  2. Hi all, Not sure I'm in the right place or not but I was hoping someone could help... I have an Altair Astro GPCamV2 and the box tells you to get the software from http://cameras.altairastro.com/ and that it will only work with Windows! I was wondering if anyone else has gotten this type of cam working on a Linux os before and what the steps were for doing so. (Other software that will work, terminal commands for the drivers etc.) thank you in advance ?
  3. Hello guys, I'm on the look out for a Altair 60mm Straight Through Illuminated Finder Scope Kit 2" Focuser With Bracket & Base to use for auto guiding. I have been trying to get hold of one for a while but they seem to be out of stock everywhere! Here is a link to the item on Rother Valley Optics that I'm after: http://www.rothervalleyoptics.co.uk/altair-10-x-60mm-straight-through-illuminated-finder-scope-kit-2-focuser-with-bracket-base.html There is currently a wait of a few weeks (possibly) for stock to come in and on the Altair website but I was wondering if anyone had one not in use. Thanks a bunch, Tom
  4. Good evening members of the SGL collective, This is one of those questions that could be put into several different topics, but seeing as it's a beginner question with this particular bit of kit, I though I'd start here... I've recently invested in one of these: https://www.altairastro.com/Altair-GPCAM-50mm-Guide-Scope-Camera-Kit.html to add guiding to my set up. Because of the weather, I've only managed to get it outside once, but that was enough to raise a question. Incase you can't visit the link, it's a Altair 50mm Guide Scope Package with GPCAM Mono. With the package came with a short extender for the camera along with the associated cables for connectivity etc. Actually, the description of the kit contents on the website is spot on. However, what I can't find information on is the process for focusing the kit. On the only time I had this out under the stars, the only way I could achieve any sort of focus is partially pulling out the camera from guide scope. It just seemed like that there wasn't enough back focus on the guide scope by quite some margin. Eventually, I did get some sort of focus, although definitely by luck. It was sufficient to get the SharpCap software working though. So, what I was wondering is if there were any other SGL members who own this guide kit, and, if they have any words of wisdom to impart about its correct setup please? Thanks for your time everyone, Clear Skies, Tony
  5. Hi All I posted recently asking about suitability of using a 0.6 reducer with a 66mm scope....to cut a long story short I decided to get one and try it with my Megrez 72. I bought one (the Altair 0.6 reducer flattener) and it arrived yesterday ...however there are no instructions or diagrams whatsover included (not good) and I am wondering about the back focus spacing. After some searching online it seems the measurement is 55mm.....however I cant find a diagram of this exact reducer anywhere showing where to measure the distance from. I emailed the shop and they kindly replied saying they 'thought' it was from the lens of the reducer itself but not sure. Usually there is a point on the reducer like a certain shoulder to measure the distance to your camera sensor from. Does anyone have this reducer and know where to measure from? ...or a link to a diagram? Thanks in advance Tom
  6. Took these last week. The first is a wide field of the area around the constellation Aquila. I did not intend to image Barnards E, i never even knew it was there! I just pointed the camera at that area as i knew there would be some nice dusty stuff floating around was quite surprised when the first exposure came in showing the 'E'. I used the Canon 50mm 1.8 for this image with a Canon 1100D unmodded. I now intend to for this to be the first panel of a mosaic i hope to crack on with. The second image is again of Barnard's E but shot with the 200mm for a closer look! I had a lot of trouble with the second image. I was getting a blurry result from Deep Sky Stacker which was very frustrating! But thanks to some fellow imagers the problem was sorted. Too many stars, DSS was finding over 30,000! So i had to move the slider (which i hadn't touched in months) up to 70%. Also, the stars are a bit trailed also due to polar scope collimation issues. And i may as well throw in this image of Cassiopeia which was also shot with the nifty fifty! The more i use this lens the more i love it Thanks for looking Clear skies
