  1. Before I purchase one, I’m wondering if anyone has a 50 or 60 mm RACI with illuminated eyepiece they would like to sell? Thanks Andy.
  2. Just took the Skywatcher 80mm Pro outside to align the finder scope. It was pretty easy to do. The ridge line you see in the distance has a radar site on top of it. It’s many miles away. My question is, how well do these finder scopes hold their setup? How often should I check it?
  3. Anyone have experience mounting a finder scope/autoguider (Orion Deluxe Mini 50mm Guide Scope) onto the hotshoe plate on the top of a DSLR camera? The finder scope has a 1 1/4" dovetail base (shoe) and also a adapter plate but I need something with a hotshoe fitting on one side and a plate or a dovetail female on the other. Thanks, Lloyd
  4. Hello all! I am mounting an Explore Scientific 8x50 Right Angle Erect Image Illuminated Finder Scope on my Skywatcher Dobsonian. The original Skywatcher mount only had one bolt hole. The Explore Scientific base requires two bolts. I was told to make sure to have the primary mirror cover in place and to place a cotton sock over the secondary mirror. My concern is drilling into the tube itself. Are there any other precautions I need to take so that that it doesn’t look like it was drilled by a bunch of Wallys? LoL! Greg
  5. Hi everyone, I’m putting a shopping list together for an astrophotography setup and I could really do with a bit of advice on my options thus far. My aim is to photograph DSO’s (I’m really keen on imaging galaxies) I need a rig that is easy to set up and also portable as I plan to transport it to the darkest skies I have available to me. I’ve been shooting wide field astrophotography with a DSLR and a tripod for about 5 years now so I already own a modified Sony A7S and an unmodified Canon 5D Mk3, so I will start by shooting with these bodies. I'm still undecided on scope and mount, hence the list has options. My list so far: Telescope: Orion ED80 WIlliam Optics GT81 Explore Scientific 80 Essentials Mount: EQ6 HEQ5 Finder Scope and CCD for Guiding: Orion Mini 50mm Guidescope Meade DSI Colour I intend on using PHD for guiding. I also need other accessories such as field flatteners etc, so any advice on 'the extras' would also be greatly appreciated. I don't expect to get hubble-esque images from this rig! I would like to go down the refractor route, but other than M31 which is, of course, rather large, are these telescopes going to be any good for galaxies? It is one of the reasons I am leaning towards the Orion ED80 as the scope for that extra 120mm of focal length as all the scopes listed are f/6. I'm also leaning towards the EQ6 for the mount but any other suggestions are more than welcome. Thanks is advance!
  6. Hi! I am afraid that I am on the scrounge for information again from the good people of SGL - one day I hope to be able to give back to this forum as much as I am receiving in these early days. But for now I am mainly all take! I am starting to look at guiding for my astrophotography having read a few posts here and there about using a webcam as a guide camera. There is no way at the moment I can afford a dedicated guiding system - scope & camera. I know from reading other posts to questions similar to this that I can use PHD together with EQMOD to run the mount and that you can use a webcam in certain situations as a guide camera. My question is: do you keep the original lens on the webcam and use it Afocal; or do you take the lens off and direct the light straight onto the chip as you do with imaging with a webcam? I wanted to try this system with my CG5 Advanced GT (this mount has the auto guide port) to see if the other equipment I have (laptop, power pack etc.) can handle it before I start to spend out on more advanced stuff at some point in the future. I have a 6x30 finder scope on my C8 but I also have a 20x50 Mirador spotting scope that I thought I could mount on the main tube if that would be better to use as a guide scope. I appreciate that the magnification on the spotting scope is a bit high but I am using what I have got in order to save money! I hope to be getting a second hand DSLR soon which I will be using for imaging rather than the Philips SPC900NC which I am using at the moment. The SPC900 could then become my guide cam (if it doesn't need its lens ).
  7. Having just read this great guide here on PHD:http://stargazerslounge.com/topic/188777-phd-guiding-basic-use-and-troubleshooting/ Would people be willing to post up their settings so as to give people a known starting point that works or at least a good starting point?As I think it's hard to know what settings to choose in PHD. Something along the lines of: Webcam model: SPC900 Type of guide scope: 9X50 Skywatcher finder scope Then list your settings for PHD This way,it can be kept all in one place for future reference.Sound like a good idea or a non starter?
