Hello, we are glad and proud to announce that a new version of Siril has just been released and is now available to all users: Siril 0.9.7.
1 - Presentation:
Siril is (was ?) meant to be Iris for Linux (sirI-L), but is also now working on Windows (tested on 7, 8 and 10). It is an astronomical image processing tool, able to convert, pre-process images, help aligning them automatically or manually, stack them and enhance final images.
2 - How to install the release:
Each new version is produced with several packages for most OS we handled. We try to build maximum of packages and cheer you to check if a package does exist for your OS at this page: https://free-astro.o...tle=Siril:0.9.7
A packages is available for all these systems:
GNU/Linux (deb, rpm, appImage) OS X Windows 3 - New features:
Siril 0.9.7 is a stability release: it contains several bug fixes and some improvements over to the previous version, Siril v0.9.6.
The most important feature we implement in this new version is the new automatic registration algorithm. This algorithm uses a robust RANSAC routine that optimize the first search.
We sincerely hope you will enjoy using Siril and you will produce nice shots.

Hi to all you members on SGL.
I am a novice with 3 months experience with a SW200P dob, having started initially with a pair of Oregon 15 x 70 Bins on a tripod mount.
I have referenced some good books and spent some time with Stellarium and I am encouraged by my new learnt ability to navigate the night sky with the 200p.
I have connected my Nikon D600 (24mp full frame) DSLR to the scope and produced some satisfying photos of the moon, however I am interested in imaging some DSO's. ( I have caught the bug with no cure in sight!)
I intend to get a tracking mount such as a SW HEQ5 Pro Synscan, but for now would like to purchase a wide field refractor and produce some wide field imaging with a basic mount, I understand that subs of around 30 sec can be produced with mediocre results initially until I get a better mount. Also it would be nice to have a grab and go scope which is more convenient than the big DOB.
Also this would give me some images to experiment with the software such as DSS and Registax 6.
So, I have been researching three achromatic telescopes, The Skywatcher ST80 and ST102 (both come with kit mounts ranging from AZ3 to EQ1 and the Bresser Messier AR-102/600 (which looks stylish and has the Hex focus)
However, despite spending somewhere in the region of 4-5 hours so far researching for reviews on the BM102, nothing has been forthcoming>?
I am aware of the issues of CA with these small tube Achromats, however the plan is to Purchase one of the three now, save for the HEQ5 mount, then at a later stage use the scope purchased now as a guide scope and but a better APO doublet or triplet scope for the main tube.
So, having laid the table so to speak, which of the three would you advice and why please, I have been told by two companies stocking the BM102/600 that mechanically it is far superior to the two Skywatchers, but I am concerned that I cannot find ANY reviews on this OTA for its optical quality ?. I am aware that Synta make a few of these 80 and 100mm scopes for different suppliers but I am let to believe that the BM is a separate manufacturer.
Any advice or better still hearing from someone who owns the Bresser Messier AR-102/600 would be amazing, so thank you for reading this long post and thank you in advance of your reply.
I have a VERY heavy duty pan tilt Manfrotto tripod which I previously used to support my Sinar 5x4 Large format bellows camera so its very steady and has a pan tilt head already fitted, I intend to mount the new scope on this as an AZ to begin with.
Hey Guys, I have set my self a budget and after reading peoples recommendations, i've got some equipment together. I am new to this and before buying, i want to know if this set up is ideal ... Thanks In Advance, just want some reassurance haha Matthew

When I attach the camera to the telescope I get a white circle glare in the shape of the reflecting front mirror and its supports (see pics attached from the camera worse in some photos and you should see what I mean). Simply put my question is how to stop this, I notice it occurs during day time more prominently, is this normal and it;s just to bright or something for the camera? or is it something in the settings., all the details of my setup are below. Also without the camera looking through the eyepieces it is fine. Note I have just started astrophotography a few hour ago, so guess I am quite new to it, and its my first time using a non smartphone camera (took me 2 hours to take first picture due to learning I have to change the setting to allow pictures with lens off!).
Moon ~8pm 27/08/2017, from south UK (sun setting still a reasonably light). darker photo is with quicker shutter speed and have less glare but is still there.
