Hi Guys! My name is Daniel and I am from Ecuador, I love astronomy and the secrets our universe holds. I love Jupiter, our big brother, so I opened this forum to talk about facts, secrets, theories, etc. About our gas giant!

Hi... Hope this is ok to post here. I've built an app to create star trail images and videos using an iPad or an iPhone and i'm really struggling to find beta testers. Check out the photo and video I've added to the post to see what it can do and and click the link if you want to try it out. https://sites.google.com/view/starstackerforios-beta/home for info. https://testflight.apple.com/join/7iLGfVDG to get the beta. It's free to have early access to the beta. I'm just hoping to get a bit of feedback before it releases. Many thanks! Star Stacker iOS.mp4 -

Hi all I have been imaging M45 and have come up with this form of issue with the stars. It almost looks like I have left (and I did think this) the Bahtinov mask on, however I didn't. This is not the first time I have noticed this star issue. Any ideas? This is my equipment: Explore Scientific 80ED Apo Triplet; Explore Scientific Field Flattener; Canon 250D mod; 2in UHC filter; 60mm Guidescope; ZWO ASI120MC-S.

I took these two photos only seconds apart. The top bit I took secondly. I’m not sure what it is I’ve captured. But can anyone tell me what it could be??

I am selling my Star Adventurer Pro bundle. The full set is packed in a flight case ready to go. It also includes an extra counterweight pack (an extra 1kg weight and extension bar). I use the additional weight for balancing an ED80 or my Lunt Ha scope. It has seen very limited use so is in excellent condition. I am asking £169 (no offers) pick up from the Harrogate area. The bundle weighs close to 8kg. Bank transfer please. In the flight case: Instruction manual SA mount Ball head adapter Illuminated polar scope Dovetail L bracket Equatorial wedge -

Taken in Scarborough, North Yorkshire on 16 December 2017. My main aim with this image was to show those just starting out in the world of astrophotography what can be achieved on a budget with simple and affordable equipment. Using my iPhone and the NightCap app set to Star Trails mode I captured this as one image over a period of four hours (hence the number of airplane trails!). I then edited the image on my iPhone using the Snapseed app to darken the sky and bring out some colour in the star trails. I was very pleased with the outcome given that all of this was achieved using-

edit: Processed in January from data captured in June and it has been pointed out to me that, as per the rules, this image can not be considered for the competition. .............. The Fighting Dragons of Ara ( NGC 6188 ) ( please click / tap on image to see larger ) Image details: This is an HDR image constructed from exposures ranging from 2 seconds to 240 seconds in length. The aim was to capture the faint stars and details in the nebula whilst at the same time maintaining colour in the bright stars without clipping the highlights. Plate Solution: Res

The Fighting Dragons of Ara ( NGC 6188 ) ( please click / tap on image to see larger ) The Fighting Dragons of Ara ( NGC 6188 ) Bright Nebula NGC 6188 and open cluster NGC 6193 are embedded 4,300 light years away in the Sagittarius arm of our Milky Way galaxy and can be seen with the naked eye south of Scorpius in the constellation of Ara. With powerful stellar winds and energetic ultra-violet radiation, massive stars sculpt the interstellar gas and dust of the nebula into wonderful shapes and cause the interstellar gas to brightly fluoresce. Closer to the hot

Eta Carinae Nebula ( NGC 3373 )with the bright unstable star Eta Carinae in the centre of the image. This is still a WIP - I am capturing more data tonight and the processing needs tweaking ... Edit: A quick and dirty adjustment on my ipad ( the original is too green I think ) ............. Original: From Wikipedia ... "Eta Carinae is a highly luminous hypergiant star. Estimates of its mass range from 100 to 150 times the mass of the Sun, and its luminosity is about four million times that of the Sun." This HDR image

Imaging variable star in bad weather
Guest posted a topic in Observing and Imaging Double and Variable Stars
Hi, I am doing an end of degree project on variable stars due next thursday and London's weather does not allow finish it. I was wondering if someone would do me the favour of observing the pulsating variable star V0460 Andromeda http://variablestars.net/stars/460/ in the Johnson R filter, for a period of 1 hour and 50 minutes? please? Thanks so much! -

Hi all, I have tried for 6 years now to capture the elusive Pup from my northern location of Stockholm, Sweden, 59,2° N, almost thinking it would be beyond my reach. Not an easy task when Sirius culminates at less than 14° and the winter season is short with a lot of bad weather. I have used a CT-10 Newton from Orion Optics UK, a FLT-110 apo-refractor from William Optics, a Celestron 9,25, with and without Powemates of 2,5 and 4x, various cameras and filters. Last week I got the possibility to have an OMC-200 Mak from Orion Optics UK on loan. The mirror is handpollished to a sp

21st April: Re-processed to better show the colour of the fainter stars ... ....... Shimmering like a pearl to the naked eye, this open cluster of mostly young blue stars ( known as the "Pearl Cluster" ) is approximately 5500 light years from Earth and was discovered by Abbe Lacaille in 1752 from South Africa. This HDR image is constructed from 11 sets of exposures ranging from 1/4 sec ( to capture the centre of the brighter stars ) through to 240 seconds ( for the fainter stars of the Milky Way ). Total exposure time was around 5 hours. A Clus
