Guest Si2504 Posted February 12, 2016 Share Posted February 12, 2016 As some of you know, i'm reasonably new to the telescope scene. Although i've previously owned a newtonian reflector, i recently purchased a Skywatcher 80ed PRO amongst other things, mount etc. Unfortunately, due to the weather of late, i hadn't really had the chance to try it out, until yesterday (10/2/16) My first proper outing with it mainly consisted of learning the scope and mount, and doing more observing than anything else. However i did get a bit of imaging in, M42, a good starter point i thought having previously took multiple images of it with just DSLR and tripod. so this was more of a learning curve for me more than anything else. I didn't bother using the guide cam as i didn't wan't to complicate or put too much pressure on myself right away. so here is my result, 19 minutes total exposure (stacked in DSS) ISO 1600, 5 dark frames and 5 bias frames, Canon 70d. hope you like it Link to comment Share on other sites More sharing options...

Guest Si2504 Posted February 12, 2016 Share Posted February 12, 2016 Thankyou everyone:) i was really gobsmacked when i viewed the very first raw picture when i was testing the exposure. Can anyone give me any tips on how i could improve things the next time out? Recommended number of images or target total exposure time etc.. The one thing that really mind boggles me is trying to thing how long an exposure should roughly be for a particular object to get the most data from it. I also had to be careful on the exposure time due to being surrounded by residential street lighting. Any tips and help is greatly appreciated. Thanks Link to comment Share on other sites More sharing options...
AstroHobbyman Posted February 12, 2016 Share Posted February 12, 2016 Super picture , just did my first shot of that last night, the tip I got from a club member was get as much data as possible so I guess that would mean for you work out Max exposure time before the street lights spoil things and take loads of lights and darks as many as the tracking and resonable time allows, maybe try ISO 800 to see how it effects noise. Above all enjoy! Link to comment Share on other sites More sharing options...
Guest Si2504 Posted February 13, 2016 Share Posted February 13, 2016 done a bit of reprocessing and managed to bring out a little more detail Link to comment Share on other sites More sharing options...

Guest Posted February 14, 2016 Share Posted February 14, 2016 Great image, I agree. Just curious, how long were the individual exposures? Only thing I can think of is shooting 8 to 10 darks instead of 5. Link to comment Share on other sites More sharing options...
Guest Si2504 Posted February 15, 2016 Share Posted February 15, 2016 Each exposure was 1 minute long unguided. Thanks i will also try more darks next time. Link to comment Share on other sites More sharing options...
