cass or 3" refractor? Please, help me not regret my choice!
