With several clear nights over the past week, I've been playing with the Synscan Pro app (Android) in conjunction with a Synscan WiFi adapter on an EQ3Pro mount. I have to say I'm generally quite impressed. Much cheaper than buying a traditional handset. However, this evening I was trying to "creep up" on the Andromeda Galaxy by star hopping towards it via Mirach, Mu Andromedae and Nu Andromedae. Mirach was no problem but the other stars were not available for selection in the app. Am I missing something? I couldn't find any way to enter an SAO number or any other catalogue number to find the minor stars. Is this a limitation of the app? Or the adapter perhaps? Or is it me? Clear skies, Mark. -
NGC6559 at the center of the milkyway is a photo I created from RGB filters only and at BIN1. Telescope: ASA 12'' F3.6 Mount: DDM 85 Unguided Camera: FLI 16200 Mono Filters: Astrodon Thanks for watching Haim Huli My Flickr Page: https://www.flickr.com/photos/101543943@N04/

Hi, does anybody know if stars differ in color when viewed through different sets of binoculars (ex. 7x35, 10x50, 11x80, 20x80)?

I recently got hands on my first equatorial mount, a Celestron Advanced VX mount.. And the curse holds true, that after purchasing new gear, you are to bear the burden of weeks of bad weather! So whenever there has been minor holes in the clouds, I've been out practicing star alignment, polar alignment, and just the general behavior of the mount, pointing at any star that would glance through the thin cloud cover. Hope to soon be able to practice drift alignment. A patch of "clear sky" showed itself a few nights ago, so I thought I would try and see how far I could push the unguided exposures (having only done the ASPA). And even though thin clouds would regularly pass over the target, I am at least pleased that I could squeeze this out of the image. +- 1 minute exposures of the center of the noble M45, Pleiades. 5-6 shots later, the clouds came rolling in again... So here I am stuck looking at my mount collecting dust and browsing these forums again Looks like there is some coma that needs fixing too. Scope is the Celestron 130 SLT OTA. Using a barlow right now to achieve focus. Trying to obtain the screws needed to move the mirror. As a bonus, I noticed the presence of a magnitude 17.2 in this one, faintest I've caught yet I think.

Here is the North American Nebula in the Hubble pallet and HA. I'm still a relative novice to the Hubble pallet adjustment and didn't want to overcook it? Most probably it can be pushed a little further? The image was capture using the trusty ST10 and the BabyQ FSQ85 over the course of this month. I have been battling with the weather to complete this before my holidays start tomorrow!!! 12x 800sec HA 17x 600sec OIII (2x2binned) 15x 600sec SII (2x2binned) I binned the OIII and SII since these are very weak in the nebula and don't contribute much in the way of detail. The HA data has been used as the GREEN channel and also a Luminance channel for the final image. The HA data is a little wider since I have had some small alignment issues between sessions, still setting up and tearing down my kit each night / session This is the alternative colour schema, I suppose that there is no wrong or right colour schema its just down to your personal preference? Which one do you like?

One of my first targets but still trying to get a decent image - clusters are harder than they look to capture due to them being all stars so tracking errors and uncorrected optical problems are very quick to show up in the end result.© Aenima

Hello fellow astronomers, Proudly announcing the southern hemispheres NZ astronomy main event opening every Sunday from 7.30 pm, from the 7th April. We welcome visitors and can accommodate you in our beautiful, dark, southern town. Please contact dunedin.astronomy@gmail.com Kia Ora! p.s This is Dunedin, New Zealand, not Dunedin, FL! -
Hi all, Sorry if this has been asked before but every time i do research in to this i get different answers from different sauces. Not sure if im looking at out dated information or not so im hoping if i ask my questions here i can get the most up to date answer. So my questions are; 1. How many Stars are their in our Galaxy? 2. How many Galaxies are their in our Local Group? 3. How many Galaxy Clusters are their in our Local Supercluster? 4. How many Superclusters have we found so far? 5. How many starts in total are their in all of the Superclusters?

Hi All Took this beautiful nebula also knows as Tor's Helmet during my visit to Namibia this year. Finally got a few nights to process the raw images to the photo you see here. Photo Details: Ha: 1.4 Hours OIII: 35 Min SII: 25 Min RGB: 15Min each. Telescope: ASA 12'' Astrograph F3.6 Mount: ASA DDM85 Camera: FLI8300 Mono Thanks for watching, Haim Huli

I've been absent for the forums for a while as I packed up my telescope with an impending house move. Which has now taken place and the telescope will be retrieved from safe storage. However a few nights ago I sat out in my new garden looking at the night sky. I grabbed my trusty Canon 40d and set up my tripod. Attached are some of the images taken. -

Here's an image that i just finished processing after finding the lights that were taken months ago on a memory stick that i was emptying and had forgotten about, only had the lights so took some darks this morning by using the chip temp shown in images taken via Backyard Eos. I reckon there's 19˚c between ambient and full speed on my 550d so put it in the workshop with the heating off and seemed to match them well. Needs some more data and my processing is all that but I'm quite happy with it for a surprise find. This image was taken with a Skywatcher 200p, Heq5 Guided via PHD Canon 55D unmodded, Backyard Eos 24 x 180s Lights @ 1600iso 19 x 180s Darks only (taken months later by matching chip temp) Processed in Nebulosity, CS6

Globular clusters, whenever I point my scope towards 95% of them they come out as a hazy patch. The only two globulars I can see kind of clearly are the Hercules cluster and Messier 3 in Canes Venetici. All the rest look fuzzy, What aperture would you need to see them clearly? I have a 4.5" reflector. Thanks Adam

finally sorted out the videos on my desktop machine so I could get the colour balance right Starry skies - 1000 x 5 second exposures over 90 minutes and 2480 raw exposures make up this Cloud timelapse over 8 hours as always best viewed on Youtube in full screen

National Geographic 90/1250 maksutov is my telescope and thanks for all the replies and support of my previous post it helped me alot and i figured out how to see the moon for example in beautiful quality but there's the problem i have. I can only see good views and a sharp sight of the moon but that's about it. Do i need a better lens that can zoom even more out or is this the limit of my telescope? Please let me know if you know a solution to this. -
I’ve been looking up st the Stars with Telescopes I’d put together from various other scopes, but late last year I decided to get more involved with it. I’ve purchased at least 15 books on Astronomy. I’m starting to piece together how the start Charts and Math and which tools are best used on the subject of Astronomy and so far self taught. I don’t know anyone else that’s doing it. I stumbled into this site looking for something totally unrelated and just see what’s here. I’m primarily interested in just about everything on the subject. Maybe I should have did this early. Hello everyone.

Wide-Angle Shot of Western Sky (16th April 2017)
Atlantean98 posted a gallery image in Member's Album
From the album: Wide-Angle Shots
Obviously it isn't the best of pictures due to the fact i live in North-West London, and I have a Fujifilm FinePix S9500, but i go to my local Nature reserve which borders the outside of London with Hertfordshire to take amazing pictures like this one! The Wide-Angle Shot is at f/2.8 and the exposure time of 20 seconds, the ISO Speed is ISO 400 and the focal length of 6mm. It was taken toward the western sky at approximately 20:00-22:00, on the 16th April 2017. -

In my search for Comets at the moment, I had a night outside on a clear evening last week. I cannot wait until Comet ISON makes it's way round.
