Thank you Don Just when I think this hobby is getting a little bit easier, along comes another set of problems. Now, we just need some clear skies.... Eddie...
Cool processing technique. i've got to look this over more thoroughly. Thanks for the added info. Happy New Year, Wayne http://www.wayne-cooper.com ... because...
The west coast has been hit be fairly hard rain storms lately. Last night it began clearing (just in time for the Rose Parade)and this morning at 1:30am I...
I imaged Q2 Machholz and have a movie showing its motion across the sky during a 96 minute period. The comet was clearly visible under the full moon with the...
Thanks much Bob, At least someone welcomed me :<( The MI-250 is very nice. I'm a big fan of one-shots as you can see, and am partial to the SX's Sony ExView...
Hi Warren, Welcome to the group...great website! Looking forward to your participation and contribution. Randy Nulman http://www.nulman.darkhorizons.org ... ...
This looks great, Josch. This is one of those nebulas that rewards longer and longer exposures. Your exposure is about the same as mine (2:40 from a few years...
There is nothing about that feature that would restrict it to beginners. I've used it for years, but I also use other software at times. If you are taking more...
Can you send me some sample images to look at? This is a very unusual problem, haven't seen anything like this before. It would help to see some first-hand...
A polar alignment that is not correct will produce drift in both RA and DEC. The errors in altitude and azimuth are easiest to see in different portions of...
The weather has not been very clear for several days. I get a break in the clouds once in a while and keep experimenting. Seems I figure out a little something...
Thanks, your explanation is very lucid. I think I understand better. Its been about 30 years since I did any r d theta and coordinate transformation stuff...
Was curious Never done it but can one scale darks? Not temp just from 1x to 2x? Thank you Mark www.aajonahfish.com/astronomyhaven.htm ... No virus found in...
Yes, with some caveats. You'll need to subtract a bias frame or a bias offset first to scale the dark frame properly. Usually, it is better to scale darks...
Thank you Same time same temp Just have 1x darks a file of 40 of them and 0 of them in the 2x file I need them in 2x So sounds like it may be alright then Mark...
I think I understand now: did you mean that the image is binned 2x2, but the dark is binned 1x1? If so, it is not going to work, I'm afraid. Binning mode for...
Are you talking binning? If so, no - you can't resize a dark. If you are talking time, yes - you must have a bias frame so that the software can subtract the...

Hello group and happy new year!!! My question is if i can use focal reducer 6.3 with the ao7 , with Nexstar 11 sbig 2000xm , and cfw 8a. Last time a few...
... Ted Agos makes a focal reducer that will work with the AO-7. Check out http://www.ziplink.net/~lester/FLR.html and see if it will work with your setup. You...
Hello. I have just processed this brief image of comet Machholz. It is only the blue channel, 6 x 2 minutes summed. I was getting my set up sorted to take a...
I have been using T-Point mapping runs to establish my polar alignment with an ME mount. Although GOTOs have been excellent across the entire sky, I still...
Hello and Happy New Year, To answer you question, yes you can. I use the same exact set-up on my C11. F3.3 wont come to focus with the AO-7 in the path, but...
From what I have found T-point will give you your alignment in relationship to the WHOLE sky A drift alignment will polar align your mount in that particular...
Hi, Ted Agos .63 focal reducer for the AO7 works very well. I believe he makes a .33 reducer modification but with the ST2000 you will probably get a lot of...
Thanks so much Randy! Is there any semi-serious imager(s) getting good guiding with a stock G-11? Perhaps you're running an STV? I'd like to talk to you. I'm...
