Dean: You say 'the mount will continue to slew'. Are you saying the mount is running away at high speed? If this is the case, I'm betting you have a power supply problem. I've seen this happen when

almost by <snip> itself capable scopes and I like this comment in particular! I often ask myself how much I am depriving myself with my (older) ST-2000XM and then I see such work and results using

Dean: Don't know, but........ For years, doing fim imaging with exposures of 30 minutes to 1 hour, I first used the Polar Alignment Scope (boresighted) and then a drift alignment. When I moved to CCD

Rolando, Both are exceptional. I like your M17 and the 80 minutes total exposure! Awesome. I also like your idea of mixing the H-a and O-III to derive the green. ;-) Anthony. band images

and that is exactly why I : 1) have actively promoted narrowband since early 2003 as a viable method of imaging nebulae from the 'burbs 2) note that an optimization for the camera is to go with a

Hi Roland, I'm not a big fan of False-color (e.g. narrowband) images because almost by definition no attempt is made to match colors to reality. Sometimes to get interesting colors the SII and OIII

Hi Ray, In the past I have limited myself to taking only RGB images. Now that large box stores are within shouting distance of our factory and observatory, I can no longer get anything reasonable

So which mount was it that facilitated your capturing these beautiful images? -ER

Absolutely the mount is the key ingredient for me to be able to image at 5760mm and even at 3366mm were the filters you used the baader planetarium narrowbands? i sure like my set, you just can't

those came out very nice roland based on postings from others today I suppose consistency would say the image postings are off topic here, but I think that's not a proper interpretation of the spirit

I have a 2002 mount/keypad that very occasionally does the same thing- also one that has been well-looked after, in an observtory. It is definitely a problem with the keypad. This keypad also has a

i agree, however given the tone of several posts appearing in this group it appeared that an explanation was warranted irrespective of the topic to which it was addressed. George LaBelle

Or ... Ray, As the years wear on, and you can no longer carry all that luggage to a dark site, and very soon, not even find one, within the cost of gas, squeezed out of your life savings - it will

Hi George, Yes, I agree that this is off topic. But there is the moral of the story... you should try to take your AP GTO mount to a dark site as it can make a huge difference in image S/N, even when

Hi folks, I have posted some new images I took recently with the first of the 140 refractors on Robert Provin's website, NGC6888 and M17: http://geogdata.csun.edu/~voltaire/roland/ Be sure to

Dear Rolando, First of all thank you very much for your fast and detailed response. If I work with the keypad installed (no EXT), everything is fine - no problem with pier flips and pointing -
