Not sure whose got his 6".  Most likely it is still in his house; his youngest daughter still hangs there I think.

I wish my ASI1600MC camera had arrived earlier, but at least I was able to get a parting shot at Mars although at 12" it's getting awfully small. This was taken with an AP130GTX, 5x Powermate, captured with SharpCap, 250/1000 in Registax:

thats a 12 incher and a 5x barlow? I would think there would be a bunchmore detail. thats only a bit better then my 6"f8 or was that with a 130 mm Im sory im a bit confused

 

I think the 12" refers to the size of Mars as being 12 arc-seconds.

The 12" refers to the SIZE of Mars at the time the photograph was taken in arc seconds (actually it was 12.3"). As indicated in the post, the telescope was a 5" APO (at F31.5 with a 5x TV Powermate). The seeing was pretty lousy - I'm surprised as much detail appeared given that it was hard to see almost anything visually....

Mars, becoming smaller and smaller...

I was actually hoping to see more Mars from your Q,  even small ones!

;)  Here you are!

Actually we enjoy clouds over Singapore continuously for almost one month. But today, sky was almost clear. Seeing was average to good.

Getting smaller.  Mediocre seeing doesn't help much either.

Attempted Mars last night, just for the heck of it. 01-08-2017.

 

It's very dim and distant. Hard to image.

Ok here's mars I shot last night with my C90, UNGUIDED (!) with an ASI120MC at max ROI so frame rates are low at 18FPS, the penalty for not having a driven mount. No matter how you cut it though, an 87mm unguided maksutov imaged Maria on a 4.7" mars and the seeing was hardly stellar. Hope you like.

Due to the overwhelming response to my 4.7" unguided mars image with my C90, here's still one even better at 4.6".

You're dedicated, Pete!  I got a couple of images of Mars last month, but can't motivate myself to try again this year.  But it is nice to be able to image it above the trees from my yard, a luxury I won't have around opposition in 2018.

I know it's the way it is with vid runs but the thing test comes back to me time and again is: keep the faith when running avi's.  It can seem redundant to keep shooting again  and sgain bug proof in the pudding is this image. 90 percent of all the vid I shot was lousy, maybe even 95%.  I had to really fish through all the processing to find the gem. I know, that's imaging , but it always reaffirms itself the next day when doing all the vids and then I'm so glad I gang in there and shot extra!

 

Thanks Ray!

 

Pete

I tried to image the conjunction of Mars and Venus this morning, but couldn't get them together on the ASI224MC's chip with my C6.  I did capture this cute little image of a 3.7" Mars, complete with north polar cap.

So let the small-bore Mars challenge of the new apparition begin!

Mars from this morning, just 19° above the horizon and about to disappear behind trees. Nexstar 6SE with ADC and 2x Barlow.  ASI224MC camera.

This is the Elysium Mons face of Mars.  At 6.8", small telescopes still can't resolve much detail, but I'm happy that the south polar cloud/ice can be made out in this image.

That's a little gem of an image Kiwiray! Your collimation and ADC tuning must be spot on.

Here's another little Mars image, from this morning.  If you look closely, you can see the cloud around Olympus Mons at upper right.

Details are getting just a little clearer with Mars at 7.5" this morning, although the increasing size is fighting the decreasing altitude, just 18°26' at this image's timestamp.

Those last few images are very nice indeed Ray! :waytogo:

 

I've been a bit remiss in not looking at this thread lately, some great efforts...& if you're reading this Pete your efforts are also very admirable with the little C90 & no drive..! :waytogo:

Thanks for checking in and commenting, Darryl!  Small-bore images of Mars at this distance are never going to get anyone's pulse racing, but I enjoy the challenge and seeing how resolution slowly improves as we get closer to opposition.  Mars is also convenient to image right now - I can get imaging done before work without losing sleep, although on most days I have lost sleep getting a collection of very mediocre Jupiter images.

I took this Mars image back on December 2, 2017.  It's the only one I have since starting to image about a year ago.  I need to rectify this.

Pretty good conditions this morning - I could make out surface details in the eyepiece.  Mars was 18°16' above the horizon.

Question, how do you track planets specially something small such as Mars/Uranus? i think Jupiter is big enough that is bright in the sky and sounds larger than Mars, Saturn is also big but so far so that it is almost same size as Mars from our skies.

I'm not sure I understand the question.  All three planets are bright and easy to find.  Once you align the telescope and have them on your computer screen, assuming your mount has some kind of tracking, keeping them onscreen isn't hard.  I have an alt-az mount and not very accurate tracking, so the planets wander quite a bit, but this just requires a few small, occasional adjustments to keep the planet within the imaging window.

Last one for now, as cloudy weather is predicted for the next few days.  This is from this morning, and may be the best I've got so far.
