So... A type II-P discovered after its rise and on the plateau? Then we have plenty of time to keep trying for it visually but it will not get any brighter.

From our Galaxy Log blog with M-65 in 2008 and from this past week. I have not had a chance to visually go for it.

Thanks, and you can see the full size image at the GL blog. FrankC is our (CAS plus Galaxy Log) "lead" imager and also my B.P., for I'm not into astro-imaging... just an eyepiece guy :refractor: :dob:

I was unsuccessful last night in detecting SN 2013am using the ASH 17" f/15 classical Cassegrain at magnifications as high as 462x. I didn't really expect to be able to see it, so I wasn't terribly disappointed. ;)

That's a shame Dave - got another shot last night and SN unchanged. I'm beginning to suspect it's not going to get brighter as it should have by now :o

That's discouraging for visual, gentlemen. Well, tonight is the best chance for good transparency in a clear moonless sky for April here, but the seeing is going to be atrocious, plus the wind (vibrations). I plan on observing M65 anyway, but seeing this particular SN seems out of question in these conditions...

Poor seeing is better than seeing snowflakes. I'm going to give it a try tonight.

Here is the sketch I made last night (16", blue zone). The SN was invisible. It was supposed to be just N or on the N edge of the inner separated star cloud on the S end of the galaxy. However, even 450x with an Abbe II orthoscopic could not bring out the star or subdue the star cloud appreciably. I did not go higher due to seeing, which started out bad in the evening and was only approaching average before moonrise.

EDIT: I oriented the sketch conventionally (N up, W right).

No, I can not see it visually but this picture was taken with my CPC1100 SCT Celestron ALT / AZ mount from south Sweden in April 1 at 23:30. The camera is my new Bright Star MAMMUT color CCD IMAGER with focal reducer around f / 3. A simple image with a exposure time of 40 seconds and no image processing (no flat, dark
or bias).

IVM, excellent sketch! I tried last night but no luck. I thought it would brighten but alas, its not. Well, there will be more I'm sure in other Messier galaxies that will be visible. Just read a study about identifying RSG and WR stars in M101. There will be others in M101 over time, probably in my life time.

I plan to try for this one tonight. I don't expect to succeed but I might. I have a 20" but my skies are only around 5.3 NELM.

Good luck with your 20" - your 5.3 NELM seem like 'heaven' with mine rarely better than 3.5 NELM - at least my sky isn't 'cluttered with stars' :roflmao:
Here's my 30s shot from last night

I tried with no luck Thursday night from a green site with only average conditions. All night the galaxy views never "popped" like they do on a good to great night out. Still better than not observing from the couch. :grin:

Two fellow CAS members and I observed SN 2013am on Friday night from one of the best "local" dark sites. I caught fleeting glimpses of it through a 22" SDM Dob at high magnification. The owner of a 17.5" TeleKit Dob with a Zambuto mirror said he was able to see it about 60% of the time through his scope.

Some other CAS members viewed the supernova from a different site that night.

I did end up trying Friday night. I was using my 20" f/5. Transparency was OK but not great. Like someone else said earlier, galaxies just weren't popping. I was able to see the star that is near the nucleus of M65 but the SN was not to be seen. Still, it was worth the visit and I enjoyed the trio. This was one of the first set of galaxies I learned to find way way back in the day so a visit is always brings back a little bit of nostalgia.

On Friday night the seeing was supposed to be bad again but I noticed that from time to time I was actually able to see Airy disks. I was on M66 with my 16" and moved over to M65 to try for the SN at 225, 300, and 450x with ZAOIIs. Again no SN did I see, and not even the star W of the core which is comparable.

Saturday night with my 20" f 4.5 using Meade 14mm & 8.8mm 4000(163X & 260X) with average seeing, I spent ~ 20 minutes observing M 65. Like others, I could make out several superimposed stars on the galaxy but could not pull out the SN. Due to the seeing, 16 mag was the limit that night. It was fun trying anyway.

I also struck out on this one tonight; seeing was a bit soft and I don't think I was getting much deeper than mag 15 on point sources. There were two moments where I had a momentary flicker in averted vision at about 400X, but I don't put any credence in those. Fortunately, I had better luck with the SN in ngc 2554.

Here's the image of M65 and SN 2013am that I received yesterday from the Bradford Robotic Telescope. It's a 110 second exposure that was captured with the BRT's 14" f/11 Celestron SCT and FLI MicroLine camera.

Nice image Dave - when was it taken? I recorded it tonight Apr 11 and it seems to have faded from my pic of Apr 5. It was as bright as the star immediately west [right] of the gxy core. Bright Supernova latest pic Apr 8 and mag seems constantish :o Will post my pic tomorrow :rainbow:

Thanks Dave - your pic ~44hrs before mine from last night timed Apr 11 @ 21.01UT and I'm sure the SN has faded to ~m17.1 from my last pic of Apr 5 some 6 days ago - both in image below ;)

Tonight's shot Apr 15 under very poor transparencey eg NELM 3.4. I suspect the SN had dropped below visual :o

have a shot of M65 taken 4/5/13 @05 UT that shows the supernova. :confused: I'm a little confused as how to show it in a post??