  7. Hi All, I have for sale my Altair GPCAMv2 130 Mono Guide / Imaging / EAA Camera Brilliant Guide Camera and in immaculate condition. Link to Altair's advert: - https://www.altairastro.com/Altair-GPCAMv2-130-Mono-Guide-Imaging-Camera.html Paid £189.99, want £125 including postage, Payment preferably via Bank Transfer or via PayPal with you paying the fees or sending as Friends.If you are quick then can get to you before Xmas. Specs as follows: - Sensor & performance specifications: ALTAIRGP130M: APTINA AR0130 MONO CMOS sensor Sensor Size: 1/3" (4.8x3.6mm) Exposure duration shortest/longest: 0.115ms (0.000115 secs) / 800 secs 13.33mins (trigger mode) 0.115ms (0.000115 secs) / 5000ms (5 secs) (video mode) Bit depth: 8bit & 12bit mode switchable Pixel size microns: 3.75x3.75 um Resolution in pixels: 1280x960 Recording System: Still Picture and Video Region of Interest (ROI) support: Yes, in SharpCap & AltairCapture Approx. Max frame rates (assuming computer Bus and Hard Drive operating at full bandwidth)*: 8 bit mode: 1280x960 - 27-30fps 640x480 - 55fps ROI mode 320x240 - 104fps ROI mode 12 bit mode - approx 50% of above. * Based on average user reports. May be revised with more data. Shorter exposure durations yield faster frame rates. An expensive PC does not guarantee a fast frame rate. Sensor QE / Quantum Efficiency: Approx. 78% Gain Sensitivity: 6.5V/ lux-sec Dynamic Range: 82dB SNR Maximum: 44dB Readout: Progressive Scan Shutter: Electronic Rolling Shutter I've used it a handful of times with Metaguide and it worked perfectly. You can download the software or if you need I can burn it to CD.
  8. Hi folks, thought I'd post here as more people here seem to be using the Live Stacking feature of SharpCap now. SharpCap - if you haven't encountered it before - is a free Astro-focused capture application for Windows. SharpCap includes support for a wide range of cameras - including QHY, ZWO, Basler, QHY, Webcams, Frame Grabbers, ASCOM and others. Any camera that SharpCap supports can be used in live stacking mode, although to get decent results you will need to be able to set exposure lengths of about 1s or more. Live Stacking includes an alignment option (on by default) that will correct for drift and field rotation in each new frame as it is stacked. Alignment depends on being able to detect at least 3 stars in each frame. Additionally you can filter incoming frames based on a FWHM measurement of the stars detected, allowing frames with better seeing conditions to be stacked and worse frames discarded. There are simple functions allowing the histogram of the stacked image to be stretched for display and the stack can be saved either 'as seen' with the stretch applied in PNG format or in FITS format with no stretch applied for later post-processing. SharpCap also has an embedded scripting language which allows simple programs to be written that will automate a capture session - some users over on Cloudy Nights have been using this facility to automatically stack a target for say 30 minutes then move the mount to point at a new target and start stacking that. SharpCap 2.9 is currently in beta and will contain improvements to the live stacking features including an easier-to-use histogram stretch function, more star detection options for alignment and automatically remembering most stack related options. However, if you prefer to avoid beta software, feel free to use SharpCap 2.8 instead. Just as a taster, here is an M81 I produced in 30 minutes of 4s exposures with the ASI1600MM-Cool. This was really just a test stack - taken on first-light with the camera, testing a new version of SharpCap and with a whole bunch of other things in my setup changed - I'm sure it's possible to do better when hurrying a little less! I'd love to hear any feedback people have on how to improve the live stacking feature - and see any images you capture with it! cheers, Robin PS. For about the first 10 minutes of stacking I had left the mount accidentally on Lunar tracking rate having used the moon earlier to sort out focus and align the finder scope. The alignment feature took care of this quite happily and I didn't even notice until I spotted a little line of hot pixels building up due to the drift.
  9. Hi, I'm looking at getting a short focal length, wide field scope to add to my equipment list if possible. Uses will mainly be wide field visual, some EAA, and a gentle 'dip the toe' into imaging. There seems to be a wealth of choice currently, especially offered from TS and Altair. Ideally looking at the 60 to 70mm offerings from Altair but would consider others. Many thanks for reading,
