Now living in the UK means that a tin of beans costs twice as much as in the US. Then on top of that if any reference is made to astronomy the price increases...
I skimmed the information and images on the Australian reducer, and the first thing that caught my eye was the elongated stars in the sample images, and the...
You can easily measure differential flexure. Set up both scopes to guide, but only one of them is actually guiding. The other one is guiding with corrections...
Randy I purchased the 19" ViewSonic UltraBrite A90f+ a short while back and have been very pleased with it. I had to step up from a 17" to at least get half of...
hi, An image of Saturn taken with my orange tube c8 and a Toucam. Taken at f20 resulting in .28arcsec/pixel resolution. 2000 frames stacked in Registax and...
Hi All, I got a private email from Ron B. that he did the bench test last night (Thanks Ron!). In his test, there was virtually no difference in fwhm between...
Can anyone tell me the practical differences between a 10nm bandpass H-alpha filter and a 13nm bandpass one? What are the pros and cons, or is there really...
Peter, I'm a retired US type in the UK whose pension is in US $, so know well what you mean. Monthly income has dropped by 30% in last few months due to ...
I import most of my stuff, so far its been 3 EP's, 1 Nikon CP5000 & my LX200. I had already worked out the maths & even after import & shipment I saved over...
Hi Larry, That's a very fine Saturn. You have captured some good data. I think you might be able to increase the contrast a tad by raising the black point. ...
Hi All, I finally got some time to finish up a few image series started about 4 months ago takien with an RCOS 20 and IMG6303E camera all in 2x2 bin mode for ...
Very nice - I can see the crepe ring. Ron Wodaski The New CCD Astronomy Book http://www.newastro.com/ipb ... From: laurenc319 [mailto:laurenc319@...] Sent:...
Both of those are fairly wide-band filters. They will let in Ha, but they will also let in light that is near Ha. This will reduce the contrast of the Ha...
Hi Everyone, I am looking for a recommendation. I currently own a Pixcel255 which I would like to upgrade. I have pushed this to its limits and want something...
Excellent M106, Brian. A nice test is the star/galaxy pair at 3 o'clock from the galactic core. You've resolved it nicely with some good detail in the little...
Steve, I don't know enough about the SX cameras to comment. I'm sure others will chime in. On the SBIG side, if you went with the 237 I think you would soon...
Hi John, Thanks! I did see that galaxy pop up after a bit of deconvolution showed the arms. I checked this area out on Adam Block's superbly detailed version...
I've used both SBIG and SX cameras. The specialization of the two lines seems fairly different. The SBIG cameras are largely designed for maximum functionality...
The Albuquerque Astronomical Society (TAAS), a non-profit organization of New Mexico amateur astronomers, is now selling a computer screen saver featuring...
Alan has certainly give some good reasons in favor of the SX cameras. I am a huge fan of the SBIG cameras, and I must take gentle exception to the statement...
... cameras. I ... exception to ... criteria, ... criterion. Looking back at what I wrote, I should have prefaced the "vastly better" with something like "for...
I do not want to see a protracted SX/SBIG debate, so I'll try to put some oil on the waters and offer a comprehensive viewpoint. <G> Mark's points about the SX...
Hi Folks: I'm just back from WSP. The weather wasn't great with only 2 1-2 good nights for imaging, but it was still a great star party. Of course I just had...
I have an LX200GPS 10" and a Digital Rebel and have tried using the LPI (with a meade off-axis guider) for auto guiding. It works if I don't have a focal...
Bob, Great images, I was only able to get three images and not even finish up all three with complete data, and in fact my Centauras A I was not able to get...
