Welcome to ECA. This is an amazing group. From my old DSLR days befor I bought a CCD andLight box for $200. I bought a 12" piece of Milky White plastic. I would go outside around dusk and point the scope facing east ( away from sun) to clear blue skys. Put the plastic over end of scope, Put the camera on I think AV and shoot 10-20 shots of clear blue sky. I think people have also used a T-shirt to put over the scope. This is a cheap way to do it, but once you take the shots, you can not move the camera at all.
You're on the right track. Flats, Bias, and Dark frames are critical.

These are truly excellent shots. Do you think that IP could have done as well as Registax 6?
« on: June 26, 2013, 09:20:08 AM »
Thanks C & T, Mike. I will try to re-process stopping IP at the 90-150 seconds.

Thanks C & T. I did not know that. I appreciate the advice.

It is very nice to see some new images for a change. I finally got out last week and did a saturn shot. I think it's musch better than my yellow shot last year. Here are some specs: 5 minute video with Imaging Source DFK.21AU618 color camera.
Celestron Edge C8
Televue Powermate 2.5
Images Plus ver 4.5

Excellent, I think I like the Modified HST the best.

Wow, This is truly amazing. What a horrible winter we have had. I personally have gone through mount hell. My G11 Gemini 1 went out in november, and spent a month trying to get it right, ended upgrading to Gemini 2. Then 3 monthe of winter. Tried last weekend to get M81-m82 and could not get mount to Guide, finally got right ASCOM drivers and worked tonight. Another month would be great to try and get M81. For the record Gemini 2 rocks. Hopefully we can get some clear skys, this has been The worst winter ever.

Ben, not sure if this will help. When I bought my ST8300C, I had egg stars in the corners. It came from the 56mm rule of focus for refractors. I ended up buying a 10mm, 2mm, and a 1/2mm extenders to go with the 25mm and SFF7 field Flatener. Hope this helps a little. The ST8300 has a 17.5mm backfocus.

Congratulations, I saw them in the magazine. You two do amazing things with your rig.

That is really an excellent shot. Much better than the first. Lots of detail.

Hi Bob, the exposure time was around 2.5 hours on each.
« on: September 12, 2012, 11:34:49 PM »
Hi Bob, I have been laying low on this one because I am from the Light Side. I use an SBIG ST8300C. My main problem is like yours, a serious lack of time to shoot. I am very lucky to get in 5-6 hours a month, so with issues that leaves about nothing. I still have my Hap Griffen modified Canon T1i, and will keep it forever. But the SBIG is a major upgrade, with cooling to -40, and very good sensitivity. To me it's definitly not as good as a Mono CCD, but a major upgrade over the SLR. This kind of an unfair comparison, but might help.
2011 is SV105 with SBIG
2010 is Orion ED 110 with T1i

Thanks Jason, I really missed the group.

I used to have a CGEM and the connection for laptop is from the Hand Remote. You will need these 2 items: From the Celestron Website:
Cable, Nexstar RS-232 Item # 93920 $15.95
Cable, USB to RS-232 Converter Item #18775 $44.95 (or generic)
Hope this helps.

I agree, that is one of the best M13, I have ever seen.

I think it looks really good. Lots of detail.
Question about the Preasure Tuner, You seem to have a lot of surface detail, Is the PT a must have? Or is the basic tuner good enough.

Very nice dave. Can't wait for more.
« on: July 09, 2012, 10:37:22 PM »
Thanks, hopefully I will get better. Looking forward to trying it with the 8" Edge C8.

I forgot to post this one. I recently got a DFK21 AU 618 color camera. Nice camera. I took this shot of Saturn with my SV105 with a 2x barlow. If I remember right it was the best 300 of 1200 frames taken with IC Capture, and stacked and processed in Images Plus 4.5.

WOW, your pic's are always incredible. I have been lusting after a Lunt for a while now. I recently bought a DFK21 AU 618 for planetary and sun shots.
It looks like the basic Ls60 with the B1200 would do very good with my camera. Keep em coming, thery are as good or better than anything I have ever looked at.

Excellent Shot of the Iris nebula. I confess i voted for yours also. Mine had way too many issues. Congrats.

Here is my attempt at NGC 7023. I found I had a dew buildup on ST8300C. I did 40 @ 300s subs with my SV105T. ended up cleaning SBIG and redid flats, but that created different issues. Anyhow lots of PS3 edits to try and clean up, but now much luck. But it was fun trying.
« on: June 30, 2012, 10:41:31 AM »
That is very nice. Have to try it someday.
« on: June 01, 2012, 01:56:01 PM »
Very nice David. Looks like a winner.

Very nice Joe. I really like Narrowband imaging.

That's some really great setups. was able to get mine tracking last night.
